When laying the fiberglass and applying epoxy, it is important to take your time and be precise.

Fiberglass and epoxy are key components of a catamaran boat, as they provide the strength and waterproofing necessary to keep the boat afloat.

Start by laying the fiberglass over the frame of the boat.

Make sure to cut the fiberglass to size and overlap the edges for a strong seal.

Once the fiberglass is in place, mix the epoxy and begin to apply it.

It is important to apply the epoxy in a thin, even layer to ensure a proper seal.

Make sure to move the epoxy around to get it into all the nooks and crannies of the boat.

Allow the epoxy to cure and then you can begin to add the finishing touches.

Finishing Touches

Once the frame of the catamaran boat is built, it is time to add the finishing touches.

This includes adding the necessary hardware, painting, and rigging the boat.

Add the appropriate hinges, screws, and nails to the frame.

Make sure that the screws and nails are the correct size and do not exceed the recommended load capacity of the frame.

Painting: Once the hardware is added, it is time to paint the boat.

Choose a paint that is suitable for the materials used in the construction.

Make sure that the paint is applied evenly and that the frame is completely dry before applying the next coat.

Rigging: The last step is to rig the boat.

This involves attaching the sails, running rigging, and standing rigging to the masts and booms.

Make sure that the rigging is properly tensioned and secured.

Once all of these steps are complete, your catamaran boat is ready to sail.

Hardware & Paint

The last step in building a catamaran boat is to add the hardware and paint.

This step is often the most rewarding, as it is the finishing touch.

Depending on the design of your boat, there are various types of hardware you may need.

Some of the most common items are cleats, winches, fasteners, and decking.

After selecting the required hardware, you will need to install them on the boat.

It is important to use the correct type of screws and bolts, and to secure them tightly.

Once the hardware is installed, it is time to apply the paint.

The type of paint and color you choose will depend on the design of your boat.

It is important to use a high-quality marine grade paint that is designed to handle the extreme environment of the ocean.

If you are up to the challenge, you can add some custom artwork or detail to your catamaran boat.

Adding the hardware and paint is the final step in building a catamaran boat.

With patience and attention to detail, you can create a beautiful and unique boat that will last for many years.

Be sure to take your time and enjoy the process of constructing your own boat.

Once you have finished the frame, fiberglass, and epoxy of your catamaran boat, you will need to move onto the rigging.

This is a crucial step in the construction process, as it will keep your boat safe and secure on the water.

When rigging a catamaran, there are a few key components that must be taken into account.

First, you will need to determine the type of rigging you will be using.

Typically, catamarans use a combination of standing and running rigging.

Standing rigging consists of cables and lines that stay in a fixed position to provide stability and strength to the boat, while running rigging consists of lines that are used to adjust the sail and mainsheet.

Additionally, you will need to choose the right type of rope and hardware for your rigging setup.

The rope should be strong and durable, and the hardware should be made of stainless steel and be corrosion-resistant.

Once you have chosen the type of rigging and hardware, you can start assembling the rigging lines.

This process involves carefully measuring and cutting the lines to the proper lengths, and then attaching them to the mast and boom.

Depending on the type of rigging setup, you may also need to attach the lines to the hulls and deck.

It is important to inspect the rigging lines and hardware regularly to ensure that everything is secure and in proper working order.

Rigging a catamaran boat can seem like a daunting task, but it is essential for the safety and comfort of your vessel.

With the right tools, materials, and attention to detail, you can successfully and safely rig your catamaran boat.

Final Thoughts

Building a catamaran boat is a rewarding experience that requires patience and attention to detail.

With the right plan, materials, and steps, you can build your own boat in no time.

Now that you know the basics of how to build a catamaran boat, why not grab your tools and get started on your very own project? With the right motivation and dedication, you can make your dream of owning a catamaran boat a reality.

Exploring the Benefits of Small Sailing Catamarans: Speed, Stability, and More

Sailing enthusiasts are constantly seeking thrill and adventure on the open waters. Whether you’re an experienced sailor or a beginner heading out for your first voyage, choosing the right sailing vessel can make all the difference in your experience. While monohulls have been the traditional choice for many sailors, small sailing catamarans have gained immense popularity in recent years. These sleek and nimble vessels offer a host of benefits that make them an attractive option for any sailing enthusiast .

One of the most enticing advantages of small sailing catamarans is their exceptional speed. These multi-hulled vessels are designed to slice through water with minimal drag, allowing them to achieve impressive speeds even in light winds. Unlike their monohull counterparts, which rely heavily on heeling to generate forward momentum, catamarans can reach high velocities while maintaining stability and comfort.

Whether you’re looking for a thrilling race on the open ocean or a relaxed day trip exploring coastal bays and coves, these boats are up for any challenge. Their shallow draft enables them to access shallow waters or anchor close to shorelines that may be inaccessible to larger vessels. This versatility makes small sailing catamarans not only suitable for seasoned sailors but also an ideal choice for families or those new to sailing.

In conclusion, the benefits of small sailing catamarans are undeniable. From their remarkable speed and stability to their ease of handling and spaciousness onboard, these vessels offer an unmatched sailing experience.

Time For a Catamaran Adventure

Isn't Time For Yours?

Building Your Own Catamaran

Building your own catamaran is another option to getting into your own boat. In this page we will go over the advantages, considerations, and a detailed history and journal of our boat-building adventure with Light Wave . We hope this will give you a clear picture of what lies ahead if you go this route, including:

• Construction methods
• 9 essential design features
• Review of the four leading catamaran designers for home builders
• Construction times
• Budget: How much did it cost to build a basic cruising catamaran?
• Layout of our catamaran, LightWave , and lots of pictures
• Carllie’s article from September 2000 Multihulls Magazine: “The Boat Builder’s Wife “
• Equipment outfitting
• Radio and communication outfitting
• Dinghy selection and considerations
• Having a boat custom-built for you

Because of the huge dollars needed to buy a new or even a used catamaran, we would never have gotten a catamaran if we hadn’t built it ourselves.

Let’s start by saying that building any type of larger boat, especially a catamaran, can be one of the most intellectually and physically challenging things you will ever do.

It has been said that building a large boat is the closest a man can come to giving birth to a baby. In other words there is going to some discomfort and pain along the way; you will question yourself on whether this was such a good idea; it’s very difficult to reverse the decision; and though friends will support you, you will be on your own most of the time with your significant other if he/she is game.

Know your boat

You will intimately know every part of your boat. You will know where every wire, hose, bolt, bulkhead, rib, and support is because you installed them!

Pride of ownership

We have often thought what it would be like to just buy a boat from a manufacturer, and know that while owners who have spent a lot of cash (or future life to pay off the lien) their often possessive and competing-with-the Joneses could not begin to compare to our quiet glow of happiness and akinship we feel with Light Wave .

Our boat is like part of the family. So much time was spent on her that we have a major emotional investment. Every time we see our vessel – from a distance at anchor or approaching her in our marina, we say, “What a pretty boat! I can’t believe we built it!” Then that sense of accomplishment settles back in and we feel we have indeed earned the privilege of all of the beautiful experiences we have had sailing, cruising, exploring the beautiful BC Coast and much further a field (or should we say “an ocean”?).

You will be able to pay for the materials as you go and “donate” your time to the cause.

Get a newer design

Many of the production boats that are out there are designs of many years ago because the manufactures have to recoup their capital investment on the mold and production setup. When you build your own you have much newer designs to draw from.

