A surfboard powered by an electric motor that you control with a wireless remote. Above a certain speed it lifts and flies on a foil, an underwater wing.
Most of our students stand up within minutes. As soon as you take off, everything goes silent: you can fly at 10 to 40 km/h, although beginners always fly at minimum speed on large, stable wings.
Always with an instructor, life jacket, helmet and a support boat. You get a briefing on land before going into the water.
