What Is A Catamaran Sailboat? (And What It Looks Like)

What Is A Catamaran Boat? (And What It Looks Like) | Life of Sailing

Catamarans are increasingly popular for sailing and commercial use, but what sets them apart from monohulls and other multihulls?

A catamaran is a twin-hull boat with two equally-sized hulls placed side by side. They’re powered by engines, sails, or both—and they’re known for efficiency and speed. Catamarans are the most common kind of multihull boat.

In this article, we’ll go over the characteristics of catamarans and how to differentiate them from other types of boats. Additionally, we’ll cover the advantages and disadvantages of catamarans and compare them to trimarans and monohulls. We’ll also go over the most common types of catamarans and their uses.

We sourced the information in this article from marine design guides, boat identification resources, and the online boating community.

Table of contents

‍ How to Spot a Catamaran

Spotting a catamaran is easy. Simply look at the hulls and count them. Catamarans have two hulls side by side and a relatively large gap between them where you can see light on the other end. Catamarans are distinct from trimarans, which have an additional hull between the two outer hulls.

How do Catamarans Work?

The principle behind the catamaran is simple. You can think of catamarans like cars and monohulls like motorcycles. Catamarans distribute their weight between hulls on either side, whereas monohulls utilize only one hull.

Evidently, cars are much more difficult to tip over and can hold much more weight. Additionally, cars are wider, as they have much more contact with the road. Catamarans work in a similar way, as they have a wide stance and contact with the surface on both sides.

Obviously, that isn’t the most precise comparison. But the basic principle is the same, and catamarans have a few notable benefits over monohulls.

Catamaran Vs Monohull

Catamarans are easy to distinguish from monohulls. A monohull is just a regular old boat with a single hull. The vast majority of boats and ships are monohulls. Catamarans have two hulls, which are usually sleek and narrow.

Here are some comparisons of catamarans and monohulls, along with the advantages twin-hull designs have over most single hull types.

Benefits of Catamarans

Catamarans have numerous benefits. The first is speed. Catamarans produce less drag than monohulls and thus can achieve excessive speeds both under sail and power. They don’t need to plane like monohulls to achieve these high speeds, and they use less fuel.

Catamarans are also much more stable than monohulls. They have a wide stance and shallow draft, and many waves and swells can travel between the hulls instead of below them. This effectively reduces an entire axis of movement and prevents catamarans from rolling excessively.

Drawbacks of Catamarans

Catamarans aren’t advantageous in every way, or else we wouldn’t bother building monohulls. The disadvantages of catamarans limit their use to niche commercial applications and high-end yachts. But what are the drawbacks of a twin-hull design?

Sailing catamarans don’t follow many of the traditional boat handling rules and characteristics that sailors pass down for generations. Some, such as hull speed limitations, are good to do away with—while others, such as responsiveness, are not.

Catamarans aren’t as quick to the helm or responsive as monohulls. There are some exceptions to this rule, but for the most part, you’ll get a lot more feedback from a single-hull vessel. Additionally, the large section of deck between the hulls of a catamaran is prone to pounding in rough seas, which is loud and uncomfortable.

Catamarans can sometimes be twice the width of an equivalent monohull sailboat, which can increase mooring fees and limit docking options.

The final major drawback of catamarans is a consequence of their stability. Traditional full-keel monohull sailboats have a very low center of gravity, which makes them roll in heavy seas but ensures a recovery.

Catamarans have a higher center of gravity, and they can’t right themselves after a knockdown. And though catamarans are less likely to roll, a severe list on a multihull is a much more serious concern than on a ballasted monohull.

Catamaran Vs Trimaran

Catamarans and trimarans are often lumped together, but they have very different design and performance specifications. Trimarans have three hulls, whereas catamarans have two.

Trimarans look a lot like catamarans from the side, but a quick glance at the bow or stern can set them apart. Trimarans are faster than catamarans, as they distribute their weight across three hulls instead of two. This helps them stay centered and reduces interference from pitching and rolling.

Catamarans are fast, but they lose out to trimarans when going head to head. However, catamarans are much less expensive to build and maintain and often have roomier cabins due to their larger hulls.

Types of Catamarans

There are numerous types of catamarans, and their uses vary widely. The catamaran is one of the oldest and most useful hull types, and some variants have been used for thousands of years. Here are the most common kinds of catamaran boats and their uses.

Sailing Catamaran

Sailing catamarans are probably what you think of when you hear the name. Sailing catamarans are sailboats with two identical hulls connected by a center deck. The largest sailing catamarans are spacious and stable vessels that are capable of serious offshore sailing.

Sailing catamarans have a number of notable advantages over monohulls. Monohulls, which are traditional sailboats with a single hull, are limited by a simple concept called hull speed. As the bow and stern wave of a monohull intersect, they cause drag which limits the top speed of the boat.

Catamarans are not bound by hull speed limitations, as they have two hulls. Catamarans can go twice or even three times as fast as similar monohulls and achieve excellent travel times.

Catamarans are also more stable than monohulls, as their wide stance and shallow draft reduce the effect of rough water. They don’t heel, as the force of the wind is counteracted by the double hulls. Additionally, modern sailing catamarans can ‘wave pierce’ by cutting through swells instead of riding over them.

Sailing catamarans come in many shapes and sizes. Small sailing catamarans, such as those used in races and regattas, are known for their speed and relative stability compared to light racing monohulls. Sometimes, they feature a smaller second hull for stability—these are called outriggers.

Sailing catamarans have spacious interiors thanks to the large cockpit between the hulls. This cockpit usually contains cooking and eating spaces, a place to sit, and a hallway between the hulls. The hulls usually contain living quarters and often mirror each other.

Power Catamarans

Power catamarans have an even greater variety than sailing catamarans. These vessels are used for everything from party platforms to ferries and patrol boats.

Power catamarans are a recent development, as engineers and marine architects now realize they have numerous hydrodynamic advantages over other hull types.

Catamarans are much more efficient than other hull types, as they have less drag relative to their size. Additionally, you can build a much larger catamaran with less material. This makes them popular for car and rail ferries, as builders can construct a very wide vessel with two small hulls rather than a narrower vessel with a large single hull.

Military and Commercial Catamarans

Even the military has found a use for the catamaran hull shape. The Spearhead class EPF is an expeditionary fast transport vessel designed for carrying capacity and speed. It has two sharp hulls and a huge cargo capacity.

The Spearhead class EPF is 337 feet long, which is about the same length as a WW2 escort destroyer. Yet despite having a similar length and displacement, these catamarans can travel more than twice as fast—43 knots, or nearly 50 miles per hour. Their great speed is a direct consequence of their catamaran hull type.

Power catamarans are also used as patrol and utility boats on a much smaller scale, with either outboard or inboard motors. The State of Texas uses catamarans to patrol shallow rivers and lakes. Texas Game Wardens utilize state-of-the-art aluminum catamaran patrol boats, which are fast enough to outrun most fishing boats.

There’s another form of power catamaran that you may not have considered. Pontoon boats are technically catamarans, and they’re enormously popular on lakes and rivers throughout the country. Pontoon boats aren’t known for speed, but they’re a great platform for a fun and comfortable outing.

Catamaran Houseboats

The final common type of power catamaran is the two-hulled houseboat. Houseboats don’t always use the catamaran hull type, but it’s common enough that most major manufacturers offer it as an option.

Catamaran houseboats have a few notable advantages over monohull designs. For one, they’re easier to build—especially when pontoons are chosen. Additionally, they’re better suited for navigating shallow water. These vessels can support more weight across their two hulls, offer increased stability, and they’re also efficient.

