What It's really like inside a catamaran

catamaran ALTESSE

When people decide they want to charter a yacht for an upcoming vacation, many realize that catamarans are sometimes the better choice. While most people know what they look like on the outside, not many know much about catamaran interiors. We’re here to discuss what the inside of a catamaran is really like.

THEY'RE QUITE SPACIOUS

When looking at a catamaran from the outside, you might think there wouldn’t be nearly enough room inside for people to move around—this is far from the case. All Catamarans feature 3 – 5 cabins, a fully equipped kitchen, indoor lounging area, and indoor & outdoor dining table. The larger the catamaran, the larger all of these spaces become.

While the cabin areas below deck are smaller than your average superyacht, there’s still more than enough room for guests to move around freely. Plus, the deck space is always abundant, giving you plenty of room to enjoy the Caribbean sea.

THEY CONTAIN ALL NECESSITIES

The interior of a catamaran is more than just empty space with a couple of beds. It contains all the necessary amenities you could ever need while at sea. Each cabin below deck has an attached private, full bathroom so that your group doesn’t have to constantly wait on others to finish using the facilities.

Each catamaran has a fully equipped kitchen and indoor & outdoor dining area. If you book a  Caribbean catamaran charter  through Sheer Yachting, the catamaran you choose will come with your own private chef! That way, you can focus more on enjoying your time off and less on cooking meals.

there is storage everywhere

The final thing to know about a catamaran’s interior is that there is plentiful storage space. Depending on your vacation’s length, you will need a lot of room to store your personal items, whether it’s clothing, food, or souvenirs. Catamarans use all the extra space available as storage.

The bottom line is you never have to worry about limited space on a catamaran. They are way more spacious than people assume at first glance. We know that if you decide to rent one for your next trip to the Caribbean, you certainly won’t regret it.

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.

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.

inside of catamaran

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.

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

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

August 30, 2022

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.

‍ 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.

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.

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.

Top-rated boat covers on Amazon

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.

inside of catamaran

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.

Are you a sailing enthusiast who is fascinated by the sleek and efficient design of catamarans? If so, then you’ve come to the right place! In this comprehensive beginner’s guide, we will delve into the key components of a catamaran and unlock the secrets to mastering its various parts. So grab your sailor’s hat and get ready to embark on an exciting journey through the intricate world of catamaran sailing!

The first component that sets a catamaran apart from other sailboats is its dual-hulled structure. Unlike traditional monohull sailboats, which have only one hull, catamarans feature two parallel hulls connected by a deck or bridge. This unique design grants them exceptional stability, speed, and even more interior space for amenities such as cabins and lounging areas.

Now let’s move onto a crucial part of any sailboat – the rigging . The rigging system on a catamaran consists of numerous elements that work harmoniously to control and manipulate the sails . Firstly, there are the masts: tall vertical structures that support the sails. Catamarans typically have two masts placed towards each end of the boat , allowing for efficient distribution of power.

Attached to these masts are various types of sails, including mainsails, jibs or genoas (fore-sails), and spinnakers (used for downwind sailing). The main sail is the largest sail on a catamaran and is hoisted up the mast using halyards – ropes specifically designed for this purpose. Jibs or genoas assist in maneuverability by generating additional power when sailing upwind.

For those seeking exhilarating downwind adventures, spinnakers add an extra element of thrill to your journey! These expansive triangular or bulbous-shaped sails catch wind from behind and propel your catamaran with remarkable swiftness. Learning how to handle these different types of sails will be crucial to seamlessly controlling the boat and maximizing performance on the water.

Next in line are the helm and steering system, responsible for guiding your catamaran ‘s path as it gracefully glides through the waves. The helm, often referred to as the steering wheel , is used to control the rudders located at each hull’s stern. One unique characteristic of catamarans is their tilting tendency caused by wind pressure acting upon the exposed surface area of their broad decks. Therefore, mastering steering techniques, including adjusting sail configurations and keel positions, will help you navigate with finesse and maintain balance.

One particularly innovative feature found in some catamarans is a daggerboard or a centerboard system. Located between the two hulls beneath the waterline, these retractable fins can be individually raised or lowered to vary their depth while sailing. By adjusting these boards according to wind conditions and point of sail , you can minimize resistance, optimize speed, and even prevent lateral drift.

We cannot overlook catamarans’ anchoring systems when discussing their components . Anchors are vital for keeping your vessel secure when moored or stopping for a leisurely swim in crystal-clear waters. Most modern catamarans employ bow rollers integrated at the front end that facilitate effortless anchor deployment and retrieval. With an array of anchor types available — from plows to flukes — it’s essential to understand each one’s characteristics in various seabed environments.

Lastly, let’s not forget about safety equipment onboard! While mastering catamaran parts allows for glorious adventures on calm seas, unforeseen challenges may arise during your sailing odysseys. It’s important always to have safety essentials like life jackets, fire extinguishers, first-aid kits, emergency flares, and navigational tools like GPS systems.

So there you have it – a comprehensive overview of key components necessary for mastering the art of sailing a catamaran! Understanding how each piece of the puzzle fits together and harmonizes uniquely will set you on a path to becoming a skilled catamaran sailor . Whether you’re gliding across tranquil bays or tackling exhilarating rough seas, this guide will equip you with the knowledge and confidence to embark on unforgettable nautical journeys!

First time on a catamaran: what you need to know

  • First time on a catamaran: what you need to know

During your captain training, you'll have learnt how to manoeuvre a monohull sailboat . But what about when you have the opportunity to sail a catamaran?  Find out everything you need to know, including differences from monohulls, important factors to consider, pros and cons, and recommended destinations and catamaran models. If you're new to catamaran sailing, this is the perfect guide for you.

5 reasons to rent a catamaran

What are the main reasons why someone decides to sail on a catamaran? Here are the top benefits of choosing this type of boat.

1. Stability

The double hulls of a catamaran provide exceptional initial stability, allowing it to  remain afloat and stable in rough waters and wind. If you're looking for a smooth and peaceful sailing experience, especially with small children or seasickness-prone individuals, a catamaran is a great option. It's perfect for taking along your grandma or a nervous friend who's never been on a boat before.

YACHTING.COM TIP: Getting seasick is not only a major worry for novice sailors, but also holidaymakers on a boat trip. But it even can affect experienced sailors from time to time. Those with darker humour say it has two phases — in the first phase you become so sick you're afraid you're dying, and in the second, you're afraid you're not going to. The important thing, though, is to understand why it happens and try to prevent it. Although you'll significantly reduce suffering from seasickness on a catamaran, what works best if it does occur? Find out in our guide —  How to cope with seasickness .

