Who cares what the science of the box is? Since when has the hydrodynamics of windsurfing been fully explained. The best shapers do not spend time running computer simulations to make a new design, they just try it and that's half the fun. Fun is what this sport is all about.
The idea of not having a fin is something I would love to hear more about though. This is thinking outside the box*
Te only comment in that article I thought was odd was the one saying he would like to make it possible to windsuf in no wind...WTF, surely the wind part of windsurfing gives something away there.
*Widestyle was outside the box at the time, loose leach sails was outside the box at the time. Anything very different has to be considered outside the box.
