  • Overview

    This set comes equipped with 2 x Quad Rear Fins, designed to work with both medium & large H4 sets.

    UNIQUE TEMPLATE

    While the science behind the template, materials & the foils are highly complex. Every component of this fin has been engineered to create a simple synergy between the fin & the surfboard, the rider & the wave.

    • REAR FIN SYNERGY: The H4 quad combines the power + control of the H4 thruster, with the added speed & drive of a quad.
    • QUAD REAR PROFILE: A similar hybrid outline on the front and rear fins helps minimise turbulence + provides a smooth and predictable feel.
    • ENHANCED FOILS: Revolutionary new foil designed to grip longer through turns and promotes perfect rail to rail 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 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.

    FCS H4

    H4 quads enhanced the performance of my 7'6" HI Mid6. It is now faster with positive projections out of the bottom turn and speed gains on cut backs. They are well worth the extra $$.

    Best fins for SUPs

    The instant off the line speed, quick maneuverability, and drive down the line make this the perfect SUP fin set. Tri fin for slower point breaks when you want fast hits off the lip and stay in the pocket. Quad set for beach breaks and dropping in outside sand bars, the added speed and drive allow you to link up sections and get around crumbling sections with ease. Bottom turns never felt so good. The H4’s have definitely upped my wave game. You know you’re onto something when all the shortboarders sitting inside give you shakas hoots and hollas, when you finish a big set wave.

    Good speed and drive

    I had a H4 thruster set for a while in my 5’11 CI OG Flyer. Bought the H4 quad rears to try in my grovelling board (5’7 CI Ultra Joe) which works better as a quad and usually has AM template fins in it. Using the H4 quad set gives a bit more speed, pushes back a bit harder on a bottom turn and the board definitely holds higher in the wave face. In slow sloppy waves you wouldn’t notice much difference, the AM fins are excellent in that board, but in quick steep waves especially over a couple of feet it is obvious after your first turn.
