The 8 Main Characteristics of a Catamaran Hull

Posted on May 28, 2022

Ever wonder why your catamaran ride is so much smoother than other boats, including yachts? Why don’t I get as oozy as when I’m on other vessels, even when the water is choppy?

It’s all about the hull, my fellow water enthusiasts. Not just one but two hulls, positioned in such a way as to give us the most perfect ride we can get on the ocean, without us having to grow fins.

Catamarans have a wide beam, instead of a ballasted keel like a monohull vessel, which provides its steadiness. It has a more shallow draft and smaller displacement than a monohull with a similar length. Its hull offers stability, more space, privacy, no heeling, lower hydrodynamic resistance, and more.

Now that you’ve gotten the gist of it, let’s look in-depth at the hull characteristics.

1. Lower Hydrodynamic Resistance

Hydrodynamic resistance of the combined two hulls is usually lower than equivalent monohulls, needing less power from the sails or the engines. A catamaran’s broader posture on the water can decrease the feeling. 

It also lessens the motions caused by waves, which can also produce smaller wakes than on a single-hulled vessel. 

A cat’s hulls have a less wetted surface area, which means they burn less fuel. The boat may be propelled by one engine in mild winds.

2. Reduced Heeling

The term “heeling” refers to the tendency of a sailboat to lean to one side due to the force of the wind on its sails. The boat is oriented so that the wind hits the sails at an angle and pushes them to one side of the boat, propelling the boat.

Catamarans are the safest way to navigate the oceans because they have no heel angle. Cruising catamarans are safer than monohulls for their crew because they offer better protection and a no-heel environment. 

As a result, the crew will be less exposed, make fewer mistakes due to exhaustion, and arrive at their destination more rested.

3. Less Displacement

Boats that employ buoyancy to support their weight are referred to as displacement hulls. To provide its name, it is partially immersed and moves by causing water to be dislodged. 

Its weight is equal to the amount of water it dispenses. In stormy water, it maintains its sturdiness. As a result, cruisers and sailboats alike frequently make use of this design.

4. Stability 

In place to evade capsizing as well as heeling, the catamaran depends on hull stability, while hull stability depends on buoyancy and beam. About half of a typical cruising catamaran’s length is its beam. 

Say, for example, that the boat was 50 feet in length, the beam might be about 25 feet broad so that you could maintain the balance between heel and righting moment.

On a cat, passengers who are prone to motion sickness will be far less affected by the impacts of motion than they would be on a monohull. The cook’s task is made much easier while traveling and at anchor because of the cat’s extra stability. When compared to monohulls, catamarans have less rock and roll.

Once you’ve decided to sail, you won’t have to worry about scrambling to stow things or securing them with bungee cords. Relatively rough seas have little effect on most of the ship’s equipment.

5. A Bridgedeck Connects Them

You can’t ignore this reality! Bridgedeck clearance, or the gap between the water and the bridge deck, is an important factor in a catamaran’s safety and reliability. Ocean waves have room to flow between the hulls thanks to the bridge deck clearance. 

Our catamaran’s hulls create waves that converge underneath the bridge deck, requiring a larger buffer for the bridge.

If you don’t have enough clearance, your catamaran will be pounded by the waves. 

In addition to slowing your catamaran down by 3 to 4 knots, rough seas can also put your guests’ health and safety at risk, as well as inflict significant damage to your boat and rigging.

6. Can Maneuver Shallow Water

A boat’s draft is the distance from the water’s edge to the hull’s center of gravity. It is important to know the depth of a boat’s draft since it determines the quantity of water that can be displaced for safe passage. As a result of their parallel hulls’ buoyancy, catamaran vessels can have fewer drafts without affecting their stability or their ability to maneuver. 

When it comes to hull stability and handling, monohull vessels are built with a deeper draft to protect against capsizing as well as heeling. Because of this, the catamaran was deemed suitable for use in shallow waters. 

Boating activities such as swimming and fishing aren’t the only ones that benefit from being able to dock in shallow water. A boat with a shallow draft will be more maneuverable in areas where you may have to sail through a variety of shallow areas, some more than others. 

Monohull boats with deeper drafts may be unable to access shores, intertidal zones, coral reefs, or even sandbars because of their shallower depths. Also, shallow-water swimming and snorkeling are two of the most popular pastimes for sailors plus their families. To ensure a smooth experience, you’ll need secure access to shallow waters.