Why Aren’t Catamarans More Common?

With all the advantages listed in this article to consider, it may seem strange that the use of catamarans is still somewhat limited. At the end of the day, it comes down to economics—as monohull boats and ships are simply cheaper to build.

Additionally, catamarans have some distinct limitations. Monohulls have lots of storage space in their hulls and can carry thousands of tons of cargo safely in all weather conditions. Catamarans lack this space and low center of gravity, so they’re not ideal for transporting cargo past a certain point.

Additionally, monohulls work, and many people are reluctant to experiment with new designs when old designs work just fine. This rule applies to both large and small boats.

A large monohull sailboat can be constructed at low cost from stock plans and reliably sail almost anywhere. Very little complex structural engineering is involved, and looser tolerances reduce cost and maintenance requirements.

What Is A Catamaran? Does It Have Engines Or Can It Only Sail?

definition of catamaran boats

Catamarans are a type of boat that has two hulls connected by a platform. They offer many advantages over traditional monohull boats, including increased stability and improved speed. This article will explore what exactly catamarans are and how they can be powered. We’ll also look at the differences between sailing and motor-powered catamarans to help you decide which one is right for you.

What Is A Catamaran?

A catamaran is a type of boat with two hulls connected by beams. It is usually powered by sails, although all modern catamarans come with inboard motors for propulsion. Catamarans are traditionally used for sailing, fishing, and leisure activities . They can be used in both fresh and salt water, and their light weight allows them to travel at high speeds without using much fuel.

Catamarans are known for their stability and durability due to their wide beam and shallow draft. This makes them ideal for traversing shallow waters or areas where the sea is choppy and unpredictable. They also have the advantage of being able to turn quickly and maneuver easily in tight spaces. Additionally, they provide a smooth ride despite rough seas since the two hulls help to reduce wave impact on the boat itself.

Advantages Of Catamarans

Catamarans offer many advantages to sailors and other seafaring travelers. The primary benefit of catamarans is their stability, due to the fact that they have two hulls that are connected by a platform. This design makes them much more resistant to waves than monohull vessels, which makes them ideal for activities such as fishing or leisurely cruises near shore. Catamarans also tend to be lighter, faster and more fuel efficient than monohulls, making them an attractive choice for sportier outings such as racing or overnight trips. In addition, catamarans can either be powered by engines or sails, giving you the flexibility to choose whatever type of propulsion suits your needs best.

Types Of Catamarans

Catamarans come in a variety of shapes and sizes, from luxurious yachts to fast-moving racing boats. They offer a unique sailing experience, with their twin hulls providing stability and comfort while still able to reach high speeds. Catamarans can be powered by engines or sail, enabling them to move swiftly through the water. Some are designed for serious racing, while others are equipped for leisurely cruising on the open waters. With so many options available, there is sure to be a catamaran that will fit any sailor’s needs. Whether it’s speed or comfort that you’re after, a catamaran can provide an unforgettable experience on the seas.

Sailing Vs. Motor-Powered Catamarans

Catamarans offer many advantages over monohulls and have become a popular choice for many reasons.. They are lightweight, stable, and provide ample space onboard. However, there is one major decision to make when purchasing a catamaran: whether to choose a sailing or motor-powered version.

Sailing catamarans have the traditional look of a boat with two hulls and tall sails, while motor-powered catamarans come equipped with engines and resemble more of a powerboat. Both types of catamarans offer their own unique benefits and drawbacks. Sailing versions are cheaper to purchase but require the sailor to be knowledgeable in sailing tactics in order to navigate easily. Motor-powered versions are more expensive but can be easier to operate in certain conditions due to their greater speed and maneuverability. In the end, it comes down to personal preference as both types can provide an enjoyable experience on the water.

Benefits Of Chartering A Catamaran

Catamarans are a type of sailing vessel with two hulls that are connected with a frame. They are typically very stable and have plenty of deck space for passengers and amenities. Catamarans also come equipped with two engines, so they can travel in calm waters even when there’s no wind to power the sails. The engine also allows them to get back quickly against strong winds or tides, making them great for long trips and passages.

The major benefit of chartering a catamaran is the amount of space it provides compared to traditional monohulls (a boat with one hull). This makes them ideal for larger groups, as they can accommodate more people without feeling cramped. Additionally, catamarans offer great stability in the water – even in choppy conditions – allowing you to feel safe and secure while onboard. Plus, since they don’t require as much maintenance as other boats, they’re perfect for longer periods of time on the water. All these factors make catamarans a great choice for any travel vacation with friends and family.

Frequently Asked Questions

There you are, out on the water when a strange craft approaches.  Is it a sailboat? It sure looks like one until it turns to face you.  That’s when you notice this boat doesn’t have just one hull. It has two hulls and it’s called a catamaran.

Catamarans are unique, and highly stable watercraft.  We’ll explore all the ins and outs of sailing the waters in one of these weird, and awesome multi-hulled craft.  Join me as we explore the wild world of sailing catamarans.

A small sailing catamaran sits on a beach.

A History Of The Catamaran

It is believed that the first people to use a catamaran design were those living in Australasia.

A map showing the region where the catamaran originated.

The succession of boat design in this region was actually very interesting.  The beginning of boats in the area was simple, albeit conventional rafts. These were fashioned from logs strewn together with plant fiber lashings such as those formed using bamboo fiber.  

Catamaran Evolution

An info graphic showing the progression of the evolution of the catamaran.

The conventional raft gave way to a minimal raft.  This design was basically a conventional raft with two cross beams added in the form of logs.  These would be eventually hollowed out to improve buoyancy.

The next step in the evolution of boats in the Australasian region was the double canoe.  This proved to be the first real catamarans.  

After some time, the form evolved further into the asymmetrical double canoe design.  In this design, one canoe was large and the other attached canoe was smaller.

The asymmetrical design quickly evolved into the single-outrigger boat like the one shown in the photo below.

A monohull canoe with an attached exterior outrigger is shown in this file photo.

The final stage of the evolution of the catamaran in the region was to gain a second outrigger.  This in effect created the trimaran with the single central hull and dual outriggers.

Eye Witness Accounts Of Catamarans

In 1697, William Dampier wrote of witnessing a type of seafaring vessel off the coast of Coromandel.  He noted how the locals called the type of boat a catamaran. He also noted that it had multiple hulls (logs) and that they were small vessels that the person operating would have to hang partway into the water, straddling the hull (log).

The name catamaran came from the Tamil.  And yet, it was easily applied by the European visitors to the two hulled sailing vessels that sped across the water in the region.

Although Dampier may have described the catamaran in the 1690s, the type of boat was actually used as early as the 5th century by the Tamil Chola dynasty.  They used boats to move their troops from one island to another. Using this design of boat allowed them to travel heavy, travel quickly and was partially responsible for the conquering of neighboring Burma, Malaysia, and Indonesia.

Building A Boat – Basics Of Catamaran Construction

A boat is usually thought of as being a single-hulled vessel that travels along the surface of the water.  It can have multiple types, shapes, and designs of the hull. However, it is often only thought of as having a single hull.  But, what if it had two hulls? Would that be like taking two separate boats, and making a raft over both of them? In essence, that is exactly what a catamaran is:  two boats made into one.

Advantages Of Multiple Hulls

  • More stability than a monohull
  • Wide supporting base allows for larger sails than monohull craft of the same length
  • Hull does not require the deep-running keel of a standard monohull sailboat
  • Less hull drag in the water than a monohull
  • Less power required to drive a catamaran forward than a monohull boat

Disadvantages Of Multiple Hulls 

  • Due to multiple hulls, construction is more expensive than a monohull design
  • Catamaran speed relies on lightweight materials to make a lightweight craft.  This also drives up the cost of construction.
  • Extra engineering requirements for multi-hull craft also increase the cost of construction.

