The invention discloses a novel bulbous bow with multi-draught resistance and belongs to the field of ship design. The novel bulbous bow is applicable to ships with various navigational draught conditions; each ship has a ballast draught state and a designed draught state. A transverse profile of the bow is concave around a ballast draught height; between the ballast draught height and the designed draught height and close to the designed draught height, the transverse profile is convex. The novel bulbous bow according to the technical scheme has the advantages that ballast draught state resistance is evidently improved, the designed draught and structural draught resistances are kept unchanged substantially, comprehensive oil cost of the multi-condition operating ship is lowered, economy is improved, and emission is reduced.
