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.
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.

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 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.
