HMS Medusa was a Merlin-class paddle packet boat constructed for the Royal Navy in the late 1830s. She was one of three vessels in her class, characterized by a length of 175 feet at the gun deck and a keel length of approximately 153.5 feet. The ship had a beam of 33 feet 2 inches and a depth of hold of 16 feet 5 inches, with a burthen tonnage of 1,494 tons. Powered by a pair of steam engines rated at 312 nominal horsepower, Medusa's propulsion system drove her paddlewheels, making her suitable for rapid communication and mail delivery across the Irish Sea and Mediterranean regions. Her armament was modest, consisting of two 6-pounder carronades, reflecting her role primarily as a packet and dispatch vessel. Launched on 31 October 1838 and completed by August 1839, Medusa was initially based in Liverpool, serving as a packet ship in the Irish Sea. In 1848, she was modified for service in the Mediterranean, a region where she undertook various duties including mail transport. Notable incidents include running aground at Marseille in November 1849 while carrying mails from London to India; she was refloated with a broken rudder, and her mails were transferred via a French steamship. In 1851, Medusa was involved in a collision in Grand Harbour, Malta, with the brig Caroline; she was found to be at fault and was liable for damages. In the early 1860s, Medusa was converted into a tugboat at Woolwich, reflecting her evolving role within the Royal Navy. She remained in service until she was paid off in December 1871 and was subsequently sold for scrap in February 1872. Her service history underscores her versatility and the transition of naval vessels during the mid-19th century from dedicated packet ships to auxiliary roles such as tugs, highlighting her maritime significance within the Royal Navy's communication and support fleet.
