The Surf Fin That Thinks Like a Motor

For surfers and paddleboarders, paddling out and catching waves can be physically demanding, especially in strong currents or crowded lineups.

The Boost Fin, an electric-powered surf fin from Boost Surfing, offers a new solution. It’s a compact, mountable motor designed to attach to most boards and deliver an extra push when needed, making paddling faster, takeoffs easier, and fatigue far less of a barrier.

How It Works

The Boost Fin provides up to 20 pounds of thrust, delivering short bursts or sustained power through a wrist-mounted remote. Whether you're struggling to get past the break, chasing down a wave, or simply cruising, the fin gives your strokes added force.

It’s compatible with a wide range of surfboards and stand-up paddleboards (SUPs), installs in minutes, and is light enough not to disrupt your ride dynamics. Waterproof and shock-resistant, it’s built for repeated use in open water and can be controlled easily even in rough conditions.

Key Features

• High Thrust Output: Up to 10 mph top speed, ideal for breaking through surf or catching waves more easily.

• Compact & Lightweight: Weighs just 2.7 lbs, maintaining board responsiveness.

• Universal Mounting: Includes adapters for FCS, Futures, and US Box fin systems.

• Wrist Remote: Start, stop, or toggle between power modes while paddling.

• Waterproof & Rugged: Built to IPX8 standards for full submersion.

Who It’s For

• Beginners needing extra confidence catching waves.

• Older surfers or those with limited strength looking to stay active longer.

• SUP riders tackling headwinds, distance paddles, or ocean currents.

• Recovery-focused athletes easing back into water sports with support.

While the battery isn’t designed for continuous use over long distances, the fin excels at providing quick bursts of power exactly when it counts—giving users more energy for longer sessions and better positioning.
