PROBLEM TO BE SOLVED: To provide a ship propulsion system and a ship equipped with the same, which can improve the lateral movement performance.SOLUTION: A ship 1 includes two propulsion machines 3L, 3R which are arranged left and right with respect a center line 55 extending in the longitudinal direction through a rotation center 50 of a ship hull 2, respectively, and are variable in propulsion power and steering angle. When an operation device operated by an operator outputs a lateral movement instruction for laterally moving the ship hull 2 in the lateral direction orthogonal to the center line 55, the propulsion machine of the two propulsion machines 3L, 3R, which is arranged on the side of the instructed direction with respect the center line 55, generates backward propelling force, and the propulsion machine of the two propulsion machines 3L, 3R, which is arranged on the side of the opposite direction to the instructed direction with respect the center line 55, generates forward propelling force. Propelling forces TL, TR and steering angles of the two propulsion machines 3L, 3R are controlled so that the acting point of resultant force F of the propelling forces TL, TR of the propulsion machines 3L, 3R lies shifted to the side of the instructed direction with respect the center line 55 and the acting direction of the resultant force F is directed to the instructed direction.

    【課題】横移動性能を向上することができる船舶推進システムおよびそれを備えた船舶を提供する。【解決手段】船舶1は、船体2の回転中心50を通って前後方向に延びる中央線55に対して左側および右側にそれぞれ配置され、推進力および転舵角が可変な2機の推進機3L,3Rを含む。操作者によって操作される操作装置が船体2を中央線55に対して直交する横方向へ横移動させるための横移動指示を出力すると、2機の推進機3L,3Rのうち中央線55に対して指示方向の側に配置される推進機が後進推進力を発生し、2機の推進機3L,3Rのうち中央線55に対して指示方向とは反対方向の側に配置される推進機が前進推進力を発生する。推進機3L,3Rの推進力TL,TRの合力Fの作用点が中央線55に対して指示方向の側にずれて位置し、合力Fの作用方向が指示方向に向くように、2機の推進機3L,3Rの推進力TL,TRおよび転舵角が制御される。【選択図】図6
