Abstract:
1. A ship maneuvering device comprising: a pair of left and right engines; rotation speed changing actuators independently changing engine rotation speeds of the pair of left and right engines; a pair of left and right outdrive devices respectively connected to the pair of left and right engines and rotating screw propellers so as to propel a hull; forward/reverse switching clutches disposed between the engines and the screw propellers; a pair of left and right steering actuators respectively independently rotating the pair of left and right outdrive devices laterally within a predetermined angle range; an operation device setting a traveling direction of a ship; an operation amount detection device detecting the operation amount of the operation device; and a control device controlling the rotation speed changing actuators, the forward/reverse switching clutches, and the steering actuators so as to travel to a direction set by the operation device, wherein the control device calculates oblique sailing component propulsion power vectors for oblique sailing of the left and right outdrive devices and turning component propulsion power vectors for the turning from the operation amount of the operation device, and composes the oblique sailing component propulsion power vectors and the turning component propulsion power vectors of the left and right outdrive devices so as to calculate composition vectors, thereby calculating propulsion powers and directions of the left and right outdrive devices, wherein when the direction of the composition vector is over a predetermined angle range of the outdrive device, the outdrive device is controlled so as to be made a predetermined limiting angle mode and the engine rotation speed is reduced to a set rotation speed.