A catamaran offers more space than any other boat of similar length. With spacious saloons , plenty of seating and lounging areas , and ample sunbathing spots (such as the netting known as the  trampoline ), you'll never feel cramped. The cabins are roomy and the bathrooms are as big as those in many apartments. People who dislike tight spaces or value their privacy will find a catamaran ideal. On larger models (50+ feet), you'll have so much space, you may have trouble finding each other. Despite its comparable length, a catamaran always feels larger than its monohull counterpart. If you're used to a 50-foot sailboat, try a 45-foot catamaran and you'll still feel like you have more space.

3. Amenities comparable to a hotel room

Not only are the cabins spacious, but they are also comfortable and cosy. They usually come equipped with high-quality bedding, pillows, shelves, reading lamps, and more, making them feel like a proper room. That's why we wrote an article highlighting 9 reasons why a sailing holiday is better than staying at a hotel and it's doubly true with a catamaran.

4. Added extras

Catamarans often come equipped with the latest technology and gadgets. These include solar panels, generator, a seawater desalinator, a modern plotter with GPS, and autopilot . These will make you more self-sufficient at sea without needing the facilities of a marina as often.

5. Shallow draft

The reason why catamarans are so popular with sailors, especially in exotic countries , is the very shallow draft — 0.9 to 1.5 metres, depending on the length of the vessel, which means skippers don't have to concern themselves so much about hitting the seabed. While caution and monitoring charts are still necessary, it provides greater freedom in choosing anchorage spots, allowing you to sail almost right up to the beach and anchor to enjoy the peace and tranquillity.

Catamaran vs. sailboat: the main differences.

Sailors have differing preferences, with some sticking to single-hulled boats and others preferring catamarans. In fact, which is best has been a hot topic since sailing began. This makes understanding the benefits and drawbacks of each hull design essential so you can make your own choice.

1. Rental price

One major drawback of catamarans is their higher cost on the charter market. Single-hull sailboats can be rented for 1,000-2,500 euros per week, while a well-maintained catamaran typically starts at 3,000 euros per week. However, this may not be the case for all models.

YACHTING.COM TIP: If you want to save money on your catamaran charter, we recommend booking it in advance. Check out our  8 reasons why Early Bird deals are the best way to rent a boat .

2. Capacity

The higher cost of catamaran charters is offset by the extra space, comfort, and capacity — it can often hold up to 12 guests comfortably. This results in a per-person cost comparable to sailboats and cheaper than coastal hotels, making them popular for island cruising and party boats. However, for a safe and responsible party experience, we recommend checking out our guide — How to enjoy a party on a boat: 10 tips to keep your crew and your boat safe .

YACHTING.COM TIP: Never exceed the maximum capacity of the boat. And remember that even small children count as crew members.

3. Port charges and marina fees

Keep in mind that having two hulls means a wider boat, leading to higher docking fees . This increased width can take up more space than two smaller sailboats. However, the cost per person can be offset by the fact that more people can be accommodated. 

4. Speed vs. consumption

Catamarans typically feature two high-powered engines , making them faster than similar-sized sailboats. Even without the power of the wind, you can be flying across the waters and with a better fuel efficiency than motor boats.

Catamarans typically have two basic sails: the mainsail and the foresail and operating them follow similar principles as on single-hulled sailboats. Self-tacking jibs can also be used, reducing the work required to trim and manoeuvre the sails. 

For those looking to enhance their sailing experience, a gennaker can often be rented with the catamaran, providing added benefits, especially in light wind conditions. Take a look at our 5 reasons to rent a gennaker .

6. Flybridge

This elevated deck is a common feature on catamarans. Here you'll find the helm station and sometimes additional seating or lounging space. It is a valuable addition that provides extra living space on the boat.

Who is the catamaran suitable for?

Catamarans are the preferred choice for a group of friends wanting a laid-back holiday on the water but are also popular for corporate team-building events  and specialised stays like yoga. As their spacious deck provides a safe play area for children , they are also ideal for multi-family vacations.

YACHTING.COM TIP:  If you are sailing with small children, safety is paramount. So, check out our guidelines for safe boating with kids , our article on how to survive on a boat with kids , the Skipper mom logbook: sailing with a baby and always try to stick to the 4 essential tips for smooth sailing with kids . If you don't have kids or don't want to bring them along, why not take your four-legged friend? Catamarans offer ample space for dogs to run around, and following these 7 tips can help make your pet a true sea dog.

On the other hand, we wouldn't suggest a catamaran to sporty sailors to chase the wind in, as the catamarans for charter aren't intended for racing or regattas. Due to their design, they have limited upwind capabilities (sailing boats can sail up to 30° wind angle, while charter catamarans can only handle up to 50° to 60° wind angle), making them unsuitable for competitive sailing.

YACHTING.COM TIP: If you have doubts about your ability to safely operate the boat, consider hiring a skipper. We can arrange a skipper for you who is knowledgeable about the area and can take care of the navigation for you or teach you any sailing skills you may be lacking. Remember when planning that the skipper will occupy one cabin or berth in the saloon. 

Specifics of sailing on a catamaran

The principles of sailing a catamaran are similar to those of a monohull sailboat, but there are some differences to keep in mind. These may have already been covered in your captain's training course.

Travelling on the engine

A catamaran has two motors , each of which can be controlled separately using its own throttle control. Want to turn on the spot? That's no problem at all with a catamaran — simply add throttle with one motor and reverse with the other. Once you get the hang of this trick, you'll no longer need a bow thruster, although catamarans are sometimes equipped with one. This makes docking your catamaran a breeze compared to single-hulled sailboats.

Travelling on the sails

Sailing varies mainly in what courses you can sail and how strong the winds are. Most charter catamarans perform best on courses at 50 to 60 degrees to the wind. This is a greater angle compared to sailboats. So be prepared to have to adjust your planned route.

If you sail a sailboat too hard, the boat itself will tell you that you've over-steered by heeling. A catamaran won't do that, so you have to be very attentive to when to reef the sails. Usually, you will put in the first reef at a wind speed of 18 to 20 knots and the second reef at 23 to 25 knots.

Catamaran Structure – Bridge Decks and Cross Beams

  • 6 Comments on Catamaran Structure – Bridge Decks and Cross Beams

inside of catamaran

Editor’s Note: Many thanks to Ted Clements of Antares Catamarans and Shane Grover of Seawind Catamarans for patiently answering our questions.

There are a lot of reasons why catamarans are more expensive than monohulls. It’s not just the two hulls. There are many more complicated calculations and structures needed to build the complex shapes.

Building a bridge deck and the structures around a pair of hulls is a lot more difficult to design and build than a single hull, and we’ll explore a little about why.

Part 1: Forces on the Hulls

Load and force calculations on a boat hull isn’t a simple calculation, and even monohulls take a lot of designing to build a shape which performs well and has the strength to hold together at sea. Land vehicles have fairly predictable forces and motion on them, but boats can take forces and stresses in any direction.

inside of catamaran

Waves slam from all directions, boats plunge off waves and get smacked around in chop. Wind forces stress masts and rigging, which applies bending moments and forces to chain plates and the hull. Hulls flex and bend with this motion, and even from tensions applied to the rig.

