Abstract (en)
[origin: WO2020257832A1] The invention relates to a water ski (1) having: a ski body (2) which can float and is assigned, in addition to a binding (3), a propulsion drive comprising a rotary drive unit with a rotary drive (4) and a screw drive that can be driven therewith; and a control device (6) for specifying a drive power. In order to create advantageous drive conditions, according to the invention the water skis (1) of a water ski pair each comprise a rotary drive unit with at least one drive sensor (7), an assigned stored energy source and a communications device, which synchronises the rotary drives (4) of the two water skis (1) on the basis of drive sensor data and specification data of the control device (6).
