FCS - H4 Uni-Directional Carbon - Thruster - Surfboard Fins

UNIQUE TEMPLATES

Radically different side and centre fin templates create a powerful fin set with ultimate speed and drive.

SIDE FIN PROFILE: The lower section provides maximum acceleration, while the scythe-like tip creates stability and control.
CENTRE FIN PROFILE: Highly raked elliptical outline reduces drag and offers a sense of predictability through release off the top.
FOIL TEMPLATE: Thick base with tapered tip optimizes flex and regulates energy release during rail-to-rail transitions.
Ideal Conditions

A wide range of conditions, especially good in critical overhead waves.
