HMS Acheron was the last vessel of the Hermes-class wooden paddle sloops constructed for the Royal Navy, launched at Sheerness in 1838. Designed as a relatively small, paddle-powered warship, she was built with a wooden hull and equipped with machinery for steam propulsion, reflecting the transitional period in naval engineering. Her initial cost was £25,509, which included rigging and machinery. The vessel measured approximately 180 feet in length, with a beam of about 27 feet, and was rigged for sail alongside her steam engine, enabling versatility in her operations. Constructed at Sheerness Dockyard, Acheron was ordered in September 1837, laid down in October, and launched on 23 August 1838. She was commissioned shortly thereafter under Lieutenant Andrew Kennedy for service in the Mediterranean, where she completed her first commission, returning to Home Waters and paying off in December 1841. Her second commission began in December 1842, again in the Mediterranean, with Lieutenant Benjamin Alpin at the helm. She paid off in October 1847 after her second Mediterranean tour. In 1847, Acheron was reclassified as a survey ship, reflecting her evolving role within the Royal Navy. Under the command of Captain John Lort Stokes, RN, she was dispatched to the East Indies Station in 1849 for coastal survey work in New Zealand, a significant undertaking as it was the first such survey since Captain Cook. She arrived in New Zealand in November 1849 and conducted extensive surveying until 1851. During her time in Australia, she participated in rescue missions, notably saving the crew and passengers of the wrecked merchant ship Syrian in 1851 and the British barque Tory in 1853. Acheron was laid up in Sydney in 1851 due to budget cuts but continued her service as a rescue vessel. She was ultimately sold at Sydney in April 1855 for £2,067 16s. Her career highlights include her role in early hydrographic surveying and maritime rescue operations, marking her as a vessel of maritime significance during a period of naval transition from sail to steam and from traditional warship to survey vessel.