Elements of drag, hull shape, keel shape and rig design all factor in, whether it’s a heavy, stiff cruising boat or a light, high performance racing machine. Those forces have to be figured, and materials and constructions are made to suit the conditions and situations where the boat will sail.

And that’s just a single hull. When you add a second hull to mix, you add in a whole new set of loads.

inside of catamaran

Bananas and Pencils

To illustrate these additional loads, we’ll do a thought experiment with a couple of household items. You can try it for real if you want to – but you’ll need two bananas and a few pencils.

Start with the bananas laying parallel to each other, then run a single pencil through the midpoint of each banana (the hulls) to connect them. They’re connected, but when you pick it up, what happens? They don’t stay parallel, of course. We need a second pencil or even a third one, to keep them in place.

inside of catamaran

The pencils are the crossbeams you’ll hear about in catamaran construction. If you put two of them through the bananas to connect them about 1/3 of the way from the end of each banana, you’ll get a fairly stable platform (for something made from soft fruit and pencils).

Imagine picking up this banamaran with two crossbeams with one hull in each hand. How can we still move the hulls?

inside of catamaran

First, we can twist one half back and one hand forward, putting lots of force on the crossbeams. To stop this, we could use much stronger beams, and we could put more beams at the ends of the bananas.

If you rotate your hands and the bananas, you demonstrate another type of force on the crossbeams. Pushing the bows or stern together also can move the hulls.

Building the Boat

Now imagine putting weight on the pencils – you’re adding the bridge deck. The mast sits on the bridge deck and creates additional loads and stresses on the crossbeams and hulls.

inside of catamaran

Finally, we add a sailing rig on top of the weight on the pencils. The rig needs support to stay up. On a monohull, stays run to the bow and stern to support the rig. But a catamaran the mast is centered between the hulls. The tension on the rig will provide upward pull on the hull shapes and usually attach to bow crossbeams. So we’re now pushing down on the middle of the bananas while pulling up on the tips.

The challenge to the catamaran builders and designers is to account for all these forces and build a pair of hulls capable of absorbing these loads without breaking or separating the hulls.

Part 2: Crossbeam Design

Catamarans are not new concepts; double hulled sailing canoes were used in Polynesia and Melanesia long before European explorers arrived. One of the first recreational catamarans was designed and built in 1876 by Nathanael Herreshoff and sailed well enough that the New York Yacht Club banned multihulls from racing.

inside of catamaran

Most beams are hollow to save weight in increase strength for the amount of material used. A hollow cylinder or rectangular tube gives more resistance to bending per pound of material than a solid rod of the same weight. There are mathematical explanations beyond both the scope of this article (and my ability to explain), but it’s important to know where the loads on beams are supported to understand this.

Greatly simplified – bending a beam creates compressive loads. The further from the center of the beam, the higher the resistance to compression. A rod will have a narrow diameter and resistance is lower. But if you make a cylinder or square tube from the same amount of metal (or fiberglass) you will have the same cross-sectional area, but the compressive force is applied further from the center of the cylinder.

Think of an I-beam from building construction. The compression is on the sides of the I-Beam, but the part in the middle is mostly to keep the sides in place, not bear the load on the beam in high stress applications.

Original Beams

A close look at these boats shows clear and obvious crossbeams connecting the hulls. Duplex , the early Herreshoff boat, had three clear crossbeams and a cockpit on the aft two between the hulls.

inside of catamaran

Smaller beach and racing cats will have obvious crossbeams, since the decking is usually a stretched piece of canvas or webbing. Other open bridgedeck catamarans, including many home builds, may have actual beams across them holding the hulls in place. And most cats will have some sort of beam across the bows as well.

But when you look at modern bridgedeck catamarans, you notice something strange about the beams. There aren’t any actual “beams” built into the boats.

inside of catamaran

Modern Cruising Cats – There Are No Beams

It’s more you notice something missing about the beams. Modern bridgedeck catamarans don’t generally have actual crossbeams built into them, as if you were glassing a beam or post into the boat. Instead, the construction of the boat is built around a design the provides the mathematical equivalent of a “beam.”

Bear with me. It took a while for me to get my head around this, too.

Picture a box – even a simple shoebox has rigidity to its sides. Yes, you can crush it, but the hollow sided box offers a lot more stiffness than a piece of cardboard on its own. The structure of the beams is in essence a box built between the hulls, with super strong modern laminate materials providing stiffness to take the loads and stresses.

When modern cats are designed, the “crossbeam” is a combination of internal structures built and connected to the bulkheads that create the load bearing capabilities of a hollow beam section. So the “beam” exists mathematically in the designer’s wireframe drawing of the boat, but when it is built, it is not an external beam added to the structure, but rather a set of structures that act like a beam because of their physical design.

inside of catamaran

Developments in materials technology over the last few decades allows for shapes and strengths that couldn’t be built with traditional materials like wood or metal.

Part 3: Building a Bridgedeck

Building the bridgedeck is the key piece of fiberglass catamaran strength. To be able to build a boat which can handle all these twisting and torsion forces, creating that “box” to add the strength, catamaran builders take one of several approaches. All can be effective and meet the design requirements, but there may be other reasons a builder chooses a particular approach.

“Tooling” refers to all the molds needed to shape a fiberglass hull. Tooling can be made from a number of different materials and represents a significant investment for any new production catamaran. Costs can run to many millions for tooling durable enough to build a hundred or more boats without changing design and build tolerances.

inside of catamaran

Molding and tooling to build hulls is a major expense, no matter which approach a builder takes. Building tools and molds can run into millions of dollars in expenses for materials and labor, and molds built for production runs of boats are considerably more expensive than tooling for a one-off or unique design. All of these factors into the decision making behind a build process.

Building a multihull also presents unique challenges compared to building monohulls. Building a single hull can be a fairly linear process – the hull is laid on the mold and built, the inside is fitted out, and decks are attached. While that’s a simplification of the process, it is relatively straight-forward because there is only one hull.

inside of catamaran

For catamarans, the integral bridgedeck structure doesn’t lend itself to a step-wise assembly. The crossbeams and bridgedeck need to be built integrally before the interior and decks are completely finished. For the builder, this means some parts of the boat have to be finished with reduced access to interior sections of the boat. For the designer, the challenge to is to make the boat so the builder can build it efficiently. For production vessels with build runs in the hundreds, cost effectiveness and production efficiency is crucial.

inside of catamaran

Not only does the bridgedeck hold two hulls together against all the twisting and torsion forces we’ve discussed, it also has to carry cargo. It holds the living space in the main saloon, as well as passengers and equipment.

Think back on the shoebox – it has compressive strength from the ends, but any individual side is fairly weak. You can deflect the sides easily. While this is fine on a shoebox, it would be disconcerting if the deck flexed and bounced when you walked across it. The bridgedeck also needs strength from the top and bottom to take this load in the central parts of the boat, away from the “box.” You can’t just make the decks and floors massive, that sacrifices headroom and internal volume. Instead, internal structures and stiff construction materials have to take up the load.

