FCS II Al Merrick Thruster Fin

These fins are designed for performance shortboards, specifically those featuring deep concaves and moderate-to-extreme rocker. They are engineered to complement boards that need extra drive and control in demanding, high-performance conditions.

The smaller center fin is designed to reduce drag, allowing for quicker release and tighter, more responsive pivots. It makes the board feel looser and more maneuverable through turns compared to a standard thruster setup.

Yes, they excel in punchy beach breaks where you need to generate speed quickly. While they are built for hollow, steep waves, their design provides the versatility needed to navigate the varied sections found in most beach breaks.

The Performance Core material uses a multi-layered resin transfer molding process to create a consistent, progressive flex pattern. This ensures the fin feels stable at the base for drive while providing a snappy, responsive feel through the tip during turns.

No, the FCS II system is designed for tool-less installation. You can simply click the fins into the box and remove them by hand, making it easy to swap setups on the beach.
