Understanding Catamarans

Design Characteristics

Catamarans are known for their unique design, which features two parallel hulls connected by a deck. This design provides several advantages over traditional monohull boats, such as stability and speed.

With their wide beam, catamarans have a reduced risk of capsizing and can access shallow waters due to their shallow drafts 1 .

One of the notable aspects of a catamaran is its twin hulls, which offer increased living space and comfort compared to a monohull. Additionally, catamarans are often favored by recreational and competitive sailors for their excellent maneuverability 2 .

The materials used for constructing catamarans range from wood to fiberglass, and even aluminum for high-performance vessels. Aluminum catamarans are known for their strength, lightweight structure, and resistance to corrosion 3 .

Hulls and Construction

The hulls in a catamaran are crucial to its stability and performance. These hulls help distribute the weight evenly across the water surface, minimizing drag and allowing for smoother sailing.

In general, the hulls can be categorized into two types:

• Symmetrical Hulls : The hull shape is similar on both sides, which enhances balance and stability in various sailing conditions.
• Asymmetrical Hulls : One side of the hull is designed differently than the other, which can be advantageous when sailing upwind.

The construction materials used in building catamaran hulls also play a vital role in the boat's performance and durability. Common materials include:

• Fiberglass : A popular choice due to its lightweight, strength, and ease of maintenance.
• Wood : Traditional material that offers a classic look, but requires more maintenance than fiberglass or aluminum.
• Aluminum : Lightweight and strong, aluminum is an excellent choice for high-performance catamarans 4 .

Multihulls vs Monohulls

There's often a debate between the benefits of multihull boats, such as catamarans or trimarans, and monohull boats. Here are some key differences between the two:

• Stability : Due to their wide beam and reduced heeling, catamarans offer improved stability compared to monohulls. This makes them an attractive option for those who want to avoid seasickness or feel more comfortable on the water 5 .
• Speed : Multihull boats are known for their speed, which results from their ability to minimize drag and maintain a level sail.
• Living Space : Catamarans and other multihulls generally have more living space, as both the hulls and the connecting deck can be utilized for accommodation and storage.
• Maneuverability : While monohulls are known for their agility and ability to point close to the wind, catamarans can still offer exceptional maneuverability when properly sailed 6 .

Performance and Handling

Speed and Efficiency

Power catamarans have gained popularity for offering a unique combination of speed, efficiency, and stability. Their dual-hull design allows for less water resistance, which directly translates to higher speeds and better fuel efficiency compared to traditional monohull boats.

In addition, the wide beam provided by the two hulls ensures a stable ride even at higher speeds. This makes power catamarans ideal for cruising, fishing, and watersports ( Boating Beast ).

Sailing Dynamics

When it comes to sailing catamarans , the performance is affected by factors such as keel, rudders, mast, and sails.

Their wide beam and dual-hull design provide inherent stability and reduced heeling effect, making them less likely to capsize compared to monohulls.

I should also note that catamarans have a shallow draft, which gives them the ability to access shallow waters that may be off-limits to other boats ( Navigating the Waters ).

In my experience, the lighter weight of a catamaran and its aerodynamic design can contribute to remarkable sailing performance under different wind conditions.

The larger sail area relative to hull weight allows them to harness more wind power, further enhancing their speed and agility on the water.

Maneuvering and Docking

Maneuvering and docking a power catamaran involves understanding its unique handling characteristics.

The presence of two engines in separate hulls allows for more precise control in confined spaces such as marinas.

The maneuverability of these boats is typically improved by the use of dual rudders that are located close to each powered hull for efficient steering ( BoatUS ).

When docking under power, I find it helpful to carefully assess the wind and current conditions beforehand.

This is because catamarans can be more sensitive to windage due to their larger surface area above the waterline.

By understanding how these forces may affect the boat, I can make adjustments to my approach and successfully dock the catamaran without any incidents.

Safety and Comfort on Board

Safety Features

Safety is a top priority when sailing any type of vessel, including catamarans. A well-built catamaran offers several features aimed at ensuring the safety of those onboard.

First, catamarans have inherent stability due to their wide beam and twin hull design . This makes them less prone to capsizing than monohull boats. This stability allows me to confidently navigate various water conditions .

In addition to stability, catamarans are designed with positive buoyancy, making them almost unsinkable . Of course, safety equipment such as lifejackets, flares, and first aid kits should always be onboard and well-maintained.

Furthermore, you should also stay updated on weather conditions, avoid sailing in high-risk areas, and learn your boat's safe sail limits.

Living Spaces and Comfort

When it comes to living spaces, I value comfort and practicality as essential features for my time on the water. Catamarans offer a unique advantage in this regard, as their dual hulls create spacious living areas.

Most catamarans are designed with separate cabins in each hull, allowing for privacy and comfort when sleeping. Additionally, these boats typically feature shallow drafts , which means I can access shallow waters and anchor close to shore.

The main living area, or salon, is situated on the bridge deck between the hulls. It usually includes a seating area, a dining table, and a galley (kitchen). Large windows provide ample natural light and panoramic views, making the space feel open and bright. Some catamarans even have the option for an additional living area on the upper deck where you can enjoy the sun and breeze.

One aspect of catamaran living I truly appreciate is the ample storage available. Each cabin typically has built-in storage spaces for clothes, gear, and personal items. There are also designated areas for equipment such as spare sails, tools, and water toys. This makes it easy for me to keep my belongings organized and make the most of my time on the water.

Maintaining a Catamaran

Routine Maintenance

In order to keep my catamaran in the best possible shape, I make sure to perform routine maintenance tasks. These tasks are essential to extend the life of the components and ensure smooth sailing:

• Cleaning : Regularly cleaning the deck, hulls, and sails prevents buildup of dirt, algae, and other debris that could affect performance.
• Inspection : Periodically inspecting my catamaran allows me to detect any potential issues before they become significant problems. I pay close attention to the rigging, sails, and lines on my boat.
• Lubrication : Keeping all moving parts lubricated is vital to prevent friction and wear on components such as winches and pulleys.
• Antifouling : Applying antifouling paint to the hulls of my catamaran helps prevent the growth of marine organisms that can damage the boat and reduce its speed. Make sure to do this at least once a year.

Dealing with Wear and Tear

Despite my best efforts to keep my catamaran well-maintained, wear and tear is inevitable. Here's how I deal with common issues that could arise from regular use:

• Repairs : When I notice signs of wear on sails, lines, or rigging components, I make it a priority to repair or replace them promptly. Neglecting these issues can lead to more significant problems and affect the boat's performance.
• Hull maintenance : If I find dents, scratches, or stiff rudders on my catamaran's hulls, I address them immediately. Repairing any damage not only ensures smooth sailing but also prevents further issues from developing.
• Sail care : Over time, my sails can become stretched, torn, or damaged due to exposure to sun, wind, and saltwater. Regularly inspecting them for signs of wear and making any necessary repairs or replacements helps maintain optimal performance.
• Rust and corrosion prevention : Since my catamaran is made of various metal components, I need to protect them from rust and corrosion. I routinely check for signs of corrosion and apply anti-corrosive treatments when needed.

Catamaran Brands and Models

High-Performance Models

In recent years, there has been a growing interest in high-performance catamarans. I have seen a variety of brands and models that have impressed me with their performance capabilities. One notable brand is Fountaine Pajot , which has a long history of producing a range of sailing catamarans and power catamarans. Some of their popular models include the Tanna 47 and the Bali 4.4 .

Another high-performance catamaran I've come across is the Leopard 40 . Known for their speed and exceptional handling in various conditions, the Leopard brand started with sailing catamarans and has since expanded to include power catamarans. Their models range from 40 to 53 feet long, offering both power and luxury for those looking for a thrilling experience on the water.

Cruising Catamarans

When it comes to cruising catamarans, the Lagoon brand is synonymous with luxury and comfort. With a range of sailing catamarans from 40 to 70 feet long, Lagoon offers spacious catamarans for extended bluewater cruising. Their 60- and 70-foot power catamarans are equally impressive, providing ample living space and smooth sailing experiences.

I've also found the Aquila 42 PC to be a remarkable cruising catamaran. With a focus on design and innovation, Aquila has produced catamarans perfect for exploring the open sea with friends and family. Their spacious, stable designs allow for a more enjoyable and serene journey, ensuring you arrive at your destination comfortably.

The Catamaran Lifestyle

Anchoring and Cruising

I find catamarans to be a fantastic choice for cruising and anchoring , which is a critical part of living the catamaran lifestyle . Catamarans have several advantages when it comes to anchoring and cruising, such as:

• Stability : Due to their wide beam and twin hulls, catamarans remain stable during anchoring, which reduces the risk of seasickness.
• Shallow draft : Thanks to their shallow draft , catamarans can anchor close to shore, enabling better access to protected coves and more beautiful beaches.
• Speed : Despite their large size for cruising vessels , catamarans are generally faster than monohulls. This is a result of their slim hulls and reduced water resistance.

