The ship John was originally launched in the Netherlands in 1785, likely under a different name, before being captured by the British in 1797. After her capture, she was renamed John and entered service as a merchant vessel. She was constructed with a burthen initially recorded as 260 tons, later corrected to 287 tons, and underwent a minor repair in 1798. Throughout her career, John primarily operated as a merchantman and participated in the transatlantic slave trade, making three documented slave voyages between 1800 and 1803. Her first slave voyage (1800–1801), under Captain John Kitts, departed Liverpool on 18 November 1800, arriving at Suriname on 20 April 1801, where she landed 76 slaves. She then returned to Liverpool on 17 September. Her second voyage (1801–1802), under Captain Samuel Reid, began on 28 November 1801, with the ship gathering slaves at Cape Coast Castle and delivering 280 to Kingston, Jamaica, on 10 July 1802. She sailed back to Liverpool by December, suffering two crew deaths during this trip. The third voyage (1803) saw Captain Charles King sail from Liverpool on 8 March 1803, with the ship gathering slaves at Gorée. During this voyage, John was captured by the French privateer Vengeance off the coast of Africa but was recaptured by the British ship Enterprize on 10 September 1803. She subsequently delivered 261 slaves to Dominica on 2 November. Following her slave trading period, John transitioned to a trader and transport vessel, her trade routes shifting to Liverpool–Africa and later to London. By 1806, her master was Macauley, and she was owned by Jeffrey. Her later career was as a London-based transport ship. Tragically, her service ended when the French privateer Confiance captured and burned her on 28 December 1809 in the Atlantic Ocean while she was on a voyage from London to São Miguel Island, with her crew taken to Brest. Her maritime significance lies in her dual role as a merchant vessel and a participant in the transatlantic slave trade, exemplifying the era's maritime commerce and conflict.
