The H4 looks and surfs differently to any other fin. Precision Swiss engineering matched with a highly evolved template provides an unprecedented level of control and predictability at high speeds.

Quad Rears are designed to work with both medium & large H4 sets.

Overview

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 & the 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.

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 a 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.
