A seagoing vessel is provided with a bow bulb composed of a main body, integral with the vessel's hull and a covering cowl member, which is swingable about horizontal hinges at its rear end. In fully loaded/stationary condition the top ridge of the cowl member just touches the water level. Remotely controlled power motors between the main body and the cowl will raise the forward end of the cowl, so it maintains contact with the occasional water level caused by damming due to the speed of the ship in motion.
