JP’s design for top speed on a reach. Both the profile thickness and the profile length (cord length) are reduced to their minimum which ensures least drag and optimal downwind speed.
The good twist of this G10 fin provides excellent control at top speed.
The widest point of the profile is slightly further back, creating less drag and consistent lift throughout the whole wind range. In additions to this, constant twist and flex make the fin very predictable. There is no tendency for the nose to lift off the water, resulting in incredible control and top speed