Conclusion?  Well, it looks to me like everything about catamarans points towards superiority over monohulls in nearly every way.  But, you get what you pay for. I think the same thing likely applies to cars too. For instance, I have a performance car that cost me about 10k more than the equivalent non-sports car within the same class. 

Yet to drive the vehicle, it performs so much better than the normal version of the car, it really speaks volumes to the difference between a common vehicle, and a performance one.

Speaking of performance vehicles, let’s take a look now at the different kinds and uses of a catamaran.

Catamaran Types

Commercial catamarans – ferries.

Catamarans are often used as a ferry to transport people and vehicles across bodies of water as shown in this photo.

One of the most common uses for a catamaran is the commercial use of the vehicle design when it comes to ferries.  This is likely due to the wide, flat deck possibilities of a catamaran versus a monohulled boat. Not only that, but the catamaran is also a much more stable bodied vessel.  This again makes it a superior design for transporting larger land vessels like trucks and so forth. They can easily drive on the ferry without fear of the ferry tipping over.

Some ferries are designed for taking vehicles, like the one you might find in the city of Toronto.  Where it transports cars from the mainland to Toronto Island. Others are designed specifically with the sole purpose of transporting people. I took a look at one such ferry that operates in Germany.  Take a look at the following case study.

Commercial Use Case Study – The Ferry

The FRS Helgoline is a ferry catamaran operating out of Flensburg, Germany, close to the Danish border.

Top-rated boat seats on Amazon

According to the ferry company’s website, the ferry runs using four main engines which are run to a capacity of 12,182 hp combined.  This blasts this ferry at a speed of 35 knots or 65 km/hour. This is equivalent to 40 miles per hour. That’s pretty good considering the size and weight of the ship body this catamaran can carry.

Speaking of capacity, the ship can carry 680 passengers. At 56.4 meters long (185 feet) by 14 meters wide (45.9 feet), that’s a decent passenger capacity. 

Catamaran Passenger Capacity Versus Monohull Boat Passenger Capacity 

The general rule for calculating passenger capacity for a boat is as follows.

Length x Width / 15 = Passenger Capacity

Therefore, the FRS Helgoline should have a calculated capacity calculated as follows.

185 x 45.9 / 15 = 566  

But it actually has a capacity of 680 which is a 20% increase in capacity over a standard monohull.

For comparison, let’s look at a superyacht.  A 48.5m (159 feet) long by 10.7m (35 feet) beam (width of the boat) Palmer Johnson Supersport 48 (valued at about $28.5 million dollars) should have a capacity calculated as follows.

159 x 35 / 15 = 371

In short, 26 feet of difference in length equates to 309 fewer passengers.  It is almost half of the capacity of the catamaran at 26 feet longer length.

Commercial Catamarans – Service Vehicles

In port in Australia, a service catamaran sits docked in this photo.

Although Catamarans are typically used as ferries due to their stability and ability to carry wide loads on their flat decks, there are many different service catamarans out there as well.  From a support vessel to a crew transfer or search and rescue, catamarans are a solid and stable platform to build a ship on.

This is the Ardea which is a 20 meter (65.6 feet) catamaran to be used for crew transport and as a support ship.  This ship was built by the Echo Marine Group and delivered to Western Australia in early 2019. This particular vessel is in the service of the Cape Preston Sino Iron Project.  

Catamarans are used all around the world, for a variety of tasks, not just ferries or support craft.

Commercial Catamarans – Cruise Lines

A large red and white catamaran cruise ship sits idle in the waters in front of a bustling metropolis in this photo.

Now these are the catamarans we all want to be aboard, aren’t they?  Due to the wide stance, these ships can feature massive halls and wide-open interior areas.  These ships are stable, and some would say even more stable and safer than monohull design ships.  

There are many cruise ship catamarans in use today around the world.  Some of the more ‘famous’ catamaran cruises are those which investigate the Galapagos Islands.  There are several high-end, small fleet, cruise lines operating to the Galapagos which utilize catamaran design vessels as their primary ship type. 

These ships can be extremely comfortable and stable and often offer some reprieve to those who may otherwise feel seasick. It won’t stop the feeling, but the more stable the hull, the less the boat rocks around.

Military Catamarans

The USNS Spearhead races forward along the water in this file photo.

Catamarans make excellent military transport vessels.  They are stable and the potential to have a large, flat and wide deck for transporting land craft, troops or acting as a landing pad for vertical take-off aerial craft.  The stability of the two hulls makes the vessel an excellent candidate for military use, and thus it is used for said purpose.

A photo of the rear of the USNS Spearhead - a military catamaran.

As you can clearly see in the image of the USNS Spearhead, the rear of the vessel has a moveable ramp that can be used for loading and unloading land vehicles.  The interior bay of the craft is visible in the image as well, a large area for storage of vehicles, supplies and more. The crane arm on the back of the ship also shows how it is a versatile craft, set up to act as an excellent support craft with a helicopter landing pad and ample storage and freight capacity.

Recreational Catamarans

Siting on a beach, a small catamaran sail is set against the wind swept clouds and blue sky.

Catamaran Personal WatercraftThe wind is in your hair, the warm spray from the hull cutting over the edge of each wave as you skip over the water.  That is life, let me tell you. Personal watercraft have come a long way over the years and the small one, two, three and four-person catamarans have come a long way as well. 

This image shows a homemade catamaran.

Depending on the options, you can get a small one or two-person catamaran for as little as $1500 new.  That might be an inflatable though. There are some very nice, rigid hull designed catamarans for 1-4 people that range from $3500 to $15000.  And these are basically open, personal watercraft like that shown in the image below.

Using a small catamaran can be quite challenging to learn at first.  Sailing is not for the faint of heart. It requires skill, technique, knowledge of the wind and sea, and a bit of hard work.  But it can be fun, rewarding and a great way to catch some sun and fresh air out on the water. It’s a relatively GREEN sport as well.   Given the use of sails over gas-powered motors that is.

‘Sailing Cats’ – Sailing Catamarans – Yacht & Luxury Class

This photo shows a luxury sailing catamaran yacht.

Here’s where we get into the dreamy boats of the rich and famous.  I priced out a small 43’ luxury Leopard 40 sailing catamaran. Even before I added any extras at all, the base price was $399,000 USD.  I imagine if I added a few of the multiple extras available, and some tax, freight and that sort of thing, I’m easily in half a million dollars.  And that’s the smallest base model.

There are all kinds of luxury catamaran shipbuilders across the world.  From Asia to Europe and The Americas, it seems any major boating country has at least one company building luxury catamarans.  It’s weird that you don’t see more of them on the water though, don’t you think?

Being sailing vessels, these luxury cats require some training in sailing before you get behind the wheel.  And considering the price point, I would definitely want to be at least a semi-decent sailor with some good few years experience under my belt before I would comfortable at the helm of a half-million-dollar sailing cat.  It’s all relative I suppose. I imagine a billionaire might bat an eye at the prospect of wrecking a half-million-dollar boat. But to me, and most of you reading this, that’s likely a lot of money.

‘Power Cats’ – Powered Catamarans

A powered catamaran is shown in this file photo.

The powered catamaran is one of my favorite boats.  They have sort of a muscle car appearance with the wide and often tall front end of the boats.  I find it to be reminiscent of a large air intake on the front hood of a rally race car like the Subaru WRX, for instance.  These boats are fast, they are stable and handle very well. Catamarans are often considered the boat of choice for long sea voyages due to their stability.  

