FCS II Nathan Florence Quad Fin

G10 is an industrial-grade epoxy fiberglass laminate known for its extreme stiffness and durability. In big wave surfing, this rigidity is crucial because it prevents the fins from flexing under the immense pressure of heavy water, ensuring your board stays stable and predictable when you need it most.

Yes, these are designed for the FCS II system, so they click in and out without the need for screws or plates. However, because they are specifically engineered for big wave boards like guns and step-ups, ensure your board is designed to handle the increased load of a quad setup.

The 50/50 foil on the front fins provides a balanced, neutral feel, while the 80/20 foil on the rear fins adds a bit more drive and hold. This combination is specifically tuned to give you the control necessary for high-speed, vertical surfing in powerful conditions.

No, these are specialized tools. The upright template and stiff construction are designed for speed and control in heavy, powerful waves. In smaller or softer surf, they will likely feel too stiff and draggy, making it difficult to generate speed through turns.

These fins are rated for riders up to 200 lbs. If you exceed this weight, the fins may not provide the necessary stiffness or surface area to support your leverage in critical, big-wave situations, and you might experience unwanted flex.
