PROBLEM TO BE SOLVED: To provide a water jet propulsion assist type propeller propulsion ship allowing reduction of a rear width of a hull while securing sufficient propulsion power.SOLUTION: A water jet propulsion assist type propeller propulsion ship includes: a hull 2; a pair of screw propeller propulsion devices 4 having propeller shafts 18 extending in the longitudinal direction of the hull 2 and screw propellers 19 mounted at rear ends of the propeller shafts 18; and a plurality of water jet propulsion devices 3 having water introduction ports 11 which are opened at the ship bottom of the hull 2 so as to introduce water from the outside of the hull 2 and impellers 14 for jetting the introduced water. The plurality of water jet propulsion devices 3 are arranged between a pair of screw propellers 19 in the horizontal direction of the hull 2.

    【課題】十分な推進力を確保しつつ、船体の後方幅を小さくすることができるウォータージェット推進アシスト型プロペラ推進船。【解決手段】船体2と、船体2の前後方向に延在するプロペラシャフト18と、プロペラシャフト18の後端に取り付けられたスクリュープロペラ19と、を有する一対のスクリュープロペラ推進装置4と、船体2の船底に開口し船体外部から水を導入する水導入口11と、導入された水を噴出するインペラ14と、を有する複数のウォータージェット推進装置3と、を有し、複数のウォータージェット推進装置3は、船体2の左右方向において一対のスクリュープロペラ19間に配置されているウォータージェット推進アシスト型プロペラ推進船1を提供する。【選択図】図1