A powered catamaran will definitely cost more than a powered monohull boat of the same length.  Why? Well, the powered catamaran has one crucial downside. That is, it needs two engines. One for each of the two hulls.  Otherwise, it’s off balance for propulsion. These two engines or motors have to be in sync with each other or again, the propulsion will be off-balance.  Because they have two motors, they have double the maintenance when it comes to maintaining the propulsion system.

More components also means a greater chance of things breaking down.  In essence, it doubles the chances of the ship having a motor break down. The saving grace is that should one motor break, they have a backup, even if it does mean very unbalanced propulsion.  In contrast, a monohull vessel of the same length may only have half the chance of motor failure due to only having one motor, but if that one motor breaks, then what? Call for help, that’s what.  A cat would have a struggling chance to get itself back to port. A monohull would be dead in the water unless it was carrying spare parts or another motor onboard somewhere.

Catamaran Frequently Asked Questions

What is a catamaran cruise.

definition of catamaran boats

A catamaran cruise is simply a cruise on a dual hull design boat.  Often used for river cruises, the catamaran which is used as cruise ships are often considerably smaller than their giant monohulled counterparts.

What is the purpose of a catamaran?

A catamaran is a design for a boat that utilizes two hulls.  Due to the flat, platform-like-potential for the deck of the boat, the catamaran is often purposed with transporting materials, vehicles, and people.  For instance, catamarans are quite often used as ferries.

Is catamaran safe?

Catamaran are very safe water craft.   The design of riding on two hulls separated by a gap in between, in essence is like giving a car a double-wide wheel base.  The wider the stance, the more stable the craft, from side to side anyway. And if the length of the boat is proportional to the width, then it becomes an extremely stable craft.  That is why catamarans are often considered the best to be used for long voyages. Yes, catamaran are safe.

What is the difference between a catamaran and a sailboat?

A traditional sailboat is a deep, monohull vessel that has at least one mast extending high into the air above the deck to hold sails.  A catamaran refers to the design of a dual-hull boat and really has nothing to do with sails. Although, catamaran do make excellent sailing boats as well, they are quite capable of acting as power boats and do not require sails if they have the correct amount of powered motors to propel them.  Sailboats, although also able to be powered if a motor is provided, are traditionally monohull and wind-powered exclusively.

Do catamarans have small interiors?

The size of an interior cabin on a boat is typically proportional to the size of the boat itself.  If a catamaran has above-deck cabins, they will likely be able to be of a larger design than those you would find on deck of a monohull boat.  This is because a catamaran has a much wider footprint than a monohull boat of the same length. This extra width would allow for larger on deck cabins.  

How much does a catamaran cost?

A personal watercraft (1-2 person) inflatable catamaran will run you anywhere from $1500-$12000 USD, depending on the quality and features.  The rigid hull catamarans of the same size start at about $4500 USD.

Top-rated boat lights on Amazon

A small cabin cruiser type of catamaran will typically start at about $60000 for a small base model and the price just goes up and up depending on size and features.

For Instance, a 40’, 3 cabin with 1 washroom cat will cost you about $500,000 USD for the base model.  They are considerably more expensive that a monohull of the same length. However, the trade-off is greater stability and a smoother, more comfortable ride.

Is a catamaran more work to maintain?

Technically yes.  Due to having two hulls and if powered, two motors and likely also water jets, this means you have double the oil changes of a boat that would have a single motor.  Once you get past the basic engine and hull maintenance, a catamaran is not that much more work than a monohull ship of the same length.  

The trouble with catamarans in terms of maintenance, is that once they reach a certain length, the width becomes more than a standard lane on the road.  That being said, if you ever need to transport the boat via land, it can be quite the challenge. Especially if you need to pay to have a police escort for an extra-wide trailer.  And special licensing might be involved as well.

What is the difference between a catamaran and a trimaran?

A trimaran is shown in this photo.

A catamaran is a dual hull boat.  In other words, it has two hulls. A trimaran has three hulls.  

Is a catamaran considered a yacht?

According to Oxford dictionary, a yacht is a medium-sized sailboat equipped for cruising or racing.  A catamaran, on the other hand, is a boat with two hulls. Therefore, a catamaran can most certainly also be a yacht.  And likewise, if a yacht has two hulls, then it is a catamaran as well.

Can you get seasick on a catamaran?

Seasickness occurs when a person feels nauseous from the swaying motion of a rocking ship.  These feelings may be lessened on a catamaran, due to their extra stability. However, a catamaran may be slightly more stable than a monohull of the same length, but it is still a boat.  And it will still make someone who experiences seasickness continue to feel the ill effects.

Are catamarans more stable in rough seas?

Catamarans are known to be more stable than monohull ships of the same length.  This is why catamarans are often the ship type of choice for long sea voyages due to their stability.

Why do catamarans capsize?

Catamarans are not known for capsizing.  The larger vessels that is anyway. But, it does happen from time to time.  Catamarans are known for their stability, so typically if a capsize event should occur, it is typical for them to be extreme circumstances.  

Top-rated canoe accessories on Amazon

Personal watercraft catamarans are a different story though.  These are in fact known for tipping over. Not because they are less stable than their monohull counterparts of the same length.  But instead, because they are able to go considerably faster than monohull personal watercraft of the same length (not including powered craft though).  This is due to the sailing cats being able to have a larger sail than a small monohull sailboat of the same length.

Due to the extra sail, they are able to travel faster than monohull sailboats of the same length.  This allows them to whip around on the water and at higher speeds, whipping your cat about quick can easily send it over sideways. Extra speed means fast turns carry momentum in the direction of travel and that extra speed equates to tipping over if turned too fast.  To sum up, they capsize due to user error or extreme events.

Which is safer, a catamaran or a monohull?

Due to the extra stability of having a wider footprint than a monohull, a catamaran of the same length is the safer vessel.

Are catamarans safer than sailboats?

The same rule applies to stability versus the length of the hull.  A cat will always be the more stable length for length. However, due to their ability to go much faster than a monohull sailboat, this kind of cancels out some of the added safety due to stability.  With that in mind, they may just be about the same but there is one generalization we can make when comparing the safety of catamarans vs sailboats: At the same speed, and of equal length, sailing or power catamaran will be safer than a monohull sailboat.

How fast can catamarans go?

The speed a catamaran can go is entirely dependent upon the hull design, weight of the vessel, the strength of propulsion (be it wind or powered) and so on.  The general rule is that in terms of sailing cats vs monohull sailboats, a cat of equal length can typically go faster than a sailboat.  

In terms of powered cats vs powerboats, a powered catamaran will typically require less energy to move forward than a monohull of the same sort of hull design (but monohull of course) and thus a cat should, in theory, be able to go faster than a monohull when both are using propulsion that is equal in power.

What Is a Catamaran?

If you’re thinking of chartering a catamaran on your next trip, read through our guide and get up to speed on two hulled yachts! We offer Catamarans for charter in over 60 countries and the entire selection can be seen on our Catamaran charter page.

A Catamaran is a sail or engine-powered boat with a double hull, a distinct feature that makes it immediately recognizable once you're aware of the design. People often question whether a catamaran is a yacht, and due to the sleek style, versatility, speed capabilities, and comfort, a catamaran definitely earns the yacht stamp of approval. Due to these same characteristics, catamarans are becoming an increasingly popular choice among avid leisure and sport sailors.

The elegant and unique catamaran style isn't a new development - it's actually a centuries-old design that's been modified and built upon to become what it is today.