There are several types of fishing that require a catamaran’s dependability and readiness, and these include trout, oystering, and clamming. These activities become much easier when you can navigate shallow waters without worrying about running aground or striking underwater objects.

7. Allows Cat to Have More Space

It certainly does. Eating and preparing food can be done side by side. One hull is used as a big cabin in the “owner versions,” which are fantastic for parties.

Most comparable-priced monohulls lack the amount of interior room seen on catamarans, especially in the primary salon, galley, plus cockpit. As a result, their cabins tend to be larger, and now even the tiniest cat in the group has a stand-up headroom in each one.

8. Offer More Privacy

The distance between the two hulls allows for greater privacy than on monohull yachts, which tend to be closer together. 

Because of the configuration, a cat offers more solitude than monohulls, and the increased separation between the main living area and the cabins makes it simpler for children to go off to sleep at a normal hour when aboard.

What Are the Differences Between Catamaran and Monohull Sailing?

Most characteristics of sailing a catamaran resemble those of sailing a monohull. In most Catamaran Sailing Boats, the abilities you acquire on a monohull, you can transfer to a cat. A few minor distinctions must be made though, including these.

Keep a steady speed during the tack to avoid “winning,” which can occur if you relax the mainsheet too much. Winning occurs when a catamaran’s larger mainsail tries to direct the boat towards the direction of the wind.

Gybing on the monohull necessitates much more caution, therefore you have to slow down your gybe considerably. Travelers on catamaran boats have an advantage since they can sustain a pace while gybing to depower the main.

You can tell when you’ve got too much sail on a monohull by the way the boat is heeling, which tells you it’s time to reef. Since catamarans don’t heel, we have to be super cautious when reefing the enormous mainsail because it’s so heavy. 

In most cases, the first reef will be thrown in between wind speeds of 18 and 20 knots (determined by the size of our yacht) and the second reef will be thrown in as the wind speeds reach up to 25 knots.

Many elements of sailing a catamaran are fairly similar to those of a monohull, so making the switch should not be too difficult.

Are Catamarans Safer Than Monohulls?

Exactly what I was looking for! People are less likely to drown when sailing on a catamaran than on a monohull, thanks to the boat’s greater stability. They are bigger, more steady vessels. In most cases, this makes cats “safer” than a monohull of the same size.

Having two engines makes catamarans “safer” in the event of an engine breakdown. Sailing is the sole alternative on a monohull boat if the motor is out of commission. In the event of an emergency, the second engine on a catamaran is always ready to assist!

Is Sailing A Catamaran Easier Than Sailing A Monohull?

It is more difficult to sail a monohull because of heeling and the constrained space it has to offer. In greater gusts, monohulls heel, making it harder to accomplish most activities. 

Sailing aboard a heeling vessel is more difficult for a variety of reasons, including heading forward to a reef, having to haul in a sail, or just moving around the boat. 

The greater stability and space provided by catamarans, on the other hand, make moving around the boat easier than on other types of boats. The fact that catamarans are typically referred to as “easier” to sail is due to this.

What is a sailing Catamaran and its advantages in navigation

What is a catamaran and how has it revolutionized the sailing experience? Catamarans, boats with two parallel hulls, have transformed sailing with their numerous advantages. Thanks to their design, they provide a more stable and safe navigation in various maritime conditions. These types of vessels stand out for being more efficient, consuming less fuel due to their aerodynamic structure. Furthermore, their spacious interior and greater height offer unparalleled comfort to passengers. With a reduced draft, catamarans have the ability to venture into shallow waters, expanding exploration possibilities. Their extensive flotation surface facilitates maneuvers, and their prolonged lifespan, combined with their commitment to the environment, has cemented their popularity in recent times. Now that you know what a catamaran is, let’s look at its advantages.

Advantages of the catamaran in sailing

Stability and safety at sea.

Catamarans guarantee extraordinarily stable and safe navigation thanks to their two parallel hulls. This unique structure allows them to remain firm in the water, ensuring a smooth journey, even when the sea becomes stormy. Both hulls work in harmony to balance the weight of the vessel, minimizing the chances of capsizing and abrupt movements. This additional stability is a hallmark for sailors, whether on extended voyages or maneuvers in ports.

Efficiency and reduced fuel consumption

The efficiency of catamarans in sailing is undeniable. Their twin-hull design minimizes water resistance, maximizing aerodynamics. This allows the vessel to harness more wind energy, translating into significantly lower fuel consumption compared to single-hull boats. This efficiency is not only beneficial for the wallet but is also an ecological advantage by reducing harmful gas emissions.

