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.^[1] The Vanguards had a wartime crew of 720 officers and ratings.^[2]

The Vanguard class ships of the line were armed with twenty 32-pounder (56 cwt)^{[Note 1]} 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.^[2]

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).^[3]
