A brand-new cruising catamaran can set you back a hefty amount of money. However, a DIY cruising catamaran provides a more affordable way to own your own boat. While building a large boat can be an extremely challenging and time-consuming experience, nothing beats the pleasure of bringing your own boat to life.
To build a DIY cruising catamaran, buy good design plans, determine your budget and find a working space. Next, choose your hull material, buy supplies and start building the mast beam. Build and sheathe the hull, install bulkheads, the interior, and finally, launch the catamaran boat.
In this article, you will find a complete guide to building your own catamaran. You will also find detailed information on why you may want to consider building your catamaran and approximately how much this project would cost. Finally, we will explore the advantages and disadvantages of building a catamaran from scratch.
Why You Might Want To Build Your Own Catamaran
Most people might think that purchasing a used boat to repair and fix it up would be cheaper than a DIY cruising catamaran. But while building your own catamaran could be an enormous undertaking, it also comes with many advantages over buying something used.
Other than the unique opportunity to create beautiful memories and experiences while cruising, sailing, and exploring beautiful coastlines, there are a number of benefits that come along with the DIY approach.
Knowing Your Boat
Building your own catamaran provides you with intimate knowledge of your boat. You will know every corner, including where to find every bolt, wire, bulkhead, rib, hose, and support as you installed them yourself. This knowledge will enhance your confidence while at sea since you will have entrusted your life to a boat whose history you are aware of and deeply connected to.
Pride of Ownership
The satisfaction you get from crafting something with your own hands is immense. As a result, the knowledge that you built your boat from scratch will fill you with absolute pride and an immense sense of achievement. Furthermore, as an owner-builder, you get to keep and enjoy the boat for as many years as you wish.
Substantial Cost Savings
Building your catamaran will work out cheaper than buying a new or even gently used boat. Though you will likely require some additional labor since doing some things will require an extra pair of hands, if you are particularly good at DIY, you will save a significant amount of money on labor costs as a whole.
Freedom To Create Your Own Designs
If you decide to buy a catamaran boat, it might not be easy to find one that meets your unique needs. However, instead of choosing from production boats that bear traditional and outdated designs, you can come up with an ultra-modern design or style for your catamaran. You also get to pick your layout, size, and equipment based on your taste and budget.
Great Learning Experience
Building your own boat will help you pick up numerous skills that will come in handy later when sailing your boat. As much as you might still require an expert to help you with specialized skills like carpentry or wiring, your new skills will serve you well. This will also be beneficial when it comes to your boat’s maintenance and fixing things for yourself.
What To Look For in Catamaran Boat Designs
When deciding on the type of catamaran boat to build, you may want to choose a design that’s simple and easy to build. This is because doing so will allow you to spend a shorter time building the boat.
You also need to have a set of requirements to guide you in choosing your design or what you might call an ideal cruising catamaran wish list. This is essential because, ultimately, you want to build a boat that offers outstanding qualities such as:
- Delivers good speed
- Affordable to own and operate
- Agile, strong, and easy to maintain
- Has a high resistance to capsizing
- Great for sailing and cruising
- Delivers a comfortable and easy motion underway
- Good handling ability and high performance under sail
- User-friendly embarking and disembarking
- Provides ample living and accommodation space
- Presents a reasonable resale value
It’s worth noting that, in general, catamaran boats tend to offer a fair resale value mainly because of scarcity and the high price accorded to production models. So, if you build a well-constructed catamaran, you are bound to get a return that’s much higher than the cost of materials upon resale.
It’s also good to consider whether the design you settle on is from an established designer. This is significant because documentation of the building process is just as valuable when it comes to selling the boat.
How Much Would It Cost To Build Your Own Catamaran?
The cost of building your cruising catamaran will depend heavily on the size of the boat you plan to build and the skills you bring to the table. To give you an idea of probable costs, a professionally built 40 foot (12.1 m) long cruising catamaran could go for up to $300,000.
Though building it yourself will undoubtedly be cheaper, most DIY boatbuilders tend to underestimate the expected costs. Your final costs should cover not only the cost of material and equipment but also the labor and time it would take to come up with the final product.
If you were to build a 40-foot (12.1-meter) catamaran, your cost of materials would range between 20-30% of the total cost. Therefore, for $300,000 total, the boat’s materials would range between $60,000 and $90,000. The hull tends to range between 15-35% of the total build. Again, this depends on the finish and furniture.
