Review By Flipping Dust


Propeller pitch, blade surface, and feathering prop are all designed to reduce drag and resistance to a minimum.


At only 2.7 lb (nearly 1200g), you’ll hardly feel it.


Ready for rough seas, your Boost Fin's shock-resistant body is designed to take some hits.

Boost fin inclusions


Important Boost Fin usage recommendations:

  1. Install the propeller cover first, to avoid injury to yourself and others.

  2. Make sure to charge your Boost Fin fully right after you receive it. Charge the battery till it is full at least once a month, even if you don't use the fin.

  3. Always seal the charge port before riding.

  4. Use a board leash in the water, to secure the board to you, to reduce the risk of injury to others.

  5. Fit a Boost Surfing Leash to secure the fin to the board, to avoid losing your Boost fin in the ocean. 

  6. Wash your fin with clean water after every use. Salt and sand left on the fin, will reduce it’s useful life. Learn more here:

  7. Never charge your fin if the charge port is wet. Make sure that the jack is fully dried before charging.
