HMS Otter was the French merchantman Glanure, which the Royal Navy (RN) captured early in 1778.

The Royal Navy took her into service as the sloop HMS Otter and she served in the American theatre.

The quarry was Glanure, sailing from Rochelle to Charlestown with a cargo of dry goods and salt.

Perseus took the 43 man crew on board and Lizard took Glanure to St Augustine, arriving there on 9 March.

[5] While under the orders of Commodore Sir George Collier, in May 1779 Otter assisted at the capture and destruction of the towns of Norfolk, Suffolk, Portsmouth, Gosport, and others of less note in the vicinity of Elizabeth River; the strong posts of Stoney Point, Fort la Fayette, and Varplanks, up the North River; and the towns of Newhaven, Fairfield, Norwalk, and Greenfield, on the Connecticut shore; together with an immense quantity of shipping, merchandise, provisions, and naval and military stores.

[9] Otter also accompanied Sir George Collier to the Penobscot river, where nineteen sail of American armed vessels, and upwards of twenty transports, were either taken or destroyed, in August 1779.

[10] On 21 and 23 April 1780 Iris, Delaware, and Otter captured the American privateers Amazon, General Wayne, and Neptune.

[11] The capture had taken place a few leagues from Sandy Hook and Iris and Delaware brought them into New York on 1 May.

[a] Otter was among the vessels sharing in the prize money for the capture in October and November 1780 of the brigantines Surprise and Peggy, and the schooner Neilson.

[14] On 25 January 1781 HMS Blonde, Captain Andrew Barkley, Otter, and Delight, as well as some smaller vessels, carried 300 troops from Charleston to the Cape Fear River.

[15] The object of the expedition was to establish sea communications with Lord Cornwallis and provide a base for the army, which was moving north.

[20] A privateer captured three British slave ships off the west coast of Hispaniola on about 15 December 1795 as they were on their way to Jamaica.
