Frequently Asked Questions

Are these fins compatible with all SUPs?
They fit most standard SUP fin systems (US Box / Slide-in) as used in many Starboard boards.

Why is the weight important?
At only 48 g per fin, they reduce overall drag and improve acceleration, giving elite paddlers a competitive edge.

How does Prepreg Carbon differ from standard materials?
Prepreg Carbon is pre-impregnated with resin under heat and pressure, delivering a more consistent, lighter, and stronger fin compared to hand-laminated carbon.
