The Aaron Manby was a pioneering iron steamship launched in 1821, notable for being the first vessel of its kind to go to sea. Constructed at the Horseley Ironworks in Tipton, Staffordshire, the ship was pre-fabricated to a design developed collaboratively by Captain Charles Napier, Aaron Manby, and Manby's son Charles. The vessel was then transported in pieces to Rotherhithe on the Thames, where it was assembled. She measured approximately 120 feet (37 meters) in length with a tonnage of 116 tons burthen, featuring a flat-bottomed hull constructed from 1/4-inch-thick (6.4 mm) iron plates fastened to angle-iron ribs. The ship had a single wooden deck and was equipped with a bowsprit and a distinctive 47-foot-high (14 meters) funnel. Her propulsion system was an oscillating steam engine, designed and patented by Aaron Manby (British Patent No. 4558 of 1821). The paddlewheels, each 12 feet (3.7 meters) in diameter and 2.5 feet (76 centimeters) wide, were limited by the vessel’s beam of 23 feet (7 meters). Remarkably, despite the prevailing skepticism of the era, Aaron Manby floated successfully and achieved speeds of around 9 knots (10 mph; 17 km/h), drawing only one foot (30 cm) of water, less than any other steamboat of her time. In June 1822, under Captain Napier, Aaron Manby made a historic voyage across the English Channel from Rotherhithe to Le Havre, averaging 8 knots and carrying passengers, cargo of linseed, and iron castings. She then proceeded up the Seine to Paris, where she caused considerable excitement and was based for approximately ten years. This voyage is often incorrectly cited as the first from Britain to France by steamship; however, it was also the first direct steam crossing from London to Paris and the first seagoing voyage by an iron ship globally. After additional channel trips and pleasure cruises on the Seine, the vessel was sold in 1827 following Napier's bankruptcy. She was acquired by a French company and operated on the River Loire until her dismantling in 1855. The Aaron Manby’s innovative iron hull design influenced shipbuilding practices significantly, serving as a precursor to later iron warships, including the Royal Navy’s first iron frigate, HMS Warrior. Her historic crossings and pioneering construction marked her as a vessel of great maritime significance, heralding a new era in ship design and technology.
