Description

The Algésiras-class ships were repeats of the pioneering ship of the line Napoléon and were also designed by naval architect Henri Dupuy de Lôme. They had a length at the waterline of 71.23 metres (233 ft 8 in), a beam of 16.8 metres (55 ft 1 in) and a depth of hold of 8.16 metres (26 ft 9 in). The ships displaced 5,121 tonnes (5,040 long tons) and had a draught of 8.45 metres (27 ft 9 in) at deep load. Their crew numbered 913 officers and ratings.^[1]

The primary difference between Napoléon and the Algésiras class was that the boilers of the latter ships were moved forward of the engines. They were powered by a pair of two-cylinder horizontal-return connecting-rod steam engines, also designed by Dupuy de Lôme, that drove the single propeller shaft using steam provided by eight boilers. The engines were rated at 900 nominal horsepower and produced 2,057 indicated horsepower (2,086 PS; 1,534 kW). During her sea trials, Algésiras reached a sustained speed of 13 knots (24 km/h; 15 mph). The ships were fitted with three masts and ship rigged.^[1]

The armament of the Algésiras-class ships consisted of eighteen 36-pounder (174.8 mm (6.9 in)) smoothbore cannon and sixteen 223.3 mm (8.8 in) Paixhans guns on the lower gundeck and thirty-four 30-pounder 164.7 mm (6.5 in) cannon on the upper gundeck. On the quarterdeck and forecastle were twenty 163 mm (6.4 in) Paixhans guns and a pair of 163 mm rifled muzzle-loading guns.^[1]

Career

In 1859, she took part in the blockade of Venice and various operations in the Mediterranean during the Second Italian War of Independence.^[2]

She was decommissioned in 1865 and used as a transport. She was later used as a school ship.^[2]

On 25 November 1906, she was destroyed in Toulon by an accidental fire.^[2]
