The OMEGA 8.5m which is extendable to 9.4m is an aluminium power catamaran designed for coastal cruising and general rough water conditions. The basic design is for sheet aluminium plate. The hull is constructed from 4mm sides and 6mm bottom with the deck and coamings and flying bridge from 3mm plate. The hulls have been designed to accept 26" transom outboard lengths and twin 150h.p. outboards will give a top speed of approx. 35 m.p.h. and a cruising speed of 30 m.p.h. The hull form is symmetrical yea bottom hulls with a centreline planing strake 203mm wide. This hull form has good tunnel clearance for rough water conditions and the tunnel has been kept at approx. a third of the beam of the craft in width.

The interior layout consists of a double bunk ahead of the cabin with access through from the port hull. In the forward end of the starboard hull there is a shower and toilet area. The galley is down in the port hull in the saloon area while there is a large L shaped dinette which can be converted to a double berth up on the bridge deck area and extending into the starboard hull. The fuel tanks are in the hulls under the cockpit floor and the cockpit continues out between the outboard wells to the stern of the craft to form a boarding platform. The outboards are mounted in wells in the stern of the hulls to give good protection from spray etc. All the 26" shaft length outboards should tilt clear of the water when they are fully raised. The Omega has been designed as a high speed cruiser with a cruising speed of 20/ 30 knots being the design optimum. Because the Omega has been designed for sheet material, it can also be built out of plywood if desired. 9mm ply could be used for the hull sides and 12mm for the hull bottoms and up to the built in spray chine. The hull would be constructed over plywood frames which would be reinforced along the edges to allow adequate fastening of the plywood skin.

The plan includes FULLSIZE TEMPLATES of the frames, plus detailed drawings of hull construction, interior layout, etc. plus written instructions.
