Category: General

A bulbous ships bow is a feature of many modern ships hulls.It is characterized by a protruding bulb at the bow of the ship below the water line.Due to this ,a bulbous bow is usually only visible when the ship is in dry dock or out of ballast waiting to load cargo and therefore floating higher than usual when at sea.The presence of this bulb modifies the flow of water around the hull,thereby reducing drag[friction] and affording an increase in speed,range and fuel efficiency.In ships that have had bulbous bows fitted,gains in fuel efficiency of between 12 and 15% are standard.As these factors are particularly important for almost all applications of maritime vessels,bulbous bows have seen widespread adoption since their development