Spacious living space on board

Catamarans are synonymous with space and comfort. Their twin-hull design provides larger interiors compared to single-hulls, offering more spacious resting areas, cabins, and salons. This translates into a more pleasant and comfortable sailing experience during extended voyages. Additionally, the extra height in the design offers a feeling of openness, creating brighter and more airy environments.

Design features and flotation of a catamaran

A catamaran’s design is characterized by having two parallel hulls, which provides a series of distinctive advantages in terms of flotation and stability compared to traditional single-hulls. Next, we’ll highlight the main features of this innovative design.

Two parallel hulls design

The revolutionary design of the catamaran with two parallel hulls offers unique advantages in terms of flotation and stability. This structure allows for more balanced navigation, preventing abrupt movements and providing a more pleasant journey. Moreover, their reduced draft allows access to shallow water areas, opening a range of exploration possibilities. The extensive flotation surface facilitates maneuvers, allowing precise turns even in adverse conditions.

Reduced draft and access to shallow waters

Traveling on a catamaran is an unparalleled experience. The feeling of space, breadth, and comfort surpasses that of any conventional vessel. This comfort extends from the spacious lounges to the cabins, providing a perfect environment to relax and enjoy the journey. Additionally, the robustness of their design ensures a longer lifespan and superior resistance to ocean forces.

Flotation surface and ease of maneuvering

Catamarans are equipped with a larger flotation surface compared to single-hulls.

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.

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.

Resistance & Performance

B. ULD (Ultra Light Displacement) monohull

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.

What are the parts of a catamaran called?

• Post author By Richard

• No Comments on What are the parts of a catamaran called?

This article is a dictionary of sorts of common terms used whether slang or professional among catamaran sailors.

balsa cored (adj.) – description of a type of building technique common on catamaran used for weight saving purposes. End grain balsa is sandwiched between two layers of fiberglass to stiffen, lighten, and insulate the hull and deck of many catamarans. Usually balsa coring is discussed in terms of concerns about water logged or “wet” coring material which is a significant expensive as well as a common issue especially as catamarans get older.

beach platform (n.) – a type of platform at the back of catamaran in particular the Voyage 440. The platform runs the whole back width between the swim platforms and function as a place behind the cockpit combing to layout, fish, and dangle your feet.

beachable (adj.) – describing a class of catamaran which can safely be run aground and mooring on a sandy bottom often a beach. The hull is constructed so that the design can stay upright and support its own weight when the tide goes out.

breakaway skeg (n.) – an underwater appendage of some catamarans including some Leopard and Outremer models which protects the rudders and breaks away in the case of an impact whether in a grounding situation or underwater debris.

bridge clearance (n.) – also known as air draft. The height from the water level to the tip of the mast. Should include the height all the way to the tip most antenna. Heights provided by manufacturers often underestimate because of the antenna. A key number is 65 feet which in the United States is the limiting clearance for fixed bridges on the Intracoastal waterway. Some owners cut down their masts to get under this limit. Many manufacturers specifically design around the 65 foot limit although with catamarans this is difficult as they tend to have taller masts than other sailboats and smaller headsails for the same waterline length.

bridgedeck clearance (n.) – distance between the center section of catamaran where salon is aka the bridgedeck and the water. Common focus is if the catamaran “slaps” which means in rough seas waves come up and pound against the bottom of the hull. Higher bridgedeck clearance is preferred and considered a bluewater characteristic while low bridgedeck clearance is a common concern. A good way to measure is by extending a measuring tape from behind the cockpit to the waterline and a normal rule of thumb number is two feet.

charter version (adj.) – catamaran built for the charter trade usually Moorings or Dream Yacht Charters which has additional cabins and heads. Usually this means four cabins and four heads. This layout is ideal for charter but often private owners prefer a more luxurious master hull giving them a three cabin and two head layout.

companionway (n.) – the main opening to access the interior of the catamaran. This may be a single hatch like door for example on Mantas or large sliding doors which fold up above the cockpit like on Seawind catamarans. A key design interest for builders and owners is the connection and flow between the cockpit where the most time is spent while onboard and the galley and salon areas.

condomaran (n.) – derogative term towards space focused, performance challenged catamarans such as a Lagoon, Leopard, or Fountaine Pajot.

