Derived from a longtime favorite template, the FCS II AM PC Twin Fin Set delivers a loose and speedy ride that, with the addition of the mini stabilizer, can easily be controlled. The AM PC Twin is Al Merrickā€™s original twin fin template, with further refinements from Rob Machado and the shapers at Channel Islands. The side fins have a wide base and a long leading edge running into a narrow tip, this provides great trim speed, with the ability to quickly break into a turn.

The very low sweep angle and subtle curve on the trailing edge means this set will pivot in a super tight radius, while maintaining sufficient hold characteristics when pushed a little harder through a turn. Being the lowest area twin set in the FCS II range, the AM PC Twin Fins pivot and release exceptionally well, require minimal effort to turn off the top, while maintaining incredible speed and acceleration due to the lack of resistance typically caused by a larger center fin.

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.

GREAT fins! Turns your thruster into much more of a twin (not a true twin, but super loose).
