  • 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.

     


  • NEW CONSTRUCTION
      • PRECISION SWISS ENGINEERED: Creates perfect synergy between fin geometry & HI-FI materials, giving a smooth & predictable feel.
      • HIGH-DENSITY UNI-DIRECTIONAL CARBON FIBRE: Light & super strong with custom orientation to transfer more of your energy into speed than any other fin.
      • DYNAMIC TRAILING EDGE: Internal composite morphs under extreme load, enabling the fins to be pushed harder without sliding out.
