Power Trimaran Plans. Looking to buy a boat but feeling uninspired by conventional designs. Welcome to the old website of McGowan Marine Design Inc featuring the design and experimental work of Laurie McGowan.
Searunner Trimarans were designed by Jim Brown and are offered in 5 sizes. 1968 OSTAR Atlantic proa. - max draft 4ft.
60 Power Trimaran - Aluminum plywood or GRP.
The SC10 has a one-design bendy mast sail plan with optional spinnaker. The original request was for a power tri with traditional styling. Fast fun. The idea of a better power boat.
