HMS St Vincent was a formidable 120-gun first-rate ship of the line of the Royal Navy, launched on 11 March 1815 from Devonport Dockyard. As one of a class of three, she was the only vessel in her class to see active service. Although completed in 1815, she was not commissioned until 1829, when she served as the flagship of William Carnegie, 7th Earl of Northesk, under the command of flag captain Edward Hawker at Devonport. Her early service included a deployment in the Mediterranean from 1831 to 1834. Notably, on 18 February 1834, while at Malta, she was involved in a collision caused by the explosion of the merchant schooner Meteor's cargo of gunpowder, which resulted in the loss of 28 lives. The explosion also severely damaged HMS St Vincent, forcing her aground. She was refloated after removing all 120 of her cannons and subsequently repaired to return her to service. In the subsequent decades, HMS St Vincent was placed on harbor service at Portsmouth in 1841 and joined the Experimental Squadron in 1846. From May 1847 to April 1849, she served as the flagship of Rear-Admiral Sir Charles Napier in the Channel Fleet. During the Crimean War in 1854, she transported French troops to the Baltic and later served as a depot ship at Portsmouth. She was driven ashore in January 1862 but was refloated and transitioned into a training ship for boys, moored at Haslar from 1870 onward. Retaining 26 guns, she served as a training vessel until 1905, with command passing through several officers, including Cecil Thursby and Bentinck J. D. Yelverton. The ship was decommissioned in 1906 and subsequently broken up at Falmouth Docks. One of her anchors was preserved and displayed near Gyllyngvase Beach in Falmouth, marking her maritime significance as a symbol of naval history and training.
