FCS Power Twin Stabilizer Fins

The trailer fin acts as a stabilizer, providing extra control and hold during aggressive turns. It bridges the gap between the loose, skatey feel of a traditional twin fin and the predictable drive of a thruster.

These fins are designed for the FCS II fin system. If your board has FCS II boxes, they will click in without the need for screws or plates.

Performance Glass is stiff and durable, which translates to a very responsive and consistent feel. It is designed to hold its shape under high pressure, making it ideal for surfers who want to push hard through their turns.

This setup excels in a variety of conditions, but it really shines when you need extra speed and drive. The large base helps generate momentum in weaker waves, while the stabilizer provides the confidence needed to handle steeper, more powerful sections.

Yes, you can remove the trailer fin if you prefer a looser, more traditional twin fin experience. However, the set is specifically engineered to work as a cohesive unit, so you may find the board feels significantly different without the stabilizer.
