FCS II H4 Smoke Tri Fins
FCS II H4 Fin Thruster Set
The FCS II H4 is a surfboard fin that looks and surfs differently to any other fin. Constructed using precision Swiss engineering combined with a highly evolved template provides unprecedented levels of predictability and control through manoeuvres and at high speeds.

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.
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.
