power catamaran hybrid

The 2024 “Boat of the Year” is an award winning, eco-friendly cruising yacht, designed from the ground up with electrification in mind. For those seeking “the yacht of the future” with a perfect balance of style, performance, safety and comfort, the future is now…

The HH44 is packed with innovation.

Designed from the ground up for electrification and to maximize the solar array, the helms are move aft to free up the coach roof.

Folding transoms enhance safety at sea, and open at anchor to increase living space and provide an easy connection with the water.

Helms rotate in and out for protection, visibility, and an enhanced sailing experience.

Forward window open vertically to increase air flow and interior comfort.

C-shaped daggerboards provide vertical lift and impressive upwind sailing performance.

These are just a few of the innovative ideas being incorporated into this impressive new yacht.

The HH44 features luxury unlike any other 44’ catamaran.

Special attention has been paid to achieving a level of luxury not typically found on a cruising catamaran of this size. Headroom exceeds 2m (6’6”) in the salon and 1.96m (6’4”) in the hulls. Lines are hidden under deck to keep walkways clear, and push button controls adjust the traveler as standard.

Thick and plush outdoor foam cushions surround the cockpit, creating a social and comfortable outdoor space. A clean aft beam, with davit winches hidden below and mainsheet traveller on the cabin top, creates a safer cockpit with uninterrupted views aft.

Special attention to lighting provides ambiance at dusk and aids vision during night passages.

Five different interior design color combinations are offered and numerous options allow you customize the boat to fit your specific needs. Folding tables turn into passage berths, extra refrigeration space and storage, optional BBQ and dive tank storage aft, washing machine, air-conditioning and more.

Incomparable

As Seahorse magazine stated in their review of the HH44, “HH Catamarans is on a mission to redefine the concept of a luxury performance multihull… from 44ft all the way up to super yacht size. Not reinventing, but defining a new type of luxury performance cat that has not, at least at 44ft, been available in this format.”

No other catamaran of this size can offer the same balance of performance and luxury.

With massive amounts of carbon fiber throughout the structure, including all load bearing areas, and the use of superior Epoxy resins, the rigidity of this yacht supersedes all competitors in this size range.

The fit and finish quality is identical to that found on our flagship HH66 yachts. Special attention to detail makes the boat safe and enjoyable without gaudy handrails, elevated solar panels or exposed storage for toys. Lighting enhances safety while underway at night and can be customized to set the mood while at anchor. Air-conditioning can be run overnight on the batteries alone.

The swing helms allow for line handling to be conducted from the safety and protection of the coach roof so you are not exposed, and two helms makes docking on either side a breeze.

We invite you to dive in and explore why the HH44 is the finest cruising catamaran in its class. This is Yachting Evolved.

“TOP 10 BEST BOATS”

“Of all the boats presented this year, none put sustainable sailing as far in the forefront as HH with its new HH44”

“BOAT OF THE YEAR” SPECIAL RECOGNITION

“The HH44 was the most sophisticated hull-deck structure in the 2024 fleet. And that didn’t go unnoticed by the judges.”

“BOAT OF THE YEAR”

“The HH44-SC elevates big catamaran sailing with an innovative package that looks and sails as well as it performs.”

Which version is for you?

HH44-OC (Ocean Cruising)

The HH44-OC is a fast, comfortable, family friendly cruiser that skews toward ease of operation for bluewater cruising. It shares the same hull and interior fit and finish quality as the sportier HH44-SC but features an aluminum mast, e-glass longeron, white gelcoat finish and mini-keels as standard instead of daggerboards.

HH44-SC (Sports Cruising)

The HH44-SC integrates the very latest in race boat technology but remains equally as comfortable as a family cruiser. This is a “no-compromise-boat” with C-shaped carbon daggerboards, a carbon rig, a painted hull finish, 4,232 watts of solar and our EcoDrive as standard equipment.

EcoDrive, an Electric/Diesel Parallel Hybrid System

The HH44 was conceived from the ground up to work with a parallel electric/diesel hybrid, an industry leading 4,232 watt solar array on the cabin top and hydro-regeneration while sailing.

Our EcoDrive provides all the benefits of an electric boat: silent fume free motoring at 7.5kts, instant torque for maneuvering, and hydro-regeneration while sailing; while also providing the reliability of trusty diesel engines as a back up.

For the technology shy, traditional standalone diesel engines with shaft drives are also offered.

“Even as the morning’s fresh breeze abated, the boat continued to perform beyond expectations… I was impressed with how well it tacked, and how well it tracked with only one daggerboard down.”

- sailing world.

Clever design for optimized liveability

The angular cabin allows the two large, forward facing windows to open fully from inside the generously sized (187 sq ft or 17.4m2) salon. ceiling height is over 2m (6’6”) high throughout. comfort underfoot has been enhanced with non-skid eva foam decking as standard..

Swing helms & pocket seats

Steer the boat from the outboard position with the wind in your hair and increased visibility of your sail plan. a fold down helm seat stows out of the way for everyday living and easily deploys when needed. rotate the helm(s) inboard and steer from the protection of the three-seat sofa on the aft beam..

Innovative Features Abound

The hh44-sc comes standard with 4,232 watts of custom integrated solar, an electric parallel hybrid with shaft drives, folding transoms, dual swing helm stations, forward opening salon windows, line tunnels, eva foam decking and carbon fiber design detailing throughout to create a truly ground breaking yacht..

Built with safety in mind

Carbon and epoxy construction creates the strongest yacht possible without adding weight. all lines run under-deck to create an uncluttered walkway. stanchions are 900mm tall to keep your loved ones safe. a continuous, unbroken toe rail runs the length of the deck with all hull and deck-joints fused and hidden..

A home away from home

Exceptional craftsmanship and industry leading fit-and-finish is evident throughout, with foam core furniture and exceptional joinery, top of the line fixtures and bosch electric appliances standard. cabinet locks are cleverly hidden in the modern design and an optional pocket tv can deploy and spin to face the viewer. movie night has never been better..

General Arrangement

Where can I see an HH44?

To learn more about future opportunities, please subscribe to our newsletter or email us at [email protected].

What size dingy will fit on the davits?

We recommend a 10-11 foot tender. A 12 foot tender can fit but will be tight. The davits are carbon fiber and have a high load capacity with a dual push button captive reel for ease of operation. We offer Highfield tenders in our price list and can ship with your boat, if requested.

Where is the HH44 built?

We have two owned and operated state-of-the-art production facilities. One in Xiamen, China and a second in Cebu, Philippines. All future HH44 and HH52 orders will be built in Cebu, which is an excellent cruising ground to start your journey, or we can facilitate delivery (by crew or ship).

How do the transoms operate?

The design is similar to sugar scoop transoms found on monohulls. After unlocking them, a single line at each helm winch will lower the transom until a shock absorber takes over and rests the 100% carbon fiber transom horizontally. Simply use the winch to raise them when done. An optional electric door will allow you to completely “close” the boat while away, or you can use the optional side pocket doors to leave the boat closed for additional safety and security.

Can I run the A/C without a Generator?

Yes, if you purchase a boat with our innovative EcoDrive, the House Bank is large enough to run the A/C overnight without the need to run a generator. In fact, there is enough power to run the A/C in the master cabin for over three days! With 4,232 watts of solar on the cabin top the batteries should also be able to charge fully on a sunny day without running the EcoDrive system to charge (subject to conditions).

How high is the bridge-deck?

The HH44 has just over 800mm (31.5”) of clearance. This is far more than you see on production cats of a similar size. Our boats are designed and built as serious world cruiser and it requires a healthy clearance to avoid wave slap or slamming. Any boat in a slamming situation is simply not comfortable and our design minimizes this even when the conditions get serious.

What is the LOA with transoms up?

The LOA can vary with this unique design. With transoms down, the vessel has a LOA of 15.15m (49.7 ft). With the transoms folded up, the LOA from davits to Bow Sprit are 14.23m (46.68 feet), easily fitting into a 15m berth.

How much does it cost and when can I get one?

We would be delighted to give you up-to-date information on pricing and availability, or to answer any other questions. Please contact us here or email us at [email protected].

Why did this boat win so many awards?

The HH44 is truly an innovative boat in a category that has historically been slow to adopt new technology. The electrification we are seeing in other industries is just now being designed into the cruising yachts of the future, and the HH44 hopes to lead by example by designing the boat around the idea of electrification (instead of trying to modify an old design). With an enormous solar array and a battery bank half the size of a standard Tesla, the HH44 can operate large electrical systems without the need for a generator. Systems like electric propulsion, full boat AC, 48v Winches and a large capacity water maker make cruising on this yacht more comfortable than the competition. If you want to sail around the world in total comfort and security, the HH44 is for you.

Hybrid Design Overview

There are two primary designs of hybrid systems available for yachts – Serial or Parallel .  After much research, we chose to use a  Parallel Hybrid model.   There are many reasons for this decision, which are explained in detail below.

We developed a solution that does not deviate from our history of never compromising crew safety and comfort for the latest market trends and newest technologies.  Our boats are designed to be dependable, redundant, and safe in extreme weather conditions and remote locations. In addition, keeping customer needs in focus as we modify our offerings is one of the reasons we are ‘The Worlds’ Best Liveaboard.’

We feel it is essential for our customers to understand how we arrived at our Hybrid offering. Here is our table of critical design considerations.

Go Back Top

There are two primary types of hybrid systems for yachts –  Serial & Parallel .  Parallel systems exist in either  External  or  Flywheel  versions.

This is an example of a Series Hybrid  system from OceanVolt.  These systems rely on a DC generator to charge the batteries and power the two electric motors which in turn power the Yanmar sail drives.

There are a number of reasons why this system was not selected by Antares:

• We will never put a sail drive on our boats
• Serial hybrid systems are less efficient than parallel systems
• OceanVolt batteries are not LiFePO4 chemistry (more on this here)

A  Flywheel Parallel system uses a traditional diesel engine, in a series with an electric motor and transmission to power either a salldrive or shaft.  This is an example of a Volvo design currently in development with Fontaine Pajot.

We did not select this type of  Parallel system for the following reasons:

• The space required is too ‘long’ in length to easily fit in the Antares GT
• If the clutch fails, the engine and motor are disabled
• This design is less efficient than the external parallel design

An  External Parallel system uses a traditional diesel engine. The motor/generator is kept out of the conventional drive chain and connects to the driveshaft after the gearbox. If stand-alone generation is needed a clutch is required to disconnect the propeller shaft.  If the clutch fails, it can be manually engaged, providing additional redundancy.

We are pleased to be partnering with Hybrid Marine for the Antares Hybrid.  Graeme (CEO) and his team have been outstanding in their support of our project.  We share similar values, and the leadership and expertise Hybrid Marine brings to Antares are over fourteen years in this marine hybrid business.  The technology is proven, easily serviced, and redundant.

• The best overall solution that meets our criteria
• 14 years of parallel hybrid experience in the marine industry
• Yanmar UK in partnership with Hybrid Marine (same engine we use on new GT)
• Member of ISHY (Implementation of Ship HYbridisation) since 2019

Another advantage of a hybrid, is the ability for the electric motor to serve a dual purpose and generate power.  As the boat is sailing, you can generate power to top up the Lithium batteries and power your onboard appliances.

For comparison, the power curves for the Hybrid Marine system we are using is very similar to the Watt & Sea 600 hydro generators.  The power curves are below.

Power Consumption Scenarios

We must answer the ultimate question, ‘ So What? ‘  How does the NEW Antares Hybrid affect daily life aboard the boat?  What do the power consumption scenarios look like, and why does this matter?

The following consumption scenarios are based on real-world numbers provided by Antares owners.  The solar generation numbers are based on a 30-day test in tropical conditions with Panasonic HIT panels aboard s/v Field Trip.  We have done our best to provide realistic numbers.  However, every boat owner is different, so the numbers will vary from owner to owner.

All appliances and cooking are assumed to be electric, with no LPG onboard.

The conservative model provides plenty of excess power regardless of the cruising season.  1,800 watts of solar power is sufficient to live comfortably, while completely independent of fossil fuels.

