Size
FCS II H4 Smoke Thruster Set – 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.

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 Foil 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 and Specifications
Accelerator: Find Control. Speed, flow and response with added control.
