  • 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.

    H4s hit sections other fins can’t reach

    VW Golf or Toyota Yaris? That’s the difference in speed, handling and cost for my H4s compared to my trusty KA Mediums….

    I’ve gone back to KA time and time again after dabbling with MF, JW, PC and Neo Glass Performers and JS but these H4 Small are next level Joy of Surfing!

    Smooth like a knife through butter, fast and drivey like a turbo under your feet and so easy to turn, you kinda don’t even contemplate your line being disrupted by a wiggle, a rail bog, catch or feeeling your toes crushing your deck as you try to keep up enough pressure!

    Get them, they’re worth it.
