  • Overview

    UNIQUE TEMPLATE

    Radically different side & centre fin templates create a powerful fin set with ultimate speed & drive.

    • SIDE FIN PROFILE: The lower section produces maximum acceleration, while the hatchet like tip creates stability & control.
    • CENTRE FIN PROFILE: Highly raked elliptical outline reduces drag, and offers a feeling of predictability when releasing through turns.
    • FIN FOILS TEMPLATE: Thicker base with tapered tip optimises flex & regulates the release of energy during rail-to-rial transitions.

    Ideal Conditions

    • A wide range of conditions, particularly good in critical overhead waves.

    Board Types

    • Designed to fit the FCS II Fin System.
    • Recommended for performance shortboards with moderate-to-low rocker.

    Fin Family

    • Accelerator: Find Control. Speed, flow and response with added control.

    Best fins I ever tried

    Tried them out for the first time this weekend and WOW. I had my every-day board (5´8 swallow tail, epoxy) and I felt a huge difference in both control and speed. It was like these were effortless and more natural; like I didn't have to work as hard to gain speed or to keep control of board even in the punchy waves I was surfing (beach break in Rio). On top of that, the board responded really well on tighter / faster turns. I still want to try them out in other conditions, but my first impression couldn't have been better. Definetly the best fins I have ever tried!
