Product Details

Construction

High Density Uni Directional Carbon Fiber– Light & super strong with custom orientation to transfer more of your energy into speed than any other fin.

Precision Swiss Engineered– Creates perfect synergy between fin geometry & HI-FI materials, giving smooth & predictable feel.

Dynamic Trailing Edge– Internal composite morphs under extreme load, enabling the fins to be pushed harder without sliding out.

Features

Side Fins - Flat Foil– A flat inside face combined with a convex outside face. The traditional flat sided foil offers an even combination of drive, pivot, and hold. Provides a very consistent, reliable feel over a wide variety of conditions.

50/50 Foil– A symmetrical foil used on all centre fins where both sides are convex. Even water flow on both sides creates stability and control.

Ideal Conditions– A wide range of conditions, particularly good in critical overhead waves.

Board Types– Recommended for performance shortboards with moderate-to-low rocker.

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.
