FCS 2 H4 Precision Made Thruster Surfboard Fins  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 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 specialised robotic automation combined with camera assisted quality control, ensures absolute accuracy.  MEDIUM (65Kg - 80Kg / 145 - 175 Lbs)LARGE (75Kg - 90Kg / 165 - 200 Lbs)