When it comes to anchoring, catamarans can make use of their shallow draft to anchor in locations that other boats cannot. This allows for a greater range of cruising spots, which makes the overall experience much more enjoyable and unique.

Living on a Catamaran Full-time

For many catamaran enthusiasts, the dream of living full-time on a catamaran is entirely possible. While not without challenges, there are several factors that make living aboard a catamaran an enjoyable experience:

• Spacious living areas : Catamarans generally have more living area compared to monohulls, providing ample space for the whole crew.
• Privacy : The separate hulls allow for private cabins, ensuring that everyone on board has their space.
• Stability : As mentioned earlier, catamarans are stable vessels, making living on them more comfortable than monohulls.

Choosing Your Catamaran

Comparing Models and Features

When I start to look for the perfect catamaran, the first thing I focus on is comparing various models and features .

I determine the key factors that are essential for my needs, such as size, passenger comfort, and performance. By doing so, I can identify which catamaran models are most suitable for me.

For example, if I plan to sail with a large group, I would look for a catamaran that offers ample space both inside and out.

To help me with my comparisons, I usually create a table or list of the different models and their features:

This visual aid makes it easier for me to sort the options and prioritize my considerations, such as price, yacht type, and brand.

New vs. Second-Hand

Another critical aspect of choosing a catamaran is deciding between a new or second-hand boat.

Both options have their pros and cons, and ultimately it depends on my preferences and budget.

If I can afford a new catamaran, I get the advantage of the latest design , features, and technology. Plus, I typically receive better warranty coverage and support from the manufacturer.

However, new catamarans are more expensive and can have long wait times due to high demand.

On the other hand, purchasing a second-hand catamaran can save me a significant amount of money, and I might find a high-quality boat with low mileage or well-maintained by the previous owner.

However, this option carries more risks, as I need to be knowledgeable about potential maintenance issues and conduct a thorough inspection before purchase.

Learning Resources

2023 Boat Buyers Guide: Catamarans

• By Karl Anderson
• December 27, 2022

The popularity of the multihull (aka catamaran or cat) fishing boats has never been greater, as more and more boatbuilders enter this growing segment of the market. The inherent stability of the catamaran design rolls less with the seas, making fishing offshore less tiresome and more comfortable. Available from 20 to 48 feet, catamarans typically offer a large fishing platform with generous storage and fishing amenities. They are available in a wide variety of deck layouts, including center-consoles, dual-consoles, and even pilothouse and express variants.

Big Picture

The large deck area of a catamaran enables many large underdeck storage lockers and insulated fish boxes in the sponsons. This gives anglers ample room for gear and the day’s catch. The catamaran’s stability, fishability, and smooth ride in rough seas make it attractive to anglers as well as day-cruisers. A center-console version adds 360 degrees of angler access to the rail. With the dual-console design, generous seating behind a beam-to-beam windshield makes for a great family fishing-friendly setup.

Live bait is one of the most popular types of fishing in virtually every coastal zone. To do it successfully requires optimal water capacity and proper flow. The minimum size of the outflow water plumbing should be twice the size of the inflow. The plumbing should have a drain at the bottom to shed scales at the end of the day, as well as a drain at the top of the well to adjust capacity and allow overflow. Above-deck transom-mounted wells should fully flood to the lids when running to keep baits from getting beat up. 

Tip: A sump box with multiple pumps in case a pump fails is the best setup for first-rate livewells. Conveniently located inflow and outflow valves make it easy to optimize the flow without tiring your bait from swimming too much in the well. 

Rod Storage

Having enough rod holders is essential to be successful for opportunity fishing. Look for vertical rod storage along the console and across the back of the T-top. Many models also have rod holders along the outboard transom wall. Having plenty of gunwale rod holders for drift- and kite-fishing is helpful. 

Tip: Placing adjustable swivel rod holders by Gemlux makes deep-dropping, lure-fishing and drifting even easier because they allow your rods to face the direction the baits are fishing, yet they can be swiveled back to keep rods from sticking out of the boat while running and docking. 

Manufacturers often offer multiple choices for horsepower, but whatever the choice, the engines must come in pairs. For example, you might order twin outboards (one for each sponson) or four outboards (two for each sponson), but single- or triple-outboard configurations are not common on a cat. Optimal selection should be made based on user load, weight of the boat, ride comfort , performance desires, and best case for resale. It’s a rare day when you can run wide open, but having more horsepower gives better torque at slower speeds and thus better control. Running larger engines slower gives better fuel efficiency too.

Tip: When possible, choose the highest horsepower offered because it typically leads to a better resale value with a shorter sales cycle. 

Power steering from engine manufacturer Optimus or SeaStar is essential with the higher horsepower required for larger boats, and it makes installing and operating the upper station in a tower far more practical and comfortable.

With the power demands of electronics, livewell pumps, stereo amps and more, it is wise to have at least two house batteries, and for larger boats, a third or fourth with a multibank charger for dockside. Each engine should have its own dedicated battery as well. 

Electronics

Typically choosing the largest screen or multiple screens that will fit on the console is best-case scenario for ease of use, ergonomics, and visibility. VHF radios, stereo controller, and equipment switches for lighting, pumps, and accessories should all be integrated with greatest visibility and ease of operator reach. 

A Tale of Two Hulls 

A catamaran rides on pair of hulls, or sponsons, each thinner and sharper than  that of a similarly sized monohull boat. The narrow sponsons of the cat tend to slice easily through water to deliver a smooth ride, even in rough seas. At the same time, with the sponsons positioned out to the sides of the boat, cats tend to roll less, thus providing great stability to enhance crew comfort, security and safety. However, cats tend to corner more flatly than a monohull, and some hulls (but not all) tend to lean outward versus inward during a turn.

Experts Say

Newer designs such as Invincible’s Morelli and Melvin-designed semi-asymmetrical sponsons eliminate some of the negatives of the cat design, such as “sneezing,” where water sprays out the front of the boat when hitting a wave. They’ve also controlled the uncomfortable “outboard lean” ­sensation common in older designs when in a turn. Once transitioned to a ­catamaran, many become true believers and preach the benefits of the design.

Editor Says: Saltwater fishing cats not only offer superb stability and smooth ride, but some also display exceptional speed and range. I recall one trip out of Key West, Florida, aboard an Invincible 40 Cat with four 350 hp outboards to the Dry Tortugas. It was a 60-mile run, and we made it there in 70 minutes. We caught more fish than our arms could bear, and then dashed back to Key West, arriving in time for cocktail hour on the same day. -Jim Hendricks, Staff Editor, Boating and Fishing Group

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

Last Updated by

Daniel Wade

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.

Table of contents

‍ How to Spot a Catamaran

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

How do Catamarans Work?

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

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

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

Catamaran Vs Monohull

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

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

Benefits of Catamarans

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

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

Drawbacks of Catamarans

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

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

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

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

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

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

Catamaran Vs Trimaran

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

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

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

Types of Catamarans

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

Sailing Catamaran

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

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

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

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

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

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

Power Catamarans

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

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

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

Military and Commercial Catamarans

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

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

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

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

Catamaran Houseboats

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

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

Why Aren’t Catamarans More Common?

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

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

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

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

Cruising the Seas in Splendor: Unveiling the Majesty of Catamaran Boats

Catamaran boats have been gaining popularity in recent years due to their unique design and numerous benefits. These boats are built with two hulls instead of one, which provides a more stable and comfortable ride.

They are also faster and more fuel-efficient than traditional monohull boats, making them a popular choice for both recreational and commercial use.

One of the biggest advantages of catamaran boats is their stability. The two hulls provide a wider base, which makes them less likely to tip over in rough waters. This stability also makes them a great choice for those who are prone to seasickness or who want to enjoy a more comfortable ride.

Additionally, the shallow draft of catamarans allows them to access shallow waters that are off-limits to larger boats, making them ideal for exploring secluded coves and beaches.

Overall, catamaran boats are a great choice for anyone looking for a stable, comfortable, and efficient vessel for both recreational and commercial use.

With their unique design and numerous benefits, it’s no wonder that they have become increasingly popular in recent years. Whether you’re looking to sail the open seas or explore secluded coves, a catamaran boat may be the perfect choice for your next adventure on the water. Now let’s take a more in-depth look at this type of leisure craft.

What is a catamaran boat?

A catamaran boat is a type of watercraft that features two parallel hulls connected by a deck or platform. This design provides stability, speed, and efficiency on the water, making it a popular choice for various purposes such as leisure cruising, racing, fishing, or even luxury yachting.

Catamarans have been around for centuries but have gained significant popularity in recent years due to their unique advantages over traditional monohull boats. One key characteristic of catamaran boats is their wide beam or width compared to monohulls.

This attribute allows for excellent stability and better weight distribution, providing passengers with a smoother ride even in rough waters. The wider deck layout of catamarans also offers more space for recreational activities and amenities such as sunbathing areas, dining spaces, and storage compartments.

Whether it’s a power catamaran designed for speed and efficiency or a pontoon-like sailing catamaran built for comfort and relaxation, these boats provide ample room for both functionality and comfort. Catamarans are available in various types to cater to different boating preferences.

