FCS II H4 Small Tri Fin Set- Fins

   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.

   Side Fins–        Base: 4.36″ / Depth: 4.34″ / Area: 14.29in² / Sweep: 38.3˚

   Center Fin–        Base: 4.29″ / Depth: 4.49″ / Area: 13.82in² / Sweep: 37.2°

   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.

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

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

   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.
