The Fusion 40 "Kit Cat" is revolutionising the boatbuilding industry. This vessel has been designed from the beginning as a high performance cruising catamaran that can be stacked into 40 foot containers and freighted anywhere in the world.

This photograph shows the infusion moulded components as they would appear when removed from the container. Complete with moulded non skid and all the recesses for hatches and portlights. The components even have individual quality control certificates.

Construction Flexibilty:

By producing this modern catamaran in modules, which in turn fit in containers, it has meant delivery is simple and it has opened the doors to worldwide marketing of the Fusion 40. The cost savings on overseas shipping as deck cargo, is in excess of $40,000.00. Private contractors are available to assist with assemblies to any stage if you desire.

By producing a catamaran in sections also has great appeal to the professional boatbuilder as well as amateurs, as they can install mechanical and furniture items as they assemble, rather than working in confined spaces.
No longer are you dictated to, Fusion Catamaran Co. supplies the structural components along with the hull and deck sections but leaves the entire fitout and layout to the owner. This allows the builder to work with their preferred materials, and allows for personal preferences as to accommodation and functions. However Fusion Catamarans have a very comprehensive Multihull Construction Guide web site to support clients.
By producing the supplied components in Foam/Glass, they are weather proof and even if your build project ran into years, there will be no deterioration, shrinkage, dry rot, etc., of the components
Instead of spending 6 months gluing strips and planks, then glassing over and fairing, fairing, fairing only to finish up with a product that has small appeal to another buyer, you can now have a beautifully gelcoated, factory finish on your Catamaran, which can be assembled in as little as 12 days (4 men).
Having gelcoated, fibreglass, foam cored and production built components (to Class "A" CE Certification) provides comfort to the owners that his vessel will be highly sought after when it comes time to sell.
Also by having a worldwide marketing base through the Agent/Builder network, an owner can gain comfort in the fact that anywhere he travels he can be assured of a helping hand as well as recognition of his Fusion.
 
Whilst these pictures above were taken during the assembly of the test boat in Fusion's facility, the pictures at the below show assembly can be achieved in more simple surroundings.

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!!

Wizard sailing catamaran

The WIZARD is a 22ft sailing catamaran design that offers 5–6 berths in 3 cabins, standing headroom, easy trailing, stability AND performance. For the first time in a trailable catamaran there is a genuine double bunk.It is legally trailable world-wide behind a family car. One person can assemble and rig it in under an hour ready for launching with no heavy lifting (e.g. the mast is raised using the trailer winch).The Wizard is roomy. In its 22′ length there are 5 berths in 3 cabins for privacy (3 singles in the hulls and one double on the bridge deck), a separate toilet compartment. Galley and a dinette seating 5. There is standing headroom in the galley using a “pop bottom” in the bridge deck.It is fast, the computer predicts speeds of 10 knots under power (with a 15hp outboard) and 16-18 knots under sail (with the racing rig). These prediction have been well proven many times in practice. Yet it remains maneuverable and easy to sail single-handed. It has shallow draft and is beachable.Also check out the Sango 25ft, the big sister to Wizard ,on my website www.sailingcatamarans.com

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'

Mana 24 with decktent

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 .

The Seascape design will suit any entry-level multihull enthusiast offering many features found on a large cruising catamaran. The underwater hull design is aimed at efficiency with a reasonable payload capacity enabling extended cruising with coastal open water capabilities. The sailing performance will impress but is balanced against the surprising amount of space and comfort this design offers. The saying ‘good things come in small packages’ applies to this design with this feature-packed boat offering a good alternative for those itching to go cruising but still saving for that ‘ideal’ big boat. The trailerable aspect of this design allows for easy delivery and storage. 

The companionways into the hulls are accessed from the safety of the cockpit and are designed with off-the-shelf deck hatches to reduce the work and complexity typically involved in building a secure watertight hatch.  An integral box beam creates the back of the cockpit area and is the division between the cockpit and the aft deck. The box beam doubles as a seat the full width and also for the helmsperson each side.

Open aft Deck A unique feature of this design is the open aft deck directly behind the box beam. The well-powered 9.9hp high-thrust outboard engine is mounted centrally nestled into the deck and box beam for maximum protection.  The aft ends of the hulls have convenient low-set steps for easy access to the water.

Socialising Socialising and recreation have been well-considered even on this compact design with a stylish hard shade top sheltering the cockpit seating area. This could include all-weather side and front screens for rain and spray protection. While at rest a boom cover would provide shelter for the entire cockpit.

