More thrust on the SUP thanks to the e-fin

The e-fin from F2 works very similarly to an e-bike and provides additional thrust whenever you apply power while paddling yourself. Then a small motor whirs and ensures that it goes forward with momentum. I've often heard of drive systems for SUP, but I've never used one or seen one in action. That's why, at the OutDoor by ISPO sports trade show, I stop in front of the small aquarium set up at the brand's booth. In it a turquoise fin with benefits. That is, it has a small propeller, if you can call it that at this size. In front of it a paddle with controller, rotary and slider. Since I make the aquarium spill over directly in the first attempt, I let me briefly show how the system works.

As far as the handling of the system is concerned, everything is quickly clear: The controller on the paddle registers the movement and controls the motor accordingly. If you swing it, it gives thrust. In addition, the e-fin has a continuous mode that propells your SUP, surfboard or light boat forward at 400 watts. Without paddling, 45 minutes at 8 mph should be possible.

Relatively foolproof, provided the fin is used on the water rather than in a small aquarium. The Turbo part can be mounted on boards with US Box fin box (the one with the screw) and slot box (the attachment with the plastic clip). Without disturbing cables, it is overall very inconspicuous, but not everywhere welcome.

When asked if it is legal to use, the answer is: depends on where. I learn at the booth of the Bavarian manufacturer that the E-fin is no problem on many German waters. Similarly, it is written at stand-up-paddling.org. But the rules are not the same everywhere. On Lake Constance, for example, it is already problematic on the German side due to the local navigation regulations. And in Switzerland, the motor on the SUP collides head-on with the inland navigation ordinance. This states that, among other things, paddle boats, racing rowboats, sailboards and dragon sailboards, as well as inflatable and similar pleasure and bathing devices may not be equipped with a motor.

However, e-propulsion is a logical development in the world and also on the water, which does not stop at recreational athletes. Who knows, maybe one day the rules will be adapted to the trend. It enables joint tours at different fitness levels, extra power in headwinds or simply a bit more comfort. A small motor can also serve well as a boosting aid when "winging" (with a paraglider as in the picture above). Purists will grumble about what they see as superfluous motorization. Others rejoice in new possibilities that will certainly be seen more often on lakes in the coming years. Which side are you on?
