HMS Geyser (1841)

HMS Geyser was a Driver-class wooden paddle sloop of the Royal Navy constructed in 1841 and broken up in 1866.

Design and construction
Geyser was ordered on 12 March 1840 as the fourth of a class of 6 second-class steam vessels. She was laid down in Aug 1840 and launched on 6 April 1841. She was 180 ft long on the gundeck and displaced 1,590 tons. Power for her paddles came from a Seaward & Capel 2-cylinder direct-acting steam engine developing 280 nominal horsepower, which was fitted at Woolwich in May 1841. Having conducted engine trials in the River Thames, she left Woolwich for Sheerness on 31 October 1841 to be coppered and made ready for sea. She was commissioned for the first time at Sheerness on 8 March 1842.

Service history
She served in the Mediterranean and the Levant in 1846. By December 1848 she was at the Cape of Good Hope. On 16 February 1850 she rescued the survivors of the barque Childe Harold, a passenger ship homeward bound from Australia. Childe Harold had struck the south east point of Dassen Island on the West Coast of South Africa. The only fatality was the Master, James Byres, who drowned while attempting to swim ashore with a line.

She spent much of 1851 conducting anti-slavery patrols off the coast of Brazil. On 11 February 1851 she captured the slave brig Mangano in the vicinity of Rio de Janiero. The slaver was sent for adjudication to the Vice-Admiralty Court at St. Helena, and in June 1851 she was sentenced to be restored to her master without costs.

She was present at the Fleet Review at Spithead on 23 April 1856, and in 1857 was at Simon's Town in South Africa for patrols off the East Coast of Africa. On 23 June 1860 she was recommissioned at Devonport for service on the Home Station as a storeship.

Fate
Geyser was broken up in 1866.
