Abstract
Systems and methods are for maneuvering a marine vessel having a plurality of steerable propulsion devices. The plurality of propulsion devices are controlled to achieve a lateral movement by controlling the steering orientation of port and starboard propulsion devices so that forward thrusts provided by the port and starboard propulsion devices intersect at or forwardly of a center of turn of the marine vessel. One of the port and starboard propulsion devices is operated to provide a forward thrust and the other of the port and starboard propulsion devices is operated to provide a reverse thrust so that the lateral movement is achieved and a resultant yaw component is applied on the marine vessel. An intermediate propulsion device is controlled to apply an opposing yaw component on the marine vessel that counteracts the resultant yaw component.
