  HMS Centurion was a 80-gun second rate Vanguard-class ship of the line built for the Royal Navy in the 1840s.
  
  ## Description
  
  The Vanguard class was designed by Sir William Symonds, Surveyor of the Navy, with each ship built with a slightly different hull shape to evaluate their speed and handling characteristics. Centurion had a length at the gundeck of 190 feet 8 inches (58.1 m) and 153 feet 5 inches (46.8 m) at the keel. She had a beam of 57 feet 1 inch (17.4 m), a draught of 18 feet 10 inches (5.7 m) and a depth of hold of 23 feet 4 inches (7.1 m). The ship's tonnage was 2,589 83⁄94 tons burthen. The Vanguards had a wartime crew of 720 officers and ratings.
  
  The Vanguard class ships of the line were armed with twenty 32-pounder (56 cwt) cannon and two 68-pounder carronades on her lower gundeck, twenty-eight 32-pounder (50 cwt) cannon and another pair of 68-pounder carronades on the upper gundeck. On her quarterdeck were fourteen 32-pounder (42 cwt) cannon and on the forecastle deck were eight more 32-pounder (42 cwt) cannon.
  
  ### Modifications
  
  When Centurion was ordered to be modified for steam propulsion in 1854, she was fitted with a two-cylinder horizontal steam engine of 400 nominal horsepower that drove a single propeller shaft. On trials the engine produced 1,255 indicated horsepower (936 kW) which gave the ship a speed of 8.5 knots (15.7 km/h; 9.8 mph).
  
  ## Construction and career
  
  Centurion was ordered from Pembroke Dockyard on 18 March 1839 and laid down the following July. She was launched on 2 May 1844 and completed on 10 June. The ship was not fitted out and Centurion was placed in ordinary. Her construction cost £57,386. Between September 1854 and November 1855, she was fitted with steam propulsion.
  
  Centurion was sold for scrap on 19 March 1870, for a price of £8200.
