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. This set comes equipped with 2 x Quad Rear Fins, designed to work with both Medium & Large H4 sets. While the science behind the template, materials & the foils are highly complex. Every component of this fin has been engineered to create a simple synergy between the fin & the surfboard, the rider & the wave.

The H4 quad combines the power + control of the H4 thruster, with the added speed & drive of a quad. A similar hybrid outline on the front and rear fins helps minimize turbulence + provides a smooth and predictable feel. Revolutionary new foil designed to grip longer through turns and promotes perfect rail to rail transitions. Creates perfect synergy between fin geometry & HI-FI materials, giving smooth & predictable feel. Light & super strong with custom orientation to transfer more of your energy into speed than any other fin. Internal composite morphs under extreme load, enabling the fins to be pushed harder without sliding out. Highly specialized robotic automation combined with camera assisted quality control, ensures absolute accuracy.
