What is the JAYKAY e-Fin 2.0 really like on the water? The water sports blog Berg & Tal put our electric fin through its paces in a real-world test—both on a SUP and a paddleboat. The focus was primarily on ease of installation, the various riding modes, and the noticeable assistance it provides in headwinds, currents, and on longer trips.

The bottom line: The e-Fin 2.0 provides powerful assistance, is intuitive to use, and offers significantly greater comfort on the water. Especially in challenging conditions, the electric propulsion system can be a real help—without taking away from the actual fun of paddling.