The 40 kWh of Victron Lithium allows for luxurious living.  This scenario has either the port or starboard aft cabin running the AC for four hours every day AND making hot water for showers and washing dishes.  This gives the owner anywhere from 1.5 – 3 weeks of luxury, without ever needing to start an engine to recharge the batteries.

Using a combination of the two models, it is possible to still run the AC periodically, heat the water, and still have a neutral carbon footprint.

Passagemaking consists of about 10% of the total time living aboard an Antares.  This 10% is when you may need to use the electric motors to leave an anchorage or marina.  When underway, averaging seven knots, the daily surplus of power (10kW – 11kW) is plenty of power to not only recharge the 40kWh of Victron Lithium but run A/C and any other devices on board.

This is a complex topic.  To put it simply, Antares will only use LiFePO4 (Lithium Iron Phosphate) batteries in our boats.  The reason is simple.  LiFePO4 is the most stable chemistry and far less prone to issues like fire.  There is a reason why Victron and Mastervolt are ONLY using this chemistry for their marine batteries.

Other battery chemistries used by electric vehicle (EV) manufacturers are more efficient and have higher energy densities.  At present, we don’t believe this technology is ready for the marine environment.  A fire in a car on land is tragic and potentially life-threatening.  A fire aboard a boat 1,000NM from land or in a remote atoll is an entirely different matter.

Sometimes, several pictures and some recent data are all that is needed to put this topic to rest.

ELECTRIC HYBRID DRIVE SYSTEM For silent ecological sailing

Windelo catamarans travel silently even when under power, thanks to their electric hybrid drive system . Enjoy the sound of the waves and wind while not disturbing the wildlife as you set sail from your dream anchorage to a new destination. With our electric catamarans , no more exhaust fumes and vibrations – sailing is now a really pleasurable clean, environmentally-friendly experience .

The Windelo catamarans are fitted with two 20kW electric motors from Bellemarine . With an electric propulsion, there’s no need to warm up the electric motor. You have full power from the moment you switch it on.

Motor: A reliable high-performance electric hybrid drive system

Electric motor with a good cruising range.

• At 6 knots, the Windelo 50 has a range of nearly 3 hours and 45 minutes and roughly 22.7nm per day with an 1120Ah battery bank.
• At 7 knots, the Windelo 50 has a range of nearly 2 hours and 17 minutes and roughly 15.47nm per day with an 1120Ah battery bank.

When the energy consumed is not compensated by renewable energies , the 18kW backup 500L diesel generator(s) start(s) up to supply the electric motors and recharge the batteries . The generator is in the aft engine bays and communicates with the Boat Management System . It starts up automatically when the batteries are low and/or when the power required is greater than the power the batteries can supply. So, the full cruising range of our catamarans on the motor is 1100 nautical miles . The generator can also be started manually by the skipper in 2 different modes:

• Cruising range mode : for example, the skipper wishes to start his generator to increase his cruising range when there is no wind.
• Recharge mode : the skipper starts his generator, which automatically switches off when the batteries are fully charged.

As part of the creation of new types of catamaran made in Occitanie, an audacious choice of ecological innovation has been selected in partnership with the Materials Center of « Mines d’Alès » (C2MA – IMT MINES ALES) (Gard, France). It’s a question of combining ecological performance in terms of minimizing the environmental footprint and structural resistance, and this, in a global approach of circular economy on all parts of the boat. To do this, and in connection with the IMT MINES ALES, Windelo has relied on the use of secondary raw materials, competitive  virgin petroleum-based materials, that fully comply with the specifications in terms of mechanical performance. This is a real first step to the development of a 2.0 fleet ships fully integrated into the challenges and ecological challenges of the 21st century.

Associated with an ecological approach of circular economy integrating a not insignificant part of competitive secondary raw materials from virgin materials, the architectural design and the resistance of materials on the new Windelo catamarans are mechanically tested in the Materials Center of « Mines d’Alès » (C2MA – IMT MINES ALES) (Gard, France) in connection with the architects and designers of the project. The design of the ship, and in particular the hulls and bows, go through a search for efficient structuring and arranging of materials composing it, combined with a mechanically optimized geometrical assembly. To this end, specific test developments, such as the study of distortion of the structure and of the panels constituating the hull of the ship, are studied by digital image correlation techniques coupled with standardized strength tests.

Founder of Catana

“The cruising program for this new boat raises the question of the antagonism between the search for performance under sail and the pleasure of navigation, and the development of pleasant living spaces. The originality of the answer is provided here in the arrangement of the cockpit bringing together the helm and maneuvers to the center of the boat and in the arrangement of living space that occupies the rear of the nacelle.

Just behind the mast the outer cockpit offers two helm stations protected from the wind and spray, a beautiful view of the sails and bows, and allows to have all the maneuvers on hand while limiting the needs to circulate on the bridge. Out of navigation, the cockpit can be more widely protected from the outside and open to the rear space.

Fully opened behind this cockpit, we have not developed two living spaces duplicating one inside the other but a single large space which is ajustable. We have focused our efforts on the geometry of the material and visual limits of this space and on the opening kinematics of the bays. Once opened, they “disappear” to transform the interior into an exterior. The generosity of these openings also allows to modulate the ventilation of this space by playing on a wide range of opening on its four sides

This work on the modularity and the disappearance of limits is found at the extreme rear of the nacelle, with an articulated platform to the davits transforming it into a floor when anchored, and in the rear cabins, whose wide turning porthole eliminates the angle between side plating and back side. The cabin space is therefore generous despite the relative narrowness of the hulls.

All these choices allow us to combine a contained hold of the nacelle, pledge control of the weight estimate, to a generous living space, with a central part given to navigation and maneuvering. The slenderness of the forward spikes, the significant free height under the platform, and the attention paid to the centering of the masses, complete the marine qualities expected for an offshore navigation program.

The other originality of the project brought by this new construction site is in the approach of “eco-design” on materials and construction. Strongly limiting the use of molds, the latter brings a greater margin of freedom in the variations and evolutions of the boats thus conceived. ”

Who could know if it is the father or the son who is the most  passionate? It doesn’t matter. The important thing  is to write an innovative project within a family culture, for today and for generations to come. Hand over the guiding light, this is Olivier Kauffmann’s will. “At first I wanted to make my own boat, for me and my family; go on trip around the world living on a  efficient and pleasant catamaran. I dreamed of a new quality of space. Today, the dream has matured, and I want to share it with the great family of sailors. »

Windelo is the desire to expose us to something new, innovative, powerful, bigger than oneself. To seek innovations on materials, techniques of industrialization and uses to impulse a new economic reality. “We want to be part of this transformation related to the respect of our environment, it is for us, essential to work in this respect of men and nature. Men are at the heart of the project with the desire to recruit and form a passionate team, surrounded by experts recognized as the best in their field.

And the innovation doesn’t stop here, because the constructive process makes it possible to envisage fast evolutions from one boat to another while remaining well priced. An ambitious and respectful project ; Welcome to the Windelo adventure.

Dans le cadre de la confection de nouveaux types de catamaran made in Occitanie, un choix audacieux d’innovation écologique a été retenu en partenariat avec le Centre des Matériaux des Mines d’Alès (C2MA – IMT MINES ALES) (Gard). Il s’agit à la fois d’allier performance écologique en termes de minimisation de l’empreinte environnementale et résistance des structures, et ce, dans une démarche globale d’économie circulaire sur l’ensemble des parties du bateau. Pour ce faire, et en lien avec l’IMT MINES ALES, Windelo a misé sur l’utilisation de matières premières secondaires, compétitives des matériaux pétrosourcés vierges, et parfaitement conformes au cahier des charges sur le plan des performances mécaniques. C’est un réel premier pas vers l’élaboration d’une flotte de navires 2.0 s’intégrant complètement dans les enjeux et défis écologiques du XXIème siècle.

Associées à une démarche écologique d’économie circulaire intégrant une part non négligeable de matières premières secondaires concurrentielles des matières vierges, l’architecture de conception et la résistance des matériaux des nouveaux catamarans de Windelo sont éprouvées par des tests mécaniques réalisés au Centre des Matériaux des Mines d’Alès (C2MA – IMT MINES ALES) (Gard) en lien avec les architectes et designers du projet. La conception du navire, et en particulier les bordées et étraves, passe par une recherche de structuration performante de l’agencement des matériaux le composant, combinée à une géométrie d’assemblage optimisée sur le plan mécanique. Pour ce faire, des développements d’essais spécifiques, comme l’étude de la déformation de la structure des panneaux constituant la coque du navire, sont étudiés par des techniques de corrélation d’image numériques couplés à des essais de résistance mécanique normalisés.

La rencontre avec Olivier et Gautier a été une agréable surprise pour moi, dès l’exposé de leur projet, j’ai vu réunis tous les ingrédients d’une réussite, l’expérience de gestion d’entreprises mais avec une modestie rassurante, le souci de former une équipe des meilleurs experts (sourire) et une réelle écoute de leurs avis. Au fil des rencontres, les discussions ont ravivé mes souvenirs de la création puis du développement de Catana. Les mêmes motivations, la même recherche de perfection, la même audace teintée de modestie que nous avions au départ du projet. Windelo est centrée sur le produit ; une ligne de catamarans performants construits avec les techniques les plus modernes. Je n’en avais pas conscience à l’époque mais je crois que le succès d’un bon bateau vient de cette passion pour la mer avec la volonté de marier confort sécurité et performance. Je retrouve ici cette passion, et aujourd’hui ce qui a fini de me conquérir c’est le souci de préservation de la nature, tant dans les matériaux choisis que dans les méthodes de production.

Le programme de grande croisière auquel se destine ce nouveau bateau pose la question de l’antagonisme entre d’une part la recherche de performances sous voiles et du plaisir de navigation, et d’autre part l’aménagement d’espaces de vie agréables et généreux. L’originalité de la réponse apportée ici réside dans la disposition du cockpit rassemblant poste de barre et manœuvres au centre du bateau et dans le traitement de l’espace de vie qui occupe l’arrière de la nacelle. Juste en arrière du mât le cockpit extérieur offre deux postes de barre protégés du vent et des embruns, une belle vue sur les voiles et sur les étraves, et permet d’avoir l’ensemble des manœuvres à portée de main tout en limitant les besoins de circuler sur le pont. Hors navigation, le cockpit peut être plus largement protégé de l’extérieur et s’ouvrir sur l’espace arrière. De plein pied en arrière de ce cockpit, nous n’avons pas aménagé deux espaces de vie dupliqués l’un à l’intérieur et l’autre à l’extérieur mais un seul grand espace dont le degré d’ouverture est très largement modulable. Nous avons porté notre effort sur la géométrie des limites matérielles et visuelles de cet espace et sur les cinématiques d’ouverture des baies. Une fois ouvertes elles « disparaissent » pour transformer l’intérieur en extérieur. La générosité des ouvrants permet également de moduler la ventilation de cet espace en jouant sur une large gamme d’ouverture sur ses quatre côtés Ce travail sur la modularité et sur la disparition des limites se retrouve à l’extrême arrière de la nacelle, avec une plateforme articulée aux bossoirs se transformant en plancher au mouillage, et dans les cabines arrières dont le large hublot tournant fait « sauter » l’angle entre bordé latéral et face arrière. L’espace de cabine est donc généreux malgré la relative étroitesse des coques. L’ensemble de ces choix nous permet de conjuguer une emprise contenue de la nacelle, gage de maîtrise du devis de poids, à un espace à vivre généreux, avec une place centrale accordée à la navigation et aux manœuvres. L’élancement des pointes avant, l’importante hauteur libre sous nacelle, et l’attention portée au centrage des masses, complètent les qualités marines attendues pour un programme de navigation hauturière. L’autre originalité du projet apportée par ce nouveau chantier se trouve dans l’approche d’« éco-conception » portant sur les matériaux et le mode constructif. Limitant fortement le recours aux moules ce dernier apporte une plus grande marge de liberté dans les déclinaisons et évolutions des bateaux ainsi conçus.