Two Piece Molding

Some builders build two hulls individually. One mold can be used if the hulls are identical, and the hulls joined later in the build process. Like any design and build decision, there are pros and cons for the builder which can affect the cost of the final product. If built correctly, there are no compromises in strength from a one piece mold.

inside of catamaran

For the builder, a one piece mold is much easier to handle. Any hull built on a mold will have to be removed from the mold once the hull is laid, and a single mold is smaller, lighter, and narrower. Breaking a hull out of a mold is a complex process, and may involve cranes and heavy equipment to support the hull as it comes of the mold and to protect the tooling from damage. To remove a hull, you need space to lift the mold and to get heavy equipment around the tooling. And you’ve got to put the molds some place when it’s done.

inside of catamaran

Connecting two hulls precisely once they’re molded is a more complex task. Unidirectional fibers bond key structures to bulkheads to build the support “box” making up the crossbeams. Although a one piece mold will give an inherently stronger single-material connection between the hulls, more than sufficient strength can be built in with advanced fiber and resin choices (such as carbon fiber and epoxy) when then build the deck connection.

One Piece Molding

Most production catamaran builders have moved to one piece molding. A single tool is built to lay up both hulls and the bottom of the bridgedeck connection in a single large piece. The fundamental strength of the build is higher, allowing for less expensive materials to get the same strength.

“One piece” is a slight misnomer, as the top of the hulls and decking is built in a second mold which is laid over the hulls and bonded along the joint near the top of the hull molds. The loads on a join between the bottom hull and top deck are considerably lower than those on the bridgedeck. There’s no real twisting and torsion on that part of the boat relative to the join between the hulls, so it can be laminated without the same concerns as building between the hulls. ( Editor’s Note: Some builders mold the bridgedeck and inboard half of the hulls together and then mold on the outboard halves of the hulls and deck on top. There is a seam running stem to stern centerline along the bottom of each hull with this technique. )

inside of catamaran

There are a number of production and build advantages to this approach. Though the tooling is larger, more expensive and awkward, the lay up process incorporates the core hull joins in the initial build. You don’t have to line anything up and glass it in place when your hulls and deck are built connected. There isn’t need for as much material buildup to shore up the “box” since it’s part of the integral build.

Fitting the interior joinery and finish is more challenging, since the crossbeams and related components must be built early in the process. Extra care and planning in the design process can make this more efficient, but access to internal areas of the hull can be difficult during the build.

inside of catamaran

Alternative Materials – Wood and Metal

Composite construction – fibers and resin – lets builders make nearly any shape. Fiberglass has allowed for the wide range of affordable to high end production catamarans available today. Stronger fibers and better resins have only expanded the possibilities for light, fast, and strong boats.

inside of catamaran

Wood is rarely used for structural elements in modern production catamarans. It can be heavy, and it doesn’t lend itself to the complex molded shapes designers demand for optimal strength and seaworthiness. Plywood may be used for stiffening in places, and balsa cored decks may still be found. But mostly in older boats, home builds, and kit boats.

inside of catamaran

Metal construction has its own problems, and very few catamarans are built from metals. Curved shapes are difficult with metals; bending a smooth radius into a flat sheet without bending it, then welding it into place requires time and skill. And weight will be a problem. On the whole, fiberglass is a better solution for a light, strong catamaran.

inside of catamaran

Conclusion: Tying it Together

This overview only touches on some of the challenges multihull builders face, which monohull builders do not. But what does it mean for you when you’re looking at catamarans to buy? All the fiberglass build techniques will result in a strong boat if built properly. There may be differences in the amount of materials used, and choices for resins and fibers, but the boat should be evaluated as a whole.

It’s good to understand how your boat is built, and to be aware of some of the strengths and limitations of each build technique. But no build technique is inherently better or worse than the other – no matter how your next boat is built, the designer and builder will ensure the build is up to the task.

Proof read much? But the no build technique is inherently better or worse than the other… Good article spoilt by miss spellings and errors.

I corrected the extra “the” you mention in that sentence. I do not see other errors. We do our best and thank you for reading and commenting.

Great article. Very informative for us non-technical types. Great use of graphics and photos to explain the various torsion forces and different build methods. What is the purpose of the wing-like, rear spoiler-looking feature that you sometimes see spanning across the back of the deck/bridge and sometimes connecting the two hulls?

It doesn’t actually connect the hulls, it rests on them. In the good old days this was named a “RADAR Arch” and was used to mount the RADAR antenna and dinghy davits.

Over the last 20 years this stern “ARCH” became a very convenient spot to mount RADAR, solar panels and it is in this role it serves very well while also handling various antennas and of course, the dinghy.

Thanks for the article, great stuff, very informative and useful info. Kudos

I’m actually researching and trying to figure out how to build my own catamaran. But information is very hard to find.

New catamarans: 2021’s most exciting launches

Yachting World

  • April 7, 2021

Fast cruising is the theme this year, say Toby Hodges and Sam Fortescue, who look at some of 2021's exciting new multihull launches

inside of catamaran

2021 looks set to be a bumper year for new catamarans as the trend for fast cruising yachts, which deliver plenty if living space continues. This year there are set to be several new catamarans on the market, here’s our selection of those about which we are most excited.

A group of wild enthusiasts in the landlocked Czech Republic are the force behind the new IC36 from Independent Catamaran. The debut model is a fully race-tuned cat that aims to appeal to speed freaks as well as performance cruisers. Oh, and it unbolts to fit inside a shipping container or on a trailer!

Perhaps closer in design terms to the Extreme 40 than a traditional cat, the IC36 has super narrow hulls, high displacement bows and an optional rotating carbon rig with composite stays.

A sporty-looking carbon beam braces the bows and doubles as a bowsprit for asymmetric sails. Deep daggerboards help windward performance, and there’s a racy dual carbon tiller providing direct rudder control.

“The first time I saw it, I just felt like it was from one of Jules Verne’s adventures,” says co-founder Jaromír Popek.

The boat has been optimised for electric propulsion with twin 6kW Oceanvolt saildrives and up to 15kWh of lithium-ion batteries giving a range of a couple of hours. Powerful hydrogeneration under sail keeps batteries topped up. For longer spells at anchor , there is also a decent 1.15kW array of Solbian solar panel s which folds away when not required.

As much fun as this boat should be to sail in its Raw racing variant, it is also available with more creature comforts.

The Pacer model has a coachroof, cockpit tent, more storage and cooking and freshwater systems. It can accommodate a reported eight people in the hulls, with a fridge and two-burner hob to port and a shower/heads to starboard. Or you can opt for a fridge and hob in the folding cockpit table.

Construction is in epoxy-glass composite with local Kevlar reinforcement and foam core, helping to keep weight down to less than 3 tonnes (key for trailering). And there are three buoyancy chambers in each hull, which underpin the claim that the boat is unsinkable.

