Systems and methods for maneuvering a marine vessel
View Patent ↗Systems for maneuvering a marine vessel comprise a plurality of marine propulsion devices that are movable between an aligned position to achieve of movement of the marine vessel in a longitudinal direction and/or rotation of the marine vessel with respect to the longitudinal direction and an unaligned position to achieve transverse movement of the marine vessel with respect to the longitudinal direction. A controller has a programmable circuit and controls the plurality of marine propulsion devices to move into the unaligned position when a transverse movement of the marine vessel is requested and to thereafter remain in the unaligned position after the transverse movement is achieved. Methods of maneuvering a marine vessel comprise requesting transverse movement of the marine vessel with respect to a longitudinal direction and operating a controller to orient a plurality of marine propulsion devices into an unaligned position to achieve the transverse movement, wherein the plurality of marine propulsion devices remain in the unaligned position after the transverse movement is achieved.
1. A system for maneuvering a marine vessel, the system comprising:
an input device for requesting at least a transverse movement of the marine vessel with respect to a longitudinal direction;
a plurality of marine propulsion devices that are movable between at least an aligned position wherein the plurality of marine propulsion devices define thrust vectors that are parallel to each other and an unaligned position wherein the plurality of marine propulsion devices define thrust vectors that are not parallel to each other;
a controller that has a programmable circuit and that controls movement of the plurality of marine propulsion devices between the aligned and unaligned positions;
wherein upon operation of the input device to request transverse movement of the marine vessel the plurality of marine propulsion devices are moved into the unaligned position to achieve said transverse movement and thereafter remain in the unaligned position until further movement of the marine vessel is requested; and
a shift lever for requesting a change in shift of at least one of the plurality of marine propulsion devices, wherein the controller controls movement of the plurality of marine propulsion devices into the aligned position upon operation of the shift lever, and to thereafter remain in the aligned position.
2. A method of maneuvering as marine vessel, the method comprising:
requesting transverse movement of the marine vessel with respect to a longitudinal direction and operating a controller to orient a plurality of marine propulsion devices into an unaligned position wherein the plurality of marine propulsion devices define thrust vectors that are not parallel to each other to thereby achieve the transverse movement, wherein the plurality of marine propulsion devices remain in the unaligned position after the transverse movement is achieved and until further movement of the marine vessel is requested; and
operating the controller to align the plurality of marine propulsion devices in the longitudinal direction wherein the plurality of marine propulsion devices define thrust vectors that are parallel to each other when a shift lever is operated to request a change in shift of at least one of the plurality of marine propulsion devices.
