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.
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.
A quick note about our photos!
We use a mix of official brand images and real-life shots from our warehouse to help you make an informed decision.
That said, what you see might differ slightly from what you receive — simply because we can't photograph every possible variation.
For example, a photo might show a 6'2 board with Futures fin boxes, while you've selected a 5'10 with FCS II. Don’t worry — you’ll get exactly what you ordered.
Sometimes, small details like the logo, its placement or overall colour tones can vary slightly depending on the production batch, camera, lighting, or even your screen settings.
These are always only minor differences, and in most cases, the photos are spot on - but we totally get that buying online can feel tricky. If you ever want more details, just drop us a message — we're happy to help!