Qui sait lequel du père ou du fils est le plus passionné ? Peu importe. L’important ici est d’écrire un projet innovant au sein d’une culture familiale, pour aujourd’hui et les générations à venir. Passer le flambeau, le relais ; c’est la volonté d’Olivier Kauffmann. « Au début je voulais me faire mon propre bateau, pour ma famille et moi ; partir faire un tour du monde sur un catamaran performant et plaisant à vivre. Je rêvais à une qualité d’espace inédite. Aujourd’hui, l’envie a mûrit, et je tiens à le partager avec la grande famille des marins ».

Windelo c’est l’envie de s’exposer à quelque chose de nouveau, d’innovant, de performant, de plus grand que soi. Aller chercher des innovations sur des matériaux, des techniques d’industrialisation, des usages et impulser une nouvelle réalité économique. « Nous voulons faire partie de cette transformation liée au respect de notre environnement, c’est pour nous indispensable d’œuvrer dans ce respect des hommes et de la nature. Les hommes sont au cœur du projet avec la volonté de recruter et former une équipe de passionnés, entourés d’experts reconnus comme les meilleurs dans leur domaine ».

Et l’innovation ne s’arrête pas là, car le process constructif permet d’envisager des évolutions rapides d’un bateau à un autre tout en restant bien placé en prix. Projet ambitieux et respectueux, bienvenu(e) dans l’aventure Windelo.

Sunreef has been steadily growing its fleet of custom catamarans for the past two decades, but, evidently, it’s still got more pioneering designs up its sleeve.

Continuing Sunreef’s eco-friendly legacy, the multihull is equipped with the yard’s signature solar panels that are fully integrated into the composite bodywork, as well as the lightest batteries in the industry for cleaner, more efficient cruising. She will also be finished in a variety of responsibly sourced or recycled materials.

The Sunreef 43M and 100 Eco , meanwhile, received a new aft cockpit design. Essentially, the swim platform can be lowered and the two fold-out platforms opened up to create a vast walk-around beach club. Sunreef also shared that a contract had been signed for the 100 Eco.

The Sunreef 100 Eco sports twin 270 kW electric motors and roughly 2,600 square feet of solar panels that can generate 46 kWp. The 100-footer can cruise the seas sans emissions and harness power from the wind to increase speed.

Similarly, the 43M Eco packs two 200 kW engines and solar panels that can generate up to 50 kWp. The yard confirmed it had sold the first Sunreef 43M Eco in October at the Monaco Yacht Show. The autonomous 140-footer is set to become the world’s largest electric catamaran upon delivery.

Keep it up, Sunreef.

OUR NEW HYBRID ELECTRIC CATAMARAN

We’ve been building our dream boat “in theory” for years.  Which has never been in the form of sketches but rather a list of features that would create the most self-sufficient boat possible.  Because…

Self-Reliance + Sustainability = Freedom

Self-Reliance:  To rely on our own resources and limit our need for a marina or fuel dock.

Sustainability:  Thinking about what we do today and how it will affect next week, next year, the next decade, and so on.  It’s the recognition that we’re all part of a living system and that everything we do impacts the world around us.

In other words, we want to be out in the world living and exploring for as long as possible.  Both in terms of not having to worry about our resources or our habitat disappearing.  It’s practical, not political.

And we know we’re not the only ones seeking this kind of freedom because we have you! Our community of like-minded people we’ve been having this exact conversation with for the past decade.  It doesn’t matter if you are in an RV, Tiny House, Sailboat, Motorboat, Homestead, Farm, Ranch, or Off-Grid Island Resort…at the end of the day, we’ve all connected over our love for nature and our desire to be in it.

This new HH44 is a continuation of that conversation and desire.  This is not the ultimate, all-time perfect eco boat or zero-footprint anything.  Not even close.  It’s the best option that we could find working with viable, available solutions.  It’s the type of innovation we want to support, encourage, and see way more of.  Selfishly of course.  Because we would love nothing more than to one day announce our all-time perfect sustainable boat with living hulls made of oysters and other bivalve molluscs that naturally propel the boat as they filter feed and improve the water as we travel the world’s oceans.  It may seem preposterous now but, in my defence, prior to 1961 most people didn’t think humans would be living in outer space…so anything is possible.

But until then, here is the sexiest, most self-sufficient sub-50-foot sailing catamaran we will soon call home!

This is the beginning of a very exciting journey and because we share it with you (thank you for being a part of it) we want to hear your thoughts!  What are you most interested in as we build this boat?  What systems or features you would like us to dive into as things progress?  Is there a feature or a piece of tech you don’t see that you think we should consider?  We’re all ears and eyes!

Learn more about HH Catamarans:  hhcatamarans.com/hh44-wynns

Full Disclosure:  Transparency is important and we want you to understand our relationship with HH Catamarans, what it means and how it will affect our content.  The short answer is, that it won’t.  We did receive a small discount on the purchase of our boat in exchange for the publicity our HH44 Catamaran will inevitably receive (because we document our travels).  But we have purchased the boat and retain full creative freedom and continue to create as we always have, sharing our honest experiences.

Hello there! I honestly don’t know what to say, so I am going to tell you a bunch of random facts instead. I'm a fish eating vegetarian who hates spiders and loves snakes. I almost never took vacations growing up. I wanted to be Pippi Longstocking (still do). I misspell about every other word I write and still struggle with grammar. I love splurging on a good high tea (which is really hard to find these days). And whatever you do, don’t tell me I can’t do something, because then I'll HAVE to do it!

Comments (112)

So happy you guys are back on the water. Can’t wait to watch how the new boat performs and the places it will take you. Thanks so much for the entertainment and the hope that some day we can follow you in real life and not just on the screen.

Scott Robinson

GEL COAT !! Super stoked for you two !! HH44. Home run, you guys could not have picked a better platform for your edventures.

GEL COAT all the way. I built semi custom 90 to 100 foot yachts and to paint or gel coat was always the question. Every boat we built was gel coat for numerous reasons and all the owners always came back and thanked us for the push towards gel coat.

Look very fwd to seeing CURIOUS 2 come together.

Your next journey i think will start in Cebu, Philippines. Where it is being built. Goodluck with your new journey.

John Scaramuzzo

Congratulations and well done! I’m a monohull fan, but ai have to say that the new HH44 is the cat that could possibly sway me! The hybrid drive and solar capacity is amazing considering the boat lines are so clean and attractive! Wishing you all the best. I’m pretty sure you’re going to love it!

Matt - SV Cadence

Congrats, Jason and Nikki! The new sailboat is a dream come true! All the best.

The HH44 looks amazing! Great choice!

I’m still scratching my head to figure out how the lines magically go from the helm to the rooftop, as the saloon sides are almost all glass. 🙂

Robert Jensen

I predict the next year will find your excitement level building month by month. I do hope the folks at HH will let you do some filming of the boat during its build. RR2’s videos have been very entertaining in that regard.

Will you be sailing Curiosity in the meantime or have plans if she should sell right away?

You’ve got all of Australia, New Zealand and Queensland to explore and visiting parts of the country that are miserable in the heat of their summer are probably very comfortable as you enter their winter.

I mentioned in a post on your YT channel that selling your boat might be easier on the paperwork out of a US territory like Guam.

Congratulation you two..she looks awesome..have you thought of a name ?

Exciting times, congratulations! Looking forward to hearing all about the build and the unveiling. Will you break a bottle of champagne against the boat?

I know you guys are in New Zealand….wait I don’t really know that. Wondering what’s next while you wait for the new Cat. How long does it take to make a yacht? Ever think about starting a yachting school? Getting couples or people interested in sailing to take the plunge? Or back to the basic of sailing Wynn style videos. Good Luck Guys, Stay safe, be well!

Theresa Hislop

Wow,just watched your clip re your new dream boat(how exciting for you both!),now we are watching you tube on these beautiful catermarans,can’t wait to follow you on your next adventures and the progress of the build of curiosity2.Have a great time in South Island too,it will be cold,so wrap up🥶but it is truly beautiful 😍 Shane and Tee(we once helped Jason from having to swim to his dinghy at the Barrier😂😂😂

Jennifer Burton

Looks beautiful! Thanks for sharing all your lovely adventures!

YES! I guessed correctly! So excited for you guys.

I’m currently sailing from fort Lauderdale to Bristol RI, but I can’t wait to catch up on the videos when I get home next weekend.

Will the keel/dagger boards (?) be able to be raised in shallow water? Can the boat be made with larger foils? Can the underside be contoured with ribs or some such that can eliminate some of the wave noises under the center hull? (It could be added after the mold process, of course.)

Ron Grisoli

Nikki and Jason, Congratulations. The HH 44 OC is just gorgeous! I am so excited for you and look forward to more adventures in it. I’ve been following your sailing adventures for the past few months, and so  far, have resisted the temptation to watch them out of order. I’m on the video where you just landed in Ecuador.  However, when I saw this in my inbox, I just had to skip ahead to check it out. Awesome, sustainable technology that seems like it was made for you guys! I’m curious about the lines routed underneath the deck. How quickly could you change a sheet if one were to blow out? It certainly cleans up the deck and minimizes tripping hazards. What a beautiful yacht. Enjoy!

Daphne Church

Congrats you two! HH is a phenomenal brand and the HH/OC44 is I think their best most innovative offering yet. They are lucky to have you guys aboard as brand ambassadors. Just curious if there is actually a “business case” that can be made for the extra cost associated with the hybrid set up, or is it just the coolness/eco-friendly side of things that sold you? In one of your expense’s breakdowns, you list monthly fuel expenses on the Leopard at $86/month on average, so roughly $1k/yr. Even if you triple this amount to $3k/yr and assume zero motoring, the payback is over 25 years to pay for this option. We recently went through a similar buying decision and HH was one of our finalists, but I couldn’t make this particular feature make sense when compared to a lightweight higher performance boats this competes against with daggerboards that sips fuel at such a low clip and is a negligible portion of the budget. (Seems silly to talk about budgets when dealing with $1M boats!)

Anyway, I’d love to hear your take on this as you both are so eloquent in your story telling and your journey has definitely inspired ours. I’m assuming you’ve ordered a ZeroJet OC 350 as well to slap on the back of Clarity2, (that’s our plan) it would be great if you take delivery first and give us the full low-down! Keep up the great work and looking forward to following the new adventure.

Rupert Verwey

Hi Nikki and Jason, Rupert here from South Africa. I am so excited for you. I love the HH cats, just wish I could afford one. Heck, I cannot even afford your old Leopard cat…. :(…..maybe if I sell half my organs I might…..lol. my dream cat doesnt matter what hulls it have, I will demast it and build a solar roof from above the dingy all the way to the bow with electric drives. Kinda like the Silent 55 cat……my ultimate dream but way too expensive. So a cheapy will have to do. So I would be most interrested in the eco elrctrical system of your HH.

Jan Jenkins

Yep, Im really looking forward to you getting to know this new yacht too and sharing it with us. Very much so, only I didnt want to use that word that every man and his dog tend to (over)use beginning with EX and ending in D. Thanks to you two, I now believe cats are the pyjamas for cruisers. Gone over to the other side from the yachtsman point of view; though I still think a keelboat on a heel is a beautiful thing to behold. Not so keen on being in one anymore, but will be by your side (in the comfort of my home) in your future adventures. You really bring huge enjoyment to me whether you are having an exhilarating introduction to a new place/experience and I can empathise with the frustrations when things aren’t going right. Im sorry you cant spend more time cruising here in the North Island, the weather wasn’t the best for you this summer, but you might make it back here again! If Dan and Kiko have shown us electric motors are workable, you can show just how much more flexible you can make your routing. And maybe we will see paws on board again??

Tom Moffatt

Is CURIOSITY2 being built in Cebu, Phillipines, or in Xiamen, China? If Cebu, where is the factory? An exciting project and I am among the many that will be following along.

Thomas Chandler

Cebu — Lapu-Lapu City, Philippines

Judy Goodson

I am so excited for you both! I hope “Curiosity 1” is going to a good home. We’ve all gotten emotionally attached to her, you know. I know you’ve done your homework, so I’m sure you’re going to love your new home. Can’t wait to see her in person!

