PROBLEM TO BE SOLVED: To provide a marine vessel an enlarging degree of a vessel form of which is large, a bow end of which is a vessel form near to a fore perpendicular (F.P.), capable of reducing long-run average water flow medium wave making resistance, restraining wave intermediate resistance increase and restraining sea water driving. SOLUTION: A shape of a lateral cross-section of a flare of a bow part above the maximum draft ZO is formed by having a recessed part 10 constricted to the side of a hull central line C.L. from a vertical line L(x) and height Hm of a center of the recessed part 10 is made height in a range of more than 0.5 time and less than 3.0 times of water head hl calculated by (0.5×Vs×Vs)/g when sea speed of the vessel is specified as Vs and gravitational acceleration is specified as (g) on the upper side of the maximum draft ZO in a region between a position of a bore end Xf and a position of at least 10% of length between perpendiculars Lpp in the rear of the fore perpendicular F.P. concerning the vessel lengthy direction.
