Claims

[Scope of utility model registration request]

In a waterjet propulsion system consisting of a duct leading from the bottom opening to the stern opening and an impeller installed in the duct, the impeller uses water to blow out the waterjet from the bottom opening when suppressing the motion of the ship. What is claimed is: 1. A propulsion device that also functions as a hull sway reduction device, characterized in that it is provided with a device that can switch the driving direction to the opposite direction.