cored above waterline (adj.) – a description of a common build technique where to lessen water intrusion into balsa coring, that sandwich is not carried below the water line. The term is a bit deceptive as usually the coring does go farther than what most owners would think and often below the waterline although not all the way to the bottom of the hull.

crew quarters (n.) – a pretty minimal and harsh accommodations area on catamarans forward in a bow where the captain and crew are supposed to sleep and live when a catamaran is captain chartered. Often on used catamarans becomes an excellent storage area. An unlivable marvel of a cabin that is suggestive of suffering.

cross beam (n.) – beam usually metal that is forward most and the headsail attaches to. Keeps the two hulls structurally joined at the bow.

cutter (adj.) – a rare type of sailboat where there are two headsails and the mast is well aft. Easily confused with a cutter rigged sloop. See definition for sloop cutter.

daggerboards (n.) – boards used to help windward performance and common on performance catamarans like Catanas while not used on charter catamarans like Lagoons and Leopards. Helps the catamaran head further upwind and make less leeway.

davits (n.) – a critical item on a catamaran which holds and supports the dinghy behind the cockpit. Many different arrangements are common. The davits are operated using a line or multiple lines to lower the dinghy into and raise out of the water for security from getting stolen at anchor or for safety offshore. A common concern of the ocean going sailor is monitoring and making sure if rough seas that the dinghy is tight and secure.

emergency hatch (n.) – a hatch at the bottom of the boat usually under the salon or steps downward into one of the hulls which becomes an emergency escape hatch if the catamaran flips and goes turtle. Required safety feature that hopefully no sailor needs to use. Also can be used to fish from in calm water. Can be a source of leaks or come dangerously loose and cause drama offshore.

family version (n.) – a charter layout of a used catamaran that is preferable for families that usually want at least four cabins to accommodate three or more children. The best type of catamaran!

flat top sail (n.) – a high tech fancy sail with a flat top. Expensive and not as common although becoming more common. Maximizes sail area.

flybridge (n.) – helm above the cockpit common on some popular charter catamarans like the Lagoon 440 or Lagoon 50. Design allows great visibility from aloft but also roughly exposes the captain and can uncomfortably separate the owner-captain from his friends and family.

flying ahull (n.) – when one hull lifts off the water and a catamaran sails only with one hull in the water. Not a good sign for almost any catamaran even performance catamaran. Likely followed by flipping and mayday on cruising catamarans.

four heads (n.) – number of heads on many catamaran layouts preferred for charter. Each guest has a cabin and head, so that no one must share heads during their week together. Usually a negative for private ownership even for families that prefer four cabins as more heads means more problems and less space for other accommodations.

french built (adj.) – denotes the catamaran was built in France. Suggests a more performance focus like Catana or lighter production built like Lagoon. Definitely an aesthetic focus on fast striking lines.

forward cockpit (adj.) – a cockpit in front of the salon area usually accessed by a forward facing companionway door. Made famous by the Leopard 44. Some sailors question usefulness or durability in heavy seas of a large opening on the front side of a catamaran.

galley down (adj.) – kitchen area down in one of the hulls. Associated with older designs or designs seeking weight advantage of lower center of gravity such as Antares 44. Uncommon in more recent catamarans and unheard of for charter catamarans as galley down is inconvenient for four guests for sleeping an food access.

galley up (adj.) – Common for most modern catamarans. Improves flow from cockpit and helm to kitchen as well as separation of shared living areas from private cabin areas.

hard top (adj.) – solid glass top to protect guests in cockpit from sun exposure as well as give a platform above for sail handling or diving from into water. Also a sunbathing area or area for solar panels.

ICW friendly (adj.) – catamaran with rig height below 65 feet to go under fixed bridges along United States eastern seaboard.

IO drive (n.) – a rare engine and drive combination as seen on Gemini 105 MC catamarans where a single diesel engine is centerline and there is an outdrive mounted on a hinged support.

ketch (adj.) – very unusual rig configuration on a catamaran with two masts and the second mast aka mizzen mast being shorter than the main forward mast.

outboard (n.) – gas engine that mounts to a stern or inside a swim platform and includes both the motor and drive. Less expensive and easier to replace yet less durable and less safe offshore. Common on smaller catamarans under 40 feet. Can come in twin configurations or a single centerline configuration. Also a separate small horsepower outboard is usually the power for the dinghy.

