Abstract

PROBLEM TO BE SOLVED: To increase a propulsion efficiency by collecting a rotation energy of a propeller slip stream. SOLUTION: A pod 2 is provided on a stern hull 10 through a rotation shaft 1 rotatable about a vertical axis. A propeller driving motor 3 is stored in a pod 2. A propeller 5 is mounted on a rear end of a propeller shaft 4. The pod 2 is provided with a reaction fin 6 at a rear end, i.e., a position in the upstream of the propeller 5. The reaction fin 6 is provided with multiple fin blades in a radial pattern rotating a flow flowing into the propeller 5 in the direction opposite to the rotation direction of the propeller 5. Rotating the flow flowing into the propeller 5 in the direction opposite to the rotation direction of the propeller 5 beforehand reduces a rotation energy of a slip stream of the propeller 5, thereby increasing a propulsion efficiency.
