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.

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.
