Abstract
A watercraft and controller are disclosed. An embodiment includes a controller for the water craft being configured to operate at least one drive propeller of the drive system of the watercraft below a first propeller rotational speed according to a first operating state by operating at least one drive motor, connected to the at least one drive propeller, via a first alternating voltage; and operate the at least one drive propeller above the first propeller rotational speed according to a second operating state by operating the at least one drive motor via a second alternating voltage. In a transition from the first into the second operating state or vice versa, the first internal combustion engine is operated at such a rotational speed that the at least one drive propeller is driven at the first propeller rotational speed, and the first alternating voltage is synchronized with the second alternating voltage.
