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.

Almost intuitive in the way the H4 performs, when you initiate a turn, the fins will work for you by supplying speed when you need it and then releasing at the ideal transition point.

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.

THE FUTURE HAS ARRIVED, SPECIALISED SWISS CONSTRUCTION USING THE LATEST IN ROBOTIC AUTOMATION, ENSURES ABSOLUTE ACCURACY, RESULTING IN A FIN SO FINE-TUNED, NOTHING IS LEFT TO CHANCE.

Radically Different Side & Centre Fin Templates:

Creates a powerful fin set with ultimate speed + drive that doesn’t compromise control or maneuverability

Side Fin Profile:

Lower section produces maximum acceleration while hatchet-like tip creates stability + control

Centre Fin Profile:

Highly raked elliptical outline reduces drag while offering a feeling of predictability when releasing through turns

Fin Foils Profile:

Thicker base with tapered tip optimises flex and regulates the release of energy during rail to rail transitions