How exciting and after taking a break from current Curiosity, am sure you will maximise storage, minimise waste and only buy and use what you absolutely need. The extra storage room is just so practical, food supplies and easy access to what you need to maintain or secure your electronics – how great an option that suits you both. Look forward to having those open windows bringing in the fresh breeze but not needing endless maintenance and the open views will just make it an incredible usable space. Just curious – do you think the ceiling height is different than current? I am hoping you get to visit Phillipines during the build – or a virtual visit (hire a local videographer) to talk about the build process, features before they are hidden – as who knows you may not be upgrading and removing older items for some time yet we all seem interested in the new gear you research. I very much like the idea – not using diesel, but do turn it over, replace diesel as it does age and no longer become viable over time (night-time turn it on boost power after cloudy days). So looking forward to you personalising things even more – your coffee maker, the cups and plates, cushions, soft furnishings too.

Alan Solomon

Oh My God. I am soooo excited for you both. Congratulations on this incredible, exciting journey you both have created. Awesommmme!!!! Very excited for you both! I know nothing of boat construction, on-board instruments and machinery or sailing for that matter. I sense that there are a lot of good, informative thoughts, suggestions, and ideas in the 41 or so comments above me. You might consider checking em out, one-at-a-time. The new HH is so modern, precise, clean with minimal rounded edges it reminds me of something from another world! Alien-like! Congratulations on this great move and exciting choice. Looking forward to next Sunday and more smiles from you guys. Safe travels, Love and Joy,

Pam McClure

Jeff Parkinson

I’m so excited for you guys! Can’t wait to see you guys sailing on your new OC44! Wondering whether you chose the carbon fiber mast?

Juan Paredes

Congratulation for the selecting the right boat for your needs. Great peace of mind to know that that’s all figured out (at least on paper). Still very curious about why you did not go with an all EV/ Solar catamaran like Silent Yachts (other than money of course)? Non the less, congrats and looking forward to the delivery video and many more to come.

Jeanette Brennan

You both sound so wonderfully giddy with excitement, and rightly so! Excellent adventures ahead – enjoy all the time you spend with your families when you get there. Freedom will be yours as you hit the high seas (hopefully not too high) later on. Will her name be Curiosity 2 or will she be called Freedom? We’re all really excited to hear about your upcoming travels. Hurry back! Stay safe, healthy and happy. 💓🌊⛵️🌊🙏💓

Outstanding boat…what a beauty! Hard to wait to see the completed boat and have longer video tours of each area of the boat. Enjoy your time ashore and I eagerly await the upcoming adventures you will have. Someone mentioned in the comments that the boat is built in China…you said in the video that you are picking it up at the factory…is that correct and the plan?

Curious Minion

According to the HH website, HH44’s and 50’s are being built at the factory in Cebu, Philippines. Curious Minion

Mark Beresford

So excited for you…Curiosity 2 will be a trend leader for yachts for years to come…Will thereby any form of autonomous drive as we’re seeing in cars nowadays…Or is that still in the future for sailing yachts?

Umm, boats have had it for many years in the form of autopilot or purely mechanical self steering for navigation. Automatically reefing and trimming sails do exist but they are fiendishly expensive and would be a nightmare to maintain.

Are you keeping Minion ? I did not see a space for that. I assume it will be hanging aft.

Well they’re keeping *Curious* Minion, but not the Highfield dinghy Minion. They mentioned in the video about selling Curiosity that it’s just too difficult to try to store everything off of Curiosity until the new boat is ready. They are selling her soup to nuts to the new buyer, which is a selling point for them since they will be picking her up in NZ and sailing off from there. Curious Minion

Brian Higgs

TexasTumbleweeds would better describe your wanderings all over the world. Much better description of your helter skelter travels describing your lifestyle so make it the new name of your wandering boat !!!

I can’t wait to hear all about your trip home!!! I

I looked up the factory and I see there are several places that sell these catamarans. Where will you leave from?

I am so excited for you both! I hope that there are good years ahead with little and hopefully NO maintenance. It seems that you have been working so hard over the last few years. You need to have some fun again.

Finally, one of my favourite sailing youtube channel, owning an HH 44 eco catamaran. Looking forward to the experience and seeing how that will change the trend in sailing. Congratulation guys!

I bet you will be riding the HH45 open

Beautiful boat. How fun!!!! Can’t wait for your next adventures:):):)

Congratulations….so happy for you two.

I absolutely love C2. I have a small suggestion to push her from eco friendly to eco loving. Have you considered either a CNG (compressed natural gas) or dual CNG/diesel fuel? The advantage of having a fuel that won’t spoil and has a lower CO2 foot print. I realize you have already signed a contract and they may be a bit more expensive.

Which hull number will your boat be?

Chris Aulbach

I read that it will be hull #3.

Sorry for all the comments. I was one of those kids who was always asking questions and I’ve had 70 years of practice.

Have you looked into the wired helm controllers? I see them sometimes in the Nautistyles boat tours and Rico swears by them as they let you go up on deck during docking and are more reliable than using wireless ones.

Elizabeth Jo Collins.

Congratulations!!! WOW! I want that boat! You guys have a beautiful new boat, and I’m looking forward to seeing you aboard it soon. I do have a question about where the wash and dryer are located? I’m so excited and happy for you two. GOD Bless you and keep you smiling and sending us all updates. Many prayers and hugs to you.

I was expecting you to go with a little larger boat as you mentioned in your ‘Checklist’ video but I can see sacrificing size to get the other features you want.

Are you going to do a comparison video on Curiosity vs Curiosity 2?

I think you should add the extra solar over the dinghy. Speaking of dinghies, are you keeping the one you have now or going with something different? Solid hull ones seem to be popular. Adding a cover to protect from sun might be worth it too for the long run. Considering what happened during your eventful passage to New Zealand I’d be looking at a dinghy that is deflate proof. Also a better location for your liferaft. One where you can get at it faster and one that’s in a more secure location near the back of the boat.

I’m so happy for you guys it looks like a dream catamaran. Just one word of caution make sure H&H has cleared up any lawsuits it has with gun boat. All the designs at H&H has are stolen from American builders from the Chinese, why am I not surprised?

The son of the owner of HH looks a lot like Jason. When you go to pick up your boat don’t bring the wrong one home.

If the solar panels on the boat are custom I would see about buying a spare set as soon as you can so in case they become unavailable you’ll be covered for future repairs.

I hope SelfReliance isn’t the new name. It is so unimaginative. You can do better.

Your new catamaran looks amazing! Per your request, here are topics / questions I’d like to learn more about.

1. What color(s) did you choose for the hull?

2. What can you do now, or do differently with the new / enhanced features of this boat? (More time between provisioning, certain budget items will be more or less, etc.)

3. Suggestion: consider working with HH to create videos showing construction / build out of key areas. Could be an interesting series and benefit HH as well.

Buy a more comfortable chair for the Nav station. Maybe bug screens for those large windows when you open them. You’ll just use them at anchor in buggy locations, although they could keep out the flying fish too.

Considering your ‘Want list’ does HH have tight weather enclosures for the cockpit for those hot/cold/windy/high seas days?

Gregory Illes

I am intensely curious, perhaps you know: HOW does a 44′ catamaran get shipped from Xiamen to North Carolina? (I presume you’ll be receiving the boat in the US.)

The HH44’s are being built in Cebu, Philippines.

According to the HH website, all future HH44’s and 50’s are being built at the factory in Cebu, Philippines. And you can ship a boat or have it delivered anywhere (limited only by your willingness to write checks) but if Nikki and Jason plan to continue their circumnavigation, picking it up in the Philippines makes more sense. Based on the video, I guess we’ll all wait to find out! Stay tuned! Curious Minion

Im soooo jealous! How long is production meant to take?

July 2023 is the projected delivery date. Curious Minion

My suggestion is for the Nav station is to add a 32″ or larger, wide screen monitor that you can use for most of your sailing needs and then add either or the Mac Studios ($1999 or $3999) or a similar PC set up for video editing so you can both watch the helm and do your video editing at the same time. The power and speed of a workstation will cut down on your editing time and you’ve got the extra power on board you don’t have to skimp anymore. They’ve got the power so you both could work on it at the same time. You can network out to your laptops no matter where they are on the boat. In fact you might consider adding Cat 6 or better Ethernet during the boat build. Run them throughout the boat wherever you might want to use your laptop. Faster and better connection than wi-fi.

Add some Sonos speakers around the boat too. Hard to beat their sound quality and features.

You could easily add voice command via Alexa or Google so if there were an emergency while you were in bed you could instantly command a system to turn on or shut down. Great for turning on and off lights, tv, music, and controlling HVAC, security.

Tom Tessmer

AWESOME guys! Well…yeah that’s all I can think of…AWESOME!

Will you still have a dingy and if so where does it stow?

Jim Hawkings

I live in Nova Scotia, south shore, CANADA. Very near Halifax. I do have relatives in New Zealand. I would prefer a mig welded Cat or Trimaran.. is HH associated with any builders here in Canada. I am interested in having a livaboard as my mini-home.

I love this new name “SelfReliance” for your new boat

Where … did you got it ???? 😀

Happy sailing … Happy life !!!!

Self reliance should be every humans ultimate goal in life😁 Then we can honestly give to others without hidden agendas or personal issues!

Nikki and Jason, so glad you’ve recovered from COVID! Congratulations on your new HH Cat! I’m inspired by your commitment and leadership to helping SOLVE the climate crisis with your decision to purchase a much more eco-friendly catamaran! I look forward to seeing how the ripples you create lead to waves of positive change in the sailing world!!

Keith Lacoy

Congratulations, the new boat looks amazing! Can’t wait to see the real thing in action.

Beautiful boat…are you picking it up in the Philippines? What are you plans for the next year while you wait for this beauty to be built?

Sandra & the 2 Spaniels

Boat looks amazing! Can’t wait to see Nikki cooking in the fab new kitchen! I feel like she does about propane-uh, no! I am even hoping to get an electric cooking stove in my house, if I can get the gas lines removed. The picture tour was great, but I am waiting for the up close and real tour! Congrats!!

Does your new HH-44 have radar? If you seek yet another highly intelligent source of imput regarding this boat contact Troy at Free Range Living and solicit his advise as he is real smart and he might recommend some type of modifications or what ever !!! Best wishes from Fort Worth, Texas !!!!

S/V PORTFOLIO

Good choice of boat design and technology. All electric is not yet practical for passage making, so hybrid is currently the only environmentally friendly, motor-sail silently, practical choice. Never liked the helm stations on Cats. Too exposed. These helms are a great compromise for safety, comfort and visibility. Congrats.

Michael Magill

Congratulations on your new boat, can’t wait to tag along on your next adventures. Have a safe journet home, and we will see you when your back in the water. It will be a different sailing and it looks like it will be a great way to explore. Have a great time with your family and friends . Good Luck

Sounds like the perfect choice. I’m so happy you guys can continue this amazing adventure is real style and comfort.

Christopher Davis

Congratulations, so very awesome. Who ever bought curiosity the first probably got a the best self maintained boat ever. I can hardly wait for the new adventures

Chris Davis Clearwater County, Alberta, Canada

John Curtis

I agree on the technology question, Charles. It sounds like there are many more electronics on this new boat. What safeguards are in place to ensure the safety and continued functioning of them? Are there redundant or backups for key equipment, just in case?

Congratulations! Looking forward to to all of the progress and technical videos.

Steve and Mandy

What an amazing opportunity you have created for yourselves. New boat sounds exciting. Question, with all this performance would you be kind enough to show us how everything will be secured. Being the new need for speed water bearing beautiful people that you are.

What about “Minon”?….”Minon 2″ ??. You will still need to reach shore.

Steven Irby

Very exciting! After reading your wish list for a new boat, I was pretty sure the HH 44 would be your choice. It’s the only cat on the market that checks all the boxes…the hybrid propulsion system with shaft drive really puts it over the top! I am looking forward to following your videos as you acquire and sail it. Can’t wait to see one in person. Congratulations!

I am so excited to hear that you are moving up from the near east side. The two of you have done a fantastic job building out your current boat for sure! Now you’ll only have to set sail, major work free for a few good years. Defiantly visit the South Island. You will fine it more captivating than the north, which is saying something. Peace and safe seas.

