i dont think you should use wood at all....
make the hull from insulation foam, then fiberglass over it...but when you fiberglass, use epoxy resin, not the polyester resin, that stuff eats foam...
foam is easier to work with as you make the hull from a solid block, its lighter, and it floats already, no need to worry about flotation....
maybe the only peice of wood you might want to use is where the motor mount will be, just to have a solid base to attach it to..
Saleens dont discourage the kid from using wood or balsa you never know what he likes!!! or how good of a builder he really is!!!
Althought foam may be easy to build with, but wood can be a much more creative way to build with and lighter if build right it all depends on the structure of the model.
Maybe you have never actually attemted to build with wood!! Ha what maybe[:'(]
