FCS II Al Merrick Fins

These fins are specifically designed for performance shortboards that feature deep concaves and moderate-to-extreme rocker. They excel on boards built for high-performance surfing in critical, hollow waves.

The Tri-Quad setup offers maximum versatility. Using the thruster (tri) setup provides a predictable, pivot-oriented feel for tighter turns, while the quad setup adds speed and hold through rail-to-rail transitions, making it ideal for faster, down-the-line waves.

The smaller center fin is engineered to reduce drag and allow for a quicker, more responsive release when you initiate turns. It ensures you can break the tail free easily during high-performance maneuvers without sacrificing the drive generated by the larger side fins.

The multi-layered resin transfer molding process creates a consistent, progressive flex pattern. This means the fins feel stiff enough to hold through powerful turns but flex enough to provide a lively, responsive feel as you load up and release energy.

No, these are FCS II fins designed specifically for the FCS II tool-less fin system. They will not fit into older, screw-in dual-tab boxes.