Nikki Newman

Where is the HH Catamaran factory located? Will you be taking delivery there?

HH web site states that the build site is their Cebu, Philippines plant

IDTS, it’s in the US now.

Seems that HH44’s are being built in the Philippines

According to the HH website, all future HH44’s and 50’s will be built in their factory in Cebu, Philippines. Curious Minion

CONGRATULATIONS NIKKI & JASON!! My Husband & I have been big fans for years and want to do what you do when we grow up! Please place twin order for that gorgeous OC44 for us! LOL! Laura & Paul

Ed Thompson

How exciting! So happy for you guys. Boy, it looks like a great boat with every bell and whistle one could imagine. Right decision on the direct drive in my opinion. Absolutely astounding electrical system with huge battery storage and motor/high output generator. The cockpit and salon layout is amazing. And the workroom with the huge storage and a supplemental refrig is awesome. Can’t wait to see you guys sailing in it!

A lot of amazing technology and capability on this new boat.

But I am not crazy about the large flat bottom between the hulls – an area that will make a lot of noise and take a lot of stress in high seas.

There is also a certain amount of risk in taking on an unproven model. Because of its newness and high-tech construction and equipment, many critical repairs and repair parts won’t be readily available or DIY.

Ther is a lot to be said for the principle of KISS: keep it simple, stupid!

Mike~ The builders have already proven and built high performance yachts and catamarans since 2012. Construction methods are built for America’s Cups and know what they are doing.

Rick Tressler

I agree. You two have proven that you can do anything when it comes to repairs. However, there are always going to be “issues” with a new boat. One recommendation: When you take delivery, don’t be sailing off on a multi thousand mile trip. Stick close to home for a while until most issues are worked out. Of course you already knew that. Safe travels.

They told me this same thing when I wanted to take my RV to Alaska the first year I owned it. I feel sure they will get their feet wet before a major passing.

I have been following y’all since your trip to Alaska in your class a Bounder. My wife and I are full timers for 19 mos in our Montana 5th wheel. Congratulations to both of you. Safe passage and keep the fantastic content coming.

We look forward to watching you every Sunday night. You are simply a part of our family (the ones we like) and we could not be happier for you both. Can’t wait to continue watching your marvelous adventures!

Yes, yes. All of this is wonderful, congratulations. However, your video left out the most important feature in your selection– what color did you choose?

That’s pretty important, I agree.

Sherie and Craig Masters

Yay! We’ve been wondering and waiting the big reveal! Wow! What a great boat! Perfect for you both and can’t wait to see your journey continue on Curiosity2! Now you have us thinking about HH for our second boat. 🤔

Congrats & best of luck. Price?

Jeff Cheesman

What is the build time?? From deposit to splash.

Leland Crenshaw

I am so excited for you two! You so deserve this great new boat!

Brenda King

What a beautiful boat! Congratulations.. it will be exciting to see the build underway. The work room is fantastic and perfect use for a third cabin.

Two questions.. Will she be named Curiosity? Can you tell us more about the marine refrigeration? Capacity, models etc. I know that was a big issue on the current boat.

Best of luck with the upcoming surveys!!!

The new name is … “SelfReliance” !!!

No, the name is Curiosity 2. They said so in the message.

I’m a bit old-school, but whenever ’digital’ is mentioned, I cringe. But wow! What a boat!

But where’s the life raft that drops out in the middle of the night in rough seas on long passages???!!!!

I see the sail bags sold in a flash. Congrats! I’ve anticipated this post for weeks. I’m really looking forward to the future watching you guys.

Dr J. Stuart Latham

Hi both, the new boat sounds incredible, I wish you all the best for your continued adventures on the Oceans. The tech has always been an interest and high involvement throughout my life, along with a short 7 year career in the RN so I get the draw and freedom of the Sea.

Kind regards, Stuart (Sheffield, UK)

Duane Terry

Wow, so excited for you two. The new boat Sounds amazing. Love reading and watching your blog. Love from Oregon.

Charles Lear

Two questions:

1. Are there provisions to make the aft cockpit weather tight? 2. That is a lot of technology. How do you feel about maintaining that equipment while at sea?

I particularly wondered about number 1, as well.

Meet the Silent VisionF 82 Hybrid Powercat

• By Victor Tan
• September 15, 2022

Silent-Yachts and VisionF Yachts have collaborated to create the former’s first hybrid-powered boat: the Silent VisionF 82. It’s an aluminum catamaran with three driving modes: electric, hybrid and power. A fully electric model is also available; there are 34 solar panels atop the 82. Top speed is reportedly 13 knots.

In terms of size, the 82 is most comparable to the Silent 80 : The 82 is 6 inches longer than the 80 while surrendering about 3.5 feet in beam. According to the builder, on the 82, more space is allocated to the foredeck and its “sunken lounge area” with a table, an L-shaped settee for four to port and an overhead shade from the extended flybridge deck. There’s also space for four personal watercraft or a variety of modular-furniture arrangements.

Moving inside, there’s a 581-square-foot salon, which is nicely connected to the aft deck and its alfresco dining around a table for eight. The 82 has several layout options: two galley-up versions and a galley-down option. In the galley-down option, there is one crew cabin with a V-berth forward in each of the hulls. The 94.7-square-foot galley is aft and belowdecks in the portside hull.

Alternatively, the galley-up options have the galley either in the starboard after corner of the salon or along the entirety of the starboard side. A crew cabin is where the galley is located in the galley-down option. Owners can choose two stowage spaces forward in each hull, or stowage in the portside hull and another crew cabin in the starboard hull.

Regardless of the layout, the 82 has four staterooms for the owners and guests. The 190-square-foot master stateroom is located in the starboard hull with eight hullside windows to illuminate the space. Its en suite head has his-and-her sinks and a 21-square-foot shower. Each of the forward guest staterooms is 91 square feet, and the portside, amidships guest stateroom is nearly 97 square feet. It can double as an office for boaters who need to get in a little work before snorkeling.

The 82’s flybridge has space for lounge furniture in various arrangements, or it can be utilized as an alfresco gym for fitness buffs. Regardless of the amenities here, the flybridge will always have 145 square feet of forward-facing sun pads, and there can also be four more aft-facing sun pads on the after part of the flybridge.

Maverick 440 Hybrid

 Key Benefits of Electric Engines

Quiet & Green

More Torque

Reduced maintenance

More power for house batteries

The set-up of the Maverick 440 Hybrid is for a circumnavigation ready yacht launched on the water in Cape Town, South Africa. This yacht already includes air conditioning, water maker, solar panels, generators and other items required for a circumnavigation.  

The yacht comes equipped standard with a generous bank of lithium-iron-phosphate   batteries to provide for your everyday needs and cruising pleasure while living aboard. 

Mavericks are built in a semi-custom manner. The hulls & superstructure are production modeled and the owners specify their equipment, layout, and décor. 

In this section, we focus on the benefits and set-up of the Electric powertrain. All the other good things you would find on The Maverick 400 & 440 are also available in this model.

The Maverick 440 Hybrid is an electric motor sailing catamaran. The electric motors are powered by lithium-ion phosphate batteries. The batteries are charged through a number of sources, namely; solar power, wind generators (optional), hydro-regeneration while sailing, shore power, and diesel generator(s).

The dual electric motors operating in pure electric mode from battery power have enough energy from the batteries to perform all anchoring & mooring maneuvers. This covers 90% of your use cases when operating on motors. For off-shore motor cruising & motor-sailing, there is a backup generator.  The Maverick tracks so well through its clever hull design that it only requires one motor to run straight in most conditions off-shore providing double the range. 

Our electric powertrain with multiple charging options and GenSet power back-up, with large diesel tanks, makes for the best range of any electric 44ft production cruising catamaran in the world.

Electric Motors are sail drives with feathering propellers provided by Oceanvolt.

Maverick  Life Hybrid Layout

Saloon, galley & cockpit layout.

You can customize the layout of the galley, various cockpit layouts are available and decor is all your own choice.

Three Cabin , two heads owners yacht.

This is our most popular choice of the cabin layout.

You can customize the hull e.g. replacing the desk in the owner's hull with an additional sofa/sleeper couch or

 converting the port forepeak bunk into a pantry, and/or

A workbench with the tool storage in the companionway.

The 3-Cabin Hybrid comes with

2 x 11 kW 48V DC GetSets.  

4 Cabin layout

The four-cabin layout can accommodate 10 + 2 guests.

The forepeaks are for children. The saloon has a full queen size double bed that can be used as a day bed or for occasional guests or for watchkeeping. 

The 4-Cabin Hybrid comes with a 15kW 48V DC GetSet.

Deck Layout

The deck layout shows the extensive opening hatches and good ventilation that is standard on a Maverick.

Testimonial

Genko Ganev 

San Diego, California

"As a professional mechanical engineer, I am very particular about any construction process I am involved in, the quality of the materials and components used, all key ingredients for a high-quality product. Building a “live aboard” catamaran is twice more difficult than building a house in California. Our search for the right boat builder and the right live aboard custom-built catamaran took us over a year and I can confidently say: “We found the right one – Maverick Yachts in Cape Town, South Africa”. After two meetings with Rudi Pretorius at Maverick Yachts, we signed a contract, I quit my day job and relocated to Cape Town for six months while our catamaran was built. True custom-built catamaran, well thought out and build strong. As people say – “They don’t build them like that anymore”. We are extremely happy with our choice and the entire experience was better than expected."

Sail More Often

The ability to sail more often in both light and strong conditions is the best solution for eco-cruising. The Maverick Hybrid catamarans get going under sail in just 4 knots of wind and can tack or gybe under sail power alone in just 6 knots of wind. Maverick catamarans are engineered with high-strength, low-weight materials.

The hulls and the interior modules are foam core using Gurit® Corecell™ foam for weight-saving and durability. 

A lightweight catamaran means you sail more often and for longer with less reliance on engines.

The Maverick 400 & 440 catamarans have the shallowest draft of any fixed keel cruising catamaran in the world.

Optimal weight distribution & space-saving have been achieved with the installation of electric drive motors leading to improvements in boat handling, greater load-carrying capacity, and storage space.

Longest Range when Cruising

Maverick Yachts electric motors with the range extension system allow you to travel further on motors alone than any other  44ft electric cruising catamaran on the market today.

The total cruising range setting off with full battery bank and diesel backup for electric sail drive engines  (i.e. no sail power) is calculated at over 1’000 nautical miles. (1’850 km). This range is under calm (neutral) sea conditions at 5 knots. 

The cruising range extends further through solar charging.

Cruising range is unlimited when hydro-regeneration is combined in the right proportions with sailing. 

Extend your Range

Together with solar power and wind generation you can extend your range on engines and reduce the need for diesel.

The Maverick 440 Hybrid is fitted standard with 42kW of lithium-iron-phosphate (LiFePO4) batteries, 650 watts of solar panels, and 800-liter (220 gallons) of long-range diesel tanks.

The configuration of the system is customizable to meet owners' requirements. An additional 650 watts of solar panels can be added to the bimini bringing the total of solar power to 1300 watts, consisting of 4 x 325-watt hard panels.

An optional 2 x 400watt wind generators can be added to the system to bring the total solar & wind power generation up to 2'100 watts. With the Maverick Hybrid's ability to recharge its batteries through solar power, wind generators, hydro-generators, and plug-in at the dock there is much less need for refilling your diesel tanks, saving you time and money.

Shore Power charging is available for both 120V and 230V. 

​ Performance

Maverick Hybrid Oceanvolt electric motors instantly deliver the full torque of the engines from zero revs. With immediate torque throughout your rev range, the handling and performance of the engine power are sublime. This step-change in performance is achieved while enjoying the peace and quiet electric motors provide.

The responsiveness and power of the electric motors provide confidence during docking procedures and on the open ocean through excellent boat handling characteristics in all situations.  

The Comfort of Silence

There is nothing better than the comfort of silence when sailing. With the electric motors, you get close to this level of silence when motoring. When at anchor you can enjoy the peace and quiet for hours on board as the large battery pack is powerful enough to run all the electrical house systems.

