The terms used in the various embodiments of this disclosure are used merely to describe specific embodiments and are not intended to limit the various embodiments of this disclosure. The singular expression includes the plural expression unless the context clearly indicates otherwise. In the drawings, the size of components may be exaggerated or reduced for convenience of explanation. For example, the size and thickness of each component shown in the drawings are depicted arbitrarily for convenience of explanation, so the following embodiments are not necessarily limited to those illustrated. Unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as generally understood by those skilled in the art to which the various embodiments of this disclosure pertain. In the following embodiments, terms such as "include" or "have" mean that the features or components described in the specification are present, and do not preclude the possibility that one or more other features or components may be added. FIG. 1 is a drawing illustrating a ship including a propulsion assist device for a ship according to one embodiment of the present invention. In the following, 'forward' is defined as the direction toward the bow of the vessel (10) based on the configuration to be described, and 'rear' is defined as the direction toward the stern of the vessel (10) based on the configuration to be described. In the following, 'inflow' is defined as fluid flowing into the propeller (200) from the front of the propeller (200). A vessel (10) according to one embodiment of the present invention is not limited to a specific use or function and can be applied in various ways for industrial or commercial purposes. For example, the vessel (10) may be an industrial vessel for logistics, such as an oil tanker or a container ship, or a vessel for military purposes, such as a destroyer or a frigate, but is not limited thereto.
