The JayKay fin is exactly what I was looking for. Easy and quick to install, robust and high-performance in use, and the ultimate gadget for electric fun on the water.
The extended range enables a completely new experience and independence on longer tours. At sea, the fin gives you plenty of power to get through the waves. In short, it's just great. I'm already looking forward to the new version 2.0. Battery replacement "on the fly" sounds like even more speed and range. JayKay, keep up the good work!
