- H4 Uni-Directional Carbon - Thruster - Surfboard Fins

UNIQUE TEMPLATES

Radically different side and centre fin templates create a powerful fin set offering ultimate speed and propulsion.

SIDE FIN PROFILE: The lower section ensures maximum acceleration, whilst the wing-like tip provides stability and control.
CENTRAL FIN PROFILE: A sharply angled elliptical outline reduces drag and offers a sense of predictability when releasing during turns.
FIN FOIL TEMPLATE: A thick base with a tapered tip optimises flexibility and regulates energy transfer during 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: Fin Control. Speed, flow and responsiveness with added control.


NEW CONSTRUCTION

PRECISION SWISS ENGINEERING: Creates perfect synergy between fin shape and HI-FI materials, resulting in a smooth and predictable feel.
HIGH-QUALITY UNI-DIRECTIONAL CARBON FIBRE: Lightweight and super-strong, with a customised orientation to convert more of your energy into speed than any other fin.
DYNAMIC REAR EDGE: The internal composition changes under extreme stress, allowing the fins to be pushed harder without slipping.
INNOVATIVE MANUFACTURING: Highly specialised robotic automation combined with camera-assisted quality control ensures absolute precision.
