Abstract
The invention relates to a motorized watercraft with a control device () and with a drive unit () having a water propeller that is driven by an electric motor (). The electric motor (), an operating unit (), a motor controller (), a battery controller () and a battery () are placed in a vehicle hull, and the water propeller is mounted in a flow channel in the vehicle hull. In order to connect the controlling components and the components to be controlled by means of a system architecture, a system bus and of a man-machine interface, the invention provides that the operating unit (), the motor controller (), and the battery controller () are data-connected by means of a communications device controlled by the control device (). This enables an, in particular, fail-safe transmission of data, a constant monitoring of the system components, and when required, an emergency shut-down.