Details on Our Boat Building Adventure

We had sailed our first boat Wave Dancer for five years and had many adventures on the British Columbia coast. In May 1996, I had just returned from a little one-week solo trip in the Gulf Islands of BC when I bought the book, The Cruising Multihull by Chris White (Future link to book review on our web site).

This is the book that got me going (Carllie was not yet convinced). I must have read it a half dozen times over the next 6 months, each time becoming more convinced that this was the way to go for our next boat. It was really still pre-internet web site days so I wrote to all the designers that were listed in the back of the book. Over the next several weeks packages of information started appearing in the mailbox (there is just something about getting packages in the mail – I guess it’s the anticipation). I would pour over these preliminary printed pages with pictures and accommodation layouts. Next, I put a few dollars down to buy the information packages and study plans from the top prospects.

I waited patiently for the study plans. It was like the night before Christmas when I was kid. Oooh the wait! Finally they came, and again I carefully scrutinized the next level of detail. Things were getting a little more serious. The top contenders were:

• Richard Woods
• Chris White
• James Wharram

Click here to read my comments and reviews on their catamaran designs as well as those of Jeff Schionning.

I remember initially drooling over the Atlantic 42 by Chris White, still one of my favorite designs. It seemed to be so seaworthy (by the way if I run into about $800,000 USD any time soon, I am going to buy an Atlantic 55). The most important piece of advice that came out of the material was from Richard Woods:

“Build the smallest boat you‘d be happy with it.”

Axiom #1: The hours to build a catamaran is in almost in direct proportion to its weight.

Which brings us to Axiom #2:

Axiom #2: It takes about 1 hour to create 1 pound of finished boat.

In our case we spent 3,500 hours ( click here for full details on the construction hours ) to build a 4,000 lb. boat (just a little less than 0.9 hours per pound). If a boat’s empty weight is 8,000 lbs., it will probably take about 6,000 hours to build.

When you think about it, you can only mix and handle so much material per hour. More boat weight, more material, more hours. Sure there are some economies of scale on a bigger boat, but usually the systems become more complex and these take longer to install.

This decision process took 8 months and I figured we’d launch in 6 months. It was now January of 1997. Little did we know it would be 26 months and 3,500 hours between the two of us until we launched on June 5, 1999. We ordered the full plans and we were off and running.

We were ready to build, but where would we start the process? First of all, we live in a tiny 480 sq. ft. apartment in Vancouver. Back-yard building wasn’t exactly an option so I found a small garage nearby that we rented for 5 months.

After about 4 months in the garage, I had made all the small parts and it was time to build the hulls. This meant that we had to go larger facilities. We found space at Shelter Island Marina and Boatyard in Richmond. This is the biggest boat yard in the Vancouver area with dozens of commercial and private projects, big and small, under way.

We were out of money by then, so we sold our first boat so we could buy resin and fiberglass. It was a traumatic time as we said goodbye to our beloved Wave Dancer . We were now committed. We than had all the foam for the hull cores, barrels of resin, and huge rolls of matting and roving needed for the fiberglass skins delivered to our “domed stadium”. We kicked ourselves many times that we didn’t take a picture of this raw material stacked in one corner of the empty shed, so we could later show “before” and “after” photos. It was time to build the hulls.

Over the next several months we proceed to join the hulls with the beams I had built in the garage, and then to install the cuddy cabin, cockpit, and decks. By the spring of 1998, it was staring to look like a catamaran. Through the spring and summer of 1998, we continued with the major structural components: mini-keels, hatches, stairs, and interior. Then we went on to the very laborious work of fairing the boat before painting. Don’t under estimate that job!

By October 1998 we were ready to prime the boat and start painting. I really thought this would go quickly. I forgot that I would have to do two more complete sandings to sand off and finish the two layers of primer application. In addition we had to fill countless pinholes – a laborious process somewhat like hiking up a mountain – each time you get to what you think is the top, you see another summit!

The boat seemed to get bigger and bigger. Believe me, there is a lot of surface area on a catamaran. I clearly remember that last sanding: I had reached the end of my physical and mental endurance – I was exhausted. I was ready to move on to the next phase – any phase but more sanding!

We now started spray-painting the hulls bright yellow. It was around this time we decided on our boat name of Light Wave . The painting took over a month: the hulls being the easy part, it was the topsides, the nonskid, and all the masking and prep that seemed to take forever. Happily, the worst of the dust was gone.

By March 1999 we were in the home stretch. The center bridge deck cabin was completed so we took a week off from our paid jobs and lived on the boat in the shed so we could work all day and not waste time commuting. March, April and May were frantic months as we finished all the final touches: engine installation, rudders, windows, deck fittings, electrical, plumbing, mast, and rigging. See our outfitting page (for more details on what we picked and why, and things we would do differently now.

Initially, our electronic systems were relatively basic but included GPS and autopilot see the following link for all our electronic outfitting choices and reasoning for more details.

It was May 22, 1999 and we decided that Saturday, June 5th would be “Launch Day” so we could send invitations to all of our friends. On the Friday night before Launch Day, we still had a number of final things to do, many of them outside. Unfortunately it was pouring rain. We were tired and very wet but the boat had to go into the water next day so we persevered on till everything was ready.

The moment of truth came as Light Wave was lowered into the water. While still in the slings of the Travelift, I jumped aboard to check for leaks. Of course there weren’t any! More food and laughs and tours of the boat for all attending. It was a great day.

Emotionally drained that night, we slept in Light Wave in the water for the first time. It was another week before we actually went out for our first trip as we had to sell the shed, setup sails, and install some final deck hardware.

To sum it up, building a catamaran was a great experience. We learned a lot. Carllie and I grew closer together through it all. We had a great time doing it. We had a beautiful catamaran to show for it. Now it was time for a catamaran adventure !

More than ever before, sailing fans are gaining an interest in catamaran layouts and designs that define performance. Many others are also looking into either buying a cruising catamaran or designing and building one. While building a catamaran is no piece of cake, this article shows you how to create the perfect cruising catamaran layout. 

To create the perfect catamaran layout, carefully consider factors like a good hull design, optimal helm station placement, boat stability, and adequate load-carrying capacity. Excellent galley positioning, ease of handling, and spacious living and sleeping quarters are also crucial. 

The modern cruising catamaran is a far cry from the simple Polynesian double canoe of old. That’s because structural innovations and new composite materials have resulted in multihulls with impressive cruising abilities. Keep reading to learn more about exceptional catamaran layouts.  

The Changing Trends in Catamaran Designs

The early cruising catamaran designs resulted in boats that could sail much faster than traditional sailing boats. In addition, they could glide with ease in shallow waters and required less wind and crew. Unfortunately, these cruising cats were heavy, had small, cramped interiors, and boasted somewhat challenging handling abilities. 

Today’s cruising catamarans are different. They boast the utmost comfort, high speeds, and the safety of a well-designed cruising yacht. They are also more exciting, visually appealing, deliver the smoothest of rides, and sport more spacious interiors. 

