Wouter,

I have no interest in getting in a fight with you. I became involved in F12 because I want to kids sailing, not to see my name in lights. Please keep this sort of discussion for elsewhere as it doesn't do any class F16 or F12 any benefit to have arguments in their forums when these represent the class's primary public face.

There is nothing in the rules that stops your ideal boat being built. Get it on the water and show us how wrong we were.
