Adapters to fit the Boost Fin on any board

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)
  • 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.

If you are not sure which adapter to choose, just send a picture of your fin to [email protected] and we will help you out.