Power Catamarans are known for their ability to navigate through the water swiftly while maintaining stability. Their twin-hull design reduces drag and allows them to maintain higher speeds with less fuel consumption compared to traditional powerboats.

On the other hand, Sailing Catamarans focus on harnessing wind power efficiently with their multiple sails and rigging systems . When considering purchasing or renting a catamaran boat, it’s important to know that different brands offer different features tailored to specific needs.

Luxury catamarans often come equipped with high-end amenities like spacious cabins, swimming pools, gourmet kitchens, and luxurious interiors designed for an extravagant experience on the water. Some popular luxury catamaran brands include Lagoon Catamarans and Leopard Catamarans.

For those looking at smaller options suitable for day trips or weekend getaways, there are various small catamaran brands to explore. These compact vessels often prioritize efficiency and ease of handling while providing enough space for a small group of people.

They are perfect for exploring coastal areas, shallow waters, or inland waterways. Catamaran boats offer a unique and versatile boating experience with their twin-hull design, wide deck layouts, and various types tailored to specific needs.

They provide stability, speed, and ample space for recreational activities or luxurious amenities. Whether it’s the power and efficiency of a racing catamaran or the comfort and relaxation of a luxury catamaran, these vessels have become increasingly popular in the boating world as they redefine the way we navigate through water.

Design and Structure of Catamaran Boats

Catamaran boats are fascinating watercraft known for their unique design and structure. The foundation of their design lies in the arrangement of two hulls, parallel to each other, connected by a platform or bridge-like structure. This configuration sets them apart from traditional monohull boats and brings forth a range of advantages that I will explore later in this article.

The design and structure of catamaran boats allow for superior stability on the water. With two hulls instead of one, catamarans have a wider beam, providing excellent balance and reducing the chances of capsizing.

This stability makes them an ideal choice for those who prefer smooth sailing experiences without sacrificing safety. Furthermore, the wide beam also contributes to maximizing living space on board.

Catamarans often boast spacious interiors that can accommodate more passengers comfortably, making them popular choices for luxury cruises or large groups seeking adventure on the open seas. Small catamaran brands often focus on enhancing space utilization while maintaining efficiency.

The deck layout of catamaran boats is carefully designed to ensure efficient movement and ease of handling. Whether it’s Power Catamarans used for leisurely activities or Racing Catamarans built for exhilarating competitions, their respective deck layouts are tailored to meet specific needs.

Another integral component is the rigging system utilized by catamarans equipped with sails. These systems consist of masts, booms, and ropes designed to optimize sail control.

The aerodynamic shape of catamaran sails contributes to increased speed and maneuverability when compared to other types of sailboats . Luxury Catamarans often incorporate innovative features such as spacious sun decks, swimming platforms, jacuzzis, or even onboard movie theaters.

These enhancements provide an indulgent experience for those seeking high-end yachting adventures. It is worth mentioning Pontoon Boats as they share some characteristics with catamaran designs due to their multihull configuration.

However, it is important to note that pontoon boats are generally used for calmer inland waters, while catamarans excel in open ocean conditions. The design and structure of catamaran boats are a testament to their engineering ingenuity.

The parallel hulls, coupled with the carefully designed deck layouts and rigging systems, contribute to their stability, speed, and spaciousness. As a result, catamaran boats have become popular choices for those seeking comfortable and exhilarating sailing experiences on both leisurely excursions and competitive races.

Types of Catamaran Boats

When it comes to catamaran boats, there exists a wide range of types catering to diverse needs and preferences.

These vessels are designed and built with specific purposes in mind, allowing enthusiasts to choose one that suits their desired activities on the water. From sailing catamarans to luxury powerhouses, there is a catamaran for every taste.

Sailing Catamarans

Sailing Catamarans are perhaps the most iconic among all types. These boats utilize the power of the wind with specialized catamaran sails to propel themselves through the water.

Sailing catamarans are known for their stability, speed, and comfortable sailing experience. They often feature spacious deck layouts with ample seating areas and come equipped with advanced rigging systems for efficient control.

Power Catamarans

On the other end of the spectrum are Power Catamarans. These boats prioritize speed and maneuverability over wind propulsion.

Powered by engines instead of sails, these vessels offer a thrilling experience on the water. Power catamarans often have sleek designs and can reach impressive speeds while maintaining stability due to their dual-hull configuration.

Racing catamarans

For those seeking high-performance vessels built for racing, Racing Catamarans fit the bill perfectly. These lightweight and agile boats are designed specifically for competitive sailing events where speed is paramount.

Racing catamarans feature aerodynamic hulls, advanced rigging systems, and optimized sail plans that allow them to glide effortlessly through the water at incredible speeds.

Luxury Catamarans

Luxury Catamarans cater to those who seek premium comfort and opulence on their seafaring adventures.

These high-end vessels combine exquisite interior design with top-of-the-line amenities such as spacious cabins, luxurious lounges, gourmet kitchens, and even lavish entertainment systems. Luxury catamaran brands focus on providing an unparalleled level of luxury while still ensuring superior performance on the open water.

Small Catamaran Brands offer compact options that are suitable for various recreational activities such as fishing or cruising on smaller bodies of water. These catamarans often feature simpler deck layouts with ample seating for a few passengers.

Smaller catamaran brands typically focus on affordability and versatility, making these vessels accessible to a wider range of boating enthusiasts. The types of catamaran boats available cater to a diverse range of preferences and activities.

Whether one seeks the thrill of sailing, the power of engines, the excitement of racing, or the luxury of opulent interiors, there is a perfect catamaran waiting to be discovered. From sailing catamarans with advanced rigging systems to luxury powerhouses and racing machines, these vessels offer an unforgettable experience on the water for enthusiasts of all kinds.

Advantages of Catamaran Boats

Catamaran boats offer a multitude of advantages that make them a desirable choice for boating enthusiasts. From stability to comfort, these vessels have proven themselves to be a worthwhile investment.

One prominent advantage of catamaran boats is their exceptional stability on the water. The dual-hulled design provides a wide beam, ensuring superior balance and reducing the risk of capsizing, even in rough seas .

This stability factor makes catamarans an excellent choice for those prone to motion sickness or seeking a smooth sailing experience. Another advantage lies in the generous living space and comfort offered by catamaran boats.

With two hulls instead of one, there is ample room for cabins, lounges, and other amenities. Luxury catamarans are particularly renowned for their spaciousness and lavish interiors, providing an unparalleled level of comfort during extended trips or liveaboard experiences.

Catamarans also shine when it comes to fuel efficiency. Compared to other types of vessels like powerboats or pontoon boats , catamarans generally require less horsepower to achieve similar speeds due to their lightweight construction and reduced drag in the water.

This efficiency translates into lower fuel consumption, making them an environmentally friendly option as well as more cost-effective over time. Furthermore, catamaran boats boast impressive sailing performance due to their unique rigging system and deck layout.

The wide beam allows for greater sail area compared to monohull sailboats while maintaining excellent stability. Sailing catamarans can harness the wind more efficiently with larger sails that propel them forward swiftly and gracefully through the water.

Racing enthusiasts are particularly drawn to the advantages offered by racing catamarans. These specialized vessels are designed with cutting-edge technology and aerodynamics that result in exceptional speed on the water.

The multi-hull structure allows racing catamarans to skim across waves with minimal drag while maintaining superb maneuverability. Additionally, it is worth mentioning that catamarans are available in a wide range of sizes and configurations, catering to diverse preferences and needs.

From small catamaran brands that focus on affordability and simplicity, to high-end luxury catamarans designed for opulent cruising, there is a vessel suited for every boating enthusiast. The advantages of catamaran boats are truly remarkable.

Their stability, spaciousness, fuel efficiency, sailing performance, and diverse range of options make them an attractive choice for both leisurely cruising and competitive sailing. Whether you are a seasoned sailor or a recreational boater looking for comfort on the water, exploring the offerings from various catamaran brands is sure to reveal the perfect vessel to suit your desires.

Disadvantages of Catamaran Boats

While catamaran boats offer numerous advantages, it is important to acknowledge that they also come with a fair share of disadvantages. These drawbacks, although not deal-breakers, should be considered when making a decision about purchasing or sailing a catamaran.

Firstly, one notable disadvantage of catamaran boats is their wide beam . Due to their dual-hull design, catamarans tend to have a larger width compared to monohull vessels.

While this provides stability and ample space for accommodation and deck layout, it can present challenges in terms of docking and maneuvering in tight spaces. The wider beam requires special attention when navigating marinas or crowded anchorages as it may limit access to certain berths or docking areas.

Secondly, the increased windage caused by the wider beam makes catamarans more susceptible to being affected by strong winds . The larger surface area exposed to wind can result in greater resistance and difficulties in steering during adverse weather conditions.

While modern catamaran designs have addressed this issue through improved hull profiles and efficient rigging systems, it remains an inherent characteristic that requires careful consideration. Another disadvantage lies in the potential limitations of shallow draft capabilities.