owner version (adj.) – usually less common version of a production catamaran where the layout is optimized for private use not charter. These models were usually never chartered and command a premium price on the used market both because of the lower wear from private ownership and the more comfortable layout. Typically in the 40 foot range which consists of the majortiy of catamarans, this means three cabins and two heads with one hull using the missing cabin and head space for a larger head and cabin and maybe an office or lounge area.

performance catamaran (n.) – catamaran with daggerboards which is geared towards more minimal accommodations and faster, lighter performance with a more athletic crew. Rarely chartered.

production catamaran (n.) – charter type catamarans with a focus on space and cabins and low prices. Large numbers built and send to Caribbean to be bareboated for 5 years.

raked mast (n.) – a mast tilted backwards common on catamarans as compromise between performance and accommodations. Dean catamarans are a common brand known for noticeable rake.

saildrive (n.) – a type of drive common on most newer catamarans which helps maximize space and minimize drag as well as being cheaper to build. The engines are in lockers in the swim platforms instead of under the aft berths. There are maintenance issues such as increased difficulty in changing oil and underwater seals which commonly deteriorate and let raw water into and emulsify the oil.

salon (n.) – area inside the catamaran above the bridgedeck which is usually common area of inside helm, large lounge and settee, galley on galley up designs.

sloop (n.) – the most common sail arrangement which consists of a large mainsail and single headsail. The mast is well forward at the front of the salon.

sloop cutter (n.) – a less common sail arrangement of a sloop with the mast forward but two headsails.

snubber (n.) – a rope tied between the two hulls at the bow which hangs downward and has a shackle which is hooked into the anchor chain to take the load of the anchor off the windlass when deployed.

solid foredeck (n.) – a type of design where instead of tramplolines the deck is composed of solid glass. Weight is a concern and this arrangement is less common normally seen on Privileges. Allows for a more solid lounge area and additional storage on deck.

solid glass (n.) – referring to a type of catamarans usually older which does not have coring material in either the hull or deck or both. Weight is an issue and this type of catamaran is slower but the solid glass makes it also impenetrable to water intrusion a common and expensive problem on most catamarans. Examples include Catalac or PDQ catamarans.

south african built (adj.) describing a catamaran built in the second most common exporting country. These catamarans are tended to be though of as stronger and more bluewater capable than French built catamarans. Most common example is Robertson & Caine’s Leopard line of catamarans which are sold mostly to Moorings for charter.

stem (n.) – leading tips of the hulls. Often get banged up from running into things and have gelcoat and paint repairs.

tiller (n.) – a type of steering system where a long piece of wood or carbon fiber is attached directly to the rudder. Outremer is an example of a catamarans with tillers. Typically these are performance oriented catamarans and the tiller allows the helmsperson better feel of the sailing performance. The helm positioning also exposes the driver more to the elements.

trampolines (n.) – nets that are used to finish out the bow area and conserve weight on most catamarans. These are important to keep in good condition for safety reasons. Make a great lounge area and in rough seas a fun spray pad.

two heads (n.) – catamaran that either is a three or four cabin version. Some charter built versions still maintain two heads and guests in each hull must share the head.

vertical windows (n.) – windows made famous by Lagoon catamarans. These are windows around the salon that make it very light and airy and allow a higher cabin top with more headroom. The downside is more windage which affects maneuverability when in close quarters and general sailing performance.

Catamaran hulls are not like normal boats but provide increased stability. Let’s take a look at these incredible boats and how their hulls create one of the most versatile watercraft available today.

The Tamil Cholas used catamarans to ferry their troops to invade Malaysia, Indonesia, and Burma. The early paravars or fishing communities in the southern part of Tamil Nadu used two-hulled boats to fish. Polynesian seafarers were also early users of the catamaran, utilizing the watercraft to get to hard-to-reach islands. ( source )

Although the catamaran hull concept is a relatively new introduction to modern boat design , the boat has been in use since the 5th century. It was used for fishing, traveling, and transporting people and supplies. 

Parts Of A Catamaran

Here are the basic parts of the modern sailing catamaran:

• Hulls are what sets this boat apart from the rest. The catamaran has two hulls, while the monohull, as the name suggests, has only one hull. Most of the advantages of this boat are hinged on these two hulls. 
• The bridge deck connects the two catamaran hulls. 
• On top of the catamaran hulls and the bridge deck is the deck . It is where owners attach most of the equipment in a boat. 
• You can locate the berth, the galley, and other living amenities in the cabin . 
• The cockpit is where you find the navigation equipment of the boat . It is where you control the catamaran’s rudder, sails, and engine. 

