This is what's called a bulbous bow and it's designed to reduce drag and increases stability, fuel efficiency, range, and speed.
The big round part of a bow on a ship is called the "bulbous bow." It extends outward from the hull below the waterline and is designed to improve the ship's hydrodynamics. By reducing wave resistance and improving fuel efficiency, the bulbous bow enhances the vessel's overall performance, especially at higher speeds.
To reduce wave drag on a ship at sea & to save on fuel costs.
From the "Bulbous Bow" entry in Wikipedia:A bulbous bow, a feature of many modern ship hulls, is a protruding bulb at the bow (or front) below the waterline. Usually visible only when a ship is in drydock, the bulb modifies how water flows around the hull, reducing drag and increasing in speed, range, and fuel efficiency. Ships with bulbous bows generally have 12 to 15 percent better fuel efficiency than similar vessels without them. Bulbous bows achieve maximum effect at a narrow range of speeds over 6 knots (Bray, website). At other speeds, they can increase drag. They have the greatest effect on large ships such as freighters, navy vessels and various passenger ships. They are rarer on recreational boats designed for wide speed ranges and planing over the water.
Some innovative ship bow designs currently used in the maritime industry include bulbous bows, wave-piercing bows, and X-bows. These designs help improve fuel efficiency, stability, and seakeeping abilities of ships.
the front of a ship is the bow. It is the point of the ship which is most often in forward motion.===============================================================bow. the front part of the boat is th bow front=BOW back=STERN left side=PORT SIDE right side=STARBOARD SIDE The front at the waterline is called the prow. The forward part of the deck is the fo'c'sle, from forecastle, and the most forward part of a sailing ship is the bowsprit.================================================================The front part of the ship is called the stem. It is connected to both the keelson and keel.===========================================================The pointed front part of a ship the "bow" can also be called the "prow" as an extension of the keel the front part of a ship can also be called the "stem".bow. its pronunciation rhymes with how and now; in other words, it is not pronounced the same as a bow tieThe front of the ship is called the bow. The back of the ship is called the stern.The bow, the foc'sle, the head, the bull nose, clipper bow, bulbous bow,cutwater, forepeak, hawse, stem foot.......The proper name for the front of a ship is bow. The bottom part is called the bilge, and the aft is the back part of the ship.The pointy end is called the bow (rhymes with cow). If you call it anything else you may get a stern warning.
The Front part of a boat or ship is known as the Bow.
The bow is the front of a ship.
The Bow is at the Front of a Boat/Ship
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.
The bow is the front end of the ship, with the stern being the back end.
The front part of a boat or a ship is called bow.
