>>> Anatomy of a 46' Offshore Power Catamaran...

http://www.geocities.com/seageme/Offshore_Powercat_46.html?1007520842127

This is Hull #2, that should hopefully make it to the Miami Boatshow in February...

Please, note the narrow entry, deep forefoot; 3' high bridgedeck clearance to avoid slamming; narrow beam on the water line; wide knuckle some 6" above, to deflect spray, provide additional bouyancy and adequate room inside the hulls; keels that extends aft and fully protect the Propellers and Rudders, giving 3'2" draft; fore and aft stiffening stringer that runs the length of the bridgedeck; wide Radius connections between bridgedeck and hulls... and the harmonious lines....

This non-planning/displacement hull slices through the water quite efficiently, with a very soft motion and flat trim... It is capable of about 25 knots, using approximately half the power required by a planning monohull, say twin Yanmars 230 Hp and can cruise at 16 knots, getting around 2 to 2.5 miles per Gallon... 1000 gallons fuel would allow Transatlantic range with the usual stops in Bermuda and Azores...

With an 18'6" beam, the cockpit is huge at 10' x 17" and the salon is some 15' x 17', with panoramic 360 degree visibility, whether seating or standing... It includes full galley, large settee/dining, Nav/piloting station and entertainment centre, without forgetting the cellar for the Mouette...

Down in the Hulls, up to 4 spacious double cabins and 2 Heads are easily accommodated, leaving plenty of space for a Utility-room/workshop... At anchor, the design provides a perfectly stable platform, not affected by the usual wave induced rolling and there is a comfortable Flybridge to complete the picture...

This is quite an exciting project, bearing in mind, that there are so many advantages to this Formula, that I expect the displacement Power Catamaran to become a very popular design in the US....
