Flank speed. Flank speed is an American nautical term referring to a ship 's true maximum speed but it is not equivalent to the term full speed ahead. Usually, flank speed is reserved for situations in which a ship finds itself in imminent danger, such as coming under attack by aircraft. Flank speed is very demanding of fuel and often ...
As a ship moves in the water, it creates standing waves that oppose its movement.This effect increases dramatically in full-formed hulls at a Froude number of about 0.35 (which corresponds to a speed/length ratio (see below for definition) of slightly less than 1.20 knot·ft −½) because of the rapid increase of resistance from the transverse wave train.
The highest speed ever reported is from the crew of Vestas Sailrocket 2 : on 24 November 2012 they recorded a top speed of 68.33 knots in a 25–29-knot wind. [12] Previously, the highest speed ever reported was from the crew of l'Hydroptère. During an attempt on 21 December 2008 at Port-Saint-Louis-du-Rhône, they recorded a top speed of ...
SS United States is a retired ocean liner built during 1950 and 1951 for United States Lines.She is the largest ocean liner constructed entirely in the United States and the fastest ocean liner to cross the Atlantic in either direction, retaining the Blue Riband for the highest average speed since her maiden voyage in 1952, a title she still holds.
Queen Mary 2 has a maximum speed of just over 30 knots (56 km/h; 35 mph) and a cruising speed of 26 knots (48 km/h; 30 mph), which is faster than a contemporary cruise ship. Instead of the common diesel-electric configuration, Queen Mary 2 uses integrated electric propulsion to achieve her top speed.
Drawing on a 1935 empirical formula for predicting a ship's maximum speed based on scale-model studies in flumes of various hull forms and propellers [N 5] and a newly developed empirical theorem that related waterline length to maximum beam, the Navy drafted plans for a battleship class with a maximum beam of 108 ft 2 in (32.97 m) which, when ...
The Spearhead-class expeditionary fast transport (EPF) is a United States Navy –led shipbuilding program to provide a high-speed, shallow draft vessel intended for rapid intra-theater transport of medium-sized cargo payloads. The EPFs can reach speeds of 35–45 knots (65–83 km/h; 40–52 mph), and allow the rapid transit and deployment of ...
Japanese battleship. Yamato. Yamato (Japanese: 大和, named after the ancient Yamato Province) was the lead ship of her class of battleships built for the Imperial Japanese Navy (IJN) shortly before World War II. She and her sister ship, Musashi, were the heaviest and most powerfully armed battleships ever constructed, displacing nearly 72,000 ...