Although some catamarans are designed with retractable keels or daggerboards that enhance their ability to navigate shallow waters more effectively than monohulls, there are still limitations depending on the specific model and size of the boat. This can restrict access to certain anchorages or require cautious navigation in areas with potentially shallow shoals.

Additionally, compared to monohulls, catamarans may be perceived as less suitable for racing purposes due to their increased weight and form drag caused by their wider beam. While high-performance racing catamarans exist within specialized classes such as Formula 18 or A-Class Catamarans, they are not as widely available as monohull racing sailboats.

Therefore, those seeking competitive racing experiences may need to explore other options outside the realm of catamaran sailing. Cost can be a significant disadvantage for those considering purchasing a catamaran.

Catamarans, especially when compared to smaller monohull or pontoon boat options, tend to be more expensive due to their larger size and increased construction materials. Luxury catamarans with high-end fittings and finishes can command even higher prices.

Additionally, maintenance costs for catamarans may be higher than for monohulls due to the dual-hull structure and the complexity of certain systems such as rigging and sails. While catamaran boats offer numerous advantages such as stability, spaciousness, and efficient sailing capabilities, they also come with several disadvantages that should not be overlooked.

The wider beam affecting maneuverability and wind resistance, potential limitations in shallow draft capabilities, reduced availability of racing options compared to monohulls, and the higher overall cost are aspects one must consider when evaluating whether a catamaran is the right vessel for their needs. Understanding these drawbacks will enable potential owners or sailors to make informed decisions regarding this unique style of boat.

The Cost of Catamaran Boats

The Cost of Catamaran Boats When considering the purchase of a catamaran boat, it is crucial to delve into the cost aspect. Catamaran boats come in various sizes, designs, and configurations, leading to a wide range of prices.

The price of a catamaran boat can be influenced by factors such as brand reputation, size, construction materials, added features, and market demand. Whether you are looking for small catamarans brands or luxury catamarans capable of crossing oceans in style, there is a price range to accommodate every buyer’s preferences and budget.

Small catamaran brands usually offer more affordable options for those starting their journey into the world of multi-hull sailing. These compact vessels often range from 20 to 35 feet in length and are designed for day trips or weekend cruising.

With simpler deck layouts and fewer amenities compared to larger models, these smaller catamarans typically have lower price tags starting from around $50,000 for used boats and reaching up to $300,000 for newer models. On the other end of the spectrum lie luxury catamarans tailored for discerning buyers seeking opulent accommodations and top-of-the-line features.

These floating wonders can stretch up to 80 feet or more in length and boast sophisticated interiors that rival five-star hotels. With high-end amenities such as multiple en-suite cabins with private bathrooms, spacious lounges outfitted with modern entertainment systems, gourmet kitchens with high-quality appliances, and expansive deck spaces perfect for hosting extravagant parties or sunbathing sessions; it’s no wonder these luxurious vessels command hefty price tags ranging from several million dollars upwards.

For those interested in racing catamarans built specifically for performance-oriented sailing competitions; prices vary depending on the level of customization desired. Racing catamarans prioritize lightweight materials like carbon fiber constructions which contribute to enhanced speed capabilities on water surfaces.

Buyers should expect prices upwards of several hundred thousand dollars for professionally designed racing catamarans that incorporate cutting-edge rigging systems, advanced catamaran sails, and specialized hull shapes to maximize speed and maneuverability. Power catamarans, while sharing the multihull design with their sailing counterparts, offer an entirely different boating experience.

These motorized vessels combine stability and fuel efficiency to provide an enjoyable cruising experience for those who prefer to explore the open waterways without relying on wind power. The cost of power catamarans can vary widely depending on factors such as size, engine specifications, interior amenities, and brand reputation.

Entry-level power catamarans start around $200,000 and can reach multi-million-dollar price tags for larger models equipped with luxurious features. Ultimately, when it comes to the cost of catamaran boats; buyers need to consider their specific requirements and desired features.

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

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

What Is A Catamaran?

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

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

Advantages Of Catamarans

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

Types Of Catamarans

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

Sailing Vs. Motor-Powered Catamarans

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

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

Benefits Of Chartering A Catamaran

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

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

Catamaran Boats: Types, Uses & Activities

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

Sailing Catamarans

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

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

Power Catamarans

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

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

Advantages of Catamaran Boats

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

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

Drawbacks of Catamaran Boats

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

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

Catamaran Boats FAQs

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

Are catamarans more expensive than monohulls?

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

What is the typical draft of a catamaran?

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

Can catamarans be raced?

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

Catamaran Hulls- Everything You Need To Know

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.

A Catamaran, also known as a cat, is an excellent watercraft for both sailing and cruising. It is basically a boat with two hulls instead of one. A monohull, or what you think of as a regular boat, has only one. A hull is the main body of a boat, including the sides and the bottom.

Catamarans come in a variety of types and models. So, if you’re in the market for one, this article will help you understand everything you need to know.

What Is a Catamaran

For those of you who are new to boating, let’s go over the basics. As mentioned above, a catamaran is a boat that comes with double hulls. The two hulls are built to provide as much balance to the boat as possible. The hull is positioned such that it lies beneath the water’s surface. The placement of the hull makes it safer and simpler for the boat to sail when high tides and fast currents strike with full force.

What Is A Catamaran Used For?

Over the years, the catamarans have evolved from being just a sailboat or fishing boats. The design and the construction have been modernized as well the usage and activities.

The catamaran was first designed for fishing, hence the double hulls, which provide balance. Today, the catamaran types and usage has grown into various branches. Now catamarans are one of the best boats for cruising and sailing.

What Is The Difference Between A Catamaran And A Normal Boat?

If you’re only recently getting into boating, it might be a little tricky to tell the difference between two boats.

However, there are a few ways you can tell the difference between a monohull and a catamaran.

Hands down, the most visible difference between a catamaran and a monohull is the shape. A regular sailing boat has one hull which is the bottom. Catamaran boats, however, are a multi-hull. So instead of one, the catamaran boat has more than one point of contact with the sea. A platform across the top joins the two hulls, bringing them together as one vessel. Having two hulls, less of the catamaran is below the water, allowing you to sail it in shallower seas.

Sailing Experience

The extra hull on catamarans slow them down, so this is not the fastest among your choice of watercraft. Though both luxurious, a catamaran is not as fast as a yacht. Many seasoned boaters will tell you that sailing a yacht can be quite exciting due to its speed and the ease of changing directions.

Compared to monohulls, the heavy weight of catamarans makes them more stable on the water. It moves a little with the water, but it does not heel over as easy as a yacht would. This makes the catamaran an excellent option if you are a beginner or boating with children. It allows children to walk around on deck comfortably.

Freedom Of Movement

You might think the catamaran would be difficult to pilot around just it is heavy, but actually it’s not. A catamaran is easier to pilot than a monohull. It has two separate engines, which allows you to adjust your position using one or both engines quickly.

A catamaran is able to turn 360 degrees within its own length. Furthermore, due to the fact that a catamaran has two hulls, wind speed and direction have less of an impact on it. The wind does affect the catamaran in the same way it does a monohull watercraft, but it only affects one hull, so the second one helps keep it steady.

Board And Carbin Space

Catamarans can be much larger than monohull watercraft since they have two hulls and a platform in between.

The catamaran is relatively wide, so it has a lot more space to maneuver about the water. As you may know, some monohulls, for example, are difficult to maneuver.

On a catamaran, the extra space is usually used to provide more seating areas like relaxing and socializing.

Most rooms are usually en-suite, but everyone on board would likely share the toilets on most monohull sailing watercraft.

Also, the galley area is large enough that it has a counter space and other domestic essentials such as a

• cooking range,
• dishwasher,
• fridge and freezer, lounging areas, and other stuff that makes your sailing experience a luxurious one.

  Catamarans are more expensive than most monohulls due to their features and size.

They also have higher marina fees since they occupy more space in the marina.

For the nights you spend at a marina, you’ll burn twice as much fuel in a catamaran as you would in a monohull. Overall, because of the two engines, the fuel cost will be doubled.

Types Of Catamarans

There are two major types of catamarans:

• Cruise Catamaran

Sailing Catamaran

Cruise catamarans.

If you’ve ever been on a catamaran cruise, you know how wonderful the experience can be. The cruise catamarans boats are also known as luxury or ferry catamaran. They provide the highest amount of luxury to their passengers, and the addition of engines makes the trip more appealing to those concerned about safety.

The cruising catamaran is considered one of the fastest boats. It is able to travel to and fro at high speed.

The Stena Voyage, which operates on the Irish Sea, and the Victoria Clipper IV, operating between Seattle and Victoria in the USA, are prominent examples of cruise catamarans.

  If you have an interest in experiencing the life of a sailor, then the sailing catamaran is for you. This type of catamaran is used for recreational purposes by people interested in sailing. It does not have residing areas, meaning it is not designed for human comfort. In a day, the average journey length a sailing catamaran can achieve is up to 300 nautical miles.

