Abstract: A method of controlling attitude of a marine vessel includes measuring a roll motion of the marine vessel with an attitude sensor, and then determining that the roll motion exceeds a threshold roll where no corresponding steering input is present. The method further includes determining a counteracting drive movement for at least one propulsion device based on the measured roll motion and then controlling a steering actuator to move the at least one propulsion device to effectuate the counteracting drive movement so as to counteract an environmentally-induced roll motion of the marine vessel without effectuating a net change in heading and/or translation.

Abstract: A controller for a watercraft controls first and second marine propulsion devices to start moving the watercraft by setting a first default angle, a second default angle, and a default thrust ratio as a first target rudder angle, a second target rudder angle, and a target thrust ratio respectively when a desired motion of the watercraft is straight sideways movement. The controller determines at least one of a first correcting angle, a second correcting angle, and a correcting thrust ratio to reduce an error between the straight sideways movement of the watercraft and an actual motion of the watercraft. The controller corrects the first target rudder angle, the second target rudder angle, and the target thrust ratio with the first correcting angle, the second correcting angle, and the correcting thrust ratio, respectively. The controller repeatedly detects the error and repeatedly updates the correcting angles and the correcting thrust ratio.

Abstract: A marine propulsion system includes a controller configured or programmed to perform a marine vessel traveling direction control such that a traveling direction of a marine vessel is changed to a predetermined angle equal to or greater than a first angle with respect to a traveling direction of waves toward the marine vessel when the traveling direction of the marine vessel is less than the first angle with respect to the traveling direction of the waves toward the marine vessel.

Abstract: Aspects of the invention may be related to a computer system and a computerized method of controlling a marine vessel. Embodiments may include: receiving, by a controller, a position of the marine vessel from a positioning system; receiving, by the controller, geographical data, from at least one database, the geographical data may include at least a map of seabed depths; receiving, by the controller, a heading direction and speed of the marine vessel; calculating, by the controller, a safety zone ahead of the marine vessel based on the position, the heading direction and the speed of the marine vessel; identifying a location of a critical seabed depth inside the safety zone based on the received, the geographical data; and changing, by the controller, a state of a propelling unit of the marine vessel when a critical seabed depth was identified inside the safety zone.

Abstract: An apparatus and method for use with a marine vessel having a first steerable propeller and a second steerable propeller is disclosed. The apparatus and method providing for movement of the first and second steerable propellers relative to each other and also maintains a minimum distance between the first and second steerable propellers so as to prevent the first and second steerable from contacting each other. Also disclosed is a control system and method to control the first steerable propeller and the second steerable propeller to provide the fixed distance between the first and second steerable propellers and so as to individually control the first steerable propeller and the second steerable propellers to allow the first steerable propeller and the second steerable propeller to move relative to each other.

Abstract: A watercraft propulsion system includes a bow thruster, at least two propulsion devices, a translation operator to command a hull translation movement, and a controller configured or programmed to, in a translation watercraft maneuvering mode, control the propulsion devices so that propulsive force action lines thereof cross each other in the hull, and to drive one of the propulsion devices forward and drive another of the propulsion device in reverse. In a standby state, the controller is configured or programmed to prevent the bow thruster and the propulsion devices from generating propulsive forces, and set the steering angles of the propulsion devices to translation standby steering angles. In response to the operation of the translation operator, the controller is configured or programmed to cause the bow thruster and the propulsion devices to start generating the propulsive forces, and change the steering angles of the propulsion devices to translation steering angles.
