Does anyone know of any good plans to build a solid but lightweight rowing/sailing dinghy? Ideally I'd like to build it out of something light like divinicel and fiberglass (sandwich). Something about 8ft should do the trick. The idea is to haul it up on deck when sailing so I'd like something light. Has anyone built one they could recommend? Has anyone tried building one using a foam/fiberglass sandwich technique? Thanks in advance!
