HMS Comet was a pioneering vessel in the history of the Royal Navy, notable for being the first steamship built for the fleet. Completed in 1822, she was constructed with a wood hull at the yards of Boulton, Watt & Co in Deptford, just outside London. Designed by Oliver Lang, the master shipwright at Woolwich Dockyard, Comet was specifically built as a tugboat to assist larger ships by towing them out of harbors where wind conditions were insufficient for sailing. Her primary role was to tow Royal Navy ships in the Thames and Medway, facilitating their movement and operational readiness. The vessel featured a two-masted schooner rig, which provided her with sails as auxiliary propulsion, alongside her steam engine. Her power plant was a twin-cylinder side-lever engine rated at 80 nominal horsepower, making her the first of her kind in the Royal Navy and marking a significant technological advancement in maritime engineering. This combination of sail and steam capability exemplified the transitional period in naval propulsion technology. HMS Comet also played a role in scientific and technological testing; notably, in the summer of 1824, the famous scientist Humphry Davy traveled aboard her to Norway to evaluate zinc protectors for ships' copper bottoms, reflecting her utility beyond purely operational duties. After nearly five decades of service, HMS Comet was decommissioned and ordered to be broken up on 10 December 1868 at Portsmouth Dockyard. Her historical significance lies in her status as the Royal Navy’s first steam-powered vessel, representing the beginning of an era in naval propulsion that would eventually lead to the widespread adoption of steamships in maritime fleets.