Top Five Catamaran Models In 2021

Here are some of the newly released catamaran models in 2021

INDEPENDENCE CATAMARAN IC36

The Independent Catamaran’s IC36 is known to be one of the fastest Catamaran models. If what you’re looking for is a high speed Catamaran for cruising, then you should definitely consider IC36.

The IC36 has ultra-narrow hulls, high-displacement bows, and a spinning carbon rig with composite supports as an option.

Ultra-narrow hulls allow the boat to maintain stability even at high speeds on the sea surface.

The displacement hulls allow the boat to travel more smoothly through the water. Boats with displacement hulls move through the water by pushing the water aside. Because of how the hulls are designed, they cut through the water with very little propulsion.

You can clean up the leading edge of the airfoil by rotating the mast into the wind. This also helps eliminate turbulence.

The spinning carbon rig raises the lift force and advances the lift angle forward. By doing this, it allows you to travel faster and direct more accurately.

Special Features

In every category of boats, there is a series of unique features which makes them stand out. Most of these features can only be found in new catamaran models.

Let’s take a look at some special features of the IC36.

Space – The IC36 catamaran is a very spacious model. It comes with enough space to hold up to eight people, and additional domestic essentials such as a fridge, two-burner stove, and shower.

Design and Safety – Many boaters claim that this catamaran model has a reputation of being unsinkable. As you know, one of the major reasons for capsizing is an overweight boat. The IC36 is constructed in epoxy-glass composite with local Kevlar

reinforcement and foam core. To further ensure safety, there are three buoyancy chambers in each hull. These help to maintain the weight below 3 tons, thus lowering the chances of capsizing.

Speed – The independent catamaran’s IC36’s speed reaches up to 20 knots and more. This is because of the light weight and the high-performance rig of this model.

A catamaran is a multi-hulled watercraft that is for its luxurious and elegant appearance. It provides sailors and cruisers with luxury, comfort, and optimal safety. The most obvious difference between a catamaran and a regular boat is that a cat has two hulls, whereas a typical boat has only one. The hulls are built to be of equal size and provide the boat with stability. Although it is highly pricey, the catamaran is an excellent choice for beginners. The catamaran is available in a variety of styles, brands, models, and prices. This article goes through the various types, brands, and models of catamaran in great detail. Which is everything you need to know about the Catamaran, especially as a beginner.

Answer:  Yes, as a matter of fact the new models have been built and designed to travel up to 200miles in a day. The hulls of the catamaran are more sturdy and comfortable, providing balance and stability.

Answer:  Because of its stability, the catamaran is much easier to move around. So to answer the question, yes it is easy to sail.

Answer: Normally, the life span of a boat depends on the type, how often it’s used, the construction materials and how well it’s maintained. However, an average catamaran can last up 15 to 25 years.

Answer:  No the catamaran do not flip easily, because they are highly stable.

Answer:  Sailing across the Atlantic takes roughly 3-4 weeks, but if you’re lucky, take shortcuts, and have a speedy sailboat, you can reduce it down to two weeks.

Answer: Yes, catamarans are ideal for beginners. They are by far the most reliable options, despite the fact that they may be more expensive. Because a catamaran has two hulls, it is often wider. As a result, your chances of capsizing are quite slim.

Answer: Underwater, a Catamaran is a Stable and Safe Platform. Catamarans, unlike monohulls, do not have ballast in the keels, hence they rely on beam and buoyancy for stability.

Answer: Catamarans can travel at speeds of 15 to 30 mph, with the fastest reaching speeds of well over 60 knots. Sailing catamarans can travel twice as fast as monohulls. Also it can cut through the water more efficiently.

Answer: A catamaran’s maintenance will cost between 5 and 15 percent of the boat’s value. As a result, a $300,000 cat will cost between $15,000 and $30,000 every year. This figure excludes major renovations and covers the expense of annual haul-outs, insurance coverage, and yearly boat service and repairs.

Answer: On average, annual catamaran insurance will cost roughly 1.5 percent of the boat’s value. The cost of insuring a catamaran is determined by the boat’s hull value, location, and intended use.

Answer: Normally, routine maintenance will prolong the lifespan of your boat. However, with a catamaran, how often you need maintenance depends on how often you use it. The general norm is to service after every 100 hours.

Answer:  The trampolines on the boat is used for a lot of thing. First, it allows water to move swiftly through it which the bow to rise, preventing the vessel from flipping.

Catamarans: Advantages and the Downsides of a double-hulled

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.

The Best Catamarans for Sailing Around the World 

A catamaran is a double-hulled boat with a deck or cabin area in between (bluewater cat definition in this article ). The double hull design means that the boat rocks less, sits higher on the water, uses less fuel to sail, and can be sailed in shallower waters than a single-hulled boat without worrying about grounding. 

Catamarans come in a variety of sizes and can be sail-powered or motor-powered and range from single-person sailing boats to family-sized yachts. Every catamaran design is different, and the twin-hull shape offers many ways to customize the layout of a ship. 

Each boat on this list is a larger catamaran (+40ft, more on size here ), so if you’re going to sail around the world, you want lots of space for provisions and rest.

Of course, there are tons of technical specs for each of these boats, but I’m going to focus on the overall features of each of these catamarans, what makes them stand out, and why they would each be an excellent choice for a transatlantic journey. 

Antares 44i 

The Antares 44i is an excellent option for sailing around the world and was explicitly designed for long-distance cruising. It performs well in any weather conditions, can be sailed easily by two people, and you’ll be able to sail long distances and live in comfort. 

Although it can be easily sailed by a crew of two I believe that a true bluewater cat should be set up for single-handed sailing, more on that in another article .

This catamaran features a stateroom on each hull and a forward cabin with plenty of storage space. The living and entertainment features include a flatscreen tv and a high-end deck speaker system. 

With this model, Antares dedicates itself to high-quality boats with optimal rigging and engine configurations. 

Atlantic 42

Atlantic is no longer building this catamaran, but there are usually a few pre-owned boats on the market. You can also get it made custom if you love the design, but be prepared to spend more money on a custom boat (custom boat also gets custom problems ;)). 

The Atlantic 42 is slightly smaller than some of the other catamarans on this list but is a seaworthy vessel. 42 ft is what most sailors I interview ( in this article ) said was the smallest cat to safely cross big oceans. It is also a decent size to counter the risk of capsizing (more on that here ).

It has a forward cockpit and pilothouse, which gives the owner a better use of space and makes the boat easier to navigate. With single-handed capability, one person can sail it easily and let the rest of the crew relax. 

One of the best-praised aspects of the Atlantic 42 is its galley, more extensive than most 42-footers (12.8-meter) can offer. 

One of the few 50 footers (15.24 meters) that can be sailed by just one person (many would of course disagree on this).

The Catana 50 is a catamaran worthy of an overseas journey. Its size adds to its stability on the open waters and its ability to sail straight through the choppy ocean and windy conditions. 

The Catana is also incredibly spacious on the inside, with substantial cabins and showers. The biggest downside to the Catana 50 is its price, as it’s much more expensive than most of its competitors. 

Catana also holds up well against some of the fastest cruising cats out there, here’s a list of the fastest cruisers if you are interested in that.

However, if you can find a gently-used Catana 50, you can rest assured that this boat will last! 

The Dolphin 42 is unique because of the use of daggerboards instead of fixed keels. This upgrade means that the boat has some pretty decent upwind performance while at the same time being faster downwind.

Centerboards and daggerboards offer some interesting downsides compared to mini keels. This is an interesting discussion and I suggest you read another one of my articles if you want to deepen your knowledge a little.

These catamarans are some of the lightest on the market. Not many Dolphins were made, so they are relatively hard to find. However, if you want a small, lightweight boat capable of going great distances, the Dolphin 42 is an excellent choice. 

Fountaine Pajot Belize 43

The Fountaine Pajot Belize is another well-built cruising yacht. Its core is made of foam instead of balsa, which reduces the risk of structural damage due to a rotten core in case of water intrusion. 

The design of Belize offers many options for customizability, with large open spaces and a combined saloon, navigation, and dinette area. 

There are two styles of Belize catamarans for sleeping quarters. You can either purchase a boat with an entire primary suite on one hull or one with two cabins in each hull. The first option is great if you are sailing the world alone and not expecting many guests, as it increases the storage capacity. 

Understanding what factors to consider when getting a cat can be hard, there are just so many of them (such as the daggerboard discussion above), I have tried to compile some of the most important in this article .

The boat also has wraparound windows to increase the sense of space in the galley. 

Fountaine Pajot Lucia 40

Fountaine Pajot is one of the best sailboat manufacturers existing today, as their boats are well made and highly versatile. The Lucia 40 is no exception – it’s a smaller boat but has a lot of room for moving around and on-board living. 

The living area is remarkably spacious on this catamaran for its size. 

The galley and lounge easily accommodate 6+people. The Lucia 40 doesn’t disappoint when it comes to sailing either, as the narrow hulls slice through choppy waters with ease. 

