FCS II Sharp Eye Fins

These fins are specifically designed for performance and hybrid shortboards. They pair exceptionally well with models like the Sharp Eye Inferno FT, where the fin geometry complements the board's rocker and bottom contours.

The smaller rear fins are intentional; they reduce drag and allow for a quicker, looser feel when you're transitioning between turns. This setup gives you the hold of a quad configuration while maintaining the snappy, responsive release of a thruster.

These are FCS II system fins, so they are designed for boards equipped with FCS II fin boxes. They are not compatible with traditional dual-tab boxes that require screws.

These fins are optimized for riders up to 200 lbs. If you exceed this weight, you may find the fins lack the necessary stiffness and drive to hold through powerful turns.

The flat inside face is engineered for speed and immediate response. It creates less lift than a foiled inside face, making your board feel more reactive and easier to pivot when you initiate a turn.

Because this is a five-fin set, you have the flexibility to choose. Use the thruster setup for more control and predictability in punchy beach breaks, or switch to the quad setup when you want extra speed and drive in critical, overhead conditions.