The first Catamaran was created in India, borrowing its modern name from the original Tamil word kattumaram, meaning "logs bound together". The first design was simply a raft made of tree trunks, built in the fishing communities of Tamil Nadu in southern India and used to invade several Southeast Asian countries as early as the 5th century. The kattumaram quickly became the favoured vessel style throughout Polynesia and Micronesia.

Evolved by American Nathanael Herreshoff in the 1870s and further developed in the 1950s, the catamaran concept really took off in the 20th century. It was soon functioning as a full-fledged yacht, able to compete in the racing arena with mono-hulled boats without compromising luxury. Nowadays, catamarans attract both sport and leisure boaters with its versatility, speed, and comfort.

What Is a Catamaran?

What are the Characteristics of a Catamaran Hull?

The most obvious characteristic of a catamaran is the twin hull, but there are more benefits to the cleverly crafted underside. When compared to a monohull yacht of the same size, the catamaran hull has several big advantages. Catamaran hulls are noted for having less volume, lighter displacement, and shallower draft (ie less of the boat is below water) when compared to monohull vessels. The shallow draft is especially appealing, allowing for use in shallow water and giving the captain the option to pull the boat right up to shore without worry.

Additionally, because of the hull design, catamarans boast a smaller hydrodynamic resistance, ultimately making them more economic since they don't need as much fuel to propel them forward. And for those sailors still strengthening their sea legs, the double hull increases the catamaran's overall balance and stability by reducing the amount of wave-induced motion. So long seasickness!

Catamarans have a lot of space. The living area in between the two hulls offers a dining and lounging area as well as a spacious kitchen. You also find outside lounging areas at the back and in the front of the yacht. The various places to relax mean a lot of privacy on board. The two hulls further increase the privacy aspect because the cabins are separated by the central living area and each hull has their separate entrance in most cases. This makes the Catamaran the ideal yacht to charter for two couples, two families, a group of friends or a large family. The cabins in the hulls are spacious and comfortable and their sizes vary with the exact Catamaran model.

So in summary, catamarans:

  • have two hulls, usually connected by a bridgedeck
  • can be sailed in shallow water
  • use less fuel, because they have low hydrodynamic resistance
  • tend to be very stable
  • have a lot of space for dining and lounging and preparing food
  • offer greater privacy than monohull yachts

To give you an idea of the space and amenities on board a Catamaran, do have a look at the many pictures of our Fountain Pajot Alegria 67 for charter in the British Virgin Islands .

How to Sail a Catamaran

You're sold on the idea of a catamaran, but now comes the question, how hard is it to sail a catamaran? Learning how to sail a catamaran is relatively straight forward if you're already trained in the basics of sailing. Although it does differ from monohull vessels, the idea is the same. Be prepared to tweak your sail trimming skills and get used to the difference in motion (or lack thereof) with the catamaran.

The catamaran is gaining popularity because the better-balanced hull and twin engines make it arguably easier to operate than a monohull yacht. Fluid maneuverability means that even one person can sail a catamaran as long as they've built up enough sail experience. Still, it's never a bad idea to get some formal training; the ASA and RYA both offer catamaran sailing courses to help enhance your skills.

How Fast Can a Catamaran Sail?

Catamaran's can cruise! Their speed is just another reason why the boat has become so sought-after in recent years. A sailing catamaran can typically perform 25% - 30% faster than a monohull of the same size.

So just how fast can they go? Cats average about 10 knots with top speeds reaching around 15 knots. Just keep your weight in mind - catamarans respond sensitively to heavy loads and will perform slower if overweight.

xl_1200_Leopard-48_Light-25.jpg

Why Charter a Catamaran?

When compared to a monohull boat of the same size, a catamaran has a tendency to be a bit more expensive to charter. However, your trip itinerary might require certain criteria that make spending a bit more worth it. For example, the flat plane and stability of a catamaran are ideally suited for a family to enjoy their holidays in a lot of comfort. It is also ideal for a scuba diving holiday , allowing divers to gear up and enter/exit the water with ease. Additionally, big parties usually find catamarans better suited for their needs in terms of deck space and overall comfort.

A Catamaran is the ideal yacht for a relaxing vacation as it boasts a lot of space, stability and living spaces - it truly is your floating hotel. But note that a catamaran holiday does not need to break the bank and is very affordable in comparison to a vacation in a hotel or a villa depending on the type and size of a catamaran you decide to go for.

Catamarans are a fun alternative to the traditional sailing yacht and the value for money is unrivalled for a yacht holiay. They provide comfort, flexibility and a lot of space to spend your time on the sea. You can also check out this Comprehensive guide to chartering a yacht for more information.

Catamaran Boats: Types, Uses & Activities

catamaran boats

Let’s look at some of the types of catamarans and their best uses.

Sailing Catamarans

Sailing catamarans have made great strides over the past several decades. Small daysailing cats are popular because they provide a safe and simple learning platform and you’ll find fleets of them in resorts where they’re used by people with very little sailing experience. These types of small cats are usually made of roto-molded plastic or fiberglass and they typically don’t have auxiliary engines so their sole source of propulsion is sails.

Larger sailing cats have taken over the world of distance cruising and bareboat chartering . Nearly all tropically-based bareboat charter companies offer more sailing catamarans today than monohulls and those numbers are also growing in destinations such as the Mediterranean. Typically, charter cats have two engines, one in each hull, to maneuver as well as a mast that supports a mainsail and at least one headsail.

Explore Sailing Catamarans & Sailboats

Power Catamarans

Power catamarans, often referred to as "multi-hull powerboats" or "power cats," have larger engines than their sailing cousins and no masts or sails. Their bigger motors give them higher top speeds but these cats also need reinforced hulls to handle the weight and power of these engines. Other than pontoon boats (which arguably are also power cats), motorized cats are the fastest growing segment of the boating market.

Power cats come in various shapes and sizes. Numerous smaller power cat brands are marketed for fishing while larger ones are popping up in bareboat charter and as cruising platforms. Many commercial passenger ferries have also turned to the catamaran design for their spaciousness and speed.

Advantages of Catamaran Boats

There are some inherent advantages of boats with multiple hulls, which include:

  • More deck and interior space per foot than monohulls. A catamaran has about 1.2 times the space of a monohull. In other words, a 40-foot cat should have the deck and interior space of a 50-foot monohull. Cats also have more interior space with up to four cabins even in a vessel under 40 feet in length. These large cabins usually provide easier berth access and they have hull windows with opening ports for better ventilation and light even in the staterooms, which are usually more separated for privacy.
  • Due to their design with two hulls set wide apart, cats enjoy greater stability under way and at rest in rolly anchorages . Unlike a monohull that can heel under sail or roll when powered, cats stay level, which makes them safer and easier for people and pets to maneuver on the flat deck. Some say cats have an easier motion than monohulls and tend to induce less seasickness.
  • With twin engines, cats’ propellers are set wide apart so these boats have excellent maneuverability. Cats can venture into shallower waters too – especially sailing cats that don’t have deep keels. Because cats don’t drag a massive keel through the water, they’re also on average 20-30 percent more fuel-efficient even with two engines.
  • Larger, more sophisticated power and sailing catamarans have a natural redundancy built into their equipment inventory, which translates to comfort and safety. For example, if a fresh water pump fails in one hull, there’s usually another to provide water for washing up. If one engine fails or one propeller spins off, there’s another to get the vessel to homeport safely. There’s also more room for the installation of additional systems like generators, watermakers, battery banks, and more.

