Building the boat is easy. The builder simply assembles the hull as a strip plank hull first, then glasses the outside and inside with fiberglass, to produce a strong composite hull without all the time consuming woodwork associated with traditional edge naile strip planking. Bog, fair, paint then time for the internals. Its that easy
