Claims

[Scope of Claim for Utility Model Registration] A double-ender ship with propellers placed on the bow and stern sides, the main propulsion of which is a rotating thruster that can generate thrust in any direction within a plane of 360° at symmetrical positions on both ends of the ship. At the same time, the ship's hull is formed into a tunnel-like structure from this rotating thruster toward the ship's center of gravity, so that the wake of the thruster on the bow side does not collide with the ship's body as much as possible, and the thruster is placed on the stern side. A double-ender ship characterized by the fact that the water flow flowing into the propeller is not obstructed.
