HMS Moira, also known as HMS Earl of Moira, was a British 14-gun schooner built in 1805 at Kingston Royal Naval Dockyard in Upper Canada. Designed by Alexander Munn and constructed under the supervision of Master Shipwright John Dennis, she measured approximately 168 tons burthen, with an overall length of 70 feet 6 inches and a keel length of 56 feet 3 5/8 inches. Her beam was 23 feet 8 inches, and she had a draught of 7 feet. Originally rigged as a schooner, she was re-rigged as a brig in 1813 to improve her combat capabilities. Initially armed with 14 guns as a schooner, her armament evolved throughout her service: she was re-armed with two 9-pounder guns and fourteen 24-pounder carronades after her re-rigging, and by 1814, her armament was adjusted to a single 18-pounder gun and twelve 24-pounder carronades. Her design was intended for service on Lake Ontario and the St. Lawrence River during the War of 1812, where she played an active role in naval engagements. During the war, HMS Moira participated in various operations, including blockades, troop transports, and engagements with American vessels. Notably, she was part of the British squadron that attempted to cut off American shipping and supported land operations such as the attack on Fort Oswego. Her service record includes participating in the Second Battle of Sacket’s Harbor and engaging American ships like the USS Madison and Oneida. Her crew was periodically reduced, and in 1813 she was converted from a schooner into a brig to enhance her combat effectiveness. After the war, the vessel was renamed Charwell in 1814 and served as a powder hulk from 1816 and later as an accommodation vessel in 1827. She was ultimately sold in 1837. HMS Moira’s operational history highlights her significance as a versatile and active vessel during the War of 1812, embodying the naval efforts on Lake Ontario and contributing to British control of the Great Lakes region during the conflict.
