Remember Titanic? You must have observed it didn’t have a bulbous bow. But try having a look at the bows of modern cruise ships, container ships, LNG carriers, research vessels, etc.
The bulbous bow concept is credited to David W. Taylor, a naval architect who served as Chief Constructor of the United States Navy during the First World War and who used the concept (known as a bulbous forefoot) in his design of the USS Delaware, which entered service in 1910.
A normal bow is cheaper to manufacture and a bulbous bow should only be fitted if doing so will reduce the resistance and thereby either increase the speed or reduce the power required, and with it the fuel consumption.
Now essentially all cruise ships have a bulbous bow. “It is designed to decrease the hydrodynamic drag of the ship. Having a bow like that on a ship increases the efficiency by about seven percent or saves us about seven percent in fuel, which ever way you like.
What type of bow did Titanic have?
Consider a ship with a straight bow (for example, Titanic). As the ship surges forward, the water particles move towards the stern along the entire length of the ship.

The first bulbous bows appeared in the 1920s with the “Bremen” and the “Europa”, two German passenger ships built to operate in the North Atlantic. The “Bremen”, built in 1929, won the Blue Riband of the crossing of the Atlantic with the speed of 27.9 knots.
What does a bulbous bow do for a ship?
1 INTRODUCTION. Bulbous bow can help to reduce a ship’s resistance and thus to save the fuel consumption up to 15%, however, it is also regarded as a threat to a struck ship in collision accidents because it may generally penetrate the side shell of the vessel, which may cause the leakage of hazardous goods.
Why do some ships not have bulbous bows?
Vessels of lower mass (less than 4,000 dwt) and those that operate at slower speeds (less than 12 kts) have a reduced benefit from bulbous bows, because of the eddies that occur in those cases; examples include tugboats, powerboats, sailing vessels, and small yachts.
Do all ships have a bulbous bow?
But try having a look at the bows of modern cruise ships, container ships, LNG carriers, research vessels, etc. All of them are characterized by a bulbous bow. Not only monohull ships, today almost even catamarans are equipped with a bulbous bow rather than straight bows.

What was the first ship to have a bulbous bow?
The “Yamashiro Maru”, built on 1963 at the Mitsubishi shipyard in Japan, was the first ship equipped with a bulbous bow. The ship attained the speed of 20′ with 13.500 hp while similar ships needed 17.500 hp to reach the same speed.
Why do cruise ships have a bulbous bow?
A bulbous bow is an extension of the hull just below the load waterline. The basic purpose is to create a low-pressure zone to reduce or eliminate the bow wave and reduce the resulting drag. Today the bulbous bow is a normal part of modern seagoing cargo ships.
Why do new cruise ships have straight bows?
The new vertical bow is said to be more efficient and provide sea-keeping abilities that are equal to or greater than the traditional flared bow. It is also said to cause less stress and strain on the vessel as she slices through heavy seas instead of trying to part them as the usual flared bow does.
Do yachts have bulbous bows?
As a matter of fact, all N86 boats have a bulb built in. However, for smaller yachts, the presence of the bulbous bow is actually more of an inconvenience because of the amount of noisy slapping or pounding on the hull especially when traveling on rough seas.