Most catamarans today are built to withstand rough weather but that doesn’t matter as much if the crew isn’t up for the task, I firmly believe that the most important thing a boat should consist of, is knowledge. Therefore taking online courses ( two free here ) or reading books ( my favorites here ) is imperative.

Gemini 105M

Gemini’s boats have been on the market for years and are solidly built for cruising. This boat is one of the most popular ever made, I personally would consider something different for offshore cruising, but since it has such a good reputation, I felt I had to add it to the list.

If you want to understand why I am hesitant to take this boat around the world, I recommend you read my article: What are trampolines on a catamaran?

The Gunboat 62 is a great catamaran and set the standards for the rest of the impressive Gunboat lineup. It’s sleek and spacious while being robust and capable of transatlantic journeys. You can easily travel the world in a Gunboat 62 with several people and not feel cramped. 

The yacht was made for speed and power and remains one of the fastest catamarans on the market, even rivaling the newer Gunboat models.  GABO

Although the earlier models of the Gunboat 62 weren’t designed for a lot of cargo, you can still find space for everything you need without compromise. 

Lagoon catamarans are known for their reliability and ease of use. If you are considering a catamaran for the first time and are unsure about the technicalities of sailing, a Lagoon boat is a great option. 

The Lagoon 380 is probably the smallest cruiser on this list, which makes it better suited for solo or couple sailing.  

When I go looking to buy something, whether it be a boat, campervan, or whatever, I create a checklist and classify all the things I want either by NEED or NICE to have.

I believe the Lagoon 380 to be sub-optimal for my NEEDS, even though it does check a lot of NICE boxes, there’s a step-by-step article on the NEED and NICE method here .

There are several cabin options available on the Lagoon 380, but if you’re sailing by yourself, you can settle for three cabins and a larger galley and living space. With a smaller cockpit and broader side decks, the Lagoon 380 packs a lot of practicality and ease of sailing into a more compact catamaran. 

If you like the idea of a Lagoon boat but want a little more space, the Lagoon 42 is the upgraded version of the Lagoon 380. With all of the same benefits, it comes with more space for cabins or storage, making it one of the best-selling Lagoons of all time. 

The Lagoon 42 is also a faster cruiser built for strength. While it’s not the fastest on the market, it works well in choppy waters and windy conditions, making it great for the beginning sailor to go on a more extended trip. 

Many people have completed an around-the-world sail with this ship.

Although there is a flybridge version, I would recommend the “open” version due to several factors, some including increased windage and a higher boom. More on flybridges pros and cons here .

For stability, safety, and durability, you can’t beat the Lagoon 42. 

The Leopard 45 performs better with less storage weight because of the relatively low bridge deck clearance. If the boat is fully loaded, you could experience some wave pounding. However, the cockpit is open and airy, with devices that block the sun and provide maximum comfort while sailing. 

The Leopard 45 is an incredibly beautiful boat,   and has a strong reputation for excellent build quality!

Leopard catamarans are one of my personal favorites, as such I have written an entire article about the brand, so if you want to understand its pros and cons then here is the link . Gabo

Designed in South Africa, it features a high rear arch for extra support and very smoothly connected decks. The galley is large and open, and most Leopards offer a four-cabin plan. If you are traveling with another person, this boat is an excellent option for you! 

The Manta 42 is another classic catamaran that you can buy used (at a decent price), as it is an incredibly seaworthy vessel. While still in production, the Manta was one of the most popular catamarans on the market. 

It is still in high demand amongst circumnavigators. Buying a used Manta 42 usually means that you inherit some of the previous owner’s boat upgrades! 

The Manta 42 also made it to my list of the 9 safest catamarans on the market ( link ).

This blue water cat can be sailed by one or two people, making it ideal for liveaboard couples or long-distance shorthanded sailing. The galley is in the saloon ( instead of in one of the hulls ), making the cabins below more spacious and better equipped. 

Overall, the Manta is well equipped for sailing around the world. 

Nautitech 44

Nautitech is an excellent brand of the catamaran, with several different designs per boat. The Nautitech 44 has a unique feature, you can have it with two options for steering: twin wheels or a single wheel.

The Nautitech 44 also features a cockpit on the same level as the saloon. The door between the two is more convenient than a hatch and dramatically reduces the risk of water damage during rain pour. 

This is also the same boat that aeroyacht president Gregor owns, he has offered some great insights into Nautitech in the book Catamarans (amazon link )

Outremer 45

Outremer is famous for being one of the fastest brands of catamarans on the market. If you need speed, the Outremer 45 might be the perfect choice for you. It has a top speed of 16 knots, which is higher than almost every other catamaran of its class. 

While the Outremer 45 is known for speed, it doesn’t compromise on the quality of living. 

You can settle into life on this boat with complete peace of mind. Even as a beginning sailor, the steering is simple and easy to use, and the autopilot is top of the line, so you’ll be able to sail across the ocean in an Outremer without issue. 

Privilege Serie 5

A French-designed catamaran, the Privilege Serie 5 is one of the most comfortable 50-foot (15 m) yachts available. The unique cabin layout includes the master cabin in the boat’s center instead of in one of the hulls. 

The Privilege Serie 5 is also incredibly easy to sail, despite its larger size. 

The sails and controls lead to the helm, where the raised deck makes it easy to see all around the deck. If you want to cross the ocean with a full crew then the Privilege Serie 5 might be perfect for you! 

Seawind 1000

The Seawind 1000 is the smallest boat on this list, measuring 33 feet (10 meters) long altogether. However, this doesn’t mean that it’s not livable. If you are sailing on your own or with a partner, there is more than enough space to live in the Seawind 1000, which includes the option of a centered cabin or two hull cabins. 

Because it’s small, the Seawind 1000 is easy to handle. The mast and sails are all manufactured for extra stability and ease of use. 

Overall, the Seawind 1000 is an excellent example of a simple, safe, and seaworthy catamaran. 

Note: since this is a small catamaran it will also be more sensitive to heavy weather so trip-planning becomes even more important.

The Voyage 44 is one of the oldest cats on this list, having had its hay-day in the mid-1990s. However, this also means that a used Voyage 44 will be cheaper than a newer boat. If you can find a Voyage with previous responsible owners, you will inherit any upgrades and fixes that they’ve made on top of a very seaworthy boat. 

The Voyage 44 has more storage and space than most cruisers of its size and is known for behaving very well in choppy waters. 

This catamaran does its job well while providing adequate space for cooking, sleeping, and living aboard. 

What To Look For in a Long-Distance Cruising Catamaran

If you are planning to sail around the world, you need to be very careful about which kind of catamaran you decide to use. Many of the things you want in a boat really comes down to personal preference, so be sure you know what design preferences you want before you start shopping! 

Size and Payload

The most important thing to consider when buying a catamaran is how much space and cargo you need because the larger the boats are, the bigger the payload it can handle. Decide how long you want the ship to be and how much you’re taking with you. 

It’s vital not to overload a catamaran, this will reduce performance and increase risk of unwanted behavior in heavy seas.

Cabin Placement  

Most catamarans have options for a “Maestro” cabin placement, where one entire hull is the master suite, and the other cabins are located on the opposite hull.

Cockpit and Protection From The Weather

Is the cockpit on the boat you’re looking at covered or open? This can make a difference on the high seas, especially during rainy weather. 

The size of the ship also can affect how many people you need as a crew. If you’re traveling by yourself or with one other person, you don’t want to buy a boat that needs a larger crew. 

Buying Used? 

If you don’t want to spend the money on a brand new catamaran, I don’t blame you. Several of the ships on this list are out of production and can only be found used. However, for circumnavigation, you do want a boat of high quality to keep you safe and dry until you make it to your destination.  

When buying a suitably used catamaran, it’s essential to look at the refit history of the boat more than the year it was made. Catamarans are sturdy, and the general design has been the same for at least the past decade. 

If you find a newer, larger, cheaper boat, you should look into its history. 

Your best bet to save money while buying a catamaran will be to buy an older, probably smaller boat with an excellent refit history and no serious issues. It will still be an investment, and a sturdy used catamaran will serve you well. 

Final Thoughts

No matter which catamaran you decide to buy for your journey, you’ll be able to sail safely and comfortably. Catamarans are great yachts for long-distance sailing, and the ships on this list are the best of the best. These brands are time-tested and ready to accompany you on an adventure around the world! 

Here are Some of My Favorite Catamaran Cruising Resources

Thank you for reading this article. I hope you found it helpful as you hopefully start your sailing adventures. Here are some resources that I use as a sailor that I hope you’ll also find helpful. These are affiliate links, so if you do decide to use any of them, I’ll earn a commission. But in all honesty, these are the exact things that I use and recommend to everyone, even my own family. Sailboats: If you’re looking for the best boat to suit your needs, I would recommend a catamaran. If you’re interested, I can show you the differences between catamarans and other types of sailboats .

Books:  For getting started, I really like  Cruising catamarans made easy . It is actually a textbook from the American sailing association; it is used to get a cruising catamaran certification. There are some other great books, and I have compiled a list of books about cruising catamarans that you will find useful.

