FCS II Al Merrick Twin + Stabiliser Fin

These fins are specifically engineered for hybrid and twin-plus-one surfboard models. The offset trailer fin tightens the cluster, providing the control needed for these specific board shapes while maintaining the loose, fast feel of a twin fin.

The upright template is designed for tight-radius pivoting. Because the fins have a low sweep, they allow you to make quick, sharp turns in the pocket rather than drawing out long, sweeping lines.

The offset trailer fin tightens the cluster, which helps stabilize the board during turns. This configuration bridges the gap between the loose feel of a pure twin fin and the drive and hold of a thruster setup.

Yes, the Performance Core construction features a progressive flex pattern that maintains drive and hold through turns. While they are built for speed and quick release, the robust base ensures you have enough stability to handle varied conditions.

The narrow, tapered tip is designed for fast and easy release off the top of the wave. It minimizes drag at the end of your turn, allowing you to transition quickly into your next maneuver.
