C-C 25.5 Power Catamaran

This boat is designed to be able to be towed out, on a simple dolly trailer by the family car and parked on the hard to avoid the cost of a marina berth.

C-C 25.5 Power Catamaran – This is a development from the C-C 20 Trailer Cat. This boat is too wide to trail on our highways however it is light enough to be towed up a ramp by the average car, using a simple trailer (No brakes, no suspension, no registration, no other costs, just a trailer to move the boat to a dry storage parking spot.) eliminating the cost of a permanent mooring or marina berth.

She has the room and creature comforts for a family to enjoy boating on a budget. Starting with – An enclosed Tlt., Shower and vanity (Full headroom) that offers real privacy, a useful u-shaped galley with direct access to the large cockpit (can be enclosed), Two single bunks that has a table between them that converts to a dinette and a double bunk in the bow. Also  arranged in the cabin are the steering position and a seat for Mum (out of the sun and wind). This is a lot of boat for 25 feet and another good point, IT can be home built using the C-C KIT method of alloy frame construction. HOW GOOD CAN IT GET ?

C-C 30 Power Catamaran 

C-C 20 Through To The C-C 30 Power Catamarans

Like the C-C 20-31 Trailer Sailer the C-C 20 – 30 Power Catamarans were designed to take advantage of Compu-Craft KIT BOAT method of construction. Therefore it is not just a set of plans to build a boat BUT A COMPLETE NEW SYSTEM, a DIFFERENT quick and easy way to create a LIGHTER, FASTER more ECONOMICAL boat. This system requires no expensive moulds or throw away frames, waste is all but eliminated and it draws on NO special skills or tools and these advantages favour the professional boat builder as much as the amateur.  

The purpose of this design was to offer the Power Boat man a little more on several fronts. These advantages commence the day construction begins and most of them will remain with the boat for its entire life. For one, LIGHTWEIGHT offers Economy of Operation FOR EVER MORE. First it was decided (at least for now) not to incorporate a Fly Bridge, this reduces weight, windage and building complexity and is in keeping with our theme of SIMPLICITY. It is intended as a very PRACTICAL and ENJOYABLE boat to own, with all the comforts of home. As usual we will board over the stern, where, between the motors, there is a fold down cockpit extension that forms a swim and boarding platform, when lowered. It also allows the tender to be pulled up into the cockpit when under way (the extension folds up behind it). The cockpit is really the aft deck that extends from gunwale to gunwale. It is partly covered and provides a Fisherman's Service Centre (sink & bait board) with the gas bottle locker under, to Port and a comfortable seat (a fisherman's relaxation centre) to Starboard. On entering the saloon cabin there is a spacious U shaped Galley and Breakfast Bar to Port with the Dinette opposite. This can be raised a little to improve vision when seated. Forward to Port is the helm position with a large cosy lounge alongside so that the 'offwatch' can take in the vista and converse with the skipper when underway.  

Aft and to Port is access to the side deck through a sliding door or down to the Portside double cabin with lockers and full standing headroom. Back in the saloon cabin is a large bench to Starboard (for TV and the like) a short companionway leads to good sized, enclosed Toilet, Shower and Vanity with full headroom, and forward to a second spacious double cabin with the chart table forming the deckhead to this cabin. With the exception of the anchor winch all other tanks and machinery are confined to the Aft Deck and hulls. All this floating on two fine catamaran hulls that have been designed to perform well over a wide range of speeds and sea conditions with special consideration directed towards a friendly motion and minimum wash. A s mentioned on our Home Page under SPECIAL PROJECTS and Compu-Craft KIT BOATS, this system calls for a WHOLE NEW APROACH to boat building.  

This project will just click together in about as many hours as most other methods take days. THATS RIGHT it takes only a FRACTION of the time normally expected. The entire frame for the hull, interior and cabin structure is made up of a combination of square and circular alloy tubing. Fixed together with a range of specially designed (patented) C-C clamps (joiners) that do not rely on welding or gluing. They mechanically grip the tubing and are locked in place by a few pop rivets. NOTHING COULD BE SIMPLER OR QUICKER.  

The BIGGEST ADVANTAGE is the finished boat ready for your first weekend afloat with Motors, Fuel, Water, Mum and the Kids even the Lamingtons on board will DISPLACE LESS THAN FOUR TONS. This means about One Litre of fuel per Nautical Mile cruising at Ten to Twelve Knots. It is economical to 15 Kts. with a top speed of 20 Kts., using twin 50 HP Four stroke outboard motors. An even cheaper alternative is Two 25s that will offer day-long cruising at 8 to 10 Kts and a top of around 14 Kts, of cause if speed is your thing WHACK A TEAM of THEM on the back and watch the scenery DISAPPEAR.

C-C 30 Power Catamaran

Like the C-C 20-31 Trailer Sailer the C-C 20 – 30 Power Catamarans were designed to take advantage of Compu-Craft KIT BOAT method of construction.( Now includes boats up to 39 feet - 11.9m ) Therefore it is not just a set of plans to build a boat BUT A COMPLETE NEW SYSTEM, a DIFFERENT quick and easy way to create a LIGHTER, FASTER more ECONOMICAL boat.