Types Of Catamaran

The modern catamaran is far more different than its crude ancestor. Instead of tree cutouts, catamarans are now carbon fiber or fiberglass. Here are the different types of catamarans: 

Based On function

Pontoons are usually present on rivers and lakes and sometimes even on oceans, but they only travel near the shore.

In a catamaran pontoon-type boat, the pontoons serve as storage areas, where you will find the onboard motors. They are useful for water leisure activities such as short water trips, tubing, wakeboarding, and water skiing. 

Some pontoons may also serve as houseboats. They provide a broader, more stable platform ideal for a floating house. Plus, the space is bigger, and most of it is above water. It offers a better viewing option than a monohull. ( Source )

Small Waterplane Area Twin Hull is a catamaran-type boat that the United States Navy initially used for military purposes. They provide the water stability that is necessary when transporting heavy military equipment. 

One example of a military SWATH catamaran is the Spearhead class EPF. It is as long as a World War II escort destroyer, yet it is twice as fast at 43 knots. It can reach that speed because of its two separate hulls.

Because of their innate speed, SWATH catamarans can become patrol boats in lakes and rivers. They can easily outrun and outmaneuver standard watercraft.  

Nowadays, there are SWATH cruise ships and other non-military variations. ( Source )

Based On Design

• Sailing Catamaran

The smaller sailing catamarans do not have auxiliary engines, so the owner can propel the boat by harnessing the wind using the sails. It’s a popular choice for people with very little or no sailing experience because they are light and easy to use. 

The larger sailing catamarans are for group charters and long-distance cruising. They have become so popular lately that they now outnumber monohulls in tropical locations all over the world. They have a last, a headsail, and a mainsail. And the twin hulls have one engine each. 

• Power Catamaran

Unlike their sailing cousins, the powered catamarans do not have sails. They have massive engines which provide high speed. Their twin hulls are stronger and can carry and protect the large motors. 

The smaller “powercats” are used mainly for fishing. The bigger ones are rented out for charters and cruises. 

Catamaran Hulls Performance 

Thanks to the catamaran hulls, the boat offers many advantages over other boat types. 

• Because its dual-hull design provides a broader base, it offers more water stability than monohull boats. It makes the cat (catamaran) a popular choice for fishing expeditions and cruises.
• Riding a catamaran is ideal for people who feel seasick whenever they ride boats. The twin hulls prevent the boat from moving from side to side. The hulls allow the boat to travel smoothly, even on moderately choppy waters.
• The catamaran is the best choice when storing provisions and other household items with less heeling and bobbing. 
• The twin hulls’ stability is ideal for many activities such as cooking and partying. 
• Cats offer more moving space because of their broader base, thanks to dual hulls.
• With a catamaran, you have two great options on where to hang out. You can do it on the spacious deck or below the galley. 
• Compared to a monohull of the same size, the catamaran can accommodate more equipment and people.
• The living area in a catamaran is above the water line. This feature provides more natural light, a greater view of the outside, and better air circulation. 
• Since catamarans do not have keels, they can anchor on shallow waters, something that most monohulls will not be able to do. This ability of catamaran boats is impressive, especially if you are going around areas with many reefs and small islands.
• Catamaran hulls allow the boat to cut through the waves easier and faster. It means they require less engine power than their monohull counterparts.
• Because it has two engines and two rudders, the catamaran can easily maneuver in very tight spaces. 
• Because they do not carry heavy keels, catamarans can sail faster than monohulls. 
• The catamaran’s stability, speed, and weight make it a safer option than the monohull. It can sail in shallow waters, make a 360 degrees maneuver effortlessly, and carry more provisions. 

Disadvantages Of A Catamaran

Like any other boat type, the catamaran also has drawbacks and limitations. Here are some of them:

• The catamaran hulls prevent the boat from sailing as fast as the monohull upwind. The two hulls cause drag, and this slows the boat considerably. 
• Because of its bigger size, looking for a docking site can be more difficult and costlier than a monohull. 
• For hardcore sailing fans, the experience of sailing with a catamaran will never be able to match that of sailing with a monohull. To them, the challenge of true sailing is just not there with a catamaran.

What Are The Hulls Of The Catamaran Called?

According to the Online Etymology Dictionary, the Tamil word கட்டுமரம், which is pronounced as kattumaran, is where the word catamaran takes its name. The word means “pieces of logs tied together”. Through the years, the term has evolved into what is now a catamaran in English. 

