  • Overview

    UNIQUE TEMPLATE

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

    • SIDE FIN PROFILE: Lower section produces maximum acceleration, while hatchet like tip creates stability & control.
    • CENTRE FIN PROFILE: Highly raked elliptical outline reduces drag, and offers 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.

    Excellent Fins

    Used these fins on a board I have surfed for years. It made it feel like a whole new board. Excellent speed and performance.

    Better fins ever

    They are so better in good waves that it's incredible, on the other hand in 2-4 feet waves the center fin is a kind of stick on tight turns.

    I've sold some of my other fins in order to get these ones and I'm so happy on that.

    I'm looking forward to get a center in medium size to try on small conditions.
