FCS H4 Large Thruster Fins
The H4 looks and surf different to any other fin. Precision Swiss engineering matched with a highly evolved template provides an unprecedented level of control and predictability at hight speeds. Al most 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.
Radically different side and centre fin templates creates a powerful fin set with ultimate speed and drive that doesn't compromise control or maneuverability.
SIDE FIN PROFILE
Lower section produces maximum acceleration while hatchet-like tip creates stability and 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.
