If the boards were short enough then for sure you can do it in wood, but with the aspect ratio and foil section shape of current F18 foils..... no way is it possible to do in wood.

Most builders are struggling to build unbreakable foils even in carbon.. If you want them to be perfect then you need to spend big bucks to build them right.

I reckon 1600 USD is pretty ok for a pair of wildcat boards, they will be really good in an F16
