FCS2 x Rob Machado Performance Glass Extra Large Quad Fin Set, a semi-keel fin with small stabilizers derived from pro surfer Rob Machado's RM Keel Twin template. This design takes a full-size keel shape and converts it into a quad set by extracting area from the back of the keel to form a robust, low-profile mini trailer rear fins. This set blendw the loose, fast flow of a traditional twin fish with the predictable bite and tight-turn control of a performance quad setup. The large surface area and smooth curves deliver fast take-off acceleration, high drive, and plenty of speed down the line.

Performance Glass (PG) fins are machine cut from layers of solid fibreglass. PG fins have very fast memory recall which translates into speed. These fins are stiff, providing immediate response and acceleration as the surfer powers up and drives through a turn, while maintaining flex integrity under immense force and in extreme conditions and situations.
PG fins are widely used by pro-level surfers.
