Description of the model

Meet the Boost Fin Plus

The Boost Fin Plus is our newest model, created to make your time on the water smoother and easier. It now comes with a folding propeller that reduces drag and helps prevent seaweed from getting stuck, so you can enjoy a cleaner and more comfortable ride. The fin is also built with stronger materials and an improved power system, giving you up to 15% more battery life.

Whether you’re surfing or using a SUP, the Boost Fin Plus helps you move with less effort. It can assist you with catching waves, getting back to the lineup, cruising on flat water, or dealing with wind and currents. You can adjust all modes directly in the app.

Why choose the Boost Fin Plus?

• A first in the industry

Folding propellers in board fins are a brand-new innovation, and we’re proud to be the first to introduce it.

• Less drag

The new design noticeably reduces drag, especially on smaller boards (7–8 ft). You can expect around 20% improvement when switching to the Plus model.

• Folding propeller

The folding blades help prevent seaweed from blocking the motor. They usually clean themselves after a few on/off cycles, so you spend less time dealing with jams.

• Lower resistance when the motor is off

When the blades fold, the fin creates less resistance in the water, making it easier to paddle or glide naturally.

• Adjustable thrust

You can remove one blade to reduce thrust by about 10–15%. This also increases battery life by the same amount and gives you smoother, more balanced power, with only a small decrease in maximum output.

• Stronger design

The Boost Fin Plus comes with a new coating that helps protect it from scratches and small impacts—useful when surfing near rocks or sand.
