I wonder. Spend a bit of time and cash on decent lifting foils and 3 or 4 carbon tubes to take the mast, shroud and forestay loads. A few bits of 4mm ply at about a tenner each for the minimalist hull, some plastic guttering tubes from B&Q for the rest of the spaceframe and trapezing racks and Fanny's yer Aunt, job done! Anybody else think it's possible?
