Unibox system – a different fin concept

The patented Unibox system removes the limitations of traditional fin profile design. The fin is fixed by its heel into a box placed on the upper part of the board, allowing the screw to remain outside the fin’s thickness. This design keeps the fin profile thin and reduces drag in the water.

Flex and board behavior

The fin and box work together in a sandwich construction, allowing the board to retain a reduced thickness and its natural flex. The unique flex of Unibox fins makes the board feel smoother while riding and more forgiving on landings, with less tendency to stall and more progressive edge engagement.

Glide and planing performance

Thanks to the thin, asymmetrical profile, Unibox fins improve glide and help the board reach planing speed more easily. Reduced drag results in smoother acceleration and increased comfort while riding.

Choosing the height – 35 mm vs 50 mm

  • 35 mm – lower-profile fins focused on minimal drag and improved glide, ideal for freestyle riders looking for more speed
  • 50 mm – taller fins offering increased control and stability, well suited for stronger edge hold and more versatile riding

Additional details

A notch in the box allows the attachment of a board leash, adding practical functionality to the setup.