Communication:  Being out on adventures, whether it be sailing or climbing mountains, good communications are essential to being safe. I recommend two things Google fi (incredibly simple cellular data all over the world) and Garmin inreach mini (for text and voice in remote areas without cell coverage)

Sailing courses: Online sailing courses are great for beginners starting out their sailing career; it’s an efficient way of learning the basics of navigation, throttle controls, and maritime safety. I suggest starting with two free courses from NauticEd .

This article will introduce the following:

The origins of the catamaran

Why is a catamaran a good choice, types of catamarans: catamarans may be categorized as follows, before you start…, how to rent a catamaran.

Catamarans were first built-in the 17th century by a fishing society called the Paravas in Tamil Nadu on the Northern shores of India. At first, the idea of two hulls was objected to by yacht manufacturers who had been used to models that have a single hull. Still, catamarans proved to have the best design amongst rapid vessels. This was due to their great stability and capacity. The main feature of these boats was the two-hulled design, which provided for more effective balance compared to other vessels of the era. The idea was first adopted by the British, and later it became widespread in the whole world. Evolution not only resulted in a change in relation to use but influenced and developed the designing and construction of boats to a great extent.

Types of catamarans: Design of catamarans

We distinguish between two types of catamarans in terms of design: the so-called Pontoon and the SWATH (Small Waterplane Area Twin Hull). The former is a small and compact boat that applies a floating technique in order to drive the two hulls. The latter is a large vessel which uses a method based on preserving the balance of the boat. They are ideal for areas where erratic waves are common. These larger types may be categorized as yachts. Today, a wide selection of catamarans are available, for instance, the motorized types, which are even more reliable.

Catamarans are available in several designs and sizes. Their size may vary, from 14 ft (4.5 m) to 100 ft (30.5 m) long models. Catamarans include sea cruisers with a weather deck, boats with cabins, etc. Besides the two hulls, they have a mast and, depending on the size, one or two sails. It may be a surprising fact that catamarans are considered standard yachts rather than sailboats.

Cruise catamarans

These boats are referred to as luxury catamarans or catamaran ferries. They provide the best service and luxury for passengers. The additional motors make these boats even more attractive for people. Having a shorter journey time, these ferries are ideal for passengers who want to spend more time in a city’s port. It must be noted, however, that luxurious catamarans only function within the country and not internationally. Catamaran cruisers offer all the best features of motor yachts. The Stena Voyager on the Irish Sea and the American Victoria Clipper IV are two of the most popular cruisers.

Sailing catamarans

Choose a route and get to know the destination better before leaving the port! Read the guides, search for information about a route or contact the charter agency which will provide you with recommended routes in a graphical form. When choosing a route, take into consideration the duration of your rental, and plan your programs accordingly! We recommend cruising for 3–6 hours a day while taking into account the fuel consumption that depends on the weather, and the size and type of the boat.

Boat rental is not as complicated as it first seems, especially if you have a good agent. There are always some basic questions arising during the rental process. The service provider can help you plan your cruising adventure. We have collected all the necessary information to make the process easier for you.

• First, you have to decide what type of boat you would like to rent. Certain models of catamarans are ideal for the whole family. This kind of journey can be a real adventure for the kids; a great example of active recreation.
• The number of people and the requirements for their comfort, the services provided on the deck and the need for a staff should all be considered.
• Make sure that you understood all the conditions and have received all the necessary information, including the duration, type and price of your rental.

Safety first!

Catamaran Construction – Hulls, Laminates, and Composites

• Post author By BJ Porter
• Post date October 15, 2020
• 4 Comments on Catamaran Construction – Hulls, Laminates, and Composites

It’s a given that catamarans are more sensitive to weight and loading than monohulls. Catamaran builders strive to build the lightest boats they can without sacrificing strength and stiffness, and have adapted new building techniques and materials to meet this target. Cutting weight allows more passengers and gear without sacrificing performance.

And the marketing materials reflect it–they load every review and website with polysyllabic technical jargon describing the design and production choices each builder made to deliver the best boat they can.

But when you’re reading a brochure and you come across phrases like “ hand laid bidirectional GRP ” or “ vacuumed bagged e-glass with vinylester resin over a Divinycell core ” do you know what that really means?

All modern production catamarans are made with “FRP” construction (for Fiber Reinforced Polymer). Composites aren’t new–it’s just using materials together to strengthen the whole assembly. Straw was added to bricks centuries ago, and steel reinforced concrete is a staple of construction over the last century. For boats, it’s the use of stranded fibers and cured resins which make FRP different.

The term “FRP” doesn’t get into the technical detail of which fibers and which plastics, and how they’re put together to build your hull. There’s a wide variety of fiber types which can be stranded, woven, chopped or sprayed in a varied of patterns then combined with several types of resins to make hulls with different characteristics.

Some FRP techniques produce lighter, stronger shapes, while others are quicker to build and less expensive to produce. The choice of technique is a function of many factors, from the number of hulls and parts to be built, the type of parts, the budget for the project, and many design specific requirements for weight and strength.

1. FRP Basics

The principle behind all FRP construction is the same – you lay our fibers in the shape you need, then saturate them with resin, removing all the air and voids you can. Resin is left to cure, then the piece is ready to finish and use.

The reality is more complex, since building a boat isn’t like making a flat board or a simple door. You’ve got a complex shape with a designed set of curves to build. “Tooling” is the set of shapes to make the boat parts; molds to cover with fiberglass to get the right shapes.

That’s what makes FRP so effective – you can make almost anything out of it. But to do so requires a lot of choices about what you need for the project at hand.

There isn’t a “best” all around material or technique choice for all jobs, and sometimes a lower cost technique or easier to work with material may be the better solution to the problem.

A. Fiber types

Fiber choices in the last few decades have expanded past the glass fibers used in the first mass produced boats in the 1960s. FRP construction wasn’t new even then, they built the first composite boats using modern fiberglass in the 1940s.

The major fibers used in marine construction fall into three categories – glass, aramids, and carbon. The primary differences are in the strength to weight ratios of the fibers, durability, elasticity, and cost. Some construction may use blends of fiber types to combine performance characteristics.

Glass – the most common material still, because of its low cost and versatility. The most common variety used in GRP (Glass Reinforced Polymer) is “E-glass” which refers to its strand size and mineral content. Other grades have different and sometimes better mechanical properties, but may be more expensive and less appropriate for boat building use. Fiber sizes run 10 to 25 microns for E-glass, though other grades may be smaller.

Brands like Leopard, Lagoon, and most higher production volume builders use E-glass.

Aramids – this includes brand names like Kevlar, Technora and Twaron. They have higher tensile strength than E-glass, and resistant abrasion and punctures. Kevlar is a common choice for bullet proof body armor, and can built a tough, lightweight hull. The materials can be difficult to work with, as it is very tough to cut the cloth. It is often blended with carbon fiber or other materials – Catana is known for using Twaron blends in hull construction.

Carbon – the ultimate in lightweight, strong construction material. Carbon fiber is the most expensive fiber, and is available in a variety of weights, grades and strengths. Fibers are smaller than glass – down to 5 Micron.

The lightest, most expensive hulls are made from carbon, but a catamaran builder may use carbon in places other than the hull to add strength and stiffness. Carbon boards, rudders, and reinforcing structures can enhance performance without driving the price of the boat beyond reach. Carbon is the fiber of choice for many custom builds, racing cats, and Gunboat.

B. Mats, Strands, Roving, Direction, and Weights

Fibers are woven into matting and cloth for construction. Depending on the application, different weights of cloth and cloth patterns and weaves may be more appropriate for the job.

Cloth weight refers to the weight per square yard (or meter) of the cloth. A square yard of nine ounce cloth weighs nine ounces. The heavier the cloth, the stronger it is in a laminate.

Fibers carry loads along their length, so cloth weaves have directionality to their strength. Most builders use several layers of cloth with different orientations to give good universal strength to hulls. Specific FRP applications with strict load-path requirements may have more unidirectional fiber layering – for example, a chainplate manufactured from carbon fiber may use unidirectional fiber.

Cloth – fiberglass cloth is commonly used on outer layers of composites. Cloth may have unidirectional or bidirectional strength. Bidirectional cloths have maximum load strengths in two perpendicular directions. Variations on weaves like a modified twill allow a more flexible cloth for better shaping around complex molds.

Mat – is omnidirectional strands of fiber compressed into a cloth. This is often held together with a resin soluble glue, which makes mat great at conforming to mold shapes without folding and bunching as it collapses when wetted. Because the strands do not align, fiber strength is the same in all directions.

Woven Roving – a heavier cloth made from larger bundles of strands. Woven roving allows for quicker buildup of material and strand weight.

Most FRP layups include multiple layers of different cloth and mat. Finished layers may be finer cloth over courser cloth, over woven roving and mat.

Three primary resins are in common use in marine construction – polyester , vinylester , and epoxy . All resins have materials safety concerns and require care in their use and handling.

