Abstract : To reduce the total ship resistance and to improve a Propeller efficiency and cavitation performance due to the reduced thrust loading on the propeller for ships or vessels having a sonar dome or an equivalently shaped designs located below the baseline of the hull, a tear-drop-shaped bulbous bow is attached to the ship stem bow between the forward perpendicular of the bow and 12.7 ft forward of the forward perpendicular of the vessel, inclusive, and between the ship design waterline and the baseline.
