HMS Chatham was a 74-gun third-rate ship of the line of the Royal Navy, launched in 1812. Originally, she was intended to serve in the French Navy as the Royal-Hollandais, a vessel of the Pluton class, a smaller variant of the Téméraire-class ships. Construction began in Flushing, in the Kingdom of Holland, but during the Walcheren Campaign in 1809, the town fell to British forces. The ship's frames were dismantled, transported to London, and reassembled at Woolwich Dockyard, where she was launched on 14 February 1812 and completed by 25 April 1812. She measured approximately 1,860 tons burthen, with a length of 177 feet 9 inches on the gun deck and a keel length of 146 feet 8 inches. Her beam was 48 feet 10 inches, and her depth in the hold was 21 feet 6.5 inches. The vessel was crewed by around 590 men. Her armament comprised twenty-eight 32-pounder guns on the lower gundeck, twenty-eight 24-pounders on the upper gundeck, along with four 12-pounders and ten 32-pounder carronades on the quarterdeck. She also carried two 12-pounders and two 32-pounder carronades on her forecastle, plus six 18-pounder carronades on her roundhouse. Due to poor quality timber used during her construction, HMS Chatham's service life was notably short. She was commissioned in March 1812 under Captain Graham Moore, later succeeded by Captain Robert Maunsell in September. During her brief service, she served as the flagship of Rear-Admiral Matthew Scott in the North Sea. By July 1814, she was reduced to a sheer hulk, and following the end of the Napoleonic Wars, she was laid up at Chatham Dockyard in November 1815. The vessel was sold for breaking up in 1817 for £5,110, marking a brief but notable presence in Royal Navy history.
