Adapters to fit the Boost Fin on any board

Yes! Thanks to a variety of adapters that we created, the Boost Fin can fit any surfboard or paddleboard. 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 and you can purchase additional ones in our store.

By default, we provide adapters for these fin systems:

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

Longboard (US fin box)

It's the same US box but you'll need a screw and plate to make sure the adapter stays in place.

Custom

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 Boost Fin and slide-in adapter can be taken off whenever you want.

Stick-On Fin Box

If you are not sure which adapter you need, just take a picture of your fin mount (ideally with a ruler next to it so we can understand the size), send it to [email protected] and we will help you out. This might delay the delivery by a couple of weeks.