For all the variants, the light weight and high-performance rig means you can sail in a breath of wind. In a blow, the sky should be the limit. Expect reaching speeds of 20 knots plus, particularly if you take the high-modulus carbon wing mast from Pauger.

Specifications:

LOA: 11.00m / 36ft 1in Beam: 6.20m / 20ft 4in Draught: 0.85-2.00m / 2ft 9in-6ft 7in Displacement (light): 2,500kg / 5,512lb Price ex VAT: €295,000 (for RAW) Builder: www.independentcatamaran.com

This new launch from the world’s number one catamaran brand is the largest in the range of ‘regular’ boats, before entering the more luxurious world of the Lagoon 65.

It has been drawn by VPLP and Patrick le Quement, whose design nous has done much to make cats more mainstream. Many of the features, therefore, will be familiar from the smaller boats.

However, that extra length creates more volume below, so the Lagoon 55 can be arranged with up to six true double cabins with ensuite heads. “It’s the first time we have six cabins of the same size and function and a larger flybridge,” explains products developments manager Martina Torrini during a premiere virtual tour of the first model to launch in March.

Another first is the curving steps up from the transom skirt to the aft deck, dubbed ‘the stairway to heaven’. “The surfaces of the transom can be used differently,” adds Torrini. “Not just a way to access the boat, they become in themselves a living area.” This feature extends the size of the cockpit to 25m2, and even offers a plancha grill.

There’s more social space on the huge flybridge (with fridge and bar) and a movable sunpad on the forward part of the coachroof. The boat also features Lagoon’s first ever dedicated forward cockpit, connected to the saloon by a drop-down window.

A 107m2 fat-head main provides grunt, but is coupled with a self-tacking jib. As with all Lagoons, the emphasis is on comfort and ease of use rather than speed and windward pointing ability.

LOA: 16.56m / 54ft 4in Beam: 9.00m / 29ft 6in Draught: 1.55m / 5ft 1in Displacement: 26,500kg / 58,433lb Price: €tbc Builder: www.cata-lagoon.com

Fountaine Pajot Samana 59

Replacing the five-year-old Ipanema 58, this luxurious 59-footer integrates many of the new design features of the 45, which boasted longer, wider hulls that nevertheless showed 10% less drag. Chief among the new attractions is an enlarged cockpit, forward lounge and flybridge, for more socialising space.

“We wanted to emphasise her identity by optimising her interior and exterior spaces to make this 59ft catamaran the equivalent of a larger yacht,” explains designer Olivier Racoupeau.

“Whether it’s the flybridge, the cockpit or the saloon, we’ve worked hard to find harmony between all the living spaces on board, to gain every millimetre inside and outside.”

There’s a door forward out of the saloon, and the option of a hydraulic bathing platform, which doubles up for tender storage. Up to six cabins are offered, and the rare option of putting the galley up in the saloon or down to port. Hull number one is joining the World ARC .

Meanwhile, a new 51 is tipped for launch in 2022, which will focus on sustainability and have 2kW of flush solar panels built into the flybridge.

LOA: 18.21m / 59ft 9in Beam: 9.46m / 31ft 1in Draught: 1.40m / 4ft 7in Displacement: 25,500kg / 56,217lb Price ex VAT: €1,302,900 Builder: www.catamarans-fountaine-pajot.com

The new 42 replaces the Leopard 40, and it draws on the latest design thinking from the larger boats in the range. Like the award-winning Leopard 50, it has continuous hull windows, a hardtop, and contrasting coachroof accents. But it also goes further, with plumb bows and long horizontal chines.

That lounging space on the coachroof adds 65% to the exterior entertainment area. “By integrating the geometry of the lounge into the GRP hardtop, we were able to achieve a lightweight area that added less weight to the boat than one average sized crewmember,” explains Michael Robertson, chief designer at builder Robertson & Caine. It has been cleverly engineered so as not to steal headroom from the cockpit.

In contrast to many modern cats, the Leopard 42 makes a virtue of the separate cockpit and saloon, whose seating is focused on the forward galley. There is lots of glazing and a full-height door out onto the foredeck. Every cabin has a third more floor space and twice the glazed area of the old Leopard 40. Each has an island berth and its own heads with shower.

But it’s not all about space. “Performance potential remains one of the top priorities,” says naval architect Alex Simonis of Simonis-Voogd Yacht Design. “We spend a lot of time refining the rig geometry and the sail layout to boost the efficiency of the rig plan. At the same time, the ongoing refinement in hull and appendage design allows us to create a yacht with better sea motion and more agility.

LOA: 12.67m 41ft 7in Beam: 7.04m 23ft 1in Draught: 1.40m 4ft 7in Displacement: 12,460kg 27,469lb Price ex VAT: €399,000 Builder: www.leopardcatamarans.com

The new entry-level yacht from France’s Neel Trimarans is designed to bring the world of three hulls to a new clientele.

Building on the success of the larger Neel 47 and Neel 51, the 43 takes the fight to the catamaran, with a big superstructure that includes two double cabins as well as a galley and saloon.

There’s a further double cabin forward in the central nacelle, and cosy singles in either bow. A sliding door and window allows the saloon and the cockpit seating areas to be socially connected, although they remain two very different spaces.

The bulkhead helmstation to starboard has commanding views out over the huge coachroof. From the drawings, this appears to allow a tight sheeting angle for the genoa, but brings the mainsheet, which is fastened to the transom, close to the davits and skirt of the central hull.

The main is square-topped with two full battens and there is also a high-performance carbon spar option.

Though the lay-up is in standard foam-cored glassfibre, Neel says it is leaning towards more environmentally friendly construction. Interior joinery is from sustainable Alpi wood and recyclable material.

LOA: 13.11m / 43ft 0in Beam: 7.50m / 24ft 7in Draught: 1.50m / 4ft 11in Displacement: 9,000kg /19,841lb Price ex VAT: €329,800 Builder: www.neel-trimarans.com

Marsaudon Composites has quietly built an enthusiastic following for its TS42 and TS50 catamarans since the smaller boat was launched six years ago.

That these have been the first boats to cross the Atlantic in the last two ARC s has also done its reputation no harm.

The yard is based at Lorient La Base, at the heart of the French offshore racing scene, so it’s perhaps no surprise these designs are lightweight and offer plenty of performance.

The direct tiller steering, which gives a responsive feel to the helm, is an example of the thinking that sets these boats apart from other multihulls and makes them sought after models. Yet they also have enough space both on deck and below to offer very comfortable living.

A 57-footer from the board of Marc Lombard will be the third design to join the stable. It shares the same hallmarks as the existing models, although a wheel steering option will also be offered.

In suitable conditions this is a cruising yacht that can be expected to hit speeds of well over 20 knots.

