How To Build Kit Boats

Our KIT BOATS:- Incorporate our patented (pending) fittings and methods that result in the following advantages.

This is a unique and extremely quick way, for the unskilled, the inexperienced, the amateur or professional, to build a boat. That is LIGHT, FAST, ECONOMICAL and FUN to build and own.

We have combined the best of traditional methods and proven techniques with some fresh new thoughts on framing and fixing, using tubular aluminium (aluminium) in place of timber. The result is a much lighter boat that has a fibreglass finished exterior and a panel fabricated interior that eliminates the need for:-

8. Alloy tubing is cut to length directly off the FULL SIZE drawings and just CLICKS TOGETHER with a few rivets (using a hand Tool) and our SPECIAL C-C CLAMPS (joiners).

9. All the JOINERS, TEMPLATES and GAUGES, for this operation are in the kit.

The fit-out inside the boat is SIMPLY and QUICKLY achieved with flat panels such as plywood, Laminex, Forminex, melamine, foam/glass com. or any other lightweight panels fixed directly to the alloy frame. (With self tapping SS screws.) There is little waste, little skill, minimum cost and time required using only the simplest of hand tools.

In the past the big bugbear of all timber boats has been ROT. It is the one thing that will try to destroy YOUR boat, if the conditions are right. This method of construction eliminates ALL of the TIMBER FRAME, so it can NEVER ROT. If you use plywood as the skin, it can be treated during manufacture against rot, it can be epoxy saturated on the inside and glassed on the outside and that problem is virtually GONE.

We have built one of the Trailer Sailers using this system to make sure all the bugs were ironed out before offering them to the unsuspecting. This boat went together in surprisingly short time and has proved to be very stiff and light. In all a great little boat. This method is so quick (labour saving) and inexpensive that even professional boat yards could provide a finished boat at a very competitive price. (Yes agencies are available)

The intention is to add more designs to this range of Kit Boats in the near future.(This has been achieved, most of our designs under 40 feet, 12m, are available for Alloy Frame construction.) So if you want a very easy and cost effective way to own a boat, keep this site in mind.

Contents of KIT & Plan Pack:-

It contains a full set of Lines Drawings and perspectives, FULL SIZE frame and bulkhead drawings, details and FULL SIZE patterns of the stem profile. Cabin construction details, accommodation layout details and dimensions. Plus a collection of C-C clamps (joiners) of appropriate styles to suit this design, a series of gauges and jigs and any other fittings and articles that go to make the construction job quicker and easier for the builder or that may not be available in his locale. Together with a list of materials (their description and dimensions) such as Resin, Fibreglass, Paint and Fillers (that cannot be transported internationally), Aluminium tubing and Plywood that can be obtained locally (saving on international freight costs).

You will notice that this is not a full knocked down kit of all the components needed to build your boat. What it is:- Is a collection of the Technology, Drawings, Instructions and Information together with items, aids and materials that combined with common supplies that are readily available in almost any part of the world, will collectively make-up your boat. This is the quickest, easiest and cheapest way you can take advantage of this system.

Oh yes and a little effort from yourself, but that'll be FUN.

Total Building Cost:-

To enable you to establish approximately how much it will cost you to build your boat, each design contains a list of articles and their quantities that you will need to purchase locally to complete this boat, along with the Compu- Craft KIT & Plan Pack.

These figures are approximate only and the list may not be complete, (We make every endeavour to ensure their accuracy.) they are meant as a guide and an effort on our part to help you gain quotes and prices to assess the likely cost of your venture. We realise that Compu-Craft¹s NEW KIT method of building, has several SPECIAL FEATURES:-

(ONE). IT IS THE CHEAPEST, MOST COST EFFECTIVE way to build a boat with an overall length of 15 to 40 feet. (4.5m to 12m)

(TWO). THIS IS THE QUICKEST way to build a boat.

Until now the 'dry assemble strip plank method' was the quickest. Compu-Craft pioneered that system nearly Twenty years ago. Now these C-C KITS require LESS TIME, LESS SKILL and NO SPECIAL TOOLS. (THREE). THIS IS ALSO THE LIGHTEST (-20% for the frame) way to build a boat.

