Why are only carvel boats "real wood"? Last time I looked (yesterday) the hull of my double-diagonal 28' cruiser/racer was made of real wood, just arranged in a different manner to a carvel boat.
Even at the end of the wooden boat era (ie the late '60s/early '70s) the traditional yacht builders around here (Australia) had normally moved to cold moulding for yachts. It's not that they didn't have the skills for carvel; it's that they thought carvel was inferior in many respects. The attitude that carvel makes the only "real" boats isn't very inclusive and maybe such an attitude is part of the problem.
