Boost Fin Adapters Guide | Find Your Fit

The Boost Fin can fit any surfboard or paddleboard, thanks to a variety of adapters that we created. While there are thousands of different board brands, the fin systems are industry-standard in most cases and we have adapters for all of them. The Longboard Adapter is included in the package by default. If you have a different fin slot, we have plenty of additional adapters to fit your surfboard or SUP:

• FCS Longboard
• Slide-in
• FCS 2
• FCS
• Futures
• Futures (Side Fin)
• NSP FCS
• Soft Top
• Flip Lock
• Wayler
• Stick-on Fin Box

Stick-On Fin Box

Some brands make their own fin box that is only compatible with those brands fins. These fins have very few if any fin options. In case you have a brand-specific fin box, non-removable fins, twin fin setup, or no fin slot at all – we provide a universal stick-on mount. It’s also a perfect solution for kayaks or other water toys. The fin box adapter is designed to attach to any surface with a water-resistant adhesive. Once you have the fin box attached, the adapter simply plugs into the fin box. The fin box becomes a permanent part of your board, but the Boost Fin and slide-in adapter can be taken off whenever you want.
