The FCS II Retro Performance Glass Keel Twin Fin Set features a low aspect keel template built for fish shapes with modern outlines and concaves. It has the lowest area keel in the range, delivering a fast and loose feel with minimal drag while supporting a more progressive and radical approach to riding a fish. Machine cut from solid fiberglass, the Performance Glass construction provides stiffness and consistent flex under high force and demanding conditions, and is designed to fit the FCS II Fin System for use across fish, funboard, and twin fin boards.
