- 9" single fin shaped for calm, flat water.
- Polyurethane plastic, flexible and hard to snap.
- Fits standard 9" fin boxes.

One fin; screw and plate set sold separately.
A 9in single fin does one job very well: it keeps a paddleboard or longboard tracking straight so you are not switching sides every third stroke. Ours is moulded from tough polyurethane and drops into any standard 9in box, including the one on our SUPs.

Rinse after salt water, keep it out of hot cars and store it in the shade. More in our care guide.

We took a chance on a second-hand Wavestorm Taquito 8-foot children's SUP (which, as I understand, are now discontinued) that had a missing fin. I could have probably saved a couple bucks by buying a knock-off, but we have an adult Wavestorm, and I know their products are quality, so I went for the genuine article. The screw and rectangular nut were included in the shipment, and they fit perfectly. We were up and running in a matter of minutes. I'm extremely happy with this purchase, and with Wavestorm products generally.