Have a look at the below video showcasing the top ten cruising catamarans:

Features To Look Out for in Catamaran Design Layouts

Cruising catamaran designers understand what most sailors look for in a cruising vessel. They, therefore, design cruising multihulls that address these pertinent issues and more. Some of the features you might want to consider having in your dream boat include the following:

• Responsive performance. Outstanding performance allows for pleasurable cruising and ensures your safety since you have more options during difficult weather.
• Excellent load-carrying ability . This allows you to have an extended cruising vacation or ocean crossing.
• Boat stability . Go for lightweight, robust construction, which results in a lot of buoyancy.
• A low center of gravity for smooth rides and enhanced performance. Centering weight around a low center of gravity improves the overall sailing quality, reduces pitching movement and reduces the risk of capsizing .
• Adequate bridgedeck clearance to reduce slamming and provide better performance in rough conditions. A high bridgedeck also means less noise and slapping action from the waves hitting the boat bottom, thus ensuring a quieter, smoother ride.
• Comfortable sailing. To enjoy a quality life on board, you need comfort while at sea. Thus, elements like gentle movement, no creaks or groans, no bridgedeck slamming, and minimal pitching are essential for quality, peaceful and restful sleep.  

Now that you know what a cutting-edge catamaran features, let’s look at how to create the perfect cruising catamaran layout.  

Build a Larger-Sized Catamaran

The early catamarans ranged between 36-42 feet (10.9-12.8m). At the time, this appeared to be a good size in terms of safety and ease of handling. However, the boats were heavy, and the additional drag and displacement adversely affected their performance and windward ability. 

It’s now possible to make the new generation catamarans lighter, larger, and more spacious with excellent power-to-weight features. The current trend is larger-sized catamarans in the 45-50 feet (13.7- 15.2) range. Composite engineering and technologically advanced equipment such as furling systems, electric winches, and autopilot make it easier for a smaller crew to sail larger boats with confidence. And to do so without compromising safety or stability. 

Get the Best Catamaran Hull Design

A cruising catamaran’s performance depends on three main aspects; its length, the sail area, and the boat’s weight. Long boats are generally fast. A light boat with more sail area is also faster than a heavier boat with less sail area. In other words, you can make a multihull faster by making it longer, lighter, or adding more sail.

However, there are exceptions to this rule; a boat with too much sail area is more likely to capsize if there are brisk winds. Also, if the boat’s design makes it too light, it’ll be unable to handle much punishment, while a hull design that’s too slim would make the vessel incapable of carrying any significant loads. But that’s not all; if the boat is too long or too large, it’ll become grossly exorbitant. Narrow hull shape might also mean smaller cabins.

Nonetheless, these three factors alone are not enough to determine a cruising catamaran’s performance. While faster boats boast finer hulls, the wetted surface area tends to increase as fineness increases; thus, fine hulls end up becoming less fast in low wind speeds. Also, very wide hulls mean a reduction in actual performance.

The Prismatic Coefficient (Cp), a measure of how full the ends of the hull get, is the most essential design hull shape factor for any catamaran. A high Cp equals high speeds, although you can still use a lower Cp if you have fine hulls. Nevertheless, the key to a good Catamaran design is a higher Cp for fast sailing. 

To achieve a high Cp, there are several things you can do: 

• Fit bulb bows . Unfortunately, the bulb bows tend to slam in a seaway when you do this.
• Have an extensive planning aft section . However, this can increase the wetted surface area, WSA and lead to additional challenges. 
• Flatten out the hull rocker and add a bustle aft. This helps to add displacement aft. 

Build Convertible Main Living Spaces

The open cockpit is now a thing of the past. Instead, pioneering designers for catamaran manufacturers like Nautitech, Gunboat, and Catana now replace traditional-style salons, cockpits, and cabins with spacious indoor and outdoor living spaces. The concept involves merging separate saloon and cockpit areas with duplicate lounge spaces and the use of hard-wearing composite materials. 

You can also design the cabin to suit your preferences. You may decide to add a cabin or remove one, add a bathroom, have the forward berth in the hull or on the wing deck.

• The design enhancements boost usable space while opening up the living areas.
• It reduces time and costs for interior maintenance and cleaning. 
• Large windows bring in more light, increasing visibility. 
• Luxurious, spacious, and airy owners’ cabins provide more comfortable living space. 

Bulkhead Helm Stations vs. Twin Stern Steering

Many catamaran owners have traditionally preferred bulkhead steering. This helm position remains popular, but twin stern steering positions come with more advantages since they provide greater sails visibility. The twin stern positions are also best suited for racing or day sailing since they often lack adequate protection for extended cruising. 

Exposed helms are not ideal for a long ocean passage. Go for a safe, secure, and well-protected helm station that provides good visibility and comfortable space for long watches. Again, it’s best to have all control lines at the helm to establish a static control station. Also, have all push-button-controlled winches, instruments, windlass, and autopilot prominently located inside the cockpit. 

• Twin stern steering positions give you a better view of the sails
• You get a better feel for overall sailing conditions.
• Twin stern steering positions lack the necessary protection for extended cruising. 

Go for the Flybridge Design

The flybridge design is appealing because it offers excellent visibility, more comfort, and additional entertainment and lounging space for everyone on board. Unfortunately for smaller boats – those below 50 feet (15.24m), there is minimal protection from the elements. As such, you might want to consider adding enclosures to offer protection. The flybridge, thus the helm, remains cut off from the vessel, which makes communicating with the crew a challenge. 

• It provides great visibility.
• It offers comfortable spacing. 
• It might be unsafe to move from the cockpit to the flybridge in bad weather.
• It isn’t easy to communicate with the crew.

Daggerboards vs. Fixed Keels

Average cruising catamarans typically utilize fixed keels while high-performance cats have daggerboards . Fixed keels allow you to beach your catamaran easily, and your hull remains intact if a collision occurs. While you lose some angle when sailing upwind, you gain more interior space in the hulls that you can put to good use.

Daggerboards are essential in a performance cruising catamaran since they guarantee that the boat delivers good upwind sailing, including during difficult situations. During long passages, they allow you to point better upwind though the drawback is that they consume much interior space within the cruising catamaran’s hulls.

Since flying on foils ( hydrofoils ) isn’t that practical on cruising catamarans, designers of larger-sized boats have also come up with modified daggerboards. These daggerboards produce lift and prevent leeway, too, thereby improving performance significantly, as seen with the Catana 59’s curved daggerboards. These foil-like daggerboards lift the boat ever so slightly upon reaching higher speeds, making it feel less heavy and much faster. 

At the end of the day, calculating the performance of a boat sailing in a wide range of varying seas and winds might not be easy – despite a daggerboard or fixed keel configuration. This is because upwind speed depends not only on the sails’ quality but also windage and the height of the bridgedeck beyond the water.

• The design innovations -curved daggerboards and hydrofoils- improve catamaran performance significantly.
• Daggerboards enable you to access otherwise inaccessible anchorages.
• Daggerboards take up hull space in the hulls of your vessel.

Galley Up vs. Galley Down

Galley layout are becoming more and more important as more people, including families, start sailing regularly. While at sea, your galley needs to be a safe place, well-ventilated, and functional. Everything should be well-thought-out for the sailor’s comfort, including handholds to make it safer to move around the boat. 

While the galley location can either be up the bridgedeck or down in the hull, galley up appears to be the most popular trend. This makes the galley the focal point of both the living space and entertainment areas.

If you have a family, this placement is ideal since you make your meals from the galley and get to spend most of your time here. Many cruising families and couples prefer this arrangement and find separating the galley down the hull unappealing. Besides, carrying hot food up and down the staircase is unsafe.

Still, galley down is ideal for charter boats since it offers a private cooking area and uses up hull space efficiently.  

• Having the galley on the bridgedeck is ideal for families and cruising couples.
• Placing the galley on a similar level with the serving area and cockpit is safer and less tiring.
• There’s better ventilation on the bridgedeck, making for comfortable cooking. 
• There’s less kitchen privacy galley up.
• On smaller catamarans, this layout can impact the size of the saloon seating area significantly.