But before you even start working on the DIY project, you will need to figure out where to do the work. If your home has ample space, then you can opt for a backyard building. But if you live in a small apartment, then you might want to consider renting a small garage at first and then move on to a boatyard later. This is one of the significant costs involved in building your multi-haul.
What You Will Need
To get a clearer picture of how much the entire project would cost, let’s have a look at what else you will need to purchase.
- Good design plans
- Working space
- Ground tackle
- Matting and roving
- Equipment such as the engine, windows, rudders, deck fittings, mast, and rigging
In addition to the above, you also need to install plumbing and electricals. You may also want to consider going electric rather than using diesel. Not only will this drastically reduce your maintenance costs, but you get to use the regenerated power for all of your housing needs while sailing.
Some catamaran boat designs help you save costs by advocating the use of less expensive corpus materials. Most of the material goes directly into making the boat, which means there is hardly any wastage on vacuum bagging . With this method, there are few molds and temporal building forms and fewer fillers to grind off as waste. All these factors reduce the time and cost it takes to build your catamaran boat.
That said, building a boat of any kind is a huge financial undertaking. As such, you still need to have the financial ability to keep building; otherwise, your project will stall or take much longer than anticipated. Instead of enjoying yourself and making memories cruising to faraway lands, you might end up spending all your time building a seemingly never-ending boat.
To reiterate, this project is more of a labor of love, given that it involves a tremendous amount of manual work. Calculating an hourly rate on the time spent building the boat and adding this cost to that of materials may make it seem a very pricey exercise. However, it is vital to understand that your time matters, and every hour you spend working for “free” should be included.
With that in mind, you need to ensure that you are fully devoted to the boat construction project and are sure you want to do it before you begin. Stopping halfway because it seems like too much work would be incredibly costly.
How To Build a Catamaran
When it comes to building a cruising catamaran, you have 3 main options:
- You can buy an old boat and refurbish it.
- Purchase a bare hull plus deck molding for a home-boat building.
- Start from scratch and build everything, including the hull, on your own.
As mentioned above, renovating an existing boat may end up being more costly than starting from scratch. To build a catamaran boat from scratch, follow the below step-by-step guide.
Prepare the Essentials
Before you jump into such a large project, there are several important aspects to consider:
- Buy your plans from an established catamaran designer. You can also get inexpensive, easy-to-build catamaran designs online.
- Get access to a large working space or build a shed . Depending on your climate, you may need to opt for climate control to avoid an excess of moisture in humid areas.
- Decide on your choice of hull material. This could be fiberglass, aluminum, steel, wood, or ferroconcrete.
- Start working on a bill of materials estimate. Include everything that you think you need to get a better idea of the initial costs.
Build the Mast Beam
Using wood and epoxy, cut and glue together the pieces of wood that will form the mast beam. Most of the work at this stage can occur in a garage since it involves building small parts. Still, the work could take up to 4 months, so be prepared to put in long hours.
Build the Boat Hull
Now, it’s time to build the boat’s hull. A catamaran comprises two hulls which are connected with a deck. Below is a short video showing how to build a hull mold:
This work requires a larger facility, so you might need to move out of the garage and into a boatyard. If you don’t have access to a larger workshop, consider building a shed where you can work as you do the construction. Make sure there’s enough room to fit the boat and also allow you to work comfortably. To cover the shed, you can use opaque white tarps.
Sheathe the Hull
Get all the materials you require for this stage in the construction, such as lots of resin, fiberglass, and foam for use in the hull cores. You’ll also require matting and glass roving to sheath the hull .
Sheathing helps to make the hull impervious to water and other marine borers. But first, you need to prepare the hull using a rotary sander. To make it as smooth as possible, use light, sweeping strokes. This is a very dusty task so be prepared to wear a facemask and safety goggles.
Install the Bulkheads
Next is installing the plywood bulkheads . You might need to call in friends to help turn the hulls or use a crane. In this step, you will need to laminate the hull sides on the molded hull panels and bond them above the bulkheads. Ensure the bulkheads are snug and sealed in place.
Construct the Interior Structure
Over the next couple of months, the boat work will involve joining the hulls together with the beams that you had made back in the garage. Then, install the cuddy cabin, decks , and the cockpit . Soon the boat will start to take the shape of a catamaran.
Next, proceed to construct the major structural components such as stairs, hatches, mini-keels, and the interior. Then comes the work of fairing the boat, which is quite labor-intensive.
