Patent ID: 8131412

Claim:
A method of calibrating a system for controlling thrust and steering of a drive arrangement in a watercraft, the system comprising an operating device adapted for indicating a requested direction of travel of the watercraft, the operating device being connected to a control unit for providing corresponding thrust and steering commands to the drive arrangement, wherein the method comprises the steps of: receiving an activation command in the control unit, for beginning the calibration, detecting any movements of the operating device, storing values corresponding to the movements in the control unit together with corresponding thrust and steering values, and repeating the detecting step and the storing step until a termination command is received in the control unit, thereby using the stored values in subsequent operation of the operating device for indicating the direction of travel of the watercraft, wherein the calibrating is carried out during a docking manoeuvre for the watercraft, and the step of detecting movements of the operating device comprises detecting movements in two perpendicular directions and detecting rotational movements about a longitudinal direction and whereby the operating device comprises a joy-stick arrangement.
