PROBLEM TO BE SOLVED: To provide a marine vessel which reduces wave-making resistance at an ordinary water level, in a marine vessel with a large degree in enlargement of a hull form. SOLUTION: In the marine vessel, the block coefficient Cbf of a bow front half part is 0.88 to 0.96, and a water head calculated by (0.5×Vs×Vs)/g is identified as H, where Vs represents the sea speed of the marine vessel, and g represents gravitational acceleration. On a water plane of at least a part within the range of the H above and below a designed load draft, an angleβis set to be not less than (30-α×2/5) and nor more than (100-α×5/4) whereα°represents an angle where a hull center line is formed by a line segment connecting the position of a water line behind length Lpp between perpendiculars of a fore perpendicular by 1% to the fore perpendicular, andβ°represents an angle formed by the hull center line and a line segment connecting the position of the water line behind the length Lpp between perpendiculars by 10% from the fore perpendicular to the position of the water line behind the length Lpp between perpendiculars by 15% from the fore perpendicular.
