Well actually the biggest drawback of wood (marine timer) construction is the labour involved in folding up a set of hulls. It also requires a higher skilled workforce. As today labour is a very expensive cost component glass-vinylester wins in the economical sense when trying to make a living off it. Sadly marine ply + epoxy wins in the engineering department. So we are all faced with a choice.
That is unless we can get some cheap skilled labour force in some asian country and have the timber epoxy hulls produced there with a single (light) layer of glass to enhance impact resistance some more. THAT would be the ultimate hull. Thanks to Phills efforts we can make a little bit more complex shapes with folded ply.
