A ship including an engine, a jet propulsion device, a ship controller, and a ship position detection unit, in which the jet propulsion device includes a nozzle that ejects a jet stream generated by the driving force output from the engine, and a bucket that changes a direction of the jet stream, the position of the bucket includes at least a forward position where the jet propulsion device generates a propulsive force for moving the ship forward, a neutral position where the jet propulsion device does not generate a propulsive force for moving the ship, and a forward-side intermediate position between the forward position and the neutral position, the ship controller has a ship fixed point holding mode in which feedback control of the engine and the jet propulsion device is performed based on a deviation between a preset target ship position and the actual ship position, and both control of the position of the bucket including the forward-side intermediate position and control of a rotational speed of the engine are performed in the ship fixed point holding mode.
