    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. When the operation unit is moved from the first position to the second position and maintained at the second position, the ship propulsion devices generate a clockwise rotating moment in the ship during a first period from a first timing when the operation unit is moved to the second position to a second timing and do not to generate the clockwise rotating moment in the ship during a second period after the second timing.

    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 in a case in which the operation unit is moved from the first position to the third position via the second position is larger than that in a case in which the operation unit is moved directly from the first position to the third position, or a leftward-rightward direction component of a propulsion force in the oblique direction which is generated by the outboard motors in the former case is smaller than that in the latter case.

    Abstract: This automatic setting device for automatically setting control devices for a plurality of ship propulsion apparatuses for generating ship propulsion forces is provided with: an input operation setting unit that sets an input operation for a ship; a target behavior acquisition unit that acquires a target behavior of the ship corresponding to the input operation set by the input operation setting unit; a ship information acquisition unit that acquires ship information about the position and/or the bearing of the ship; an actual behavior calculation unit that calculates the actual behavior of the ship on the basis of the ship information acquired by the ship information acquisition unit; and a propulsion force setting unit that sets the magnitudes and the directions of the propulsion forces generated by the respective ship propulsion apparatuses on the basis of the actual behavior of the ship acquired by the actual behavior calculation unit and the target behavior of the ship acquired by the target behavior acquisition unit.

    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.
