Unbreakable 5.5 Keel Fin for Touring or Racing SUP Paddleboards or Longboards

Findestructable Tech: The proprietary polymer used in Findestructable fins provides rigidity against the water for unparalleled performance, yet it flexes when under pressure out of the water to keep the fin box from breaking. Fiberglass fins or carbon fins can chip, crack, or shatter when scraping the bottom, but Findestructable fins take the hit without so much as a dent. These fins offer the perfect balance between performance and peace of mind.

The Keel Fin Shape is the fastest fin shape for flat water paddling. Its low-profile 6.5-inch height and rake fin shape create less leading edge drag in the water when SUP Touring or paddleboard racing. The long base line gives massive amounts of side-to-side stability and will increase board stability by 30% when replacing a traditional dolphin nose fin. The specifications of this fin include a depth of 5.5 inches, a base of 6 inches, and a rake of 45 degrees.

This fin is compatible with any SUP or surfboard with a standard 8.5-inch or 10.5-inch fin box. However, there are known incompatibilities with some Inflatable SUPs, such as the Bali Solstice and AquaMarine SPK2.

To make installation easy, we include a "No Tool" fin screw and plate set, allowing you to install the fin on your board right away without the need for any tools.

In summary, the Findestructable Tech fins offer exceptional performance and durability, while the Keel Fin Shape provides superior stability and speed for flat water paddling. The easy-to-install design and compatibility with a wide range of boards make these fins a great choice for SUP enthusiasts.
