DUO 425 my first biplane (parallel) rig cat. Uses wind surf rigs. Easy to build. A hull has only 19 pieces. No boards, rudder automatic. Fast as hell
my first design (1980). As actual as ever.
More or less the same as DUO 425. Can handle any wind !!!
DUO 480 "jigsaw" pocket cruiser catamaran. Only 2,3m or 2,4m beam. Easy for road transport. Sleeps up to four. Again, easy to build and affordable. Plans show two different rigs to.
ECOnomy cruiser 5.5 A different approach as the DUO's. Symmetrical hulls and a single dagger board. Nice accommodation for such a small boat. Road legal in most countries. Fast boat to.
P5000 planing cat I lost this plan. A client has send me a copy. So the plan can be ordered again. This is the only plan available for DIY on the marked. Read the story and decide. It is an research project. Give away price for the plan is US $ 50,00.
