Abstract: A control device for an outboard motor controls a plurality of outboard motors included in a ship. Each outboard motor includes a propulsion unit and a steering actuator. The ship includes an operation unit that operates the steering actuator and the propulsion unit. The operation unit can be positioned at a first position at which the outboard motors do not generate a propulsion force for the ship, a second position at which the outboard motors generate a propulsion force for moving the ship in a leftward-rightward direction, and a third position at which the outboard motors generate a propulsion force for moving the ship in an oblique direction that forms an acute angle with the leftward-rightward direction. A forward-backward direction component of a propulsion force in the oblique direction which is generated by the outboard motors.

Abstract: A marine vessel includes: an actuator having a rudder; a heading detection unit; and a heading control device including a target heading acquisition unit, a heading deviation calculation unit, a PID control unit, and a gain setting unit, the heading deviation calculation unit calculates a heading deviation, which is the difference between a target heading and a actual heading, the PID control unit calculates an instruction value for the actuator through PID control from the heading deviation calculated by the heading deviation calculation unit, the gain setting unit sets at least a derivative gain, and in a case in which the heading deviation calculated by the heading deviation calculation unit is equal to or greater than a first threshold value, the gain setting unit adds a derivative gain addition correction quantity to the current value of the derivative gain.

Abstract: A ship propulsion device controller controls a plurality of ship propulsion devices disposed on a rear portion of a hull of a ship. The ship includes an operation unit configured to operate the ship propulsion devices. The operation unit is able to be positioned at a first position where the ship propulsion devices do not generate propulsion forces for the ship and a second position where the ship propulsion devices generate propulsion forces for moving the ship in a right direction, a right-forward direction, or a right-backward direction or a third position where the ship propulsion devices generate a propulsion force for moving the ship in a left direction, a left-forward direction, or a left-backward direction.

Abstract: This outboard motor control device controls a plurality of outboard motors disposed on a rear portion of a hull of a boat. Each of the outboard motors includes a propulsion unit and a steering actuator. A boat includes an operation unit configured to operate the steering actuator and the propulsion unit. The operation unit is able to be positioned at a first position where the outboard motors do not generate a propulsion force of the boat and a second position where the outboard motors generate a propulsion force for moving the boat in a left-right direction. When the operation unit is moved from the first position to the second position and maintained at the second position, the outboard motors generate a first propulsion force during a first period from a first timing when the operation unit is moved to the second position to a second timing and subsequently generate a second propulsion force greater than the first propulsion force during a second period after the second timing.
