FCS H4 surf fins look and behave differently compared to other fins. Swiss engineering precision combined with a highly evolved model provides an unprecedented level of control and predictability at high speed.

Radically different side and center fin designs create a powerful fin set with optimal speed and ride

SIDE FIN PROFILE: The lower section produces maximum acceleration, while the hatchet-shaped tip provides stability and control.

CENTRAL FIN PROFILE: The steeply angled elliptical profile reduces drag and provides a feeling of predictability when relaunching through turns.

A thicker base with a tapered tip maximizes flexibility and regulates the release of energy during transitions between rails.

These fins cover a wide range of conditions and perform particularly well in solid conditions.


  • 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.
