FCS II H4 Tri · Smoke · Various Sizes

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.

Overview

• 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 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.

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.