Production Catamaran vs. Custom

The choice of either a production catamaran or a custom design might seem pretty straightforward. Production catamarans from major brands come backed by proven designs, dependable construction, solid warranties, and many years of experience. The catamarans are easy to service, source for parts, and most – particularly the owner’s versions – hold on to their value, making them much easier to resell. 

On their part, custom boats are fantastic in that you can tailor them to your exact needs. However, they might be more challenging to maintain or service. That’s because of parts unavailability and lack of construction knowledge.

Choose Quality Construction Materials

The best quality materials to use on your catamaran are both light and robust. While carbon fiber is great, plywood, plywood/epoxy, and strip-cedar are excellent materials too. What’s more, they are also affordable, so you don’t have to get too hung up on cutting-edge building materials. What matters is build quality; thus, a well-built plywood catamaran boat can last as long as a boat made from more high-tech materials. 

Combining various materials also helps combat some of the issues that plague plywood boats in terms of resale value. At times, the design tends to make the boats appear pretty dated.  

• Plywood and strip-cedar materials are affordable and provide excellent build quality. 
• Plywood boats may have a lower resale value than those built with modern materials.

Consider Ease of Handling

An important factor in handling a cruising catamaran is deck layout. Most cruising catamarans sailed short-handed , so if your boat has one helm, all lines should run back here to allow for a static control station for the entire boat. 

The other essential element is visibility from the helm. The 360 degrees of visibility while maneuvering, docking, or underway is crucial to your boat’s safety, as well as life and property. As such, you should be able to view both bows, or at least the pulpits and sterns, while standing at the helm. If not, you may have challenges handling the boat due to blind spots.

Consider the Load Carrying Capacity

A well-designed catamaran is enjoyable to sail in all weather conditions. It’s also much easier to handle than a monohull because of its widely spaced twin engines. But when you immerse extra hull depth, the vessel gets sluggish and moves slower, maneuvering in tight spots or when docking becomes more challenging. Furthermore, the hull submersion reduces bridge deck clearance, leading to hull slamming. 

To allow for adequate load carrying capacity, you need a design that provides a generous displacement. This helps to ensure that you maintain reasonable bridge deck clearance even when fully loaded. It also allows you to avoid digging big holes in the water as you drag your transoms. 

Displacement refers to the amount of buoyancy designed into the hulls, which essentially means that your boat will cruise better if its weight is less than your designed displacement.

Note that an overloaded catamaran not only loses out on performance but eventually, on safety too. To counter this, choose a lightweight catamaran with hulls bearing cored construction and interiors made of lightweight materials.  

Remember, when you go cruising, you will need to carry fuel, extra water, supplies, equipment, and amenities, translating into thousands of extra pounds. Therefore, try and avoid the following design errors to ensure that your catamaran has an adequate load-carrying capacity:

• Avoid putting in place too much accommodation space.
• Avoid building a heavy boat ‐ use low-tech construction materials.
• Avoid installing inboards in a small boat.
• Lightly constructed catamarans perform faster and carry more weight.
• Cored construction makes for a strong and stiff catamaran, thus enabling good performance.

Final Thoughts

A well-designed cruising catamaran is a joy to behold. Today’s modern technological advancements mean that you can buy or build a light but strong cruising catamaran. And as you can see from this article, there are many excellent cruising catamaran layouts that you can choose from. 

However, whichever layout you decide on needs to fit your sailing needs and purposes to ensure you remain comfortable and safe while at sea. Above all, ensure that you go for a vessel that you can handle with ease in all weather conditions.

Building Your Own Sailboat

Overseas radio network – building a sailboat.

• Why we built our boat
• Things to consider when building a boat

GARY FRETZ: Ahoy, mates! You’ve tuned into “Yachts: The Perfect Escape Vehicle”. This Gary Fretz and I have my co-hosts here today, Stephen and Estelle Cockcroft. You might be wondering why yachts makes the best escape solution. Well, it is because you can find live aboard yachts for $15,000, $15-million, and everywhere in between. They serve as your home and they provide inexpensive transportation around the world.

For a transcript of this podcast, click “read more” below. (Also, check out our Catamaran Buying Guide .)

Yes, it’s possible to sail around the world for next to nothing using windpower. And if you would like to know how to do that just stayed tuned.

Why We Built Our Own Boat

ESTELLE COCKCROFT: Hi, guys, today we are going to talk about new boats, used boats, building your own boat, and building your boat in a shipyard. We all know that we can’t find a perfect boat, but you can get it as close as possible when you do build your own boat or when you have it built by shipyards.

Stephen, you and I built our own boat, or you mostly, I suppose. But do you want to talk a little about what you experienced when you built your own boat?

STEPHEN COCKCROFT: Sure, you know in South Africa when we were getting…when we were putting our boat together, there wasn’t really the opportunity to go down to the local market dealer and buy a boat. Because in South Africa, the trend was for people to build their own boat in the backyard and so we followed the trend.

The percentage of people that finished their boats in the backyard is about 2% of everyone that starts them so you would drive around and see all these boats in the backyards and you would know that hey 2% of everyone is going to hit the water for various reasons.

GARY: Wait, why is that? That’s incredible.

STEPHEN: Well, you know, financial…a lot of guys will buy a boat. They’d buy maybe a hull and deck and bulkheads, and then they’d think, OK, well as I make money, I will put it together. The average time for someone to do one of these projects is actually 10 years. We were very lucky, you know, we had the financial ability to build constantly. And so we from start to finished build ours in 2 years.

You know, they are very custom boats and so you actually have to go and get a lot of input. What I used to do is drive around to the different brokers and tell them I was interested in buying a boat and specifically and I give them my brand of hull I had. And then I would go and say, “Well, this is great,” and take photographs like crazy. So I had about 1000 photographs of sister ships and that’s how we decided what to do inside the boat. There were no plans because we had to invent the whole thing from scratch.

What You Need to Build Your Own Boat

So building a boat, you need some pretty good technical ability. I wasn’t that good when we started but, believe me, after 2 years of hanging upside down in that boat every single spare minute I ever had you know I pretty much knew my boat and I pretty much knew how to fix it and how to build a boat.

The problem is the time and the time you dedicate to the boat. Sometimes I use to sit and wonder why I just didn’t buy a new boat. Also, there’s a lot of skill you can’t develop in the time that you need have to build the boat such as woodworking. So I had some experts and some cabinet makers and some really good carpenters that came in to assist with build of the boat. The end result was a beautiful monohull, 45-foot long. We launched her in Cape Town, you know. We sailed her up the eastern seaboard of Africa. We stopped in Madagascar, Kenya, Tanzania…we went around the Horn of Africa, dodged them pirates, up the Gulf Aden into the Suez, up the Red Sea, first into through the Suez in the Meds, across the Med, out of the Med into the Gibraltar, across the Caribbean, and ended up into the US.

GARY: Wait, I am just curious. But not counting the hours you put into the boat, did you make money when you resold Royal Salute or what?

STEPHEN: Well, we were pretty lucky. We ran a sailing school in St. Martin and taught a lot of people how to sail. And the boat was our teaching aid. So the boat almost earned as much money as she cost us to build. And then if you took the exchange rate at day, we sold her for essentially what she cost us in rent in South Africa. So that was a particularly good boat because we made the asset work for us.

