I was thinking how strong is epxoy ply is compaired to other materials in boat building and found this on the net,very interesting. Better resistance to stress - Wood is the most resistant to constant direct force... the kind like the structure of a boat gets due to the pressure of the water on the hull. And the faster the boat goes, the heaver the force is. One well-known test was done on various materials to find out how well they hold up under constant pressure. Each material was put under direct pressure for 1 million cycles for 30 hours at a time. Straight Fiberglass kept only 22% of original strength Aluminum kept 37% of original strength Wood with epoxy kept 64% of original strength.

Thanks for that Mark

I've been wondering the best way to do the expanded plans ,the photo is from Rosses sandystraits 14, whats the best thing or material to use to get your curve lines ,flat ally or brass ??????.

Apparently theres a design fault with a self draining system, a ball gets stuck and lets water back in , thats what happend to the boat at pith reef and at magnetic island that was found sunk.
