FCS II H4 Tri Fins (SML / PC Carbon / Smoke)

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. Performance Material Size Overview UNIQUE TEMPLATE Radically different side & center 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. Center 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 optimizes flex & regulates the release of energy during rail to rail transitions. Ideal Conditions A wide range of conditions, particularly good 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. Speed, flow and response with added control. NEW CONSTRUCTION Precision Swiss Engineered: Creates perfect synergy between fin geometry & HI-FI materials, giving smooth & predictable feel. High Density Uni-Directional Carbon Fibre: Light & super strong with custom orientation to transfer more of your energy into speed than any other fin. Dynamic Trailing Edge: Internal composite 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.