Polyester is the least expensive and requires breathing protection because of the VOC emission (Volatile Organic Compounds…nasty, smelly fumes). It doesn’t have good bonding/gluing capability, and should only be used with glass fibers for structural building. Some polyester resins are referred to as “isophthalic” resins.

Vinylester is chemically similar to a hybrid of polyester and epoxy, and performs best with fiberglass. It shouldn’t be used in high strength applications with carbon or aramid fibers. It has some adhesive qualities which polyester lacks, it shrinks less during curing, and has better impact resistance.

The added strength of vinylester coupled with increased water resistance makes it an attractive option for many catamaran builders. It costs less than epoxy, but still has better performance than polyester.

Epoxy is the most expensive, but is three times the strength of the others. It offers the best adhesion and the only resin for building structural elements with carbon and aramid. It resists water intrusion better than the other resins, resists blisters, emits no VOCs, and shrinks less. The major drawback is it is more brittle if it takes an impact.

While epoxy is “the best” in terms of strength and ease of building, there are many applications where other resins are appropriate. Budget is a big driver – a boat made from E-Glass doesn’t need epoxy resin, and considerable cost savings to meet a construction price target may drive the choice.

They can build quality boats from all material combinations, but price and performance will drive materials choices to keep some boats more affordable.

2. Cored Construction

What’s the best way to make fiberglass strong? To a point, you can make it thicker. As it gets thicker, it gets heavier. A hollow shape can take more compressive load than a solid one of the same weight, and the same principle applies to fiberglass construction.

Consider an I-Beam used in building construction. It has the same strength (or more) as a solid rectangular beam of similar mass. The compressive load on the beam is supported by the outside edges of the material, the metal in the middle doesn’t contribute much to the strength. So we can remove metal to get the “I” shape while still keeping those sides rigid, making a lighter girder with less material.

The same principle applies to cored construction with fiberglass. Making a sandwich of two layers of fiberglass with a light core between them allows for the greater strength with weight savings.

There are drawbacks – the biggest risk is damage which breaks the skin, which can let water into the core. Earlier cored construction used materials prone to saturation and rot if they got wet. Some builders opt to do cored construction above the waterline and solid below to minimize some of these risks.

But the advantages in weight savings and increased stiffness offset the drawbacks, and there may be a few other side effects like sound and temperature insulation. Like resins and fibers, core materials offer distinct advantages, disadvantages and price points.

Most builders have adopted a hybrid approach, building solid hulls below the waterline, and cored hulls and decks above. This gives a balance of weight and safety.

A. Balsa Core

Balsa is light and inexpensive. The first cored construction used balsa, but it has the disadvantage of being wood. As a natural material, if it gets wet it can rot and break down. Builders use “end grain” balsa – shorter cross cut sections – to prevent wicking of water if there is an intrusion.

B. Foam Core

Closed cell foam cores give good strength to weight savings while minimizing water intrusion. If you get water in the core, it won’t spread very far. Divinycell is a popular PVC foam core, though there are several choices with different densities and compressive strengths.

Some foam cores are not suitable for heat treatment, but infused or vacuum bagged boats like the Outremer and PDQ do well with it.

C. Honeycomb

Honeycomb cores are often the most expensive, but also give some of the best strength to weight ratios. Honeycombed cells made from resin cured aramid papers are some of the best, but also among the most costly. They offer good stiffness, but can be hard to shape. Aluminum and other resin-infused papers are other core materials builders can choose from.

3. Construction and Resin

When building a hull, there are optimal ratios of fiber to resin saturation for target strength and weight. Too little resin and you may not have enough strength (or worse, voids and gaps), and too much, and you’re just adding weight without adding strength. Resins are also a significant material cost in building the boat, so over application not only increases weight but adds cost.

There are many ways to assemble the cores, fibers and resins to build a finished laminate hull – we’re addressing the most common in boat building. Each approach has strengths and limitations, and an impact on the bottom-line cost to build the boat. Any voids or air pockets in the laminate can be disastrous; these techniques have been developed to increase saturation and reduce the risk of voids.

A. Hand Layup / Open Molding

As the name implies, this is the application of resin by hand to cloth as it’s laid into a mold. Wetting is done with a brush, and the laminate is rolled out to remove any air pockets and voids. This is the simplest way to lay up fiberglass, but also the least precise and consistent and will use the most resin.

Skilled craftsmen have built some of the finest vessels in the world this way. Though it’s more popular with monohulls, which are less sensitive to weight, many catamarans built with hand layups on open molds are still out cruising and performing well.

B. Spraying

Using chopped-strand fiber mixed with resin, a “chopper gun” can spray the mixture into a mold to lay down the composite. A consistent thickness can be difficult, but this is a low cost construction technique which makes a very resin-rich laminate. Using sprayed fibers gives lower strength in all directions compared to meticulously laid down mat and bi-directional cloth. But it is a quick technique popular with mass produced, smaller boats.

It is an excellent technique for parts with complex geometry where weight is not an issue, but you will not see it often in catamaran construction. It’s heavy with resin without any resultant increase in strength.

C. Vacuum Bagging (Wet layup)

When an open molded component has been laid up and wetted with resin, vacuum bagging takes the process a step further. After the wetting is complete, air tight plastic bagging is secured around the wetted area, and the air is pumped out of the bag. The vacuum pulls excess resin out and collapses air pockets.

The goal is to get thorough wetting and produce as strong a laminate as possible without excess resin. Knysa and Leopard are two builders that use vacuum bagging on their hulls to reduce weight.

D. Resin Infusion

For resin infusion the cloth, matting and core is laid in place dry, then sealed in an air-tight bag. A vacuum pump attaches to one side of the bag, and on the other a feed for resin. The vacuum sucks the air out of the dry cloth stack, then pulls the resin through the stack, infusing and wetting it.

Resin infusion, when done right, gives the lightest, strongest laminates with no voids and the minimum resin weight for maximum strength. SCRIMP is a variant of the resin infusion process used by some builders, including TPI which build many early Lagoon cats.

E. Pre-preg

Using pre-preg (for “Pre Impregnated”) cloth for your laminating gets rid of the resin bucket. They manufacture cloth with a partially catalyzed resin pressed into it, then it’s chilled or frozen to stop the curing process. There is no need for seperately mixed resins, and there’s no worry your resin might “go off” and harden before you’re done wetting the cloth. Instead, the cloth is assembled, vacuumed, then heated to kick off the curing process.

There are both advantages and disadvantages to using pre-preg for your laminate work. The big disadvantage is the cost; it is most expensive material to use. You also need to chill and store the cloth until you need it, though some can be at room temperature for a couple of weeks without kicking off. And you need an oven which requires some clever tricks if you’re building a forty or fifty foot boat.

But the strength to weight ratio will always be perfect. High tech honeycomb cores are best suited to pre-preg lamination, and without racing against resin cure times, you can ensure perfect cloth placement and precise layout in the build process.

The primary use for pre-preg in boating is high performance race boats. With catamarans, pre-preg may be used high load parts, like Gunboat does for foils and rudders.

4. Industry Examples

Across the catamaran building industry you’ll find almost all the above techniques and materials used, though some are less common. You aren’t likely to find chopped strand sprayed layups in ocean going cats, and hand layups can lead to heavier hulls than weight sensitive catamaran designers prefer. Most manufacturers have moved to vacuum bagging or resin infusion, with a few of the highest end boats using pre-preg for key components.

Built by Robertson & Caine in South Africa, the hull material is vacuum bagged, end-grain balsa-cored E-glass with polyester.

Hand laid, bagged vinylester over an Airex foam core in the hulls.

Earlier Prout catamarans like the Snowgoose 34 featured hand laid solid FRP hulls and decks. Over time they switched to foam or balsa cores for decks and above the waterline.

Older PDQ boats were made from vacuum bagged vinylester – solid below the waterline and cored with CoreCell foam above the waterline and in decks. Newer PDQ models switched to epoxy resin.

All glass is vacuum bagged. Below the waterline is solid E-glass and vinylester. The rest is unidirectional, bidirectional, and triaxial cloths over a Nida-Core polypropylene honeycomb core with isophthalic and vinylester resins.

The Gemini cats are built with a solid hand layup of woven roving and fiberglass mat and polyester resin. Decks are cored with end grain balsa. The Gemini 3200 introduced vinylester resin into the layup to prevent blistering.

Older Lagoons were SCRIMP infused vinylester with and end grain balsa core above the waterline and in the decks.

Newer Lagoon catamarans use polyester and vinylester resins, also infused with balsa cores above the waterline and solid below.

With a carbon fiber inner skin, Catana also uses Twaron aramid fibers in the sandwiched hull over a foam core.

Fontaine Pajot

Primary hull construction is resin-infused vinylester with a balsa cored hull and deck.

Beneath the waterline, Outremer uses a single layer, solid vinylester laminate for safety. The hulls and deck are vinylester with a Divinycell foam core. They stiffen certain components with carbon for rigidity and durability.

Gunboat hulls are epoxy infused carbon fiber with a Nomex honeycomb core. They build dagger boards and other high load components with pre-preg carbon.
