I am going to use fiberglass cloth and epoxy resin, I have 2 oz cloth already and the hull is not to curvie, I would use 3/4 oz if I had it. I will use 3/4 oz if the 2oz does not pre fit well, the nose has two carved balsa blocks, most of the hull is 1/8 x 1/2 balsa, the inside is done with 6oz cloth and epoxy resin, some of the flat sides ara sheet balsa and some of the 1/8 x 1/2 strips were cut down to make it easier to bend, I used about 15 frames, and when i had them right it made the planking easier.
