Arniston was an East Indiaman that made eight voyages for the British East India Company (EIC). She was wrecked on 30 May 1815 during a storm at Waenhuiskrans, near Cape Agulhas, South Africa, with the loss of 372 lives – only six on board survived. She had been chartered as a troopship and was underway from Ceylon to England on a journey to repatriate wounded soldiers from the Kandyan Wars. Controversially, the ship did not have a marine chronometer on board, a comparatively new navigational instrument that was an "easy and cheap addition to her equipment" that would have enabled her to determine her longitude accurately. Instead, she was forced to navigate through the heavy storm and strong currents using older, less reliable navigational aids and dead reckoning. Navigational difficulties and a lack of headway led to an incorrect assumption that Cape Agulhas was Cape Point. Consequently, Arniston was wrecked when her captain headed north for St Helena, operating on the incorrect belief the ship had already passed Cape Point. Overview East Indiamen operated under charter or licence to the Honourable East India Company, which held a monopoly granted by Queen Elizabeth I of England for all English trade between the Cape of Good Hope and Cape Horn. Arniston was built by William Barnard at Barnard's Thames Yard at Deptford on the Thames and launched in 1794.Mitchell 2007, tertiary sources. She was probably named after Lord Arniston rather than the tiny village of Arniston near Edinburgh. Arniston was heavily armed, with her fifty-eight guns making her the equivalent of a Royal Navy fourth-rate ship of the line. A classification of "ship of the line" – a class of ship that later evolved into the battleship – meant that a ship was powerful enough to stand in a line of battle and explained why these ships of commerce were sometimes mistaken for men-o-war. The armament was necessary for the ship to protect herself and her valuable cargo from pirates and commerce raiders of other nations during long voyages between Europe and the Far East. Arniston, like other East Indiamen, was slow and unmanoeuvrable, but able to carry a large quantity of cargo. Voyages (1794–1812) For her first five voyages she sailed under the ownership and management of John Wedderburn (probably John Wedderburn of Ballindean) and the next three EIC voyages under ownership of Robert Hudson. Arniston sailed from Great Britain to
