Other rules may apply to local waters. For example, eSurfboards are not allowed on Bavarian lakes and Lake Constance. In Austria the rules are not clear and in Switzerland motorized surfboards are not allowed. You can find out more here.

Aerofoils eFoils have an output of less than 5 kW. The exception are a few waters where the power limit is 5 hp (3.68 kW), such as on parts of the Rhine.
