PROBLEM TO BE SOLVED: To provide a control device for an electric propulsion vessel, a control system for an electric propulsion vessel, and an electric propulsion vessel capable of changing vessel speed without using an invertor or a variable pitch propeller and especially capable of starting an induction motor without having starting current be excessive.SOLUTION: A control device for an electric propulsion vessel includes a synchronous generator 20 driven by an engine 10, a magnetization regulator 62, an induction motor 30 to which a propeller 40 is connected, and start-up setting means 91. A first power generation control mode for controlling power generation voltage of the synchronous generator 20 by adjusting engine speed of the engine 10 by engine speed control means and a second power generation control mode for controlling power generation voltage of the synchronous generator 20 by the magnetization regulator are switched and linked based on engine speed of the engine 10 or frequency of the synchronous generator 20 or power generation voltage of the synchronous generator 20 as well as power generation voltage of the synchronous generator 20 is gradually increased from 0 V and changed when starting is set at the start-up setting means 91 as the second power generation control mode.SELECTED DRAWING: Figure 2