Due to the large power of the lithium-iron-phosphate (LiFePO4) battery pack, you have a greater ability to run all electrical systems on the yacht for longer periods. The battery pack is strong enough to run your air-conditioning, water maker, dishwasher, windlass, or autopilot without the need to switch on the generator. If you are conservative with your electrical consumption your batteries will recharge only through the use of solar panels, wind generator, and hydro generator. The backup generators are set to automatically come on when required and you can enjoy more silent intervals. The diesel generators are highly insulated to run smoothly & quietly. Overall there is less vibration & noise when the diesel generator is running than traditional diesel engines. 

The Power of Lithium-Ion Batteries

The lithium-iron-phosphate (LiFePO4) battery pack is the source of the main power for all the boat systems and electric motors.  This battery pack has a broader operating range than other traditional battery packs. You can use more of the discharge of the battery and you can charge the battery pack faster. This leads to far greater utilization of your batteries, providing more available amp hours that you can use compared with lead-acid / gel batteries. When you are producing a lot of electric power from solar, wind, and hydro  generators the battery pack can absorb all this charge thereby greatly reducing the battery charge time.

The batteries have less weight, much higher amount of amp hours = higher Energy Density (Wh/kg), charge much faster, and can be discharged to deeper levels than traditional battery packs. This provides more power to all your home systems for longer. While sailing both electric motors can be set to hydro generation and this is a great way to charge your batteries while cruising with a minimum impact on boat speed. In certain conditions, while sailing at higher boat speeds, the electric motors in hydro generation mode have less resistance than folding props.

Beach your Maverick 

The Maverick 440 Hybrid sailing catamaran is designed to dry out on its own bottom.

When setting off onto the open ocean it is good to know you can always get home safe. We use only the most advanced Lithium Iron Phosphate battery technology for safe operation at 48V that is UN38.3 and IEC62281 compliant. This provides a safe and conservative system with its own BMS – battery monitoring system that prevents excessive discharge or overcharging. We have 2 x powerful diesel generators that can provide sufficient power to operate electric motors while by-passing the battery bank. The battery bank can be charged from numerous other sources other than the diesel generators. By design, there are levels of back-up and redundancy built into the systems. This is coherent to the overall design philosophy of Mavericks that is designed to be independent & reliable with dual back-up built into most of the critical boat systems and the use of the highest quality components and materials.

Less Maintenance

Electric motors require far less maintenance than diesel engines. They have far fewer moving parts. The average diesel engine has 300+ moving parts including the transmission. The electric sail drive motors have less than seven moving parts and no transmission is required. 

2 X electric motors replace the traditional diesel engines.

For charging & operating efficiencies electric motors and house systems share the same MAIN battery bank. For house loads, they draw from a 12v battery topped up by the  MAIN battery bank. 

Diesel generators run in their optimum rev range with low resistance leading to greater longevity and less maintenance. 

The elective motors do not require winterization reducing annual engine maintenance costs.

Reduced maintenance costs and savings on diesel translate to an overall cost saving over the lifetime of the yacht. This saves time and money for the private owner. For the charter business, these savings translate to greater profitability, better return on investment, more productive time, and ultimately greater customer satisfaction.

Greener Eco -Cruising

The Maverick 440 Hybrid is greener in all aspects.

The system reduces the use of fossil fuel making it cheaper to operate the boat and better for the environment.

Design process:.

The design of the Ocean Eco 60 by HENNDESIGN is shaped around a new solar and electric approach towards catamaran yachting. Different to other catamarans the technology is not an add-on but a central design feature. The most obvious feature that underlines that fact is the aggressive roof line that comes down to the hull and therefore creates a larger roof surface for solar panels.

How hybrid sailing yachts finally became a feasible option

• May 17, 2019

They’ve been a long time coming, but marine hybrid propulsion systems are finally a working reality, as Sam Fortescue reports

The Bootswerft Heinrich-built 13m Yamila uses an Oceanvolt electric motor rather than a diesel engine. Photo: Peter Minder

Every sailor is familiar with the wet cough of the diesel engine, and the acrid smell of its exhaust. For some it’s the sign that an adventure is starting, for others it is the reassurance that all is well on board the boat. The traditional engine is perhaps your boat’s most important safety feature, but its days may be numbered.

The electric sailing revolution is coming – and though adoption in the marine sector is proving much slower than in the automotive world ashore, progress is being made.

The market is still relatively small. Clear market leader Torqeedo had sales of €25m last year, most of which was in ferries and compact outboards. It also offers a range of saildrive and pod drive motors for yachts displacing from 2 to 50 tonnes, or roughly 20-60ft LOA.

But sailors have been slow on the uptake, and for one good reason: if you’re planning to cross an ocean or take on tough conditions offshore, you rely on your engine to help you outrun danger or motor through the doldrums – sometimes for days at a time.

Oceanvolt AXC series is a modular shaft drive system (10kW to 40kW) that will fit in place of a tradition diesel engine

Even with the current crop of advanced lithium-ion boat batteries , the range of an electric system is measured in tens of miles, not hundreds. So a 35ft monohull with 10kWh of lithium battery (four units weighing 96kg in total) would have a range of just 24 nautical miles at 3.8 knots, or less than 16 nautical miles at full throttle.

Taking into account the incredible wastage of combustion engines, which dissipate more energy as heat and noise than they provide in propulsion, diesel is still ten times more energy dense than batteries.

“When you look at bluewater cruisers, of course you will have a diesel,” says Torqeedo’s founder and CEO, Dr Christoph Ballin. “And it’s right that not many coastal sailors opt for pure electric.”

But that doesn’t mean that electric has no interest for cruising sailors – far from it. The more common route for ‘normal’ sailors will be to combine diesel and electric in a hybrid sailing system.

Under this model, the engine is replaced by an electric motor, hooked up to a bank of lithium batteries. This can be charged via hydrogeneration – when the speed under sail turns the propeller and puts charge back into the batteries – and solar or wind. But when extended periods under power are required a standalone DC generator, which can be installed anywhere on board, supplies the electricity.

This is the set-up recommended by Finland’s Oceanvolt, which has focused on the cruising sailing market with a range of shaft and sail drive motors from 3.7kW to 15kW (roughly 10hp to 45hp in diesel engine terms).

“In the case of the round-the-world cruiser, we recommend a hybrid system with a backup genset to support continuous drive when/if needed,” says Oceanvolt CEO Markus Mustelin. “A regenerating prop, which spins while sailing and recharges the batteries (sacrificing 0.2-0.4 of a knot, depending on the boat and conditions) makes it possible to be almost independent of the genset and use it only for backup.”

Spirit Yachts starts construction on Spirit 111 – one of the largest single-masted wooden yachts ever

Ipswich-based modern classic builders Spirit Yachts has started construction on its largest project to date, a 34m sloop, Spirit 111.…

Electric propulsion experts Torqeedo wins top award for innovative electric drive

The electric propulsion pioneer Torqeedo won the largest marine equipment prize of the year today (15 November) – for the…

This system has the advantage that the generator is only needed on longer passages, so the boat still manoeuvres silently in and out of ports and anchorages.

And a well-designed, correctly sized generator is much more efficient at turning diesel into electricity than an engine not originally designed for the job. Some sailors opt for an in-line hybrid system, like those offered by Hybrid-Marine, which bolts onto the existing diesel.

These are easier to retrofit, with many of the same characteristics as the full hybrid system, but there’s the disadvantage of still having an engine boxed away somewhere near the middle of the boat.

Electro magnetism

Until now, most business has been done through retrofitting existing yachts. But an increasing number of yacht builders are looking to include electric propulsion as original equipment. The world’s third largest boatbuilder, Hanse Yachts , is perhaps the most advanced – offering its entry-level Hanse 315 with an electric rudder-drive option.

The system takes up less space than the standard diesel, is much quieter and vibration- and emissions-free. But Hanse admits take up has been disappointing.

The technology has found more interest among lake sailors. Innovative young German brand Bente has been fitting Torqeedo motors to its successful 24ft model, originally designed for Germany’s ‘Green Lakes’.

Closer to home, dinghy specialist RS Sailing has decided to fit a retractable electric drive to its new RS21 keelboat. Already christened the ‘invisible gennaker’, the system is based on Torqeedo’s Travel 1003 outboard motor.

Bigger race boats have also been attracted by the lure of low-weight propulsion. Just look at Malizia , an IMOCA 60 being prepared for the 2020 Vendée Globe with a lightweight Torqeedo system.

“Emissions-free round the world under race conditions, while simultaneously producing your own energy, is a thoroughly inspirational concept,” said Malizia skipper Boris Herrmann.

Electric has also been successful at the luxury end of the market, where lithium-ion batteries account for a smaller share of the boat’s overall cost. A 50ft Privilege 5 catamaran and a carbon fibre Gunboat 60 have both been retrofitted with Torqeedo kit, while Oceanvolt appears on a Swan 57 and an all-carbon Agile 42.

Overview of the Torqeedo Deep Blue propulsion system installed in the Gunboat Moonwave

The Gunboat Moonwave has two 25kW Deep Blue saildrives both capable of regenerating under sail. There is still a generator on board to extend battery range offshore, but “they no longer use the generator – it’s just for emergency,” says Torqeedo’s Ballin.

Spirit Yachts is also designing electric propulsion into its Spirit 111  flagship, due for launch this summer. With four big 40kW lithium batteries aboard and a 100kW motor, the yacht will be able to operate silently for hours, although it also has 100kW of diesel generator capacity.

“The real focus is not the propulsion,” explains Spirit director Nigel Stuart, “but that everything works in harmony, from galley equipment and hot water to heating, air conditioning, hydraulics etc.” The British yard is also building a 65-footer using Oceanvolt hybrid technology and a new 44-footer that is pure electric.

With racing on one hand and high-end cruisers on the other, there is something of a gap in the middle. By Torqeedo’s own admission, the cruising sailor hasn’t been a big focus of the electric revolution, but all that is about to change. “We started a bit late with sailing,” Ballin admits, “but in the next five to eight years it will be addressed big time.”

Fully integrated electric drive system will power the new 111ft Spirit Yachts flagship

What does that really mean? Well, in the first instance, it means system integration. If that doesn’t sound revolutionary, then imagine a set-up on board where solar panels, hydrogenerators, batteries, generators and motors all worked seamlessly together to keep the yacht supplied with ample power around the clock. “That’s what people are willing to pay for: plenty of energy with heating or air-con through the night,” says Ballin.

The future of hybrid sailing

In the near future, Torqeedo is planning a new range-extending DC generator specifically for hybrid sailing boats. Its existing unit is built by WhisperPower and provides 25kW, which is too much power for boats using the pod drive system.

The genset will be designed to operate at optimum revolutions, while clever DC to DC conversion decouples the battery voltage from the charging voltage, for much greater efficiency.

With boats, just as with cars, the breakthrough that will make all the difference is around battery capacity. Until range under electric power can match that of diesel, there will be many sceptics. And that isn’t likely to happen for a decade or more, according to Ballin.

“Theoretically, they’ve tested batteries in labs that are ten times more efficient than lithium,” he explains. “And if that comes through, then gasoline is done. But we are trying to combine long-term vision with short-term mindset.”

In the meantime, the prevalent technology is based on lithium-manganese-cobalt, and a process of steady development is making this 5-8% better each year. For example, BMW has just announced its next generation i3 battery, used by Torqeedo’s Deep Blue system, will be able to hold 40kWh of power – an increase of 33% for the same size, weight and nearly the same cost.

Torqeedo Cruise 2.0 FP Pod Drive is suitable for small yachts up to 4 tonnes – a folding prop can also be fitted

The other area of development is around the propeller. Most cruising systems use a folding or feathering prop designed for diesel engines. But Torqeedo’s own research shows that the consistently high torque of an electric motor is best utilised by props with variable pitch.

And yet it is Oceanvolt that has addressed this issue specifically for electric motors with its Servo Prop system, which it claims to be 30% more efficient ahead, 100% better astern and 300% more efficient in regeneration mode.

