Abstract:
A method for maneuvering a marine vessel, comprising the steps of:providing a first marine propulsion unit which is attachable to a transom of said marine vessel;providing a second marine propulsion unit which is attachable to said transom of said marine vessel;receiving a maneuver command from a manually controllable device;calculating a first magnitude of thrust for said first marine propulsion unit as a function of said maneuver command; andcalculating a second magnitude of thrust for said second marine propulsion unit as a function of said maneuver command, said first and second magnitudes of thrust being calculated to create a resultant force vector imposed on said marine vessel and a resultant moment about an instantaneous center of turn of said marine vessel which will achieve said maneuver command, said first and second magnitudes of thrust being unequal to each other in order to create a magnitude of said resultant moment about said instantaneous center of turn which is unequal to zero.
