FCS II H4 Quad Rear Fins look and surf 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.

This set comes equipped with 2 x Quad Rear Fins, designed to work with both medium & large H4 sets.

Unique Template

While the science behind the template, materials & foils are highly complex. Every component of this fin has been engineered to create a simple synergy between the fin & the surfboard, the rider & the wave.

• REAR FIN SYNERGY: The H4 quad rear combines the power control of the H4 thruster, with the added speed & drive of a quad.
• QUAD REAR PROFILE: A similar hybrid outline on the front and rear fins helps minimise turbulence provides a smooth and predictable feel.
• ENHANCED FOILS: Revolutionary new foil designed to grip longer through turns and promotes perfect rail to rail 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.
