WHAT DOES BULBOUS BOW MEAN IN ENGLISH?

bulbous bow

Bulbous bow

A bulbous bow is a protruding bulb at the bow of a ship just below the waterline. The bulb modifies the way the water flows around the hull, reducing drag and thus increasing speed, range, fuel efficiency, and stability. Large ships with bulbous bows generally have a twelve to fifteen percent better fuel efficiency than similar vessels without them. A bulbous bow also increases the buoyancy of the forward part and hence reduces the pitching of the ship to a small degree. Bulbous bows have been found to be most effective when used on vessels that meet the following conditions: ▪ the waterline length is longer than about 15 metres ▪ the vessel will operate most of the time at or near its maximum speed Thus, large vessels that cross large bodies of water near their best speed will benefit from a bulbous bow. This would include naval vessels, cargo ships, passenger ships, tankers and supertankers. All of these ships tend to be large and usually operate within a small range of speeds close to their top speed. Bulbous bows are less beneficial in smaller craft and may actually be detrimental to their performance and economy.