Finally, it’s time to apply primer on the catamaran boat and start the paintwork. Before painting the boat, you will need to do additional sanding to finish off the two layers of primer as well as fill all the pinholes. Since it’s a large boat, the catamaran has lots of surface area; thus, the sanding could get extremely exhausting—mentally and physically—at this point.
The painting can take a while, too. The hulls are the easiest to paint, but the topsides, non-skid, as well as masking and prepping could seem never-ending.
The final stretch involves working on the center bridge deck cabin and other final touches like installing the engines, electricals, and plumbing. This is also the time to fix the rudders, rigging, mast, windows, and deck fittings.
Launch Your Cruising Catamaran
After many months or years of hard work, your cruising catamaran is finally ready to test the waters. After lowering the boat into the water, check carefully in case there are leaks. If none, you can set up the sails and take your catamaran out for your first cruise.
Below is a short video that takes you through the entire boat-building process:
If you don’t have deep pockets, don’t despair. It’s also possible to build an inexpensive catamaran boat, as shown in this post from the coastal passage .
The Pros of Building a Catamaran
Though it will be a costly endeavor, there are so many things to look forward to should you decide to build your own catamaran:
- It can be lots of fun.
- You get to have a new boat.
- It’s an excellent hobby for DIY enthusiasts.
- The effort is rewarding.
- It offers a great learning experience.
- You get the exact kind of boat you want.
- You can alter building plans and tailor the boat to suit your specific needs.
- It might be cheaper than buying a new boat.
The Cons of Building a Catamaran
Though there are a number of positive aspects to a DIY build, it is just as important to keep in mind that it won’t always be easy:
- Maintenance costs can be quite high.
- It’s both mentally and physically exhausting.
- It might require some technical know-how.
- It can take many months or even years to complete.
- It requires a lot of commitment to finish the DIY project.
- It might be challenging as well as expensive to get insurance.
- You will spend almost all your free time building the boat.
DIY Cruising Catamaran Tips and Tricks
If you are new to boat building, it would be a good idea to build a small boat first. This would give you a good indication as to whether you’d enjoy tackling a more extensive project like building a catamaran. Again, if you are the handy type, fixing your own electronics could also save you a significant amount of money.
Here are more tips and tricks to get the most out of your DIY cruising catamaran:
- Lower your costs. Bring down your costs even further by sourcing for parts and supplies at marine surplus outlets, Craigslist, eBay, or wholesale suppliers.
- Enhance your resale value. Most home-built boats are not easy to sell since they tend to be too customized. To enhance your resale value, it’s advisable to work with a standard design from a well-established naval architect.
- Follow the design instructions. Make sure to follow the designer’s instructions regarding the type of materials and tools to use during the build to avoid making costly mistakes.
- Maintain your original budget. Avoid any additional customizations once you have started building the boat. Using good plans and sticking to them ensures that your budget doesn’t spiral out of control.
Final Thoughts
Building a catamaran is about more than saving money. It’s fun, exciting, fulfilling, and can be a great learning experience. While it might take many months of back-breaking work, comparative shopping and sourcing for materials will help you save a lot of money. Still, at the end of it all, you’ll have a beautiful catamaran boat, all ready for your first cruising adventure.
However, if you have neither the time nor the energy to build your own catamaran from scratch, refurbishing an existing hull might prove faster and easier. It also works out much cheaper than buying a new boat.

One thought on “ DIY Cruising Catamaran: Complete Building Guide ”
Hello, I am a French Quebecer who is original, imaginative, creative and who finds that all boats and catamarans have a huge flaw and a very big lack of logic. I would have a brand new concept…. I am sending this message to any catamaran creator – designer to make those who have the opportunity and the intelligence to want to know about my innovative idea which will finally upset the market much richer. An idea that will totally change the concept of sailing, navigation and save so much worry!! All I would ask for is a small percentage of each sale of the new product. To be able to make me produce one when I have enough!! It is certain that like that, you just want to tell me: come on Mr. Lessard give us your idea but do not take your word to help me in return! But, if you are the kind of man to have only one word and maybe have a proof of your good faith if the realization of the project would make it… I will be very happy!! Giving it to everyone wouldn’t bother me either…. all I would like is to be able to find flax fiber (too expensive carbon) to be able to try to make my catamaran myself. Because not rich! Have a nice day and looking forward to having a message!!

