Initially created to develop fins for single fin High Performance longboards that have a tail width narrower than 15" and hard rails. The HP fin has a full sized base for great drive, a considerable amount of rake and a significant reduction in the neck area that creates the "wag: that these fins are renowned for. The "wage" flexes like the tail of a shark when you enter a turn, then snaps back, producing an unprecedented thrust when you exit the turn.
