• Choose this fin for: flowing turns, steady trim and a balance of drive and manoeuvrability.

• Board suitability: longboards and suitable mid-length single-fin boards where a 9″ center fin matches the board design, rider and conditions.

• How it is designed to feel: the broad base supports drive and hold, while the swept-back outline encourages smooth, arcing turns.

• Noseriding or carving? An all-round option for combining turns with occasional nose time. Noseriding hold also depends on the board, wave and fin position.

• Check your fitting: designed for a sliding center fin box. Confirm your board’s box and required fin size before ordering.

• Included: one fin, with a fin screw and plate.
