Two curved mould halves indeed sounds as a large (too large) commitment. But as long as the mould halves are straigt I actually believe I should be OK. I work at a company making carbon fibre composites for aero and auto inustry, so I have acces to equipment beyond the normal hobbyist. I am naturally going to discuss this with a sailmaker, but would still like to have some ballpark guess to be able to understand and ask him the right questions.
