here is the cutting edge of surf kayak design as of 3 weeks ago.
both of these boats have ther cockpits well behind the center, this is to enable you to surf from the tail like the new wave skis.
Nick your original design that showed a chine that might have been right on!
the vortex (moddled after the new west african wave skis)
These surf shreading machines should be facing off on feb. 6 at the Jalama Expresion Session.
I hope to be at Jalama. More info later