Drawbacks of Catamaran Boats

Like any boat type, there are a few small drawbacks when it comes to catamarans:

  • Catamarans take up more space so it’s often difficult and expensive to find dock space.
  • Due to their design, both power and sailing cats can also slam the bridge deck into oncoming waves when going to weather.
  • Additionally, sailing cats don’t necessarily sail as well upwind as monohulls because with two hulls, they simply can’t point as high into the wind.
  • Finally, it may be tempting to load up a catamaran due to the space it offers but a sure way to damage a power or sailing cat’s performance is to overload them or have uneven weight distribution—something, which is less of a problem on their monohull counterparts.

Catamaran Boats FAQs

Whether used for daysailing, world cruising, chartering or fishing, boats with two hulls are growing in acceptance and appeal. The basic design may be hundreds of years old but today’s updated designs make catamarans a viable option for any boater.

Are catamarans more expensive than monohulls?

Purchasing or chartering a catamaran is usually more expensive than a monohull since there are more accessories and even more fiberglass construction to pay for. Over time, cost of ownership can be higher too since there are two hulls to polish and wax and more equipment to service or replace. It’s also more expensive to haul out a catamaran for bottom work.

What is the typical draft of a catamaran?

Draft (depth below waterline) depends on the size and type of cat. Small daysailing cats can draw mere inches but with a large cruising cat, it may be 3-4 feet. Some cats have dagger boards that are used to improve upwind performance. With the boards down, a cat can draw 10 feet or more but these boards may be lifted to allow access to shallow water.

Can catamarans be raced?

Catamarans make fine racers as has been proven by the America’s Cup contenders. There are also one-design classes in the smaller, open designs.

What Is A Catamaran?

Everything you need to know about catamarans before you set sail!

As the summer season approaches, California is gearing up for an influx of visitors from all over the world. Most tourists flock to San Diego for its laid back vibe and gorgeous beaches.

Not just that, but most visitors also love this city because of the sheer variety of things you can do there. You can go fishing, kayaking, snorkelling, swimming, tanning, and catamaran sailing in just one trip to San Diego.

But most people don’t know what catamaran sailing is before visiting America’s Finest City. There’s no need to worry, though. This article will tell you all there is to know about catamaran sailing.

If you hear someone mention a cat while talking about sailing, they’re most probably referring to a catamaran! A catamaran is a yacht or a boat with two hulls parallel to each other.

It has a broad base that is supported by the two equally spaced hulls and is a lot more stable than a monohull boat. Most people usually use them for recreational purposes such as going on a cruise or a fishing expedition.

You shouldn’t confuse a catamaran with a trimaran, though. A catamaran has two hulls, while a trimaran has three. Cats also face a lot less resistance because of their twin hulls so they can cut through the water more easily.

Because of that, they need less propulsive power to move as compared to a monohull of a similar size. Catamarans can be of any size, from small sailing ones to huge ones that people use to ferry cars.

Catamarans are more stable than monohulls because the two widely-spaced hulls balance the weight of the vessel in such a way that the water doesn’t make it bob from side to side too easily. It also allows the manufacturers to give the boat a broad base, making the catamaran spacious and comfortable.

These vessels can also hold more weight than a monohull of comparable size, which means you can rent a catamaran to spend time with a large group of people, such as your family or friends.

Why You Should Rent A Catamaran

The waters of San Diego are perfect for renting a catamaran. The fresh breeze, the California sun, and the lively waters make sailing a catamaran a lot of fun there. All you need to do is find a reliable catamaran rental company to get a perfect catamaran for your holiday.

There are several reasons why you should rent a catamaran. Let’s talk about them.

If you or anyone in your travel group is scared of sailing, a catamaran might be just the thing for them. Its twin hulls allow the catamaran to sail smoothly so that the people sitting in it don’t feel a thing. It’s ideal for people who want the sailing experience with the scary bobbing and swaying.

A catamaran has a lot more space than a traditional monohull or a speedboat. Hence, you can take a large group of people with you to maximise your enjoyment. The more, the merrier!

Generally, the two hulls join together to form a large stable platform that has around four cabins; one in each corner. Most San Diego yacht rental companies use the central space as a seating or dining area. You can also just lounge there to look at the spectacular views passing you by.

Less Seasickness

Some people love to go out on the sea but don’t do it often because sailing on nearly any kind of vessel makes them seasick. The way most monohulls have rocky movements on the sea induce vomiting and nausea in a lot of people, making them unable to enjoy the trip.

A great solution to this problem is renting a catamaran. A catamaran doesn’t move from side to side while sailing the way all other boats do. Since it has a hull on each side, the weight o the vessel is equally distributed, causing it to stay stable while sailing.

This characteristic induces less seasickness in susceptible people, so if you’re one of them, contact our San Diego yacht rental company today for a smooth ride on oour catamaran yacht.

Increased Safety

Catamarans have increased safety as the manufacturers install two engines in them. In the event that one fails, the other will do its job just fine, allowing you to have a safe and uneventful journey. In addition, the increased stability of the catamaran will enable you to feel minimal disturbances in case your yacht encounters a storm or rough waters.

Whether you want to have a relaxed holiday with your family or a fun-filled holiday with your friends, you can’t go wrong with a Catamaran. Luckily, we offer excellent packages for the upcoming season, so don’t forget to enjoy the San Diego coastline with a catamaran trip. Give us a call today to book your adventure!

Catamaran Parts Explained: Interactive Guide (For Beginners)

As an Amazon Associate, we earn from qualifying purchases. We may also earn commissions if you purchase products from other retailers after clicking on a link from our site.

Learning a new skill can sometimes be time-consuming, and learning to sail also means learning a new language with tons and tons of new words that, in the beginning, makes no sense at all.

Some of the words you will read about in this article stem from the early days of sailing. Some are only a decade old; in this article, I have tried to compile all the basic terminology that I believe a beginner needs if he or she wants to understand sailing and catamarans.

Feel free to use this article as a resource and come back to it when you want to look something up or just to learn more!

Table of Contents

Main sections on a catamaran

  • Hulls; are what separates a cat from other sailboats, a catamaran has two hulls, a trimaran three, and a regular sailboat, aka monohull, has one. The hull is the part of the sailboat which makes it float and to where all other things are attached. The hulls are usually divided into sections, such as usable and non-usable area. An example of a usable area is the engine room.
  • Cockpit ; is from where the boat is maneuvered; it is to here that all halyards, sheets, etc. go. The cockpit contains navigation and steering equipment and is from where the sails, rudder, and engine are controlled.
  • Deck; is the top part(roof) of a catamaran covering the hulls and bridge deck. The deck is made hard enough to walk on. To the deck, attaches lifelines and other equipment.
  • Sugarscoops ; are the aftmost part that gets their name from their scoop-shaped appearance; this is where the deck/cockpit meets that water and usually encompasses a stair or ladder for easy access depending on the size of the boat.
  • Cabin; is basically any area on the inside of the boat that is protected from the weather and is made to offer the crew space to rest, eat, and hangout. Inside the cabin, you will find berths (beds), a galley (kitchen), and sometimes specialized areas for repairs or storage.
  • Bridgedeck; connects the two hulls; the inside is the cabin, the top part is the deck, and the entire unit is called the bridge deck. Bridge deck clearance, the bridge deck’s height above the water, is an important factor on a catamaran since a too small clearance will create excess noise and vibrations and fatigue not only the crew but also the boat.

Main areas on a catamaran

Bow (front).

Nothing complicated here; the bow is just a nautical term for the foremost part of your boat. This is where the waves and the sea first meet the hull and depending on the type of boat, the bow(s) can be shaped differently.

Center (Middle)

The part between the bow and the stern is rarely called the center part( middle) of a boat; more common is to speak about the specific area situated within the middle part of the vessel, such as the cabin or the mast.

