FCS II H4 Uni-Directional Carbon Quad Rear Fins

This set consists of 2 x quad rear fins, designed to work with both the medium and large H4 sets.

Unique Template

The science behind the template, materials, and foils is incredibly complex. Every component of this fin has been developed to create a simple synergy between the fin and the surfboard, and between the rider and the wave.

• Synergy in the rear fins: The H4 quad combines the power and control of the H4 thruster with the added speed and drive of a quad.
• Quad rear profile: A similar hybrid outline on the front and rear fins limits turbulence and ensures a smooth and predictable feel.
• Improved foils: A revolutionary new foil that maintains grip longer through the turn and encourages perfect rail-to-rail transitions.

Ideal Conditions

• A wide range of conditions, and particularly good in critical overhead waves.

Board Types

• Designed for the FCS II Fin System.
• Recommended for performance shortboards with medium to low rocker.

Fin Family

• Accelerator: Find Control. Speed, flow, and response with added control.

New Construction

• Precision Swiss engineering: Ensures perfect synergy between the fin geometry and the HI-FI materials, providing a smooth and predictable feel.
• High-density uni-directional carbon: Light and super strong, with a proprietary fiber orientation that converts more of your energy into speed than any other fin.
• Dynamic trailing edge: The internal composite deforms under extreme load, allowing you to push the fins harder without spinning out.
• Innovative production: Highly specialized robotics combined with camera-guided quality control guarantees absolute accuracy.