NOW !

After 2,000 years of building timber boats, 150 years of building steel boats, 50 years of building boats in alloy, 40 years of fibre-glass (Tupperware) lookalikes.

THEN EUREKA !!!

We discovered VERY COMPLEX ways to create VERY EXPENSIVE EXOTIC materials. (carbon - Kevlar - nomax - foam - epoxy - polyurethane ++++) and THEN we developed VERY COMPLEX and VERY EXPENSIVE methods (male plugs, female moulds, pre-pregs, vacuum bags ++++) to build boats with these materials. We called this COMPOSITE CONSTRUCTION.

Using all these HI-TEC materials (Imported from Everywhere) combined with HYPER SKILLS and EXPERIENCE. We have managed to turn out a small number of gutted out speciality racing machines at EXORBITANT COSTS and these boats have Two VERY SPECIAL FEATURES (Beside their cost).

They are structurally far LESS RELIABLE and a LITTLE LIGHTER than yesterdays siblings.THIS IS HARDLY THE WAY TO GO !

 To THE AVERAGE SAILOR who just wants a LIGHT, FAST boat that is FUN to sail and CHEAP to build and maintain. 

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

NOW THERE IS A NEW WAY TO GO !

TO HELP introduce the Compu-Craft KIT method to the scene, we now have the C- C 16 ROWING SKIFF or DORY. This is a simple craft designed for no other purpose but to be FUN TO ROW. HOWEVER THERE IS A REASON for this design and that is to OFFER A CHEAP and EASY OPPORTUNITY for a potential builder of one of our KIT BOATS to TRY THE METHOD. If you think this system has anything to offer. THEN HERE IS A CHANCE at little expense to learn first hand the benefits of the Compu-Craft KIT system. The C-C 16 ROWING SKIFF is constructed using the same standard Compu-Craft C- Clamps and tubing, methods and materials as is used in the bigger KIT Boats. The purchasing, pricing and procedures are all the same. ALL THE REQUIREMENTS are the same. THIS WHOLE EXERCISE is designed to allow you to do a TEST RUN, before being expected to part with YOUR MONEY and embark on a project that somebody on the other side of the world claims IS A GREAT IDEA. BUILD a C-C 16 Rowing Skiff :- It¹s CHEAP, It WILL be GREAT FUN and you WILL REALIZE how SIMPLE and QUICK this method IS.

NOW ?

LETS GO STEP BY STEP THROUGH THE PROCESS OF BUILDING A BOAT ?

Using the Compu-Craft Easy-Build KIT System.

You have settled on a design, purchased your KIT and at least some of the items from the materials list. Take the FULL SIZE frame drawings and tile them together on the floor or bench top. Using the gauge for skin thickness and a short piece of 40mm round tube on end, place a C-C clamp at the keel and another at the chine of the transom frame, place a length of alloy square tube along side the clamps and mark its required length and cut the tube (There is room for about an inch [25mm] of error), so you don?t have to be precise, slip the clamps into the ends of the tube, place these onto the plan and locate in line with the drawings. Drill and rivet one clamp to the tube, check with the plan, drill and rivet the other clamp to the tube. Take another clamp and place at the gunwale and another at the chine on the plan (using the skin thickness gauge), cut another length of tubing and rivet it to the clamps and rivet the clamps together at the chine. Repeat this process to construct the other side of the transom frame. Place and screw a length of tube across the frame at a waterline that is appropriate for your building site or as suggested on the plan and YOU have just completed the first frame, STOP FOR A CUPPA and marvel at how simple this boat building is.

Using this process complete the rest of the frames. Take two adjacent frames and some lengths of tubing (or timber battens) as temporary bracing and set up the frames in the position where you wish to construct your boat. These frames should be vertical, parallel to each other at the correct distance apart (as stated on the plans), the tubes set parallel to the LWL when making the frames will determine the height and allow you to level each frame. Approach each of these steps one at a time and it is easy. Repeat this setting up until all the frames are in place and temporally braced. This will take far less time than you have imagined so a cup of tea and a little self praise is in order.