Extra berth The dinette could be easily converted to an extra double berth if required providing sleeping arrangements for 4 adults. The foredeck and tramps are also a spacious area to relax and lounge with a moulded two person seat set into the deck area in front of the mast.

Build System The build system has also not been forgotten with simple surfaces and shapes to this design. Only flat panels are used in the construction with no complex shapes to contend with. If a kit system is chosen this boat is very quick and easy to assemble with all parts cut to size. Material options include cost-effective Gaboon plywood, plain foam or Duflex (choice of balsa or foam core).

If on a budget, most 16 to 18ft off-the-beach catamaran rigs will suit this design or could be customized to suit. These can be bought cheap and could even be a temporary rig to get you on the water in the interim until a new rig becomes affordable.

Description

Additional information.

catamaran plans and kits

The ECO 55 power catamaran is an affordable DIY power catamaran. As the owner proved the boat is a capable coastal cruiser. The inside layout is the same as for the ECO55 sail version but the underwater shape is changed. The cockpit is wider and has a size of 1,45m x 2 m. With the bigger size normal deck chairs can be used. With a cockpit cover two more can sleep on the boat.

Accommodation is simple but practical.

catamaran plans and kits

Because of the easily driven hulls the boat will travel at about 12 knots with the a 15 HP outboard engine. But practice showed that a single outboard of 20 HP is more feasible - less noise and lower operating costs.

catamaran plans and kits

The boat has a double bunk, but the cockpit is big enough to sleep 2 more persons. The construction and list of materials is similar to the ECO55 sail version . The difference is that you need no rig, rudders or dagger board. With the low weight of about 325 kg including engines the boat can be towed behind a relative small car.

catamaran plans and kits

Construction is as always the plywood/glass/Epoxy construction system. The hulls are V-shaped with vertical sides - easy to build by a beginner. For cost estimation see the list of materials below.

  • All drawings are CAD drawings
  • Wood/epoxy composite for easy construction and low maintenance.
  • Sleeps up to four

Our kits contain all of your basic materials to build your boat to a faired shell stage, ready for painting and fit-out. We have sail-away costing estimates available for all of our standard designs, and this will give you an accurate idea of the overall cost of your project. This costing varies depending on your level of finish, as you can imagine different options vary greatly in price.

Below is a quick glance at what your Schionning Kit will include and what each item is primarily used for, we hope this is helpful and if you should require more detailed information please don’t hesitate to contact our office.

What do I actually receive?

Superlight Balsa - End-Grain Balsa - Foam - Paper Honeycomb - Western Red Cedar - SDI - End-Grain Balsa - 150kg per cubic metre Paper Honeycomb - 50kg per cubic metre Superlight Balsa - 94kg per cubic metre Western Red Cedar - 360-380kg per cubic metre - Foam

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.

Schionning Catamaran Kit Materials contain Kinetix Laminating Resin & Hardener Kinetix Laminating resin is used on all of our designs and is used for laminating the strip-planked areas, so round-bilge designs will use it more often whereas our flat panel designs not as much.

KINETIX LAMINATING RESIN & HARDENER

Resin Choices for Catamaran Kit Building by Schionning Designs SDI - We choose ATL Composite's resin systems for their superior quality, reliability and value for money. West System Epoxy Resins

WEST SYSTEM EPOXY RESINS

Fibreglass Tapes (Double Bias) These double bias fibreglass tape rolls are used for the joining of panels in our flat panel designs, or in round-bilge designs to a lesser extent. Anywhere that DuFlex panels need to be joined, tapes will be used. The smaller rolls come in different widths for ease of use and to save time on cutting larger rolls of cloth.

FIBREGLASS TAPES (DOUBLE BIAS)

Schionning Designs Catamaran Kit Materials Carbon Fibre Cloth Carbon fibre is used on a number of our designs and can be incorporated into any design to save on weight and increase the performance capabilities. Carbon comes in unidrectional and double bias, however is much more expensive than standard fibreglass (as one might expect). It is very similar to work with, however the resin choice may change when using carbon.

CARBON FIBRE CLOTH

Schionning Designs Catamaran Design Kit Materials Fibreglass Cloth Fibreglass cloth is the strength and stiffness that holds your boat together, this is used in most areas for strength and is used in a variety of techniques depending on the area or job that is being performed. Fibreglass is one of the most widely used materials for low weight and high strength properties.

  10. Catamaran Kit Process

    STEP 4. The fairing is now complete, this is done using a filler compound mixed with our West System epoxy resin and applied to the surface of the hull. This process is to ensure that when painted the boat will have a smooth and glossy appearance, and as a general rule the more painstaking the paint-job and fit-out, the higher your resale value.