The hull shape is clearly a progression from the earlier models, while following the same light displacement principles with fine hull shapes. Lombard drew a new shape for the bows to increase efficiency and reduce the tendency for bow-down trim. He told us: “The bows are shaped so that, when the boat is powered up and starts to heel, the lee bow will generate extra lift to push the bow up.”

The additional size makes the interior spaces of this boat significantly larger than those of the 50-footer, especially in the hulls. Much thought has also gone into ergonomics and weight saving, stripping out and simplifying anything that is not essential. CEO Damien Cailliau likes to draw on a quote from Colin Chapman, founder of Lotus Cars: “Simplify, then add lightness.”

As an example, there are no hull linings, which saves weight and complication, but requires extremely neat moulding. “A core competency of Marsaudon Composites is that we produce excellent mouldings,” says Cailliau, “so we don’t need to hide our work.”

Seawind 1260: Lightweight catamaran making waves on both sides of the Atlantic

The Seawind 1260 has been well received in the States, where the brand has a strong following, but these multihulls…

As a low volume builder – only 28 of the smaller boats have been built in total – Marsaudon Composites can offer semi-custom interior arrangements, providing they don’t add unnecessary weight. The boat can also be built with varying amounts of carbon to reduce displacement further.

At the same time as announcing this design Marsaudon launched a rebranding of the range, which will now be known as Ocean Rider Catamarans (or ORC). The new name is a better fit with the qualities with which owners identify than the Très Simple concept that led to the original TS designation.

To underscore the difference between these boats and the majority of catamarans in this size range a tiller has been incorporated in the logo.

Tooling for the ORC 57 is under construction and the first boat is scheduled to be unveiled in September 2021.

Current Marine CM46 & CM52

The founder of RS Sailing , Martin Wadhams, is a racing sailor who now spends more and more time cruising.

Martin and his wife, Amanda, enjoy sailing fast boats and have spent some time looking to upgrade from their Pogo 12.50 to a multihull. Their search for a true performance cruising catamaran – and one that wouldn’t cost seven figures – turned out few viable options.

Australian-based designer Jeff Shionning put them onto some fresh designs he has done for Current Marine, a new South African brand formed from an experienced team of composites experts at Knysna, between Cape Town and Port Elizabeth on the south coast.

It has been set up to build the new CM46 and CM52 in low-volume semi-custom production. On visiting the yard a year ago, Wadhams was impressed enough with the high tech builds to order the second CM46.

He reports that the joinery is all laminated in, there is plenty of opportunity for layout customisation (in three or four cabins) and, owing to the lower labour costs in South Africa, pricing is keen.

Shionning’s CM designs are lightweight, efficient catamarans that should be able to sail well in light breeze and outrun weather systems in the open ocean.

Key features include daggerboards, fine bows, centralised weight of engines and tanks, and high bridgedeck clearance. The rig is also positioned amidships for optimum weight centralisation, while also helping to create a large foretriangle for flying a range of furling headsails. Aluminium or carbon spars and diesel or hybrid propulsion are offered.

Wadhams says there is good stowage space and payload capacity for comfortable liveaboard cruising. “They’re built using post-cured epoxy, carbon, E-Glass and PVC foam-cored laminates – a level above mainstream brands,” he insists. “This brings the construction found in a few larger, high-end boats into smaller-size catamarans.” The first CM46 is a full carbon racing version destined for an Auckland-based owner and is due to launch early 2021. The second boat (for Wadhams) has a more cruising-oriented spec.

Catamarans: Advantages and the Downsides of a double-hulled

398A0042

What are the advantages and the downsides of a catamaran?

Let’s talk boats – the classic monohull vs. the cool catamaran. Picture this: the monohull’s got one hull, a bit like a lone ranger with a hefty keel. But the catamaran? It’s like the dynamic duo, balancing on two hulls, with sails right in the middle. Easy peasy!

Why do folks go wild for catamarans, you ask? Well, size and stability steal the show. Catamarans boast more room above and below decks, making ’em a hit with vacationers. Plus, with two hulls, they stay as level as a boss, no wild tilts here! It’s a breezier sail, no wrestling with gravity.

Catamarans are the rockstars of the boating world! These double-hulled wonders bring the party to the high seas. Picture this: more space, less rocking, and a smoother ride – it’s like boating in luxury! With their wide stance, they’re as stable as a yoga guru on one foot. Plus, they’ve got speed that’ll make your hair stand on end! And let’s not forget the views – panoramic perfection from every angle. Catamarans are the ultimate waterborne playgrounds, delivering thrills, spills, and chill vibes all in one sleek package. So hop aboard and let the good times roll, because life on a catamaran is a non-stop fiesta!

And get this – they’re not as picky about water depth, so you can explore shallow spots that monohulls can only dream of. At anchor, you won’t be rockin’ and rollin’ all night. Oh, and did we mention the privacy? The two hulls keep things nice and separate. So, when it comes to boats, it’s safe to say, cats have got it all!

But since not everything is all good, below we have created a list of pros and cons of having a catamaran.

ADVANTAGES | Unlocking the Advantages of Catamaran Ownership

Spacious & stable.

Catamarans are very spacious and stable just like a houseboat, so they make great vessels for a vacation or even for those who want to live on a boat. Catamarans are characterized by their dual-hull design, which provides them with several distinct advantages in terms of space and stability.

  • Spaciousness: Catamarans generally offer more interior and deck space compared to monohull boats of similar length. This is because the two hulls create a wider platform, allowing for larger cabins, living areas, and deck spaces. This extra room is particularly noticeable in the main living areas like salons, kitchens, and cabins.
  • Stability: The wide hulls of a catamaran provide excellent stability on the water. They are less prone to heeling (leaning to one side) compared to monohull boats. This makes catamarans a popular choice for those who may be prone to seasickness or for those who simply prefer a more stable ride.
  • Reduced Rolling: Catamarans are less likely to experience the rolling motion that is common on monohull boats. This is because the two hulls work independently, reducing the side-to-side motion that can be uncomfortable for some passengers.
  • Shallow Draft: Catamarans often have a shallower draft compared to monohulls of similar size. This allows them to access shallower anchorages and coastal areas that may be off-limits to deeper-draft boats.
  • Privacy: The dual-hull design of catamarans often allows for more private sleeping arrangements. Cabins are typically located in separate hulls, providing more individual space and privacy for guests.
  • Entertaining Space: The wide deck area between the hulls, known as the trampoline, offers a fantastic space for socializing, sunbathing, or enjoying the scenery. It’s a unique feature that many catamaran enthusiasts appreciate.

Safety! Catamarans are safe for cruising and even safe for those adventurous people who want to cross the ocean. In fact, catamarans are often much safer than similarly sized yachts. Safety comes from increased motion comfort, great stability, speed, and excess buoyancy due to lack of ballast. Catamarans are good even in rough water.