Take two lengths of square tubing (stringers) and place them approximately the correct distance (see plan) each side of the hull centreline and pull (spring) them into position and starting at the transom, fix with two SS screws to each frame (fit the stem later). Next take a round tube and fit the keel. Repeat this process until all of the stringers, chines and gunwales have been fitted, now cut a length of round tube and bend to shape as described in the plans for the stem, offer this up to the stringers and position so as to mark and cut the tubes to length and fit the C-C clamps (do not rivet together yet) relocate the stem in place and adjust until correct, now drill and rivet the C-C clamps to fix the stem in place.

STOP STAND BACK and take a photograph, you have finished the fame of your boat and it is now ready to plank-up. All without any SCAMPERING, no FAIRING, no WELDING, no FIBREGLASSING, no DRAMAS and in the shortest of time.

Now a few other things will be apparent at this point, the worksite is clean and tidy, (No sawdust or shavings, no hot pits of metal and best of all NO ITCHY dust.) the frame is VERY stiff and strong, it is VERY fair and accurate and you are now ready to start the planking in whatever panels you have chosen. (Ply, foam or glass.) THAT IS HOW SIMPLE IT IS!

When you peruse the plans, the details of each frame will show the appropriate framework and panel information for the furniture and fit-out at that frame. If this work is carried out at the time of constructing each frame then this will speed up the fit-out and it is easier to do this work on the workbench than it is in the boat. Keeping in mind that the frames are positioned to coincide with the fit-out and structural bulkheads, during the planing. So I would recommend that this process be adopted. It WILL save time in the long run.

C-C Trailer Sailer C 

If you intend to plank the boat with marine plywood, then I would suggest that you purchase ply that has been treated against mould and rot and before fitting to the hull apply a liberal coat of epoxy resin to both sides of each panel.

The gauges supplied in the Compu-Craft KIT will speed up the process of cutting and shaping each panel. Compu-Craft plans are established using conical developed surfaces so that the planking panels will fix directly to the frame without buckling or demanding any force or preshaping. The planking is bonded to the frame (polyurethane) using SS screws as the clamping and secondary fixing.

When the planking is completed the seams are filled and faired and the exterior of the hull, decks and cabin tops are fibreglassed to protect it from the weather and wear and tear before being painted and finished off in the normal manner.

The interior fit-out is constructed over an alloy frame using the same methods and materials as the hull. This is achieved in short time, requiring no special skills as the frame can be conveniently attached to the hull frame using C-C clamps and fittings (NO fibreglassing). Tanks and other gear can also be fitted in the same way.

C-C Trailer Sailer A 

This finish didn't take days, weeks or even months on torture boards to achieve, it took only a few hours (the paint was hand brushed).

TOOLS and GEAR REQUIRED

Most woodworking tools can be used for fabricating the alloy frame. We have built a twenty foot (6m) trailer sailer using all hand tools (no power) without difficulty.

However I would recommend :-

ELECTRIC - Jigsaw, A lightweight Drop or Cut-off saw, A bench Grinder and Linisher (would be handy), A portable Circular saw, A couple of Battery Drills (Screwdrivers), An Angle Grinder (100mm).

HAND TOOLS - Hacksaw, Files, Hammers, Panel saw, Screwdrivers, Pop Rivet pliers, Spirit Level, Rulers, Tapes and Scraper.

CONSUMABLES - The usuals, sand paper, pencils, brushes, rollers, gloves and other safety gear.

This method requires nothing special in the way of equipment, tools or skills.

The Compu-Craft plans and KITS are detailed and come complete with instructions and aids to assist the builder, to avoid difficult tasks and save money wherever possible.

ASSISTANCE We can be contacted by telephone, e-mail, post or in person during your building process to answer your queries or comments AT NO EXTRA COST and if you can offer advice or shortcuts that may help anyone WE WOULD LOVE TO HEAR FROM YOU. PROGRESS REPORTS AND PHOTOGRAPHS We would be very grateful for any info, we would even like to hear you BOAST a little. Newsletter Material.

REMEMBER THESE BOATS ARE CREATED FOR YOU TO HAVE FUN.
