A costa bulb, often referred to as a bulbous bow, is a protruding underwater extension on a ship's hull, typically located near the rudder. Its design helps to reduce drag and improve fuel efficiency by altering the water flow around the hull, which can enhance stability and speed. While primarily associated with the bow, similar bulbous features can also be found near the rudder to optimize performance and maneuverability. These innovations contribute to better hydrodynamics, making vessels more efficient in their operations.
