Construction of RMS Titanic, funded by the American J.P. Morgan and his International Mercantile Marine Co., began on 31 March 1909. Titanic‘s hull was launched at 12:13 on 31 May 1911, and her outfitting was completed by 31 March the following year. Her length overall was 882 feet 9 inches (269.1 m), the moulded breadth 92 feet 0 inches (28.0 m), the tonnage 46,328 GRT, and the height, from the water line to the boat deck, 59 feet (18 m). She was equipped with two reciprocating four-cylinder, triple-expansion steam engines and one low-pressure Parsons turbine, each driving a propeller. There were 29 boilers fired by 159 coal burning furnaces that made possible a top speed of 23 knots (43 km/h; 26 mph). Only three of the four 62 foot (19 m) funnels were functional: the fourth, which only provided ventilation, was added to make the ship look more impressive. The ship could carry a total of 3,547 passengers and crew.
