60 ft L 15 ft W powered by twin outboards and 2 unstayed wingmasts mounted on the inside of each hull apposing each other. We decided to build a 35 ft boat and then add 10 ft to the bows and 15ft to the sterns as this is the cheapest and easiest sections to build. We are building long thin planing hulls with a twin foil system to achieve a plane between 10 - 15 kts at max gross weight.
