Abstract
An operating command indicating a requested vessel direction and plotting a course represented by a reference line for the requested vessel direction from an initial position is registered. It is then monitored if the vessel has deviated from the reference line and if a deviation from the reference line is detected, then a value for current vessel speed is detected. The detected vessel speed value is compared to a predetermined reference speed value to determine if the current vessel speed value is within a high speed interval or a low speed interval relative to the reference speed value. Depending on the determined speed interval the vessel is controlled according a low speed control strategy; or a high speed control strategy in order to move the vessel from a current vessel heading to the reference line and the requested vessel direction.