What Are The Characteristics Of A Catamaran Hull?

• Both hulls of a catamaran complement each other to achieve very minimum water resistance. 
• Because of this, it takes less energy to propel a catamaran, whether via an engine or sails. 
• The catamaran hulls provide stability to the boat. The twin-hull significantly reduces bobbing. 
• The catamaran’s ability to keep steady on the water makes it an ideal vessel for cooking, dining, and storing provisions. 

Are Catamarans Good In Rough Water?

Catamarans are amazingly stable in rough water. The catamaran’s design and build, which provides stability, are factors why it is one of the best boats to use when the waters are choppy. 

Yes, catamarans are relatively more expensive than monohulls. Nevertheless, since single-hull boats are less expensive, their resale value is also cheap. 

If you add all the advantages that a catamaran offers – safety, comfort, and speed- it does not come out expensive.

Catamarans also come equipped with two engines, so they can travel in calm waters even when there’s no wind to power the sails. The engine also allows them to get back quickly against strong winds or tides, making them great for long trips and passages.

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

Frequently Asked Questions

Are catamarans suitable for excursions.

Catamarans are a popular choice for those looking to charter one for an excursion due to their spaciousness and stability. They provide more than enough room for comfortable traveling as well as plenty of storage space, making them an ideal option for extended cruising. Additionally, all catamarans are equipped with engines, allowing for easy navigation and maneuverability when needed. All in all, catamarans make great vessels for vacations and traveling and can be a great way to explore the waters.

What Is The Best Type Of Catamaran For Ocean Voyaging?

When it comes to ocean voyaging, the best type of catamaran is a modern performance cruiser. These vessels are designed to combine speed and comfort, with a shallow draft for navigating in and out of shallow waters. Modern performance cruising catamarans feature two hulls connected by an open deck, often with engines that give them greater maneuverability. They also generally have larger living spaces than traditional monohulls, so they can provide more comfortable accommodations during long voyages.

How Many People Can Typically Fit On A Catamaran?

A catamaran is a type of boat with two parallel hulls. Depending on the size, it can typically fit anywhere from 4-12 people plus crew. It’s important to note that the number of passengers will depend on the size and design of the boat, so it’s best to check with a manufacturer for more specific details.

A catamaran is a great choice for those looking to explore the ocean in style. They’re spacious and versatile, making them suitable for all sorts of travel plans and excursions. Plus, they can be powered by either engines and/or sails, so you can decide which works best for your needs. Charter prices can vary depending on your vacation needs. All in all, a catamaran is an excellent choice for anyone wanting to explore the open seas!

If you’re considering renting a catamaran, it’s important to do some research first. There are many different kinds to choose from depending on what your entire party has on their travel wish list – and make sure that you have a safe and fun voyage!

Whether you’re a sailing enthusiast or have recently adopted an interest in yachts, you’ve probably heard of catamarans. It can be confusing as the term seems to describe boats, ships, and even massive-cruise vessels. So, what is a catamaran?

A catamaran is a boat with two hulls and a bridge between them. Catamarans can be designed as sailboats or motorboats. A catamaran stays stable since it has a wide base, it does not have a deep keel as on a monohull . Cats are known for not heeling, increased comfort, more space, and faster speeds.

In this article, we will explore everything you need to know about this design, including its origin and its advantages.

Catamaran: A Basic Overview

The term catamaran comes from a 17th-century Tamil term kaṭṭumaram . The Tamil word stands for “tied wood,” but those vessels do not share the same working principle as catamarans. 

Even though most “tied wood” rafts in the 17th century India used two logs to keep the deck afloat, the logs acted more like pontoons than catamaran hulls. However, the commonality of two logs translated to catamarans, as these vessels generally have two hulls.

Since the term refers to the design, it is correct to refer to any vessel with two hulls connected by a bridge as a catamaran. However, technical accuracy doesn’t necessarily mean general-use correctness. While cruise ships can have catamaran design and small rafts may feature two hulls, the term is most often used for yacht-sized cruising sailboats.

Buyers who would not previously afford any vessel close to a mid-sized yacht can easily order a brand-new catamaran. Even investors interested in collecting income from catamaran renting opt for medium scale catamarans to hedge against depreciation and damage. Therefore, the term catamaran has become synonymous with medium-scale yachts with two hulls.

