The H4 offers unprecedented control and predictability at high speeds due to its unique design and precision Swiss engineering.

Overview of The H4 Fin

  • The H4 is distinctively designed, looking and surfing different than any other fin, providing ultimate speed & drive.
  • Radically different side & centre fin templates empower the surfer with increased acceleration and stability.
  • Its side fin profile's lower section produces maximum acceleration, while the hatchet-like tip offers stability & control.
  • The centre fin's raked elliptical outline reduces drag and offers a predictable feeling when releasing through turns.
  • Thicker base with tapered tip optimizes flex and regulates the release of energy during transitions.

Ideal Conditions

  • A wide range of conditions but particularly shines 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. Emphasizes speed, flow, and response with added control.

New Construction

  • PRECISION SWISS ENGINEERED: Ensures a perfect synergy between fin geometry & high-quality materials, giving a smooth and predictable feel.
  • HIGH DENSITY UNI-DIRECTIONAL CARBON FIBRE: Light & robust, transferring more of your energy into speed than any other fin.
  • DYNAMIC TRAILING EDGE: 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.


MEDIUM: Suitable for those weighing 65Kg - 80Kg (145 - 175 Lbs).
