A ship having a rudder bulb is disclosed. The ship having a rudder bulb according to an embodiment of the present invention comprises a hull; and a bulb-type rudder assembly disposed adjacent to a propeller at the rear of the hull to adjust a traveling direction of the hull, wherein the bulb-type rudder assembly comprises: a rudder body for adjusting the direction of travel of the hull; a rudder bulb coupled to the rudder body between the propeller and the rudder body in order to increase the propulsion efficiency of the hull by reducing an axial loss occurring in a wake of the propeller; and a fluid flow direction control part provided in the rudder bulb, and controlling the flow direction of the fluid flowing along the surface of the rudder bulb in the propeller region during the operation of the hull, thereby capable of increasing the propulsion efficiency of the hull.
