World Longboard Champion Harley Ingleby's Athlete Fin.
Harley's XL template delivers maximum speed and drive for powerful surfers.
Ideal for performance longboards, and surf SUP's.
Designed to be used with the FCS II Fin System.
Performance Core (PC) fins are made using a multi-layered resin transfer molding process. The flex pattern in PC fins extends progressively from the base through to the tip, helping the surfer to maintain drive and hold through a turn. This versatile fin material is light, and can be used in a variety of different conditions.