What do I actually receive?
DUFLEX PRE-LAMINATED PANELS
DuFlex pre-laminated panels are the main and most important material used in our kits, predominantly in the flat panel designs, however they are used in Strip-planked designs also, though to a lesser extent. These panels are 2400mm x 1200mm and are CNC routed to speed up build time on our Wildernes X Series, as well as some of our power designs. For internal furniture, a paper honeycomb core is used instead of the end-grain balsa wood core that is used for main structural areas. The use of this is purely to save weight in the shell and therefore produce a faster, more responsive catamaran.

The kit process, building your own boat can be a daunting prospect, however to demonstrate each step in the kit assembly process, we've created this guide for you to study. as you can see our kits are the ultimate in building efficiency and have been streamlined over 30+ years to ensure that you're on the water faster and with less effort., how does it all go together.
The first step to building your dream catamaran begins with a strongback – this is a square frame used to position the temporary frames that will be used to form the hull shape. This frame will be set up and must be square and accurate, a string or laser level can be used to achieve this.
The forebeam is now installed along with the striker attachment fitting, as shown above. The bridgedeck is installed shortly after and taped onto the bulkheads with webs installed, this now completes what is a quite stiff and strong platform to work on.
Now that the bridgedeck is in place, the forward webs and dash will be fitted. At this stage, all furniture and internal work begins, with the main panels left off for ease of access when working.
Material Choices
Schionning material choices, solutions that work best for catamarans & why, our designs are based on cored composite construction techniques using west system epoxy resin and knitted fabrics. but given the range of today's composite technologies, which solution works best for catamarans and why written by jeff schionning, selecting the correct materials, resin choices.
It also fully protects the boat against water absorption and it can not develop the dreaded Osmosis.
We choose ATL Composite’s resin systems for their superior quality, reliability and value for money.
Having worked closely with the ATL Composites team and their products for many years, we know we can stand by their material solutions, and rely on great service should something unexpected happen.
This may not seem important but when working with a material for an extended period of time, the small things make all the difference.
CORES Which One to Use?
- End-Grain Balsa – 150kg per cubic metre
- Superlight Balsa – 94kg per cubic metre
- Western Red Cedar – 360-380kg per cubic metre
- Foam – 80kg per cubic metre
BALSA END GRAIN (150 kg/cubic metre)
Balsa has very good values and we can produce a shell using a very light laminate. It will be very stiff and very resilient to fatigue.
It has exceptional qualities including very high compression strength, extremely good sheer capabilities and fantastic sheer stiffness.
Compressive strength is the resistance to collapsing when pressure is applied perpendicular to the surface as when pushing directly onto the material with the point of your finger. Balsa is far stronger than Foam (80kg/cubic metre) in compression.
Balsa is also very strong in shear. This is when the core sample is held flat between your hands, one hand slid one way and the other slid the opposite way, when the core tears through the middle the core has failed in sheer. The amount of stretch you feel before the core shears is shear stiffness. To compensate for sheer weakness the core is made thicker. So 13mm Balsa may be equal in sheer to 19mm Foam.
(80 to 200 kg/m³)
There are many boats sailing that are built from foam as it’s mechanical properties are good for boat building.
- Initially one would expect this cat shell to be lighter as it is ½ the weight of Balsa. We do have to compensate for its weaknesses and will then add to the reinforcement the reinforcement on the outside to spread that compression load over more core and need a triaxial type weave to compensate for the veneer content that runs fore and aft on the Durakore.
- Secondly, we need to increase the Core thickness to compensate for the shear value, usually neutralizing the weight advantage.
- We only use structural foam core that is closed-cell and cross-linked.
The end result using foam core amounts to a very similar total boat weight. Professional builders can achieve a good result but usually use vacuum bagging and very good molds to achieve this.
Secondary Issues
Balsa can absorb water. It needs extreme neglect to rot (very unusual). Water soaks along the end grain quickly. It travels very slowly across the grain. We use balsa under the waterline especially because of it’s high compression strength for beaching etc. any core type must be sealed. Damage to all cores results in the same sort of repair. Notice a damp spot remaining when drying out to anti-foul… simply grind back the surface glass exposing the core, dry it out and re-glass – it’s that easy.
Timber cores are cheaper than Foam in most cases.
A light, high tech cat returns a far better (often 2 – 3 times) re-sale than lower tech materials. Often saving $10,000 on materials initially, loses $200,000 on re-sale – a serious reality.
