E-fin

Buy an e-fin – electric fin for your SUP & board upgrade with F2

Discover innovative electric fins in our e-fin / e-fin category that equip your SUP, surfboard, kayak, or small watercraft with powerful assistance. The F2 E-Fin is an intelligent propulsion system that detects every paddle stroke and automatically provides a boost – ideal for mastering longer tours or compensating for challenging conditions.

Our e-fins are designed as an all-in-one solution: with an integrated battery and wireless control – no external cables or separate battery units required. This keeps your setup compact and clean. With an output of up to 400 watts, the F2 E-Fin reaches speeds of up to 8 km/h in automatic mode, providing approximately 45 minutes of run time in the highest mode, and up to 1–4 hours in lower modes.

You can purchase the e-fin and mount it to many boards via adapters (US-box, slot-box) – including inflatable SUPs, surfboards, or kayaks. The "manual thrust" mode allows you to adjust the output constantly if you are not paddling or desire a consistent level of assistance.

If you are looking to buy an e-fin, consider mounting compatibility, battery range, power, and control options (e.g., operation on the paddle or by hand). The F2 E-Fin impresses with its simple installation, intelligent assistance, and strong performance on the water.

Your F2 advantage: tested quality, technical innovation, and fast shipping. If you want to take your SUP setup to the next level, you will find your perfect electric fin here – ready for more range, efficiency, and support on your tours.
