Overview

UNIQUE TEMPLATE

Radically different side & centre fin templates create a powerful fin set with ultimate speed & drive.
- SIDE FIN PROFILE: The lower section produces maximum acceleration, while the hatchet like tip creates stability & control.
- CENTRE FIN PROFILE: Highly raked elliptical outline reduces drag, and offers a 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.
