Ride like never before with the FCS II AM PC Tri-Quad Fin Set underfoot. Offering extra versatility, these two essential AM sets allow you to customize your fin configuration to suite the swell size and break type. Enjoy the precision control of a thruster or the skatey flow of a quad with the signature Merrick shape powering you down the line. These performance fins deliver the crucial speed and drive that is vital to vigorous carves, quick turns and launching above the lip. For decades the AM template has proven its worth. Whether in intense pumping conditions, deep cavernous pits or demanding beach breaks there is an AM to suite surfers of every size and style.

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.

50/50 FOIL

A symmetrical foil used on all center fins where both sides are convex. Even water flow on both sides creates stability and control.


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.

***Exclusively for the FCS II Fin System; will not fit in the traditional FCS Dual Plug System***
