PURPOSE: A rolling reduction ship is provided to reduce the rolling of a hull by generating lifting force in a direction of disturbing rolling of the hull. CONSTITUTION: A rolling reduction ship comprises a hull, a right and left bilge keels(30,20), and a driving part(50). The hull has a center parallel part(12). The right side and left side bilge keel are expanded in the longitudinal direction of the hull. The right side and left side bilge keels are installed on a right side wall(12a) and left side wall(12b) of the center parallel part to rotate. The driving part supplies the rotation driving force for the right side and left side bilge keels. If the hull has rolling, the right side and left side bilge keels are rotated to generate the lifting force in the direction of disturbing rolling of the hull.
