The H4 looks and surfs different to any other fin. Precision Swiss engineering matched with a highly evolved template provides an unprecedented level of control and predictability at high speeds.

 

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 specialised robotic automation combined with camera assisted quality control, ensures absolute accuracy.

Overview

UNIQUE TEMPLATE

Radically different side & centre fin templates create a powerful fin set with ultimate speed & drive.

  • SIDE FIN PROFILE: Lower section produces maximum acceleration, while hatchet like tip creates stability & control.
  • CENTRE FIN PROFILE: Highly raked elliptical outline reduces drag, and offers 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.
