PROBLEM TO BE SOLVED: To provide a vessel, capable of making a flow on a propeller/disc surface further uniform, and reducing the generation of vibrations of a vessel body accompanying propeller action and the generation of propeller cavitation, in a propeller propulsion vessel of a twin skeg type. SOLUTION: In the vessel 1A of the twin skeg type which has a square coefficient of 0.65 to 0.90, and in at least one of a cross section vessel body shape X1 within a range in 25 to 30% front of a run length Lr from a stern perpendicular line AP, vessel body width B1o on an outer side than a shaft center SC has the local maximum value B1om at a water line position d1m above a base line BL by the height of 30 to 90% of shaft center height dsc. At the water line position d1m, the whole vessel body width B1m of one board is 10 to 25% of the vessel body width at full load draft, and the outside vessel body width B1om becomes larger than the inside vessel body width B1im.
