Ship maneuvering device

摘要

Provided is a ship maneuvering device that can increase operation sensitivity and enables smooth operation when simultaneously operating the rotation component determination unit and the oblique sailing component determination unit of an operation means. In the ship maneuvering device 1, a control device 31 computes a rotation component propulsion vector Trot for rotation and an oblique sailing component propulsion vector Ttrans for oblique sailing for left and right out-drive units 10A, 10B from the amount of operation of a joystick 21, calculates the combined torque T by combining the rotation component propulsion vector Trot and the oblique sailing component propulsion vector Ttrans for each of the left and right out-drive units 10A, 10B, and computes the propulsion and orientation for each of the left and right out-drive units 10A, 10B.
