シング構造。The bottoming that surrounds the rear end of the propeller shaft of a multi-shaft ship with propellers on both port and starboard sides of the stern has a fillet that connects the bottoming to the hull, and the fillet directs the flow of water in the opposite direction to the rotation of the propeller. The fillet is formed by bending the trailing edge of the fillet so as to be able to rotate, and at least one fin that can change the flow of water in a direction opposite to the rotation of the propeller is provided protruding from the rear end of the bottoming. A finned bossing structure for a multi-shaft ship, characterized by