  • Escape Routes : Catamarans typically have multiple exit points, allowing for quicker and easier evacuation in case of an emergency.
  • Redundancy : With two engines, two rudders, and often two separate electrical systems, catamarans have built-in redundancy. If one engine or system encounters a problem, the other can usually compensate.
  • Bouyancy : In the event of hull damage, catamarans tend to stay afloat due to the inherent buoyancy of their multiple hulls. This provides more time for passengers and crew to take necessary safety measures.
  • Visibility : The elevated helm positions on many catamarans provide excellent visibility for the captain, allowing them to see potential hazards or other vessels more easily.

Inside and outside steer

Many catamarans are designed with both inside and outside steering options. This provides flexibility for the captain to choose the most suitable steering position depending on weather conditions, visibility, and personal preference. So, captains have the option to steer from the inside during bad weather or when the water conditions are less than ideal. Keep in mind that the specific configuration may vary depending on the make and model of the catamaran

  • Inside Steering : Catamarans typically have an inside helm station located in the main salon or cabin. This allows the captain to steer and navigate the boat from the comfort of an enclosed space, protected from the elements. Inside steering is particularly advantageous in adverse weather conditions or when additional shelter is needed.
  • Outside Steering : Catamarans also have an outside helm station usually located on the deck, often near the aft (rear) of the boat. This provides a more open and unobstructed view of the surroundings, which can be beneficial for maneuvering in tight spaces, close-quarters situations, or when the weather is favorable.

Withstand high winds

If you are worried about windy weather, catamarans are also known for their excellent ability to withstand high winds. Catamarans are generally designed to withstand high winds quite well due to their inherent stability and aerodynamic profile. While catamarans are designed to handle high winds, it’s important for any boat, including catamarans, to be operated with caution in extreme weather conditions. The experience and skill of the captain, as well as adhering to proper safety protocols, are crucial for ensuring a safe boating experience in challenging weather. Additionally, all boats should be equipped with appropriate safety gear, including life jackets, navigation lights, and communication devices.

Here are a few reasons why catamarans are well-suited for handling high winds:

  • Wide Beam : Catamarans have a wide beam (the distance between the two hulls), which provides a stable platform. This wide stance helps distribute the forces of the wind, reducing the likelihood of capsizing or heeling over.
  • Low Center of Gravity : The weight of a catamaran is distributed lower in the water compared to a monohull boat. This low center of gravity contributes to stability in strong winds.
  • Reduced Heeling : Catamarans are less prone to heeling (leaning to one side) compared to monohull boats. This means they maintain a more level position in high winds, providing a more comfortable and secure ride for passengers.
  • Aerodynamic Design : Catamarans have a sleek and aerodynamic profile, which allows them to slice through the wind more efficiently than some other types of boats. This helps reduce the resistance to strong winds.
  • Structural Integrity : Well-built catamarans are constructed with strong and durable materials. This ensures that they can handle the stresses and pressures associated with high winds.

Catamarans rely on the buoyancy of their two hulls as opposed to yachts, that only have a single hull. They can be in shallower water without losing stability or the ability to navigate. Yachts rely on a deeper draft to ensure the performance of the boat.

Less fuel? Yes, catamarans have less resistance to get on plane, which results in fuel economy. Their speed rises steadily and there is little to no spikes in fuel consumption. Catamarans are generally more fuel-efficient than similar-sized monohull boats due to their design characteristics. Here are some reasons why catamarans tend to be more fuel-efficient:

  • Reduced Drag : The hull design of a catamaran creates less water resistance compared to a monohull. This means that it requires less power to achieve and maintain a given speed, resulting in lower fuel consumption.
  • Lighter Weight : Catamarans are often lighter than monohulls of similar size. This means they require less power to move through the water, which in turn leads to improved fuel efficiency.
  • Multiple Engines : Many catamarans are equipped with twin engines, which allows for better maneuverability and fuel efficiency. The ability to operate on a single engine at lower speeds can save fuel compared to running a larger single engine at higher speeds.
  • Sail Option : Some catamarans are designed with sails in addition to engines. When conditions allow, using sails can significantly reduce fuel consumption, as the wind provides propulsion.
  • Diesel-Electric Hybrid Systems : Some modern catamarans are equipped with advanced propulsion systems, including diesel-electric hybrids. These systems can optimize fuel consumption by efficiently managing power sources.
  • Shallower Draft : Catamarans often have a shallower draft compared to monohulls, which allows them to access more fuel-efficient routes, such as shallower anchorages and coastal areas.

DISADVANTAGES | The Drawbacks of Catamaran Ownership

Stability for some is a no go.

For those that are into sailing sports, Catamaran yachts are not the most suitable. Why? Well, for the same reasons that make them great houseboats, stability. For that reason, half of the yachtsmen would never buy them. If there is too much sail exposed to the wind and the force of the wind is greater than the weight of the boat … wow… there it goes. The boat will literally trip sideways over the downwind side hull, capsizing. This can happen to small and large cats alike.

  • Performance in Light Winds : Catamarans, especially those with a wider beam, may not perform as well in very light winds compared to monohulls. The reduced heeling and narrow hulls of monohulls can sometimes give them an edge in extremely light conditions.
  • Difficulty in Heeling for Sailing Enthusiasts : Sailing purists who enjoy the challenge of heeling and working with the natural forces of the wind may find catamarans less engaging, as they tend to remain level even under sail.

The cost of keeping a catamaran in a marina can vary widely depending on factors such as location, marina facilities, boat size, and amenities offered. Marina fees are often based on the length of the boat. Catamarans, which tend to be wider than monohulls of similar length, may be charged a higher fee to accommodate their beam. Some yacht clubs may not even be suitable for catamarans.

Docking and Close Quarters Maneuvering

Docking a catamaran can present different challenges compared to docking a monohull due to its wider beam and dual-hull configuration. Catamarans often have twin engines and two separate hulls, which can make tight maneuvering in marinas or docking in narrow spaces a bit more challenging compared to monohulls.

  • Width : Catamarans are typically wider than monohull boats of similar length. This can make it more challenging to navigate tight spaces in marinas or docking areas.
  • Windage : Catamarans have a larger surface area exposed to the wind, which can make them more susceptible to being pushed off course during docking. Captains need to be aware of wind direction and strength when maneuvering a catamaran.
  • Propeller Configuration : Catamarans often have twin engines, which can provide more precise control during docking. However, it also means the captain needs to be skilled at maneuvering with dual propulsion.
  • Depth Perception : The separation of the hulls can make it harder to judge distances and angles when approaching a dock or slip. Captains may need to rely on experience and practice to develop a good sense of depth perception.
  • Visibility : The position of the helm station on a catamaran can vary, but it’s typically higher and more centralized compared to monohulls. This can provide better visibility, but it may still take some adjustment for captains who are used to the lower vantage point of monohull boats.
  • Tight Quarters : Maneuvering a catamaran in a crowded marina or in narrow waterways can be more challenging due to its width. Captains may need to plan their approach carefully and consider factors like current, wind, and other vessels.

