Looks like 50-60 oz, with additional reinforcements is correct. I'd build it like a wing, with a very strong full-depth spar right at the CP/ thickest point of the foil. Basically, tying the two skins together as they will be stressed. Fiberglass does way better under tension.
Looks way more complicated based on those threads, but possible. Good luck![/quote]