Oceanvolt says that this prop can pump around 500W into the batteries at just 5 knots – the average pace of a 30ft monohull. At 6 knots that rises to around 800W, and at a very manageable 7 knots for a larger ocean cruiser you get 1.2kW.

“A new technology can rarely compete in price with an established one in its initial growth phase,” says Mustelin. “However, we have passed this and today electric systems are offered at a quite competitive price. When you add to that the fact the electric system is almost service free, the total cost of ownership is turning in favour of electric.”

So, you may not hear them approach, but expect to see more and more electric-powered boats on the water as the revolution continues.

A question of torque

A key part of the viability of electric propulsion rests on the notion that a smaller motor can achieve the same work as a bigger diesel. There are two elements to this. First, a diesel engine is not an efficient converter of chemical energy into thrust, creating a lot of heat and noise in the process. Second, the torque characteristics of electric are much better than diesel.

Mustelin says that Oceanvolt’s 10kW motor “easily outperforms” a 30hp diesel. “Typically, maximum boat speed will be somewhat lower (0.5kt-1.0kt) than with a comparable diesel engine, but at the same time the boat will maintain the speed better in heavy seas and headwind due to higher torque. Manoeuvrability is much better in confined marina spaces.”

That’s because combustion engines only reach peak power (and maximum torque) over a small range of speeds. Torque is a measure of turning power – at the propeller in the case of a boat.

A diesel engine develops optimum torque between 1,800-2,000rpm, while electric motors deliver it from 0 to around 2,000rpm. This allows electric motors to use higher efficiency propellers that are slimmer and more steeply pitched.

Engine-driven: The ‘alternator on steroids’

It has taken years of development and over $10m of funding, but renowned boat systems expert Nigel Calder has helped design an alternator so powerful that it eliminates the need for a generator on board.

Mounted on the engine, on the second alternator position, the Integrel can produce five to ten times more power. Sitting behind the system is at least 10kWh of lead acid batteries (lithium is also an option), and Victron chargers and inverters.

“If you crank the engine it’ll charge the batteries; if you’re running with the engine in neutral, it’ll know it’s in standalone generator mode and switch to that algorithm,” explains Calder. “It will likely be cheaper than a generator installation, and eliminates the issue of the through-hulls, the cooling circuits, the long running hours, the maintenance.”

The system allows you to run all sorts of creature comforts on board that would normally require a generator: from hot water on-demand to coffee makers and freezers. “We honestly believe that this system is going to supplant generators on almost all boats that currently have, or would like to have, a generator,” adds Calder.

With the engine in gear and at low revs, tests show how the Integrel can produce some 2kW of power without increasing fuel consumption or reducing speed – simply utilising the engine’s wasted capacity. This means it will work with the yacht’s existing engine – no need to overspec – and it has already been successfully installed on a new Southerly 480, a Malo 46 and a similar-sized Hallberg-Rassy.

Case study: Dufour 382 Alcyone

Built by Dufour in 2016, Alcyone was immediately retrofitted professionally with Oceanvolt’s SD15 saildrive motor, supplied by a 14kWh lithium battery bank. Owners Michael Melling and Diana Kolpak also specced an 8kWh DC generator for range extension. The fit out cost €30,600 for the motor and battery system, plus an additional €13,744 for the generator, and installation costs were around €8,000.

They charter the boat out near Vancouver, for exploring Desolation Sound and the surrounding area where silent, clean propulsion is a selling point. “Nothing spoils the joy of sailing – or a secluded anchorage – more than the noise and smell of diesel engines,” they explained. “Installing an Oceanvolt system in our new boat has freed us from that. It’s the way of the future.”

Charter manager Merion Martin said the conversion has also been popular with charter customers, adding: “The main advantage of the system is that it consistently uses around 40% less fuel than a standard diesel engine over the course of a week’s charter. But understanding the power management system takes a bit of getting used to, and the many components involved in the system can make troubleshooting a challenge.”

50' 2022 Nova Luxe Elite 50 Hybrid

Nova Luxe, the leader in power catamaran electric re-fits, brings you ELITE 50 (IE) model as an electric hybrid new build. IE or Inboard Electric is founded on an industry proven power design. This is our Blue Water hybrid model which places a traditional Diesel Motor in the port hull and an electric motor in the starboard hull. No generator is necessary for this configuration and its top speed is comparable to a full diesel version. Unlike a full diesel, this yacht can cruise silently as electric all day. We optimize the props for different speed ranges making this the most efficient and highest performing electric hybrid of its class. 

The two propulsion systems can function independently. A redundancy level necessary for blue water. The alternator of our diesel engine is upgraded by Integrel Solutions to allow for 15kW of power (1kw is normal alternator output) to flow through and charge the batteries whenever it is running. At rest, the solar array is large enough to cover the entire house load and send excess power to the high voltage batteries for propulsion.

The 10kW solar array provides ample power to run the house load for a 24 hour period. Freedom from a generator while at anchor. In practical use, you could spend several days at an island, then use the power you stored to travel an additional 10-40 miles to the next island. Leave the diesel in the tank and travel on green energy. 

With the Torqeedo electric propulsions system the yacht has a two year warranty on all electric systems as well as, battery capacity warrantied for 8 years.

The world today is different and will continue to change. To see natural beauty you need to travel off the beaten path. When you find the oasis you have been searching for, cruise in silently, observe the wildlife and leave without a footprint of diesel, oil, or CO2.

The ocean and its? reefs all around the world are under stress. This underwater world is a true wonder. Now is the time to see it and we have the ability to do so without polluting. With your help we can transition to a cleaner planet.

A 28-metre catamaran with limitless space and comfort. A remarkable combination of hybrid technology and solar energy.

Future proof design.

WiderCat 92 has no limits. It breaks down technological boundaries and the barriers between outdoor and indoor spaces, reflecting a design concept where aesthetics, functionality, elegance and innovation coexist.

Propulsion System

WIDERCAT 92 incorporates Wider’s serial hybrid system which, on a smaller scale and just as efficiently, builds on the shipyard’s extensive technical know-how in the Superyacht division. Only Permanent Magnet technology electric motors are connected to the thrusters, each providing 583kW maximum power, while energy is produced by two 390kW variable speed generators each one with twin FPT combustion engines. Energy is stored in 30 LiFePO4 (Lithium Iron Phosphate) chemistry batteries managed by a state-of-the-art Battery Management System that constantly monitors operating parameters. The entire propulsion system ensures a cruising speed of 12 knots, reaching 15 knots thanks to the Electric Boost. In saving cruising mode, the speed is 8 knots with a range of over 1600 nautical miles. And at 6-knot speed, it can reach up to 2,400 nautical miles thanks to the Wider Serial Hybrid System. The catamaran also includes ZEM – Zero Emission Mode. Here, Wider technology lets you travel about 27 nautical miles at 6 knots in complete silence or provides 12-hour autonomy on battery power alone, without charge, when sitting at anchor. During bright, sunlit days, the 170 m2 of solar panels installed on WIDERCAT 92 will deliver energy self-sufficiency at anchor. That’s because any unused energy is stored in the batteries and used during the night. + ZEM – Zero emission mode available + State-of-the-art Battery Management System + Low noise and vibrations + Best power/consuption rate + 170 sqm of solar panels

The Wider Beach Club

The standard below deck layout offers two platforms opening directly onto the 67 sqm beach club with direct access from the VIP cabins, a testament to Wider’s indisputable know-how in terms of versatility and sea accessibility for every guest. + Drop-down side platforms open out at water level + 67 sqm Beach Club

Cabins and living areas

The standard below deck layout provides two ultra-generous VIP cabins that uniquely offer two platforms opening directly onto the beach club. In addition, there is an en-suite double Guest cabin. The lower deck also provides a generous and usable crew area at the bow. Naturally, the shipyard gives owners the option of a 4-cabin layout lower-deck. The main deck covers an area of more than 100 m2 and nearly half of it is the master stateroom alone, with a breadth comparable to a wide body. Large windows, full contact with the sea, versatility and privacy are just a few of the main features. The aft main deck offers a stunning 360-degree view thanks to the uninterrupted windows and flush doors surrounding the guests. The upper deck includes another forward cockpit that the owner is free to customize by incorporating a dinette/lounge and a Jacuzzi. The helm is also housed in the upper deck and, unlike other boats of equal length and category.

Entertainment

WIDERCAT 92 has a 67 m2 beach club that can be accessed directly from the VIP cabins, space for water toys in the bulwarks, and an 18 m2 garage that opens with an electro-hydraulic system. The garage is closed at the stern, for safe cruising even in rough sea conditions. It easily accommodates a 5.5-metre tender or a 4.5-metre tender and a Jet Ski. + 5.5 m tender (or 4.5 m tender + 1 Jet Ski) + Stowage space for water toys

Anchoring without an anchor

Equipped with Dynamic Positioning, WiderCat 92 uses an electronic satellite-controlled system to automatically maintain its position and heading. The WiderCat 92 electronic anchor system heralds a new era of environmental consciousness, sitting at anchor in Zero Emission Mode and preserving marine ecosystems.​

A hybrid powered catamaran trawler

The Island Pilot DSe (diesel solar electric) 12M Hybrid is a comfortable, moderate speed, cruising power catamaran. This vessel is equipped with a unique hybrid power system that provides a number of advantages when underway and makes it possible to live “on the hook,” enjoying all the boat’s many comforts and conveniences, for days, weeks, or longer without consuming any hydrocarbon fuel.

The power system is comprised of two 75-hp Steyr hybrid-power diesel engines, a 28-panel, 6-kW photovoltaic array (PV), two 48-volt battery banks, two 3.5-kW DC/AC inverters and two shore power operated battery chargers. The IP DSe earns the right to be called a hybrid powered boat from its ability to power the props directly from the diesel engines or using the 7-kW brushless DC motors/5-kW permanent magnet alternators that are built into each engine’s transmission (marine gear). Electrical energy for the motors can be obtained from the PV array, the battery banks or a combination of both sources. Although the boat’s propulsion system fully qualifies as a hybrid, it does not have the ability to recover energy from its motion like a hybrid car, as there is no brake pedal!

The advertising banner for the DSe that was displayed at the October 2008 Fort Lauderdale Boat Show proclaimed, “The First Six Knots Are Free,” a particularly attractive claim with today’s still expensive fuel prices. The claim is supported by the boat’s ability to cruise at up to 6 knots under ideal conditions in smooth water, using only the electrical energy supplied from the PV (solar cell) panels that cover the top of the boat’s deckhouse and pilothouse. The boat can also run for about two hours using electrical energy stored in the boat’s twin, 48-volt battery banks.

The method used to generate electrical power for the DSe is quite different from the conventional, synchronous alternator genset system used on most boats. The permanent magnet alternators that are part of the Steyr engines deliver wild (varying) frequency, varying voltage and AC current. The energy from the alternators is managed by a power-conditioning module that supplies power to charge the 48-volt battery banks. The power-conditioning module also provides the electrical energy used to operate the alternators as brushless DC motors when they are driving the propellers. The boat’s AC power needs are supplied from two 3.5-kW, DC/AC inverters.

When operating in the electrical prop drive mode the permanent magnet alternators function as brushless DC motors. The speed of the motor is determined by the frequency of the AC power supplied by the electronic power control module. The direct current required to power the motor control module can be obtained from the PV system, a battery bank, or from the other engine via its alternator and battery bank.

To sort things out: each prop can be powered from its diesel engine while at the same time each engine’s alternator is delivering energy to its battery bank. Both props can be electrically powered using energy from the PV array, or from their respective battery banks. One prop can be diesel powered while the other prop is powered electrically using energy from its battery bank, or with electrical energy from the operating engine’s alternator/battery bank.

We saw a demonstration of the worth of this cross-feed power source capability when running the boat from the Coral Reef Yacht Club in Coral Gables, Fla., to Port Everglades where the boat was to be displayed at the Fort Lauderdale Yacht Club. As we proceeded north, just offshore in the Atlantic, the port engine began to lose speed due to a clogged primary fuel fiter. Reuben Trane, president of Island Pilot, was at the helm and in a few seconds he shut down the port engine and switched its propeller to electric power drive mode. The starboard engine’s alternator provided electrical power to the port prop while the engine continued to drive its propeller. The cross-feed power option also creates an opportunity to reduce fuel consumption and engine wear/maintenance when cruising at the moderate speeds many of us prefer.

