A watercraft includes two steerable propellers driven by motors, the angular positions of and the thrusts produced by the steerable propellers being controlled by a control system. The control system includes an input device having a frame, a head and a handwheel supported on the frame for independent pivotal movement about a common first axis, and a lever supported on the head for pivotal movement about a second axis normal to the first axis. The head, handwheel and lever are each operatively coupled to a respective input element by a respective gear arrangement. A microcomputer responsive to the input elements is connected through several control devices to the motor and the steerable propellers for effecting the requisite control thereof.

A device for controlling the direction of movement and the force in such direction for a watercraft, comprising two thrust generating devices, drive means for driving said thrust generating devices, and an input device which can control rotation of the watercraft about a vertical axis, linear movement of the watercraft in horizontal directions, and the thrust force produced by said thrust generating devices for effecting said rotational and linear movements; wherein said input device includes a first input element for defining the force for linear movement of the watercraft and a second input element for defining the direction of linear movement of the watercraft; wherein said first and second input elements are each controlled by a respective control member; wherein said control member for said second input element is a head which can be pivoted about a stationary first axis and operates said second input element through a first gear arrangement; wherein said control member for said first input element is a lever which is pivotally supported on said head for movement about a second axis which extends at a right angle to said first axis, said lever being operatively connected by a second gear arrangement to a longitudinally movably supported rack which operates said first input element through a pinion; and including a handwheel which is supported for rotation about a third axis and is operatively connected by a third gear arrangement to a third input element.