  • Cockpit; as mentioned above, here you will (usually) find everything that you need to maneuver and navigate the boat, such as a compass, GPS, sheets, steering wheel, and throttles for the engines. Some boats may not be set up this way and require you to move around the boat to access certain controls.

Cabin (inside of the boat)

The boat’s interior is where you will find everything that is made for the crew’s enjoyment; it is a place to eat, sleep, rest up, and hide away from nasty weather.

  • Berths; is a bed; sailors need to sleep too!
  • Galley ; is another name for kitchen, usually set up in a very primitive way with a gas stove on a stabilized platform to ensure your food won’t get tossed around.
  • Navstation; or navigation station, is a place, usually with a table, chair, and equipment for planning and logging a journey.

Stern (Back)

Stern is the name for the rearmost part of the boat; there is no clear definition as to where the stern stops and other parts begin, so it is something that the crew will have to figure out on their own through good communication.

Communicating directions on a sailboat

Not only will you have to know the different names of different areas on the boat, but it will also be essential to communicate clearly in what direction something is happening, for example, in a situation where you, the captain, want the crew to observe in a specific direction or pick up a piece of gear somewhere on the boat.

Communication on a sailboat is vital when you want to sail safely and efficiently; here, I have listed the words or phrases used to communicate a direction.

  • Forward; easy as it sounds, it is the same direction as where the bows are pointing. When giving directions towards or beyond the bow, you will use the word “forward” for example; the fender is located forward of the mast.
  • Aft ; is the behind the boat. When you are giving directions towards the stern, you will use the word “aft”; for example, the cockpit is located aft of the mast.
  • Port ; this will be your left side. Fun fact, in the good old days, you would always dock with the port on your left side; hence port is the left side. If you ever forget which one is which, “port” has 4 letters and so has the word”left”!
  • Starboard ; is your right side!

Types of sails

Sails come in very different shapes and sizes and are a science in itself; in this article, I will focus on the mainsail and three common types of staysail.

  • Mainsail; is, per definition, the sail attached to the mast; its sideways movements are controlled by the boom. When the mainsail is triangular in shape, as on most modern sailboats, it is called a Bermuda rig. Most mainsail uses something called battens.
  • Staysail; mainly comes in two versions, a staysail that does not overlap the mainsail is called a jib. A staysail that is larger and thus overlaps the mainsail is called a genoa.
  • Spinnaker ; is a big balloon-like sail that replaces the jib when sailing downwind.

Parts of a sail

  • Luff; the front part of the sail, is connected to the mast through a rail system which makes it possible to hoist or reef.
  • Leech; the back part of the sail.
  • Foot; the bottom part that reaches from the clew to the tack.
  • Clew; back bottom corner.
  • Tack; is the front bottom corner (remember “tacking”?).
  • Head; is the top triangle of the sail and this is where the mainsail halyard attaches.
  • Battens; are pieces of flexible material sewn into the mainsail to increase its aerodynamic shape. Battens can be full length or partial length.

Standing rigging

Everything that keeps the sails and mast upright are parts of the standing rigging; it is comprised of wires, cables, and lightweight metal structures.

  • Forestay; usually a metal wire running from the top of the mast to the bow, is sometimes combined with an inner forestay that connects to the mast at a lower point. If the forestay attaches to the top of the mast, the setup is called a masthead rig; if it attaches lower, it is called a fractional rig.
  • Backstay ; same as the forestay but attaches to the stern; most catamarans do not employ a backstay system but instead moves the side stays aft.
  • Shroud ; much like the forestay but stabilizes the mast sideways and runs from the top to the port or starboard side. Spreaders are used to change the angle of the wire against the mast and better support the mast.
  • Sidestay ; connects to the mast below the shrouds and is not pushed outwards with spreaders. On a catamaran, these attach aft of the mast to eliminate the need for a backstay; this makes it possible for a fully battened mainsail with a large roach.
  • Jumpers; are used on a fractional rig with diamond shrouds to add structural integrity to the mast without adding excess weight.
  • Bowsprit; is a pole amidship at the bow that allows for separation of the tacks (foremost, lower part of the sail) for increasing sail efficiency when using two headsails.

Other stabilizing parts

  • Spreaders; act to lessen the angle between the shrouds and the mast; a wider angle will result in forces acting sideways (stabilizing) instead of up and down (bending). This increases stability and decreases the risk of unwanted bending of the mast.

Running rigging

The running rigging on a catamaran is any piece of equipment used to control the shape of the sails, including what is needed to raise them.

  • Sheet; are the ropes (or wire, cables, etc.) that connect to the clew of a sail; on a catamaran, it connects to the staysail (genoa or jib, depending on the shape).
  • Mainsheet ; is the rope that makes it possible to change the mainsail’s angle; the mainsail can only move in a port to starboard direction(right and left) and not up and down.
  • Staysail sheet ; is called after whatever type of sail it is connected to, i.e., jib sheet or genoa sheet. Worth notice is that since the staysail operates on both sides of the catamaran (depending on if your tacking or gybing), it is connected with two ropes, one for the port side and one for the starboard side.
  • Halyards ; are the ropes that connect to the top of a sail and make hoisting (or raising) possible. Halyards have different names depending on what sail they are raising, such as Mainsail halyard or jib halyard. Not to be confused with sheets that act upon the sail once they are already hoisted. If the staysail is using a roller furling, then “hosting” is done differently.
  • Furling line; is used together with a roller furling and makes it possible to spool up the sail on the forestay instead of raising and lowering. This makes for a faster and easier way to reduce sail area.
  • Reefing lines; reefing is when you lower parts of your sail to reduce the sail area and reduce the boat’s power and speed; reefing lines are put through holes in the mainsail and attach to the boom.
  • Boom vang; is connected between the boom and deck; it is used to change the mainsail’s shape by pulling downward on the boom. (not very common on Catamarans)

In this category, we will look at the hulls and some of the vital parts that attach to them under the waterline.

  • Hulls; differ in their shapes depending on the boat’s purpose, a racing cat would have narrower hulls to reduce drag, and a cruising cat wider hulls to encompass more storage.
  • Rudder; is what changes the direction of the boat. When water passes around the rudders(two on a catamaran), it creates a “pushing force” that makes the boat turn. The rudder is connected to a steering wheel or a tiller at the cockpit through chains and linkage.
  • Centerboard and daggerboards ; are sorts of keels that can be raised or lowered to attain certain sailing characteristics. When the keel is up, drag is lower, and so is the draft (how deep the boat sticks in the water). A small draft makes it possible to travel in very shallow waters. The difference between a daggerboard and a centerboard is that a centerboard swivels into place, and a daggerboard is pulled straight up.
  • Mini-keel; is just what it sounds like; it is a keel but very small (a few inches deep) and has no ballast.
  • Crossbeam ; is a multihull-only feature and keeps the two hulls from moving in relation to each other. If the crossbeam is damaged or nonexistent, the bridge deck is the only thing that keeps the hulls in place. This will increase wear and sooner or later lead to cracks, or even worse, separation of hull and bridge deck.

Most catamarans have two engines, one on each hull aft the stern; usually, they are internal with only the propeller in the water. The other option, which is cheaper and most often found on smaller boats, is to have one outboard engine placed amidship (middle).

  • Inboard ; engines are situated in a compartment inside the boat at the stern. On an inboard engine, the propeller and the shaft are the only parts outside the hull. Sometimes the prop shaft (propeller shaft) is replaced by a sail drive.
  • Outboard ; is a standalone engine usually mounted on the bridge deck amidship(if only one is used) or mounted at the sterns when used in pairs. They are linked together with pushing rods and wires so it can be manipulated from the cockpit.
  • Saildrive ; is a type of gearbox that is quieter and vibrates less than a regular propeller and shaft setup.
  • Propeller and shaft; are the most common and cheapest way to propel your boat. It is basically just a watertight axel that sticks out of the hull, and at the end of it, you’ll find the propeller.