Our boats can be built using Balsa, Foam or Western Red Cedar. Combine strength, stiffness, lightness and cost, with ease of use – it just makes good sense!

Table of Contents
Short Answer
Building a catamaran boat requires a lot of patience and skill.
The first step is to choose the right materials for the hull, such as fiberglass, wood or aluminum.
Then, you will need to build the frame of the boat, which includes the crossbeams and the main hull.
After that, you will need to install the decking, the rigging, and other components.
Finally, you will need to paint and varnish the boat, as well as install the outboard motor and other accessories.
Design & Size Considerations
When it comes to building a catamaran boat from scratch, the first step is to determine the design and size of the boat.
This should take into account the intended use of the boat, such as sailing, fishing, or leisurely cruising.
The size of the boat will depend on the number of passengers and the type of activities the boat will be used for.
For instance, a larger boat may be needed if passengers will be standing or participating in watersports.
The design of the boat is also important and should be chosen based on the intended use.
If you are looking to build a sailboat, you will need a design that is optimized for sailing.
On the other hand, if you are looking to build a fishing boat, you will need a design that is optimized for fishing.
There are a wide variety of boat designs available, so it is important to research and choose the one that best suits your needs.
In addition to the design and size, you will also need to consider the materials used for construction.
The most common materials for building a catamaran boat are wood, fiberglass, and epoxy.
Each material has its own advantages and disadvantages, so it is important to research them and determine which one is best for your project.
Finally, you will need to consider the cost of the project.
Building a catamaran boat from scratch can be a costly endeavor, so it is important to have a budget in mind before you begin.
The cost will depend on the type of materials used and the complexity of the design.
It is also important to factor in the cost of any tools that may be needed for the project.
By taking into account the design and size, materials, and cost of the project, you can be sure to build a catamaran boat that meets your needs and budget.
With the right amount of patience and attention to detail, you can build your own catamaran boat in no time.
Gathering Materials
Gathering the materials needed to build a catamaran boat from scratch can be a daunting task, but it is essential for creating a sturdy and safe vessel.
Before starting the building process, it is important to have an accurate and detailed plan for the boats design and size.
Once a plan is in place, it is time to begin sourcing the necessary materials.
The most common materials used to construct a catamaran boat are wood, fiberglass, and epoxy.
When choosing wood, it is best to select a species of timber that is strong and durable, such as mahogany, teak, or cedar.
Additionally, the wood should be clear and free of knots, splits, and other defects.
Fiberglass is a lightweight fabric that is resistant to water and provides additional strength to the boats hull.
Epoxy is a waterproof adhesive that is used to seal the boat and ensure that it is watertight.
It is important to ensure that the materials are of high quality, as this will help to ensure the boats longevity.
Additionally, it is important to purchase the necessary materials in the correct amount and size.
Too little or too much of a material can be a costly and time-consuming mistake.
Finally, it is important to keep any leftover materials for future repairs or modifications.
With the right materials gathered, the next step is to cut the wood and begin the assembly process.
Cutting & Assembly
Cutting and assembly are the most important steps when it comes to building a catamaran boat from scratch.
The first step is to decide the design and size of the boat.
This will determine the type of materials you need to gather and the amount of effort that needs to be put into the project.
After deciding on the design and size, you will need to cut the wood to fit the design.
This includes cutting the wood to the desired size, as well as cutting any additional pieces that may be needed to complete the design.
It is important to ensure that all the pieces fit together correctly and securely, as any mistakes could lead to a weak boat.
Once the wood has been cut, it is time to assemble the pieces together.
This involves attaching the pieces together with glue, screws, and nails, and ensuring that the pieces fit together securely.
It is important to be careful and patient when assembling the pieces, as any mistakes could result in a weak and unstable boat.
Once the frame is ready, it is time to lay the fiberglass, and apply the epoxy to seal the boat.
This is an important step, as it will make sure that the boat is waterproof and durable.
Finally, you can add the finishing touches, such as the hardware, paint, and rigging.
With the right amount of patience and attention to detail, you can have your own custom catamaran boat in no time.
Laying Fiberglass & Applying Epoxy
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.
Hardware: Before adding the hardware, it is important to ensure that the frame is stable and secure.
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.

Self build boats.