The services can also be more expensive. Remember, there are two engines instead of just one. The cost of servicing a catamaran can vary depending on factors such as the specific make and model, age, size, and the complexity of its systems. In general, there are a few considerations that may affect the overall cost of servicing a catamaran:

  • Twin Engines : Many catamarans have twin engines, which means there are two engines to maintain and service. This can potentially increase the cost of engine maintenance compared to a monohull with a single engine.
  • Additional Systems : Catamarans may have additional systems and equipment, such as two steering systems, two electrical systems, and more plumbing. This can lead to potentially higher maintenance costs compared to monohulls.
  • Specialized Knowledge : Some maintenance tasks for catamarans require specialized knowledge or expertise due to their unique design. This may result in higher labor costs or the need to hire technicians with specific catamaran experience.
  • Sail Handling : If the catamaran is equipped with sails, maintaining and servicing the rigging, sails, and associated equipment may add to the overall cost.
  • Anti-Fouling and Bottom Paint : Due to their wider beam, catamarans often have more hull surface area to cover with anti-fouling paint. This can lead to higher material costs for bottom maintenance.
  • Insurance and Documentation : Insurance premiums for catamarans may be higher due to their higher value and unique characteristics. Additionally, documentation and registration fees may vary depending on the type of vessel.

It’s important to note that these potential drawbacks are subjective and may not be significant concerns for all sailors or boat owners. Ultimately, the choice between a catamaran and a monohull should be based on individual preferences, priorities, and the intended use of the vessel.

Shape & Resistance

A boat's hull shape and the distribution of volume are key factors in determining how it will behave in varying wind and load conditions. The underwater characteristics of a vessel are responsible for allowing a multihull and its cargo to travel through the water. The faster and more effortlessly the twin hulls can displace the surrounding fluid, the less resistance and more efficient a catamaran will be.

Typically modern catamaran designs have sharp bows to drive the vessel through the seas with as little wave making as possible. High freeboard assures a dry ride. Ample buoyancy helps keep the stems out of the water and spray to a minimum. Elliptical sections make up the first third of the hull, providing an easy entry in the water and some means to resist leeway. Towards the middle of the boat, gradually flattening out towards the stern, the sections become semicircular to help distribute buoyancy. These portions help carry payload and facilitate the hull lifting at speed. Basically, the majority of all cruising catamarans share these same underwater features.

Decades ago very seakindly, double-ended hull shapes were the norm as found in the thousands of Wharram catamarans. They were easy to construct, relatively slippery, and provided ample freeboard. Unfortunately they could not carry a lot of cruising gear, had cramped accommodations and were not the best windward performers. Their sharp V-sectioned hulls and rudders were their only means of resisting leeway as they had no leeway preventing devices. Similarly, the narrow asymmetrical type hull, such as found in the Hobie 16 beach catamaran, is hardly used in today's cruising multihull. The idea was to keep the underwater appendage to a minimum and eliminate any keels or daggerboards.

In contrast, the modern catamaran benefits from tank testing and computer-aided design. Composite molding technology allows for infinite shapes and each designer or manufacturer can now realize his idea of the perfect hull shape. Today's mini keels and daggerboards keep the cat hard on the wind and rival the weatherliness of monohull racers.

Drag on the hulls is the main deterrent to speed and has many components. We have to distinguish between water and air drag. Water-induced resistance can be further broken down into drag caused by wetted surface and wave making. Wetted surface, which is the frictional resistance the hulls experience when they are passing through the water, is the main cause of resistance at low speed. Wave making becomes more important as boat speed exceeds hull speed , or 1.34 x square root of the waterline length. Wave making resistance is not as easy to analyze and is more complex than drag caused by wetted surface; it is primarily a function of weight and, secondarily, of hull shape.

Catamarans

Pitch is another form of drag which can slow the boat down. This unwanted phenomenon is directly related to the buoyancy of the extremities and weight distribution. Wave-making resistance caused by the boat's constant plunging will slow a multihull, especially since it has less momentum to drive it through waves as compared to a single-hulled vessel. In addition the airflow over the sails will be disturbed by a constant change of attitude, further hindering efficient progress. Pitching can also be caused by placing items that are too heavy into the extreme ends of the multihull. In addition, various design- and construction-related issues can cause this problem, such as bridge decks extending too far forward of the mast and a high, heavy rig. Solid decking instead of trampoline nets, and/or large protrusions, which strangely some manufacturers claim break up waves, can also cause a hobby-horsing effect. Not only can this result in more wave-making drag than desired, but can seriously tire the crew. Any structure ahead of the mast can cause major slamming when having to face steep seas. Although many cruising catamarans, such as the Prouts, have been built with large bridgedeck structures extending forward to the bows, it is my opinion that an open trampoline, which poses no resistance to wind and seas, is imperative on a good cruising cat.

above High freeboard and angled-out hulls are trademark features of this capable Catana 521. Much thinking has gone into the hull shape of this catamaran, yet the pronounced step running along the inside of the vessel might create some wave slap in some conditions, a typical example of a compromise between space and performance.

C. Typical performance catamaran cruiser

D. Racing multihull, with almost no wave making resistance below A popular French catamaran, as photographed out of the water at the Paris Boat Show . Note that there are barely several inches of clearance between the bridgedeck and waterline. The pronounced forward knuckle of the nacelle is claimed to break up waves. In my mind however, there is very little that can resist the continued impact of seas, and any conflict between the wingdeck and waves should be avoided.

Readers' Questions

What is a characteristic of a catamaran hull?
A characteristic of a catamaran hull is that it has two parallel hulls, which provide greater stability than a monohull vessel and help reduce roll, pitch and yaw. Catamarans also generally require less power to achieve a given speed than a monohull and provide improved handling characteristics in open water.
What may cause hull on catamaran to bend?
Hull flexing on catamarans may be caused by several factors, such as high winds, strong waves, heavy loads, and improper loading. Poorly designed or constructed hulls can also be more vulnerable to flexing.
How to construct catermaran hull show pictures?
Unfortunately, it is not possible to construct a catamaran hull with pictures alone. A catamaran hull is a complex structure that requires precise measurements and calculations in order to ensure that it is structurally sound and performs optimally when in the water. If you would like to learn more about constructing a catamaran hull, you should refer to resources such as books, websites, and experienced boat builders who can provide you with detailed instructions.
How far should a catamaran bridge be of the water?
The height of a catamaran bridge will depend on the size and type of the catamaran. Generally, a bridge should be slightly above the water line, typically between 6 and 12 inches.
How to get catamaran hull resistance?
Catamaran hull resistance is determined by a number of factors, such as the shape of the hull, length and beam dimensions, wetted surface area, type of appendages, and underwater profile. To determine the resistance, the hull needs to be tested in a towing tank or in the open water. The resistance coefficients obtained by testing can then be used to calculate the total resistance of the catamaran hull.
