To provide the bow structure of a ship which can manufacture the bow part projecting to the front side from the bow vertical line, by a simple combination of tube surfaces.
This bow structure is formed by projecting the bow part 4 projecting to the front side of a bow vertical line, to cross tube surfaces with a specific cross section form respectively at the hull center surface at the front side of the bow vertical line, from the left and the right sides of the bow. And by composing by providing a tubular projection 4 the width direction is narrowed as going to the bow front side, and a curved surface connecting the crossing parts of the tube surfaces smoothly, the manufacture of the bow part which has been considered difficult formerly is made possible to carry out easily, in a simple combination of curved surfaces to project the simple form of tube surfaces, not to be a complicated free curved surface, to the front side of the bow vertical line.