A philosophic attitude behind the Wharram designs is that 'urban man' can, with a little financial saving and some handcraft work, create an object of beauty. This object of beauty can then, for a period of hours, days, weeks or months, carry him/her out of the urban world into a natural never-never land; the seas and oceans; to a time when the world was young; when Mankind was directly and intimately interacting with the beauty and power of nature. There are hundreds/thousands of Wharram builders or, as I prefer to call them, "Sea People", who have done or are now doing that!" - James Wharram
A well built Wharram design is a 'Functional Kinetic Sculpture'" - Hanneke Boon
Everything you need to build your own sea-going catamaran: 3 steps
- Familiarise yourself with our range of designs and their unique qualities. For more detailed information read the Wharram Design Book which reviews each self-build boat model and offers a detailed introduction and understanding of the world of self-build catamarans.
- Order one or more sets of our Study Plans and immerse yourself into the boat builder's mindset; evaluate the costs; the amount of time required to build your boat; where you will build it and where you will eventually launch it.
- Once you have decided on the boat that is right for you to build, order the Boat Building Plans and become a member of the global family of Wharram builders and sailors. You can build a Wharram with very little experience . All Wharram building plans are drawn for the first time builder, so anyone with a modicum of practical ability can build one of our designs. Our Building Plans present quality instruction, guidance and advice for both novice and professional alike. They are all based on decades of actual building experience and thousands of ocean miles sailed, so you can be confident in your boat's capabilities and safety.
Tiki Designs
Coastal Trekkers To Long Term Live Aboards
From the car trailable Tiki 21 - winner of the 1982 Cruising World Design Competition, to the Tiki 46, a spacious ocean cruiser or charter boat, the TIKI range offers car trailable coastal trekkers to long term live aboards . Although a Tiki 21, a very popular coastal trek design, has circumnavigated, we would not recommend this for everyone! A number of Tiki 26s have also made ocean crossings, but again this is only for the experienced sailor. The larger TIKI designs of 30ft and over are craft capable of longer voyages and ocean crossings. They are designed to be less costly to build by using appropriate wood/epoxy technology and by eliminating, wherever possible, expensive metal fittings common to modern yacht design.
On the larger TIKIs the 'Deckpod' offers sheltered steering and the 'Stern Ramp' provides easy access to and from the water. The TIKIs are boats you can work and live on. The Wharram approach goes beyond simple boat design - the concept of 'Flexispace' puts emphasis on not just the physical living area, but also the 'mind space' of those on board.
Hitia Designs
Affordable Weekend Adventure Boats
The Hitia Designs are the perfect beach catamarans . They are 'coastal trekkers' and cater for those who do not want a craft for long distance or "blue water" sailing, but would like to be able to trail their boat to varied interesting coasts and lakes. Their easy economical construction, stability and speed makes for affordable weekend adventure boats . The Hitia 14 can be carried on the roof of your car and fits on the deck of a larger boat. The Hitia 17 has more stowage space and room for a tent on deck for longer excursions. These boats are ideal for small adventures and coastal treks.
Introducing: the Mana 24 'Cat Kit'
Boat In A Box
The MANA kit is sold with all the plywood cut out by CNC cutter and pre-coated with epoxy, so building the boat at home will be a bit like assembling a flat-pack . All the parts slot together perfectly so a hull can take shape in a day. Building from such a kit takes away the worry of measuring and cutting all the boat parts , which can be quite daunting to many first time builders and saves a lot of time in the early stages of building. In designing the MANA, we looked sideways into the world of camping and have combined the innovative CNC cut "flat pack" boat-building concept with the philosophy of outdoor living to create the unique MANA camper-sailer, specifically designed for trailer sailing.
The ply parts will have a first smooth coat of epoxy already applied, cutting down time in coating and sanding, so within a short time you will be able to assemble the hulls and see the boat you are building. As she is built from a pre-cut kit, we have been able to give the Mana more complex and beautiful shaping, giving her more interior volume than the Tiki designs.
Pahi Designs
The More Evocatively 'Female' Of The Wharram Designs
From the Coastal Trekking Pahi 26 to the impressive 63' flagship of the Wharram fleet 'Spirit of Gaia' - the PAHI shape is more evocatively 'Female' than the Classic Wharram designs. They are a different visual/sculptural approach to the basic design elements inherent in the Classic Designs. Constructively, they are simpler to build, using epoxy fillets instead of more difficult wood joints . They are designed to use quick growing softwood plys, coated and glassed with epoxy to achieve a durable finish. The PAHI designs were the first to use rope lashings to attach the crossbeams, giving a shock absorbing effect, without the need for metal fittings. 'Pahi' in Polynesian dialects means 'ship'.