The boat’s propulsion system is managed through a Tecnautic steer-by-wire, power-by-wire helm control. Everything is transparent, movement of the power levers has the identical effect regardless of whether a prop is being turned directly by an engine, or electric motor. The Tecnautic system integrates the boat’s autopilot controls.

Powering the props electrically improves handling of the DSe by providing very high torque at even the lowest possible prop speed (a characteristic of almost all electrical motors). There is immediate response to movements of the power levers. When used in planning hull sport boats the same Steyr diesel-electric engines can operate in an electric-boost mode in which power from the electric motors is used to increase the torque available from the diesel engine, reducing the time required for the boat to get on-plane.

The boat’s accommodations are on three levels, the uppermost, the bridge (we think more accurately called a pilothouse — it’s heated and airconditioned), the deckhouse and within the twin hulls. The pilothouse provides 360° visibility from the twin helm chairs. Seating for guests is provided at a slightly lower height, providing excellent visibility without interfering with the sightline of those at the helm. The seating extends around the sides and aft bulkhead of the pilothouse, with reconfigurable tables to hold the refreshments. Ports and doors provide access to the side decks. The helm station has a Garmin chartplotter at the center, plus a pair of unobtrusive engine monitor panels. Unlike some helm designs, there is no attempt to overwhelm the helmsman with a vast array of rarely used and generally uninformative gauges. The Tecnautic power-by-wire, steer-by-wire and autopilot control is immediately at hand. Based on our experience with the Tecnautic pilot on our boat, steer-by-wire will be the preferred operating method.

The large deckhouse provides the primary accommodation. It is entered via a companionway from the port side of the pilothouse. The galley is aft on the starboard side with the dining and seating area occupying the full width of the deckhouse. The master stateroom, with a centered queen size bed is all the way forward and arranged so that, if you wish, you can lie in bed with your head on the pillows watching the passing scene. The forward master stateroom can be isolated from the remainder of the accommodation with a sliding partition set into the bulkhead.

The guest stateroom is all the way aft, providing excellent and highly valued separation when two couples are on a cruise. The two heads, dressing rooms, storage space, washer/dryer and engine enclosures are in the two hulls, at a level below the deckhouse. The facilities for the master stateroom are in the starboard hull. Those for the guest stateroom and the passage to that space from the main saloon are in the port hull. Being able to get away from others without leaving a boat is a valuable commodity. Overall, we think this to be a very workable arrangement.

The forward deck ahead of the deckhouse provides adequate room for a few deck chairs and a table to hold your wine glass. The catamaran design provides a fine platform when at anchor, resisting the annoying rolling that too often occurs when you are anchored in a quiet cove and someone passes and throws a wake.

The company’s website, www.dsehybid.com contains a great deal of information and videos of the boat’s interior.

The DSe is different; different from most power catamarans and surely different from a monohull trawler such as the Island Pilot 435. With its ability to operate for extended periods of time without consuming fuel and its excellent ability to ignore the wakes of passing boats, it provides an intriguing way to spend long periods afloat.

Deep Blue Hybrid

Deep blue is a fully integrated propulsion and energy management system, industrially engineered and customizable with modular components. the result is exceptional performance, compliance with international safety standards, and highly intuitive operability.

• Relaxation: no noise from the motor and only a little noise from the generator
• Environmental protection: use renewable forms of energy
• Independence: adequate energy on board, less need to head for a marina
• Convenience: simple joystick docking
• Simplicity: only one type of fuel – and less of it required

System Overview of the Hybrid Drive System

System Components

High-capacity lithium battery technology.

Lithium-based batteries are the technology of choice for electric mobility applications. They store significantly more energy than all other batteries, they maintain a high current, they do not lose their charging capacity, they supply power reliably, and have no memory effect. They also have a much longer useful life than lead-based batteries.

The benefits for customers:

• High energy density

• Lower costs

• Long service life

• Highest quality and safety standards

• AC on-board power supply for galley, air conditioning, water maker and other electrical consumers on board (hotel loads)

• Low-voltage DC power for lighting, radio, navigation, winches, etc.

Always in control

Deep Blue Hybrid offers intuitive operation presented on the multifunctional display, providing a complete overview of the entire system and access to all control functions.

The software keeps an eye on everything and prevents errors like deep-discharging batteries. An easy-to-understand graphical user interface is available as either multihull or monohull and delivers complete, up-tothe- minute system visualisation.

Premium throttles

We’ve come to expect an intuitive way to operate our technical devices. We expect detailed information, nicely displayed and clearly arranged. We expect that the objects we use are both beautiful and functional.

This is what spurred us to create the new Torqeedo throttle family and improved user interface for Deep Blue.

Our premium throttles offer the right solution for every application, whether for sailboats or on motorboats – ergonomic, strong and functional. All premium throttles come with Bluetooth built in for simple integration of Torqeedo’s TorqTrac smartphone app.

Hybrid Drive System and Integrated Energy Management

Hybrid drive system.

Powerful and silent electric drive systems allow manoeuvring and sailing at hull speed.

High-performance batteries adapted from the automotive industry enable prolonged motor-cruising for up to 50+ nautical miles without use of a generator. Solar power generated on board and hydro-generated energy – the propeller rotates while boat is under sail – provide additional propulsion. Besides, the integrated generator provides sufficient energy to cover long distances, if required.

The slowly rotating electric drives allow precise maneuvering and in combination with joystick docking makes putting out to sea and berthing as easy as pie.

Integrated energy management

The integrated management system of Deep Blue Hybrid makes it possible to use available power in any way you wish – for the powerful high-voltage drive system, for the 24 V on-board power supply or to operate equipment with 230 V AC current. Deep Blue Hybrid is designed in such a way that energy is always available where it's needed.

The combination of energy generated from renewable sources and by the generator means that there is always sufficient power available. However, the generator does not need to run for as long.

Clean and safe electricity can be used for all equipment and so it is no longer necessary to have propane or petrol on board. A tender can also be run electrically and can be charged from the Deep Blue Hybrid on-board power system.

Professional Safety

Professional safety for your sailing yacht.

Particular attention should be paid to standards compliance and safety during the development of a hybrid drive system. During the years spent on developing the Deep Blue Hybrid system we followed safety concepts that, for example, are standard in the automotive industry – but which previously could not be found in powerful electric drive systems for electric sailing yachts.

In addition, electrical drive systems for electric sailing yachts pose special challenges that are not relevant for other industries. In this respect, it is not enough to just follow the standard of other industries for high-voltage boat drives. As we are used to setting new standards, we have done so with regard to safety. Below you will find a number of examples of the Deep Blue Hybrid's unique safety concept.

Isolation monitor: constantly monitors that the voltage from all 360 V components is completely isolated from the boat – not just for individual system components but for all of them. If damage is detected, e.g. to the cable insulation, the system will issue an alert. In the event of dangerous insulation failure, the system will be shut down.

All components are waterproof: Components that were not specifically developed for boats are not always waterproof. All the components of a high-power system on a boat must be waterproof to guarantee safe operation. That is why all of our components are waterproofed.

Automotive industry-level battery safety: The first lithium batteries for the marine industry with the advanced quality standards of the automotive sector are the result of Torqeedo's collaboration with established battery manufacturers. Integrating a battery into a drive system and the associated safety concept alone requires considerable effort that can only be achieved by working together with the battery manufacturer.

Battery venting: In the unlikely event that the redundant safety mechanisms of the battery fail, the battery cells can reduce their temperature and pressure via a pressure valve. While batteries are installed in electric cars in such a way that they can discharge battery gases directly onto the road, on electric boats the gases must be channelled safely off the vessel. We developed the first safe venting system for boats for the Deep Blue System.

Battery damping: All components on fast and seagoing boats are subject to constant high levels of shock that exceed shock levels on the road – in some cases over 12 g of acceleration force. The same holds true when trailering the boat. Since batteries and battery electronics are not designed for these constant impacts, they need their own damping system on boats (in addition to the damping mechanisms within the battery). Torqeedo is the only company in the world that provides this for maritime use.

Benefits for Boatbuilders

Custom-built solutions are often pursued in order to meet a user's requirements. These individual hybrid projects raise a number of difficulties:

• High-end components do not exist for the custom project. High-tech safe lithium batteries, for example, require an intensive design-in process in close cooperation with the battery manufacturer's research and development department. However, reputable high-voltage battery manufacturers do not supply their batteries for custom solutions that they are not familiar with and that have not been coordinated with them in detail.
• Creating an integrated hybrid system requires a comprehensive research and development project accompanied by many person-years in the field of development running to the tune of several million euros. These efforts are not undertaken for custom projects, leading to lower reliability and a lack of complex but important safety features (such as pilot lines).
• The system integrator has the statutory duty to ensure that the hybrid system complies with all the relevant and mandatory standards such as the Machinery Directive and the EMC Directive. Custom hybrid systems do not generally meet these standards. Since a boatbuilder is responsible for ensuring that the entire boat complies with standards, the installation of custom-built hybrid systems constitutes a serious risk for boatbuilders.

Unlike custom-built hybrid systems, DEEP BLUE HYBRID addresses the requirements of environmentally aware customers, offering a turnkey solution that guarantees compliance with the relevant norms and standards.

• DEEP BLUE HYBRID was created in an extensive research and development project involving a large number of mechanical and electrical engineers over several years. The components were carefully selected and coordinated with an overall system. Essential inspections and certifications were performed at system level.
• High-end components such as hybrid batteries from the automotive industry were integrated into the system.
• Torqeedo assumes responsibility for the functionality and compliance with relevant standards for the whole system.
• DEEP BLUE HYBRID was developed on the basis of modular components. It allows flexibility and scalability without affecting system integration and reliability.
• DEEP BLUE HYBRID for electric ferrys, electric sailing yachts, electric catamarans & electric water taxis.

Power catamarans Solar - Electric - Diesel - Foil ...

Eco – traditional diesel engines or smart hybrid.

eSolar – 100% Green

Foil – Pass the 30kts limit

ECO – Simple & Reliable

2 Diesel engines from 80 to 140hp. Diesel engine is mostly used on power catamarans with proven reliability. Possibility to combine both electric and diesel engine on Smart Hybrid solution.

A complete system with 2 electric engines, strong solar panel area at 13kW and a 90kWh lithium battery park. It is clear you will need Diesel DC 48V generator to be realistic with cruising.

This version is today based on Diesel engines but soon we will propose Electric solutions. You may request your target speed and therefore size engines.

Only 13T light Displacement …

The key point with Power catamaran and especially electric configuration is Weight. With 13T light and 16T ready to cruise with many options, you clearly have one of the lightest 63ft Power Catamaran. We need very few kW energy to achieve -30% of hull speed (13.5kt). Cruising 9kts with 1L/Mile coming either from Diesel to propeller or Diesel to DC generator is already achieved.

Compared with 30T light displacement catamarans you need 35% to 80% less energy (kW) for same speed.

Use Solar to Power …

Solar version has electric engine(s) and massively use Solar panels to load Lithium park energy. This energy is stored to be used when needed. As real, if you intend to use ONLY SOLAR energy to power the Class 6 without using lithium park ; you need to target max 6.5kts with beautiful sunny day from 11h AM to 3h PM. Then you will use lithium park energy or Diesel DC 48V generator.

Use Kite to Power …

You have many Kite solutions to chose from. They can be super easy to launch/get back such as LibertyKite. You expect 5kts speed with 20kts wind with the small 20m2 kite. A 40m2 kite will be tested soon. Other brand and solutions are available but expensive and more complexe … to be tested. View video Class 6 with Kite

Flybridge option

Class 6 Power is configured with optional Flybridge. That is a custom area with different layout solutions. Final design upon your requirements.

Foil versions

Class 6 Power Foil is made to go really fast (over 30kts) . Two options : First one with normal Diesel engines and conventional shafts. The purpose is to give lift with foils and save fuel. Second one with electric engines and special foils stern to completely FLY and pass the 30kts.
