FCS II JS Fins

These fins are specifically designed for performance shortboards that feature deep concaves and moderate-to-extreme rocker. They are engineered to complement boards that need help generating speed while maintaining control through tight turns.

The tri-fin setup provides a more traditional, pivot-oriented feel that is great for vertical surfing and quick direction changes. Switching to the quad setup increases speed and hold, making it a better choice for down-the-line surfing on faster, open-face waves.

While they can certainly be used in beach breaks, they really shine on point and reef breaks. Their design prioritizes flow and drive, which is most effective when you have a longer, open face to work with rather than the quick, punchy sections often found at beach breaks.

No, the FCS II system is designed for tool-less installation. You can simply click the fins in and out of the box by hand, making it easy to swap between your tri and quad setups right on the beach.

The primary goal of this design is to balance speed with a reliable release. It allows you to push hard through turns without feeling like the board is tracking too much, giving you a smooth, predictable ride that doesn't sacrifice drive.