The Pahi 42 'Captain Cook' design set fresh ocean cruising standards when she was designed in 1979. The Pahi 63 was designed in 1986 and launched in 1992 to become the new ocean going flagship for the Wharram family. During the construction of 'Spirit of Gaia' many unique new solutions to plywood and epoxy building methods were developed, which were later incorporated in the larger TIKI and ISLANDER designs.
Ethnic Designs
Traditional Pacific Sailing Craft
The Ethnic designs have been a new development at James Wharram Designs since James and Hanneke sailed extensively in the Pacific. With everything self-made these boats are lower cost to build . They cater for those who want a "traditional" Pacific sailing craft, built using appropriate modern materials and methods, but without trying to Westernise them. These designs arose after requests from Pacific Island peoples for James to design craft to overcome shortages of "traditional" building materials, but which closely reflect the cultural and ethnic origins of these craft.
Classic Designs
The Early Wharrams - Sturdy and Stable
The early 'Wharrams', now known as the Classic Designs, are recognised as beautiful, safe boats - easy to build, and easy to sail . Many anchorages around the world are graced by these Classic Designs, and of the seventeen drawn between 1957 and 1976, nine are still available, from the 16ft Maui to the 51ft Tehini. They were the first range of Wharram catamarans, designed in the 1960s and 70s, based on the sea experience of James Wharram's pioneering ocean crossings. They are sturdy, very stable, but relatively basic in design. They are built using simple plywood construction over a backbone and bulkhead frame .

Check out the " Pilothouse Online " article about Buster. Please see the Plans List Page for a summary of Plan prices. Larger and smaller preliminary motor yacht designs can be found on our Prototypes web page. 'Dream' Yachts - A Distinctive Style These are my own favorite kind of motor yachts - designed for simplicity, economy, and style...! I call them 'dream-yachts' after their inspiration, the classic 'Dream Boats' of the 20's and 30's that plied the waters from Seattle to Juneau, Alaska. Seaworthy, yet very easily driven. Renegade 50 - Renegade is very nearly the same as the 49' Quinn, and in my view equally ideal... Same layout, with just a bit more headroom, more displacement, slightly greater beam for a bit of extra room inside, and subtly different profile... All other features are identical to the Quinn 49. Hull construction optimized for steel, therefore also aluminum. Wood or fiberglass equally possible. See the Plans List Page for a summary of Plan prices. Quinn 49 - Another member of the Moxie / Renegade family, Quinn is my own ideal type of motor yacht for simple, efficient coastwise cruising. As with Moxie, a classic gracefulness prevails. The covered aft deck is large enough for outdoor living, and the interior has all the amenities required for a couple who wish to live aboard for extended periods. As with Greatheart 48, the intent was to get the largest boat still able to be driven by the commonly available 4 cylinder marine diesels. Hull structure optimized for aluminum. Steel, wood or fiberglass also possible. See the Plans List Page for a summary of Plan prices. Moxie 43 - As seen above, Moxie is a classic motor yacht.

Please see the Plans List Page for a summary of Plan prices. Larger and smaller preliminary 'tug-yacht' designs can be found on our Prototypes web page. Multi-hull Power Yachts A multi-hull is usually given a light and slender hull form in order to gain efficiency to operate on less power and use less fuel. If designed for high speed they must still be light, and must be given considerably more power... Twee Schoenen 35 (Power Cat) - A tunnel hull aluminum power catamaran, intended as a live-aboard cruiser. Sufficient fuel is provided for long passages at reduced speed. Please see the Plans List Page for a summary of Plan prices. 60' Power Trimaran - Aluminum, plywood or GRP... any of those materials would be suited to this power trimaran. A highly interesting design study having great potential. The original request was for a power tri with "traditional" styling. This is so-far just a concept design which was done to illustrate a vessel type that has considerable merit for long range cruising. Efficient passagemaking in spades... Preliminary design information & Study Drawing available; please inquire . Larger and smaller preliminary multi-hull designs can be found on our Prototypes web page. Yacht Tenders This series of Pram designs offers the ideal companion to any of our yacht designs...! Why not...? The Pram - The pram hull form has the most carrying ability within the least length.
