FCS Split Keel Quad

These fins are specifically engineered for traditional fish and hybrid boards that feature wider tails. They are best suited for boards with moderate-to-low rocker, where you need extra stability and hold to manage the board's volume.

Performance Glass is a solid fiberglass material that provides maximum stiffness. This results in a very responsive, predictable feel that holds its shape under high pressure, making it ideal for surfers who want a reliable, stable connection to the wave face.

The Split Keel Quad is designed for the FCS II fin system. If your board is equipped with FCS II boxes, these fins will click in seamlessly without the need for screws or plates.

A standard quad setup usually prioritizes speed and loose turns. By using a keel template, this set adds significant surface area and bite, giving you the control and hold typically associated with a twin-fin keel, but with the added stability of a four-fin configuration.

These fins are generally geared toward experienced surfers looking to fine-tune their board's performance. The stiff flex and high-area template require a more precise technique to get the most out of them, so they may feel less forgiving than a standard, more flexible fin set.
