Designed by Al Merrick for radical, progressive surfing, the FCS II Al Merrick PC AirCore Tri-Quad Fin Set blends raked side fins for speed and drive with a smaller center fin on the medium and large templates for quick release through turns. Built with updated Performance Core construction and ultralight AirCore, the five fin setup excels in hollow, steep waves and punchy beach breaks, pairing best with performance boards featuring deep concaves and moderate to extreme rocker.

Product Construction
Performance Core + AirCore
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 Construction is light and can be used in a variety of different conditions. Fins with AirCore Technology feature a pressed polyurethane foam core that mimics the geometric Foil of the fin. AirCore technology reduces the amount of Fiberglass required in the RTM molding process making it much lighter while allowing total manipulation of the flex.
