Fin control in a straight line is one thing. Turns are another. Get the fin wrong for stronger winds and you get either spin out or tram tracking. Anything that gives the control back to the shape of the board during turns also has to be a good thing.
The pressure differential idea is good. So a technology that exploits what in car racing is called downforce, in the right place, without increasing drag would be a good thing. To the uneducated, like myself, these objectives seem mutually incompatible with a craft that planes like a WS; but then again my knowledge of hydrodynamics is pretty basic.
