PROBLEM TO BE SOLVED: To provide an enlarged ship capable of reducing resistance by waves even when sailing in the waves in a light cargo state. SOLUTION: A ship bottom part of a bow part 2 is formed in a substantially V shape, and a projection part 7 is formed in a side surface part of the bow part 2. In a water line in DWL', a straight line of connecting a point of the hull front end on the hull center line and an intersection between a vertical surface of a rear position by a horizontal distance (0.02×Lpp) from the bow end 2a and the water line, becomes 0°<γ<55°in an angleγmeasured from the hull center line. In a frame line in a range being the rear by a horizontal distance (0.0125×Lpp to 0.05×Lpp), the projection part 7 has a place of becoming larger in a half width than a half width bbwl" in BWL" and a half width bdwl in DWL between the BWL" and the DWL.