ESTELLE: We found that a big problem with home-built boats is that it sometimes looked home-built and that detracts from the value of the boat. We were lucky enough, like Stephen said, we had good cabinet makers and who really did a fantastic job in our boat. And so she looked like she was built in a shipyard, professional shipyard. Also, our systems…we had a friend of ours work with us on our systems and, you know, it was near perfect by the time he were done with us.

So we had those advantages, it’s difficult to do it yourself but if you have perseverance and money you can do it.

GARY: But, don’t you think there is a hell of a lot more that goes into a boat than you anticipated?

STEPHEN: That’s an understatement. If I’d known how much we needed to do to that boat, I would have just sucked it up and paid for it and let someone else build it, you know. It was a huge amount of work, but I had a lot of help from a lot of vendors, you know. It was a fun project and it stood us in good, you know. Thereafter, for sure, as far as running our boat, we did 34,000 miles with our boat. It gave us very little trouble.

ESTELLE: Yes, I have to agree we loved the boat and if we hadn’t done it ourselves we probably would have ended up with a lot more trouble. However, unless you are absolutely devoted to this project, don’t even start it. Because it is, like Stephen says, very, very few people ever finish it and you very seldom get your money out of it once you started the project, you know. So even if you sold the hull and deck, whatever project or however far you came with the project. So be sure that’s what you want to do.

STEPHEN: Estelle was quite fine letting me start the boat because she never thought I wouldn’t finish it. She thought that would be something to keep him busy. When the day came, I said, “We are getting ready. We are going to get trucks. We are going to get all sorts of things we are to launch the boat.” She was quite shocked that, you know, this had all come to pass. But. you know, would I did it again? I don’t think I would do it again. I am not that passionate about manual labor.

GARY: Well, thank you for those valuable tips. We are going to be right back after this short break. And you are listening to “Yachts: The Perfect Escape Vehicle” only on the Overseas Radio Network. And this is Gary Fretz, Stephen Cockcroft, and Estelle Cockcroft. We will be right back.

Catamarans and Trimarans

Catamaran and Trimaran Boat Plans make it a reality to build your own catamaran or trimaran. Multi-hulled sailing vessels are a special class of boat. A very different mind set is required when thinking about sailing a multi hull, let alone getting your head around building one.

There are some unique challenges building a multi-hull sail boat, the extra beam added by each hull for instance can create storage issues while under construction. Hartley boat plans make the build process straight forward for even amateur builders. However with all things considered, building a multi can be an amazing journey.

How to Build a Boat: A Comprehensive Guide for Beginners

Building a boat from scratch can be an incredibly rewarding experience. Whether you dream of gliding across a tranquil lake in a rowboat you crafted yourself, or envision setting sail on a custom sailboat, the process of boatbuilding offers both challenges and joys. In this guide, we’ll walk you through the essential steps of how to build a boat, including material options, costs, and key considerations for designing your dream vessel.

Step 1: Decide on the Type of Boat You Want to Build

The first step in building a boat is choosing the type and design that suits your needs. Boats come in many forms, and your choice should depend on the following factors:

• Purpose : Are you building a boat for fishing, sailing, or casual recreational use? This will impact the size, materials, and overall design.
• Size : Smaller boats like kayaks or canoes are simpler and less expensive to build, while larger boats like sailboats or powerboats require more time, materials, and expertise.
• Materials : Traditional wood, fiberglass, aluminum, or even plywood? Your choice of material influences the boat’s weight, durability, and cost.

Common boat types for DIY builders include:

• Kayak or Canoe : Lightweight and ideal for calm waters.
• Rowboat : Great for leisurely lakeside outings.
• Sailboat : More complex, but perfect for ocean adventurers.
• Jon Boat : Flat-bottomed, typically used for fishing in rivers and lakes.

Cost Estimate:

• Kayak or Canoe : $300 – $1,500 depending on materials.
• Rowboat : $500 – $2,500 depending on size and construction.
• Small Sailboat : $1,500 – $7,000.
• Jon Boat : $600 – $2,000 depending on size.

Step 2: Select the Right Materials

The choice of material is one of the most important decisions in boatbuilding. Each material has its pros and cons, affecting the boat’s weight, durability, and ease of construction.

• Wood : Traditional, aesthetically pleasing, and widely available. Wood is easy to work with but requires regular maintenance to prevent rot and warping. It’s ideal for beginners building small boats like rowboats or canoes.
• Cost : $200 – $1,500 for a small boat , depending on the type of wood.
• Plywood : A more affordable option than solid wood, plywood is widely used in boat construction. Marine-grade plywood is water-resistant and durable.
• Cost : $100 – $500 for a small boat.
• Fiberglass : Lightweight, durable, and requires less maintenance than wood. However, working with fiberglass requires some skill, as well as specialized equipment. Fiberglass boats are great for larger builds.
• Cost : $1,000 – $5,000 depending on the size of the boat.
• Aluminum : Extremely durable and lightweight, aluminum is often used for fishing boats. However, it’s more expensive and requires specialized tools to cut and shape.
• Cost : $1,000 – $7,000 depending on size and specifications.

Step 3: Gather Your Tools and Plans

Before starting your boat-building project, gather all the necessary tools and materials. You’ll need:

• Saw (circular, jigsaw, or table saw)
• Drill and Bits
• Measuring Tape
• Sanding Tools
• Epoxy Resin (for fiberglass or wood boats)
• Marine Sealant or Varnish
• Copper Nails or Screws (for wood construction)

In addition to tools, you’ll need detailed boat plans . For beginners, purchasing pre-drawn boat plans can save time and effort, ensuring you follow precise measurements. Many boat plans are available online or from marine supply shops, and some are even free for smaller, simpler boat designs.

Cost Estimate for Tools and Plans:

• Tools : $200 – $600 if you don’t already own them.
• Boat Plans : $0 – $300 depending on complexity.

Step 4: Build the Hull

The hull is the main body of the boat and typically the most time-consuming part to construct. Follow these basic steps:

• Prepare the Frame : Start by constructing the boat’s frame, typically made from wood. This is like the skeleton of the boat, providing structure and support.
• Assemble the Hull : Attach the planking or panels (depending on your materials) to the frame. For wood boats, you’ll use wooden planks, while fiberglass boats require laying down fiberglass cloth and coating it with resin.
• Waterproofing : Once the hull is assembled, apply marine-grade epoxy or sealant to make it watertight. For wood, varnish or paint will protect it from moisture and the elements.
• Install Bulkheads and Seating : If your boat requires bulkheads (the internal walls that provide structural support) or seating, now’s the time to install them.

Cost Estimate for Hull Construction:

• Small Wooden Boat : $200 – $1,500.
• Fiberglass Boat : $1,000 – $4,000.

Step 5: Add the Finishing Touches

With the hull complete, it’s time to install the finishing components. These include:

• Decking : If your boat design includes a deck, install it using durable, weather-resistant wood or composite materials.
• Hardware : Attach cleats, handles, or oar locks as needed.
• Painting or Varnishing : Apply the final coats of paint, varnish, or other sealants to protect the boat from the elements and enhance its appearance.
• Sails, Motor, or Oars : Depending on the type of boat, install any sails, rigging, or motor mounts required. Rowboats and kayaks will need oars, while sailboats require a mast and rigging.

Cost Estimate for Finishing Touches:

• Decking : $100 – $1,000.
• Hardware : $50 – $300.
• Paint and Varnish : $100 – $500.
• Motor or Sails : $500 – $5,000.