For the rest of this article, we’ll use the term to reflect these vessels, and if a catamaran-style cruise-ship or smaller boats are brought up, the distinction will be highlighted. It is also worth noting that even when dealing with manufacturers and industry literature, the word will refer to medium-sized yachts unless specifically differentiated.

What Are Catamarans Made Of?

One of the most interesting subjects in the overall catamaran conversation is the materials used to manufacture these vessels. That’s because different brands use different technology to compose the materials required for the hulls and other areas of a catamaran. 

Hulls of a Bali catamaran are built with sandwich infusion technology using polyester and closed-cell PVC. The brand’s catamarans are fitted with daggerboards, and material variety includes Kevlar in regions of impact and carbon fiber in the lower-weight areas.

Lagoon catamarans have a history of using solid glass below water level , but newer models have a balsa core in the submerged region . While the specifics of composting technology and materials may vary from brand to brand or even model to model within the same brand, the fact that most of these vessels are made of composite material remains consistent.

Parts of a Catamaran

One cannot ask what a catamaran is without getting curious about the various parts of such a vessel. Here is a breakdown of the various parts that go into this vell’s construction:

Unlike monohulls, a catamaran has two of these. They’re usually hollow and fitted out with beds and even a glass window to look out into the water since they’re not submerged. The hulls’ function is to push down on the water, so the water reacts by pushing the vessel up. Therefore, they play an essential role in the catamaran’s buoyancy.

Cross Beams

Because the hulls exert force on the water, there needs to be something that ensures the water’s reaction (upwards force) doesn’t break the deck. Crossbeams serve as connectors between the two hulls and hold them together such that water’s upward force is distributed evenly across the surface between the hulls. 

Depending on the size of the vessel, the number of cross beams may vary. Some of the critical characteristics of cross beams include high density and low surface area. 

A bridgedeck, as the name suggests, is a deck that serves as a bridge between the hulls. Manufacturers make a compromise between space and sailing efficiency when deciding how to design a bridgedeck for their catamarans. A bridgedeck is given significant clearance to allow for smooth sailing but not too much to leave behind, only the deck for living space. 

What you should keep in mind about a bridgedeck is that the smaller its clearance, the more water hits its bottom, causing discomfort for those sailing and dealing damage to the vessel. Also, you can’t minimize the bridgedeck without affecting the hull size, which means you have to compromise between the two.

Other Parts

While the aforementioned parts are key to a catamaran’s construction, they are by no means an exhaustive list of every vessel’s component. 

Catamarans have a topdeck, oftentimes a saloon, and separate chambers depending on the size. The standard vessel will have the interior fitting of a yacht of a similar size. Since none of these parts are specific to catamarans, a detailed breakdown of each isn’t necessary.

How Long Does a Catamaran Last?

Since catamarans aren’t impulse-buys, you must consider the longevity of the specific model you wish to buy. If you go with a boutique manufacturer without knowing about materials and construction, you may be sold a vessel that may last only seven years. 

On the other hand, brands that list their construction methods with transparency regarding materials used are more confident in their product, which has five times the longevity of a cheaply manufactured catamaran.

Suppose you wish to purchase a catamaran you want to have for 15+ years. In that case, you may avoid buying a “performance” catamaran that focuses on lightweight in favor of sailing speed and effortlessness on the waves. This conversation becomes more complicated when you consider sailing frequency and its impact on different vessels.

Generally speaking, expecting your catamaran to remain functional and smooth sailing for fifteen years is reasonable. That doesn’t mean any catamaran you purchase will fit this criterion but only suggests that you will find vessels with this longevity with relative ease.

Is It Easier to Sail a Catamaran?

It is essential to address different sizes of catamarans when this question arises. Sailing a catamaran sailboat is different from captaining a standard (yacht-sized) catamaran. Since yacht-sized catamarans can come with an autopilot, as can their monohull equivalents, the question becomes more about the sailing experience.

Your guests are more comfortable in a catamaran as the sailing experience doesn’t translate water resistance and wind to the vessel’s interior as much as it does in a monohull. Monohulls get hit by waves that pass between the two hulls of a catamaran.

As for physically sailing a catamaran-design vessel, the experience is different but not objectively easier. For instance, if you’re a seasoned monohull sailor, you’ll find what you’re used to much easier than adjusting two catamarans. 

Final Thoughts

Catamarans are self-balancing and easy to learn, making them a preferred sailing choice among novices and time-strapped sailing enthusiasts. They have recently become symbols of luxury with comfortable interiors and ample living space.
