Systems and methods for orienting a marine vessel to minimize pitch or roll
First Claim
1. A system for orienting a marine vessel, comprising:
- a plurality of marine propulsion devices configured to orient a marine vessel;
a control device having a memory and a programmable circuit, the control device configured to control operation of the plurality of marine propulsion devices to maintain orientation of the marine vessel in a selected global position and heading;
wherein the control device is configured to receive pitch and roll of the marine vessel in the global position;
wherein the control device is configured to control operation of the plurality of marine propulsion units to change the heading of the marine vessel to minimize one of the pitch and the roll while maintaining the marine vessel in the selected global position; and
a user input device configured to allow a user to select between at least two different modes of control device operation, including a Pitch Minimization Mode wherein the control device controls operation of the plurality of marine propulsion units to minimize the pitch and a Roll Minimization Mode wherein the control device controls operation of the plurality of marine propulsion units to minimize the roll.

Abstract
Systems and methods for orienting a marine vessel minimize at least one of pitch and roll in a station keeping mode. A control device having a memory and a programmable circuit is programmed to control operation of the plurality of marine propulsion devices to maintain orientation of a marine vessel in a selected global position and heading. The control device receives at least one of actual pitch and actual roll of the marine vessel in the global position and controls operation of the plurality of marine propulsion units to change the heading of the marine vessel to minimize at least one of the actual pitch and the actual roll while maintaining the marine vessel in the selected global position.
