• 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 minimize 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.
  • Innovative Production: Highly specialized robotic automation combined with camera assisted quality control, ensures absolute accuracy.
