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.

While the science behind the template, the materials and the foils are highly complex, every component of this fin has been engineered to create a simple synergy between the fin and the surfboard, the rider and the wave.

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
