HMS Otter was a Merlin-class sloop of the Royal Navy, launched in 1805 at Hull. She was armed with a total of 16 guns, comprising sixteen 32-pounder carronades and two 6-pounder long guns, and was officially rated as a 16-gun vessel, later re-rated as 18 guns from 1815 without change to her armament. Displacing approximately 365 tons, she was designed for versatility and agility in naval operations. Constructed and commissioned in 1805 under Commander John Davies, HMS Otter initially served with the Channel Fleet. Early in her service, she recaptured the Enterprize in 1807 and shared in salvage operations following the recapture of Farely. In August 1807, she sailed to the Cape of Good Hope and subsequently supported British military efforts in South America, including an attempted attack on Montevideo, which was thwarted after British forces were defeated. Under Commander Nesbit Willoughby, Otter captured the Danish vessel Harregaard at the Cape in 1808. Throughout her service, HMS Otter participated actively in the Napoleonic Wars, including joint captures of slave ships and vessels such as the French brig Lucie and others, often in cooperation with vessels like Nereide and Leopard. She was part of the squadron under Commodore Josias Rowley tasked with blockading French colonies Île de France and Île Bonaparte in the Indian Ocean. Notably, in 1809, Otter’s boats engaged at Riviere Noire, and she took part in the Raid on Saint Paul in September 1809, where her commanding officer, Willoughby, was promoted for his leadership. Otter’s operational role extended to supporting actions against French vessels and participating in the invasions of Île de France in December 1810. Her efforts in these campaigns earned her recognition, including the clasp "Otter 18 Sept. 1810" to the Naval General Service Medal awarded in 1847 to surviving participants. After her active service, she was fitted for ordinary at Plymouth in 1811, then served as a quarantine lazaretto at Pembroke in 1814. Finally, the Royal Navy sold HMS Otter in 1828 to J. Holmes for £610, marking the end of her distinguished naval career.