Step 6: Test Your Boat

Once your boat is fully assembled, the final step is to test it in the water. Before heading out, ensure that the boat is watertight, balanced, and fully functional. You may want to test it in a small body of water or even a swimming pool before taking it out to the lake or ocean.

Overall Cost Estimate

The total cost of building a boat depends on the size, materials, and complexity of your design. Here’s a rough breakdown:

• Kayak or Canoe : $400 – $2,000.
• Rowboat : $700 – $3,000.
• Small Sailboat : $2,000 – $8,000.
• Jon Boat : $1,000 – $3,500.

Tips for First-Time Boat Builders

• Start Small : If this is your first boat-building project, start with a simple design like a rowboat or canoe. It will be more manageable and less expensive.
• Buy Pre-Cut Kits : Many companies offer pre-cut boat kits, which include all the materials and plans you need to get started. This option saves time and reduces the chances of errors.
• Join a Boat-Building Class : Community workshops or marine clubs sometimes offer boat-building courses. These can provide hands-on experience and guidance from experts.
• Watch Online Tutorials : Many seasoned boatbuilders share their techniques online through video tutorials, making it easier to learn.

Building a boat is an exciting, rewarding challenge that allows you to create a vessel perfectly tailored to your needs. While it may require time, effort, and careful planning, the end result is a one-of-a-kind boat that you can take pride in knowing you built yourself. Whether you’re crafting a simple rowboat or a more complex sailboat, this guide provides the essential steps to help you get started. With the right materials, tools, and patience, you’ll be ready to set sail on your handcrafted boat in no time!

Catamaran sailing: expert multihull techniques

• Nikki Henderson
• February 18, 2022

Moving to a performance multihull can be a leap for even the most experienced cruiser. Nikki Henderson shares expert multihull techniques.

There has been a huge surge in the sales of performance multihulls and with them a need to know how to handle them particularly when it comes to specific multihull techniques. The market for these boats is broadening; multihull cruisers are upgrading, monohull sailors are upsizing, and even virgin boat owners are tempted.

Over the last 12 months, while coaching for Outremer , I’ve met hundreds of these owners, everyone from young families to retired couples moving aboard a new catamaran and setting sail on a circumnavigation. Handling a performance catamaran is achievable even for a novice multihull sailor. But there is a big difference between just ‘getting by’ on such a boat versus sailing efficiently, safely and in style.

The transition for even experienced sailors can be quite a step up. For a seasoned monohull sailor, the differences are obvious: increased volume and speed, and a lack of heel. Even for an existing multihull sailor, the handling and performance is noticeably less forgiving and requires a shift in focus and technique.

This winter, I set sail on a transatlantic with the new owners of an Outremer 55 . They have previously owned another less performance-orientated catamaran but invited me on board to coach them to fine tune the boat, assist with routing, and help them take best advantage of all the performance their new yacht offers. Here are a few of the topics we focussed on:

sailing at higher speeds will change everything from manoeuvre techniques to weather routing. Photo: Robin Christol/Outremer

Most non-planing monohulls will do approximately the same speed on all points of sail. However, a performance multihull might sail at twice, three, even four times its upwind speed on a reach.

For example, the factory polars of an Outremer 55 give its average speed in 20 knots of wind with a true wind angle (TWA) of 50° at 8.5 knots, but in the same windspeed with a TWA of 110° it’s 19.1 knots. That’s more than twice as fast. How do you make the most of this speed advantage? And how do you best manage it ?

In a monohull it often pays to slog it out for days sailing the best course to windward as this normally gives the best velocity made good (VMG). A dead downwind rhumbline route is the usual strategy for longer ocean passages, rather than sailing more miles and wider angles.However, on a performance multihull it is important to prioritise reaching when route planning.

In upwind conditions on a long crossing, consider whether bearing off by even as much as 20° will result in a better VMG, even if it feels counterintuitive. In light winds bearing off to 70° or 80° TWA can be the difference between a totally stalled boat and 5 knots of boat speed .

Faster speeds open up the possibility of keeping up with pressure systems as they move around the globe. For example, if crossing the North Atlantic eastwards, ideally you’d leave the US in clear weather with a depression forecast to leave the American coast a few days later.

You could use its predicted track to decide how much north or south to add to your easterly heading, to ensure that as it catches up with you, you are sufficiently south enough of it to pick up its strong westerlies. As they approach, you will accelerate, and if you can hold the speed you can use that downwind airflow to push you most of the way across the pond.

Handling at speed

Controlling and handling the boat at these higher speeds requires a change in strategy. Increased speeds and acceleration mean that the apparent wind angle and apparent wind speed change much more frequently. So you need adaptable and flexible trimming and driving solutions.

Use twist to balance power and control. Photo: Robin Christol/Outremer

Downwind the boat should be carving S-curves through the water to ensure it achieves the best VMG possible. If you can get this right you will attain the momentous double figure average speeds that a performance multihull offers, while also going the right direction! Instead of allowing the speed to plummet at the end of each surf, as the bow sinks into the bottom of the wave, a performance multihull can just keep on going.

How to maintain speed:

1 Sail at higher angles to build up apparent wind speed (AWS) and boat speed.

2 Soak downwind as the apparent wind angle (AWA) surges forward with the acceleration.

3 Drive the boat back slowly upwind in time to maintain the average speed and continue the surf.

In an ideal world, to achieve this the boat would be hand-steered. But realistically, no cruisers want to be on deck for two weeks straight on a transatlantic crossing. Your best compromise is to invest in a top quality, well set up autopilot, as well as good wind instruments.

Set the autopilot to sail to apparent wind angle and watch how the boat slaloms through the ocean. The quality of the autopilot will really start to show its value when the sea state starts to increase. The best ones improve over time as they collect data and learn the wave patterns. If you aren’t sure exactly which AWA is ideal, choose a day that has very consistent wind and sail in open water. Set the autopilot AWA to 90° and then systematically increase the setting by increments of 5° at fixed time intervals until you get as low as you can before the foresail is shadowed behind the main. Measure the VMG by comparing the distance travelled at each of the different wind angles, and the average A to B course over ground (COG) achieved. This will give you a good starting point, and then it will shift further depending on sea states and wind strengths.

Sail setting

Another solution if you want fast speeds but don’t want to actively sail the boat to within an inch of its life is to use twist. Twist is a compromise between having a hardened sail that stalls when the wind goes aft, or a very eased sail that luffs when it goes forward. The more changeable the conditions, the more extreme the acceleration increases are, or the rougher the sea state is, the more twist you need.

Cats have the space and stability to hoist and douse, so keep weight low by dropping flying sails when not in use. Photo: Christophe Launay

The wide beam of a multihull allows for a long traveller, so most won’t have a vang. Sheet tension and traveller position are your primary controls to create twist in the mainsail. Begin by finding a full power setting in the main.

Set your autopilot to 35-40°AWA; most performance multis should make this upwind. Set your traveller at midships and over-ease your mainsheet so that the sail is luffing. Gradually tighten your mainsheet until the top telltale just flies. Manual winching offers better control here than electric.

Pull your traveller to windward until the boom runs down the centreline. The top telltale of the mainsail will now be flying about three-quarters of the time. If it is closer to 50% you may need to tighten the mainsheet further and then ease the traveller until you have achieved this (or vice versa). This is your full power sail shape, and your default car position upwind.

At this point some people like to mark the mainsheet (this doesn’t work with a continuous mainsheet). To begin with, just take note of the traveller position. If the conditions require more twist, ease the mainsheet, and pull the traveller to windward to keep the boom in the same position relative to the boat. You could keep a note of three traveller positions for each point of sail: full power, mid power, low power.

