HMS Cockatrice was a cutter of the British Royal Navy, launched in 1781 as the fourth vessel of the Alert-class. Constructed with a burthen of approximately 181 tons, she was initially designed for home waters patrols and served in this capacity under various commanders. Her early service included duties in the English Channel, with notable commands by Lieutenant C. Bartholomew, Lieutenant William Reynolds, Lieutenant C. Hummer, and Lieutenant Walter Locke. During her time in service, Cockatrice participated in typical naval activities such as convoy escort, patrols, and the interception of enemy vessels, including Dutch and French ships, notably capturing or detaining several during the 1793 period. In 1801, Cockatrice sank at her moorings at Portsmouth but was subsequently refloated. The Navy decommissioned her in 1802, after which private interests purchased and significantly modified her. She was lengthened from her original dimensions, increasing her burthen from 181 to 195 tons, and was re-rigged as a brig. The private owners hired her back to the Navy, and she served as His Majesty's hired brig Cockatrice from 1804 to 1808. During this period, she was commanded by officers such as Lieutenant Nicholas Kemp and later P. Greene, undertaking convoy escort duties and capturing or recapturing vessels, including the brig Padgey and the ship Flora. In 1807, under Commander J. B. Balderston, Cockatrice was involved in the blockade and capture activities surrounding Danish vessels during the prelude to the Copenhagen attack. Her service was marred by reports of leaks and maintenance issues, with William Balfour describing her as leaky and poorly maintained in 1808. Her contract with the Navy ended that year, and she returned to mercantile service. Renamed and re-registered in Lloyd’s Register as a merchant vessel, Cockatrice continued trade routes from Liverpool to the West Indies and Africa, engaging in the slave trade and regional commerce. She participated in notable events such as carrying representatives of the King of Ashantee and was detained briefly in Barbados in 1813 for carrying unlicensed arms. Her final voyage ended in 1816 when she was condemned at Lisbon as unworthy of repair, marking the end of her maritime career.
