A retaining device of a water sport device has a drive, which is preferably designed as an electromechanical or electropneumatic drive and via which the foil device can be transitioned from a resting and/or starting position into the operating position and/or from the operating position into the resting and/or starting position. The actuation can take place manually by a person operating the water sport device. The water sport device may already be lowered into knee-deep water near the shore or beach, for example, and guided or driven there in the direction of deeper water. As soon as sufficiently deep water has been reached, the foil device can be transitioned into the operating position, which is at a greater distance from the floating body, by means of the drive. This process can take place automatically when a specifiable or set water depth has been reached or by the release on the part of the person using the water sport device.

A personal watercraft is disclosed including a flotation portion, a strut extending from the flotation portion, and a motor pod is disposed along the strut with an electric motor operably coupled to a driveshaft. A hydrojet unit is removably attached to the motor pod and includes an inlet portion removably attached to the motor pod and a substantially cylindrical housing. The inlet portion includes a substantially conical motor interface with a shaft through-hole for receiving the driveshaft therein, one or more fins extending outwardly from the conical motor interface, and at least one ring encircling the conical motor interface and connecting to each of the one or more fins for inhibiting objects from passing through the inlet region. The housing defines a fluid flow path to an outlet portion. The hydrojet unit includes an impeller coupled to the driveshaft and a stator disposed within the housing.