As the wind moves aft, you can add other ‘go-to’ traveller positions for different wind angles by easing the traveller down to leeward while keeping the mainsail shape set to ‘full-power’ mode. Once the wind goes aft of the beam, your traveller will be all the way down to leeward. Keep an eye on spreader chafe at this point.

Once you are happy with mainsail trim, you can trim the jib in a similar way, using car position and the sheet tension. Bring sheet tension in so that the leech shape looks very similar to the main: flat with a slight curve at the top. Then adjust the cars (if you can) so that the sail is not luffing, and the top telltales are also flying 50-75% of the time. Finally, walk forward to the forestay and view the slot between the sails. Do they look roughly parallel? If not, you may need to open up the slot a touch by moving the car outboard. This is your default jib car position for that point of sail.

When conditions increase, don’t forget to add twist to the jib too. Initially just ease a touch of sheet. Be careful moving the car too far inboard or you might close the slot. Moving the sheet attachment closer to the foot of the clew will open up the leech and create more twist.

Think of twist as the middle ground between sailing fully powered and reefing. Multihulls are much less communicative than monohulls. You do not have the obvious signs that the boat is overpowered, like a submersed toe rail or rounding up as the boat heels.

In time you’ll get to know your catamaran and build a connection to read how aggressively the boat is accelerating, its fore-aft pitching, sounds, and rhythm. But at first it’s useful to have some number guides and wind parameters of when to add twist and ultimately when to reef.

Generally a performance cat will require a reef much earlier because it’s lighter. I’d usually put in one reef at 20-25 knots, two at 25-30 and three reefs for 30-35 knots.

On our transatlantic crossing on the Outremer 55, contrary to my advice on the advantages of sailing angles downwind, we chose instead to sail dead downwind with the symmetric spinnaker up for the entire passage.

There are costs to taking full advantage of the speed of a performance catamaran. Averaging 15 knots boat speed is not everyone’s idea of comfortable. The hulls are so stiff that every wave that hits the hull sounds like the beating of a drum. The humming of carbon rigging, the swooshing of water screaming past the topsides, the slapping of the waves, the wind: it’s incredibly loud even when averaging 10 knots, let alone 15 or 20.

Performance multihulls are also so lightweight that they are really thrown about in a substantial sea state. Our decision to sail dead downwind rather than heating up and taking full advantage of the performance came down to the following reasons:

1. Lack of adequate autopilot We had one, but it wasn’t able to react quickly enough to the acceleration and resulting rapid change of wind angle that broad reaching would have created. It also struggled in a big seaway, so sailing with the waves square on to the stern was easier to cope with.

2. Sails We did not have a heavyweight asymmetric sail, which is what you need to sail these downwind angles (both our reaching sails were light weight).

3. Safety Akaroa II is hull No2 of a new design by Outremer. This was the first transatlantic crossing that this particular model of boat had ever done, so we were a testing ground and deliberately cautious.

Despite our conservative approach we still achieved 90% of the factory polars averaging 9.6 knots in sustained winds of 20 knots across the entire 2,700-mile route.

The trip took 11 days and 17 hours. The beauty of a performance multihull is that even if you don’t push it, you still manage brilliant speeds in the right conditions.

We calculated how much faster we would have gone, had we sailed the angles instead of running downwind. This assumes we would achieve the same 90% polars. TWA 140° appears to be the sweet spot.

Getting the main down when reefing can be problematic – rig up downhaul lines to help grind it down if needed. Photo: Nikki Henderson

Without any power being dispelled by heeling, performance multihulls will convert additional power into acceleration. With this increased speed comes increased loads on the lines, blocks, rudders, sail cloth and rigging. Winches are upsized. Jammers are used instead of clutches. Halyards are 2:1. You may be sailing on a 50-footer, but the loads are akin to a 70-80ft bluewater monohull.

A future owner recently reminded me of this, when he opened the main traveller jammer while holding the line with only one wrap on the winch. The lack of skin on his hand was gruesome evidence of how surprising the loads can be when a multihull is really powered up.

Interestingly, comparing a standard cruising multihull with a similar sized performance multihull, the opposite is true. A boat that weighs less needs less sail area to power it. For example, a Lagoon 450 has a sail area (main and jib) of 130m2 compared to an Outremer 45 (actually 48ft LOA) at 104m2. So, for the same apparent wind speed, there will be less load on the gear.

Watch out when sailing downwind. Due to a performance multihull’s ability to accelerate and hold high speeds downwind, it is easy to hold significantly more sail area in higher true wind speeds as the apparent stays low. However, if you do hit the bottom of a wave and stop dead in the water, the sail, rigging and lines will feel the full force of that wind.

Another reason to reef earlier than you think on a performance multi is that with swept back shrouds (needed to support the mast without a backstay) and a fully battened mainsail, even with the halyard eased downwind the sail may still not come down. You should be sailing with the minimum amount of sail cloth up to achieve the polars.

Reducing sail

1. Rig up downhaul lines from each reefing point on the luff to help grind down the sail. Keep an eye on chafe on the leeward side on each of the batten pockets.

2. Use the rotating mast to open the sail to the wind more.

3. If that isn’t enough, come upwind to help get the sail down.

Multihull trim

Switching to a performance catamaran may bring new trimming options: daggerboards, a rotating mast, and fully battened square topped mainsail.

Brush up on your fundamentals of sail trim so that you have a solid foundation to build on. When you first start sailing the boat, to avoid getting overwhelmed (which tends to result in people under-sailing their boat), begin by finding a base setting for all points of sail. Forget the rotating rig for now, but find enough twist in the sails that gives you enough height without too much power. Set the daggerboards as you would on a dinghy: down for upwind, up for downwind, mid-way for a reach. Then you fine tune.

When adjusting daggerboards, make sure you have your GPS track switched on. See if dropping a little more daggerboard helps with the COG upwind. Downwind, if you feel like you are on an ice-skating rink, try dropping a little board for better grip. If on autopilot, take note of the rudder angle. If it’s taking the helm from full starboard to full port then it might need some more grip, if not then a reef.

Be cautious of the risk of ‘tripping up’ in big seaways. In sea states much over 3-4m, it’s safest to lift the daggerboards and allow the boat to glide over the waves rather than risk one of the boards digging into a wave and destabilising the boat. While exceptionally unlikely to happen, if a daggerboard digs in, the worst case scenario would be a capsize. If you see any slick in the water that suggests the boat is sliding sideways over a wave, or an increase in heel, or significant water over the deck – these are signs that it’s time to lift the boards all the way up.

Finally, play with the rotating mast. At a basic level, try to get the mast in line with the foremost sail position and curve. The easiest way to see this is actually to stand forward of the mast and look down the line of the sail. It is in itself a foil and when in the right position can add the equivalent of as much as 10% more sail area. In the same way, you can use it to depower by reducing the angle.

With a rotating mast you’ll generally be trying to get it in line with the foremost sail position and curve. Photo: Nikki Henderson

When fine tuning sail trim I’d recommend marking all your tracks and angles of mast rotation, and once you are confident you could mark the sheets and halyards themselves. This is an exercise for the detail-orientated and it pays to be specific. Keep a notebook at the helm station to record your learnings, and over time build up not just ideal trim settings for wind and waves, but also polars.

