Abstract
The invention relates to water ski (1) having a buoyant ski body (2), to which, in addition to a binding (3), a propelling drive is assigned, which comprises a rotary drive unit with a rotary drive (4) and a screw drive which can be driven thereby, and having a control device (6) for presetting a drive power. In order to create advantageous drive conditions, it is proposed that the water skis (1) of a pair of water skis each comprise a rotary drive unit with at least one drive sensor (7) each, an associated energy storage device and a communication device, which adjusts the rotary drives (4) of both water skis (1) as a function of drive sensor data and preset data of the control device (6).
Claims16
A water ski comprising:
- a buoyant ski body having a binding and a propelling drive associated therewith;
- wherein said propelling drive comprises a rotary drive unit with a rotary drive and a screw drive driven thereby, said propelling drive further having a control device presetting a drive power;
- wherein the water ski is configured so that the water ski can be combined with another water ski that has a respective rotary drive and a respective control device so as to form a pair of water skis;
- and
- wherein the rotary drive unit of each of said water skis has at least one drive sensor, an associated energy storage device, and a communication device adjusting the respective rotary drive of both of said water skis based on drive sensor data and preset data of the respective control device.
A water ski system, comprising:
- a pair of water skis each including a respective buoyant ski body having a binding for a foot of a user, and a propelling drive supported on the ski body;
- said propelling drives each including a respective rotary drive unit with a rotary drive driving a screw drive, and said propelling drives each having a respective control device associated therewith controlling a drive power thereof;
- and
- wherein the rotary drive units have respective drive sensors, respective energy storage devices, and respective communication devices adjusting operation of the respective rotary drive of both of said water skis based on data of the drive sensor and stored preset data via the respective control device.
