ABSTRACT:
Boat with a hull with double engines which are controlled by a respective electronic engine control unit and are coupled to a respective outboard drive, which drives are driven by electric servomotors/electronic drive control units. The drive control units communicate with the engine control units and continuously monitor the steering function of the drives and together with the engine control units, upon detection of a steering fault in a control system, gradually to reduce the speed of the engine in question to idling, to activate an alarm, to reduce the throttle of the other engine, to disengage and lock in neutral position the gear of the failing drive, and to lock the drive in the current angular position. After acknowledgement from the driver, neutral lock is cancelled and a gear can be engaged. The associated engine can then be used with but limited to approximately half throttle.
