Replacing the G-AM, the FCS ARC Fin has the same exact template with a new name and an updated look. Complete with a racing stripe, this fin was designed for fast on-rail surfing. The raked side fins produce exceptional speed and drive, while the smaller center fin offers quick release through turns. For the best results use this fins on open face, down-the-line waves in your performance board with a shallow concave and moderate-to-low rocker. These fins are particularly good in point and reef breaks.


Versatile RTM construction delivers a consistent feel similar to a traditional fiberglass fin, but with the advantage of reduced weight. The stiff flex pattern extends progressively from the base through to the tip helping the surfer to maintain drive and hold through a turn. PC fins are reliable, very responsive, and can be used in a variety of different conditions.


A flat inside face combined with a convex outside face. The traditional flat sided foil offers an even combination of drive, pivot and hold and provides a very consistent, reliable feel over a wide variety of conditions.
