My grip is with plywood. Plywood have nothing to do inside high performance foils.

Details on "proper" build of a wood core carbon covered foil is most interesting!

What wood (species, fast grown/slow grown, weight pr cm3 etc).
Cutting and staggering of timer staves to avoid warp.
Laminate schedule.

I like wood! As in "I love wood!"
The material is cheap and strong, easy to work with, excellent durability, relatively lightweight, very environmentally friendly and so on.

With the Gougeon book available as a PDF for download I hope more people try their hand with wood.