There are so many pieces of gear aboard a catamaran that an all-encompassing article would probably fill up the entire internet. Below I have listed the most common equipment that you will most likely encounter on any sailboat.

  • Winches; makes handling lines and ropes much easier. Instead of pulling them with your bare hands, you loop them around your winch and use the handle to crank. Winches come in mechanical style or electrical style.
  • Anchors ; is basically just a big hook made to stick to the bottom of the sea. Anchors have different shapes and weights depending not only on the seabed but also on the boat’s weight and size.
  • Navigation ; compass, GPS, and maps are all vital pieces of equipment making your trip safe.
  • Cleats ; is any equipment that is made to fasten a rope. Cleats come in different configurations; jam, cam, rope clutch, or the most common horn cleat.
  • Block ; is a device that can be used in pairs as a pulley (to reduce the force needed to lift something) or on its own to reduce the friction of a rope when the rope can not be drawn in a straight line.

Americans whose yacht was hijacked in Grenada were likely thrown overboard and died, police say

Two Americans are presumed dead after they vanished from their yacht in Grenada , leaving behind evidence of a bloody struggle, police in nearby St. Vincent and the Grenadines said Monday.

While loved ones of Kathy Brandel and Ralph Hendry are hopeful that the American retirees and sailing enthusiasts could still turn up alive, St. Vincent and the Grenadines Police Superintendent Junior Simmons offered a more somber assessment.

"Based on the investigation thus far, it is presumed that Ralph Hendry and Kathy Brandel are deceased," Simmons said in a video statement Monday afternoon .

Kathy Brandel, front left, and Ralph Hendry, front right, with family.

Hours earlier, police in Grenada said there's still hope to find the couple.

But Royal Grenada Police Commissioner Don McKenzie also said he's offering “condolences” to the family of the two American boaters, who were most likely “disposed of” at sea by escaped prisoners. McKenzie said there's a “low probability” Brandel and Henry might be alive.

Three accused criminals escaped from jail on Feb. 18 before they "commandeered" the couple's boat, called Simplicity, and headed north, McKenzie said. Police have said the escapees boarded the boat while it was docked in the St. George area of Grenada.

"They headed to St. Vincent and the Grenadines. Information suggests that while traveling between Grenada and St. Vincent, they disposed of the occupants," McKenzie told reporters.

Asked whether investigators have an idea where the "missing" Americans might be, McKenzie flat-out said, "No."

"We have nothing conclusive to say that the individuals are dead," he added. "We still hold out hope that, in spite of what might be a low probability, they will turn up alive somewhere, that they're alive."

Simmons in St. Vincent and the Grenadines left little doubt of his opinion in the probe “into the disappearance and presumed death of two United States citizens ... Ralph Hendry and his common law wife Kathy Brandel.”

In an interview that aired Monday on NBC Nightly News, Rob Maher, a friend of the couple who acted as their emergency contact, said that the situation was “like a bad Hollywood movie.”

“It’s hard to think of their last moments with the idea that they might have been thrown overboard alive. It’s difficult to conceive for a friend,” he added.

Couple's sons are in the Caribbean

The couple’s sons called the pair’s disappearance “the rarest of the rare occurrences.”

Brandel’s son, Nick Buro, and Hendry’s son, Bryan Hendry, told NBC Washington that they first learned the couple were missing after U.S. consular officials in Barbados contacted them.

A good Samaritan who found the pair’s abandoned boat contacted the Salty Dawg Sailing Association , whose flag was flying on the mast, and word made it to the two sons, too.

They said they were told the couple vanished after three men escaped from police custody Feb. 18 and boarded their boat in Grenada the next day, Buro said.

Buro said they were told an “altercation of violence took place" on the boat, adding that there was evidence of the violence and that the couple’s possessions were "strewn around all over." Items had also been stolen.

McKenzie said, "What I can say to the family is my condolences and we are still hoping for what I consider a positive outcome, which is we still have the hope that our worst-case scenario will not be a reality."

The scene on the couple's boat was "consistent with signs of violence," Simmons in St. Vincent and the Grenadines said.

"Several items were strewn on the deck and in the cabin, and a red substance that resembled blood was seen on board," he said. "There was no discovery of bodies on board the yacht."

The escapees were caught by police in St. Vincent and the Grenadines on Wednesday and are in custody there, according to Buro and officials.

Police told Buro that they have questioned the suspects multiple times, and he said the family expects charges soon.

Buro and Hendry are in the Caribbean and have been speaking with authorities, including the St. Vincent and the Grenadines police and coast guard, and they expressed their appreciation.

A spokesperson for the U.S. State Department said it is aware of the reports involving two citizens missing in the vicinity of Grenada and St. Vincent and the Grenadines but did not identify the couple. The official added that U.S. authorities are coordinating with local law enforcement officials as they carry out their search efforts.

“We are monitoring the situation and seeking additional information,” the spokesperson said. “The Department of State has no higher priority than the welfare and safety of U.S. citizens abroad. We stand ready to provide appropriate assistance to U.S. citizens in need and to their families.”

Life on the water

The couple met in Virginia and have been married for 27 years. They raised the boys together in the state, where they lived until 2013, selling their home in Alexandria to trade it in for Simplicity and life on the water.

"They wanted to see the world. They wanted to experience life. They wanted to see what the world had to offer outside of their small window of living in one place and being mobile and being able to have a different adventure every day — that’s like the definition of living," Buro said.

Buro said that the family has always been close and that they talk often. He considers Ralph Hendry his father and Bryan Hendry his brother, and he said he knows Hendry feels the same way about him and Brandel.

The couple “lived with a sense of wonder and love,” Hendry said.

“They loved immersing themselves in different cultures and meeting people and spreading their love wherever they could,” he said.

Buro echoed his stepbrother’s sentiments.

“You’ll never meet more beautiful people than Kathy and Ralph,” Buro said. “They were there for people when they needed it most, and I just, they’re my inspiration for everything, and I can’t express how much I love them, and I know everybody else who knows them feels the same way.”

The couple had been planning the trip down to Grenada — their first to the Caribbean island — for “years and years and years, training themselves, preparing the boat, preparing themselves ... to make the trip,” Hendry said.

It was going to be a “very long trip, not to be taken lightly,” and the couple felt they had “prepared themselves adequately,” Hendry said.

They made the voyage down with the Salty Dawg Sailing Association, and everyone arrived safely, Buro said.

Bob Osborn, the association's president, said the situation was upsetting and tragic.

“In all my years of cruising the Caribbean, I have never heard of anything like this,” he said in a statement.

Yacht 'was their home'

Buro thinks his mother and stepfather could still be alive.

“We still think there’s a chance that they’re out there," he said. Because the investigation continues and St. Vincent and the Grenadines police were "quick to apprehend the suspects and are searching," there is hope.

"We still hope that they are OK and that we can bring them back," Buro said.

He said that the entire situation "is something that is completely unexpected" and that they are trying to understand the "senseless act of violence against two people that were just living their lives in their home."

Buro said the couple worked hard on their dream and had become seasoned sailors. Simplicity “was their home,” he said.

He said the couple’s top priorities were always safety and security, “to make sure everything they did was safe and was going to keep them safe.”

“To have that turn out in a way where something out of their control took that away from them is what’s so horrific about this and so sad, because they were just, this is just something that they’ve always wanted to do, and they did it, and it’s just, it breaks our hearts,” Buro said.