Learning a performance catamaran’s sensitivity to weight can be a real learning curve. Compared to cruising catamarans, performance cats tend to be half the weight (or even less). Meanwhile, compared to a monohull the main difference is in the areas where the weight is most concentrated. A monohull’s weight is predominantly in its keel. Almost the entire weight of the boat is concentrated in around 15% of the boat’s length. Conversely, a multihull has no keel, so without that pendulum effect its centre of gravity is higher and less stable. On a multihull the weight is distributed along almost 90% of its length.

In practice, this means that what you carry, both below and above decks, has a big impact on the boat’s performance and safety. The first step is to become minimalists. Summon your inner Marie Kondo and ask yourself “Does this bring me joy? Does this keep me safe?” of every single item that moves from dock to boat. If it doesn’t – don’t take it.

Step two is to arrange your belongings evenly around the boat. Ensure you don’t list the boat to port or starboard. Try to keep weight amidships and ideally low down. Avoid loading up the bow lazarettes or aft areas with too much weight.

When sailing, don’t forget that the worst kind place for weight is aloft. Without the keel, you significantly reduce the stability of the boat by having a furled Code 0 (for example) hanging around up the rig. It’s inconvenient to drop it every time, but it’s worth it.

Higher speeds, bigger loads, a lighter boat and higher centre of gravity don’t sound like the safest characteristics, and they aren’t if poorly managed. But you can also use them to your advantage. Being able to sail faster means you sometimes have an option to run away from bad weather.

But there are other safety drills that are worth thinking about ahead of time. What is your MOB recovery plan? With cats’ high freeboard, some owners plan to reverse up to the casualty and pick them up from the steps at the back. But how many have practiced that? Will it involve dropping the mainsail? Could the props injure the casualty? How does the back of the boat behave in a significant sea state? I’d recommend practising this until you have a plan that works for you on your boat with the equipment you have. The same should be said for plans to evacuate the boat, or deal with a fire on board.

DIY Styrofoam Catamaran

Introduction: DIY Styrofoam Catamaran

This is a Styrofoam catamaran i built. I had been wanting to build this for a while, then in the last few days of summer i decided to build it. This only took 2 full days to build and one day to test. The catamaran costed me around 200 dollars (sail not included) and this is comparable to a store bought catamaran which would cost 2000 dollars

In this instructable i have included a few schematics (located on the last page) , a materials list, and various pictures and descriptions for all steps.

If you plan to build this project i suggest you check out the video and if you like this project be sure to check out my channel or my website for more projects like this.

Step 1: Materials

The materials i needed for this project were:

2"x4"x8' pieces of wood - 2

2"x3"x8' pieces of wood - 1

2"x2"x8'pieces of wood - 6

1”x2’x8’ Styrofoam sheet - 5

1.5”x14”x4’ Styrofoam sheet - 5

½’’x2’x4’ piece of plywood - 2

½’’x4’x6’ piece of plywood - 1

Sail and mast - 1

Epoxy (dollar store epoxy is cheapest and works well) - 7

Step 2: Assembling a Pontoon

The catamaran will be composed of 2 pontoons. These pontoons will have a frame filled with the white, less durable Styrofoam in the center; then we will later add the pink Styrofoam to the outside.

To start off i lay out two 2x2 pieces of wood with the white Styrofoam pieces in the center. This will be the inside of the pontoon. Next i add a front triangle onto the pontoon. As you can see in the third picture i added 2 struts near either end of the pontoon. Once that is finished i fill the pontoon with white Styrofoam and cut it to fit in the gaps.

Step 3: Finishing the Pontoon

to finish off the pontoons we must first cut 4 pieces of Styrofoam to size (2 for each pontoon). To cut them all at once i clam them together and use a reciprocating saw to cut the height from 2 feet to 17 inches (the height of the pontoon).

After that i use 1 - 1.5 tubes of epoxy as adhesive. I spread the epoxy on the wooden frame and then lay the Styrofoam down onto the wooden frame and add weight to it so the Styrofoam stays tight to the frame as the epoxy hardens. After that i use the saw to taper the bottom edge. I also add Styrofoam to the front triangle and taper that as well. Once complete you should go ahead and do that for both pontoons.

Note: The strut layout in the second pic is different then the layout of the of the struts in the previous page. The layout in the previous page showed the correct positioning of the struts.

Step 4: Completing the Pontoons

Now you can see both pontoons side by side. To complete them i add a wooden triangle positioned at the top, and lined up with each strut, this will be used for mounting the frame. To add some more buoyancy i also cut a full 2' x 8' piece of Styrofoam in half lengthwise (giving us two 1' x 8' pieces). I use epoxy to mount those onto the inside of the pontoons.

Now both pontoons combined give a buoyancy of 460 lbs when fully submerged. This seems like a lot but when you consider you wouldn't want more then 60 percent of the pontoon submerged (then you would be uncomfortably close to the water) and you might also have you weight towards one side of the pontoon then it seems this 460 lbs is just enough for one person to float comfortably. (i fit 2 full size people on but it sits very low). If you wish to be able to make this a 2 person boat you can add more Styrofoam sheets to the outside. Each 1"x 2' x 8' sheet once cut to a height of 17" provides 62 lbs of buoyancy when fully submerged.

These calculations are fairly simple to do on your own. First calculate the volume of the object (length in meters x width in meters x height in meters), this will give you volume in meters cubed. Then multiply the value you get by the density of water (1000 kg/m cubed) this will give you how many KG the object can float when fully submerged.

Step 5: Making the Frame

To make the frame i cut my 2x4 s to 4.75 feet long and attached them to the pontoons using screws. I chose that width because it was just small enough that i would be able to fit the frame (when separated from pontoons) in the back of my van. Next i add the 2x3 piece down the middle of the boat. This is both for structure and to mount other parts off of.

Step 6: Adding the Keel

Now i cut out the keel out of a piece of plywood. Using the plywood, i also glue a slot so that the keel can be slid in and will be able to slide up and down within the slot.

The keel is an essential part of the sailboat and helps to turn the force provided by the wind into thrust in the forward direction. This is also the pivot point when you turn your boat

Step 7: Adding the Rudder

The rudder will need to rotate so i decide to mount it off of a hinge. I add a hinge to the back of the boat and then cut the rudder out of the piece of plywood. The rudder should be fastened in place with 2 bolts and the bolts should have a washer in between the nut and the wood of the rudder. The bottom bolt will have to be taken while the boat is out of the water so that the rudder can pivot upwards when it is on dry land.

To finish off i add a handle made of plywood. The handle is to only have one bolt through it so that it can pivot up and down.

Step 8: Finishing Touches

To finish up i cut a piece of plywood to size and fit it on top of the catamaran to use as a seat.

After that we need to make somewhere to mount the mast of the sail. To do this i obtain a small piece of pvc pipe and heat the bottom of it so i can squeeze it down and make it thin. Once that is done i simply mount a few screws in it to attach it to the frame of the boat.

Step 9: Setting Up the Sail

Now i use a mast and sail that i had laying around and slide it into the pvc pipe. I secure the mast with metal cables that attach to various points on the boat. Once the mast is in place i rig up the main sail and the jib and it is now ready to sail

Step 10: Testing Out the Boat

Now that the boat is complete you can go ahead and take it out on the water and test it out. Be sure to wear a lifejacket and bring a paddle just in case you have a hard time getting it in using the wind.

To see the test you can also check out the video

Step 11: Schematics

Here are a few schematics of the boat, they are not to scale. Beside the schematic picture i also attached a real picture of the boat

In order we have a top view of the boat, a front view, a side view, and a picture of the rudder and keel. All measurements of the schematics are done in meters.
