Boost Fin Adapters - Find Your Fit
The Boost Fin is designed to be compatible with any surfboard, paddleboard, kayak, and more, thanks to our extensive range of adapters. While there are thousands of different board brands on the market, the fin systems are industry-standard in most cases and we have adapters for the most of them. Even if your board lacks a central fin or has a non-removable one, we have a solution for you.
Note: The Longboard Adapter is included in the package by default.
For those with different fin slot configurations, we offer a wide selection of additional adapters to ensure a perfect fit for your board. No matter what type of watercraft you own, the Boost Fin provides the versatility and performance you need!
