  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.
  • INNOVATIVE PRODUCTION: Highly specialised robotic automation combined with camera-assisted quality control, ensures absolute accuracy.
