The Pioneer Of Steam-Powered Boats: Henry Bell's Invention

The first steam-powered boat was invented by Scottish engineer Henry Bell in 1812. Bell is known for introducing the first successful passenger steamboat service in Europe, with the PS Comet. The Comet was built by Messrs John Wood and Co. in Port Glasgow and travelled from Port Glasgow to Glasgow, then from Glasgow to Greenock. The Comet was the first of many steam-powered boats that would change the course of history, revolutionising trade and transportation.

Henry Bell's background and early life

Henry Bell was born in 1767 in Torphichen, Linlithgowshire, Scotland. He served apprenticeships as a millwright and a ship modeler before moving to London to work and study under the Scottish engineer John Rennie. In 1790, Bell returned to Scotland, settling in Glasgow as a carpenter and later moving to Helensburgh. In 1800, he submitted proposals to the British Admiralty for steam-propelled vessels.

Bell's own steamship, the 28-ton Comet, was launched from Port Glasgow in 1812 and subsequently carried passengers and cargo along the Clyde River. The success of this vessel marked the beginning of the era of steam navigation in Europe.

The PS Comet's design and construction

The PS Comet was constructed for Henry Bell, a Scottish engineer, and his wife, who owned the Baths Hotel in Helensburgh. The ship was built by John and Charles Wood of John Wood and Company, shipbuilders of Port Glasgow. The PS Comet was a wooden vessel of around 30 tons, 40 feet in length, and 10 feet in beam, originally fitted with four paddle wheels (two on each side) and driven by a three-horsepower engine. The ship was brightly painted, with a female figurehead draped in rainbow colours. The interior featured a small cabin with wooden seats, beds, and a table.

The construction of the PS Comet was completed on January 18, 1812, and it was put into service on a 24-mile route between Greenock and Glasgow. The ship offered a first-class cabin for four shillings and a second-class cabin for three shillings. Despite initial losses and trust issues from passengers, the PS Comet proved to be a safe and secure means of transportation.

On the design front, the PS Comet underwent some changes over time. The original design with four paddle wheels was replaced by a single wheel on each side, and the length of the ship was extended by 20 feet to increase capacity. Additionally, two engines were fitted into the vessel at different times, though the exact dates of these changes are unknown.

In 1819, Bell had the Comet lengthened and re-engined, and it began a service to Oban and Fort William, a trip that took four days. Unfortunately, on December 15, 1820, the Comet was wrecked in strong currents at Craignish Point near Oban, with Bell on board. While there were no deaths, the vessel was lost. One of the engines was later salvaged and used to drive machinery at a brewery before finding its permanent home at the Science Museum in London.

The PS Comet's maiden voyage

The PS Comet, built for Scottish engineer Henry Bell, was the first commercially successful steamboat in Europe. On 15 August 1812, the Comet embarked on its maiden voyage, a passenger service on the River Clyde, connecting Helensburgh to Greenock and Glasgow. The 28-ton craft was built by John and Charles Wood of Port Glasgow and featured two paddle wheels on each side, driven by a single-cylinder engine. The engine was made by John Robertson of Glasgow, and the boiler by David Napier of Camlachie, Glasgow. The funnel doubled as a mast, with a yard allowing it to support a square sail when there was a following wind.

The Comet's trial run took place on 6 August 1812, travelling from Port Glasgow to Glasgow. The double paddlewheels were found to be unsatisfactory, and they were replaced with a pair of single wheels, increasing the vessel's speed to almost 7 knots. On its maiden voyage, the Comet offered a regular passenger service, travelling a distance of 25 miles each way between Glasgow, Greenock, and Helensburgh. The fare was "four shillings for the best cabin, and three shillings for the second."

The success of the Comet's maiden voyage and subsequent services quickly inspired competition, with rival steamboats offering trips down the Firth of Clyde and the sea lochs to Largs, Rothesay, Campbeltown, and Inveraray within four years. Henry Bell briefly tried a service on the Firth of Forth but soon faced competition and discontinued it.

The impact of the PS Comet's launch

The PS Comet, launched in 1812, was the first commercial passenger service in Europe. Sailing along the River Clyde in Scotland, the steamboat was a significant development in water-based transportation. Here are some impacts of the PS Comet's launch:

• Revolutionising River Travel: The PS Comet's launch marked a pivotal moment in the history of river transportation. As the first commercial passenger service in Europe, it set a precedent for river-based travel and commerce. The success of the PS Comet inspired similar ventures, leading to the development of steamboat services across Europe.
• Economic Growth: The introduction of steamboats on the River Clyde and other waterways contributed to economic growth. Steamboat services facilitated the transport of goods and passengers, connecting different regions and promoting trade. This economic impact was particularly evident in New Orleans, where the number of steamboat arrivals surged from barely 20 in 1814 to 1200 within two decades.
• Technological Advancements: The launch of the PS Comet spurred advancements in steamboat technology. Engineers and inventors sought to improve the design, efficiency, and power of steam-powered vessels. This led to the development of high-pressure steam engines, compound steam engines, and eventually, the more efficient steam turbine.
• Expansion of Steamboat Industry: The success of the PS Comet encouraged the expansion of the steamboat industry. Companies were established to operate steamboat services, and shipbuilders focused on constructing and improving these vessels. This growth created employment opportunities and stimulated economic activities related to shipbuilding, engineering, and river transportation.
• Social and Cultural Impact: The launch of the PS Comet had a social and cultural impact as well. Steamboat travel became a popular mode of transportation and even a source of entertainment. The vessels themselves, with their luxurious appointments and onboard amenities, reflected the social and cultural norms of the time.
• Influence on Other Regions: The launch of the PS Comet and its subsequent success influenced the adoption of steamboat technology in other regions. For example, the American Robert Fulton, who was present at the trials of the Charlotte Dundas (an early steamboat in Scotland), went on to design and operate steamboats in the United States.

The later life of Henry Bell

Henry Bell was born in 1767 in Torphichen, near Bathgate, West Lothian. He was the fifth son of Patrick Bell and Margaret Easton, both members of a family well known at the time as millwrights, builders, and engineers. Bell grew up at the local mill in Torphichen, where he developed a working knowledge of water power.

Bell's interest in steam-powered vessels began in 1800, when he approached the Admiralty with the idea of using steam to propel vessels against winds and tides. Despite the support of Lord Nelson, Bell was unsuccessful in this application and repeated the attempt in 1803 with the same result. Undeterred, Bell sent copies of his prospectus to other European nations and the United States. The Americans were the first to put his plan into practice, and Bell is credited with providing the first model of a working steamboat to Robert Fulton of America, with whom he corresponded regularly on the subject.

In 1808, Bell moved to Helensburgh, where he continued to pursue his favourite scheme. In 1809, he was elected as the first Provost of Helensburgh. In 1812, he and John Robertson built the PS Comet, a 30-ton steamboat with a three-horsepower engine. The Comet made a delivery voyage from Port Glasgow to Glasgow and then sailed from Glasgow to Greenock, making five miles an hour against a headwind. Bell advertised a passenger service on the Comet between Glasgow, Greenock, and Helensburgh three times a week, returning on alternate days.

Bell briefly tried a service on the Firth of Forth before having the Comet lengthened and re-engined. From September 1819, he ran a service to Oban and Fort William, a trip that took four days. However, in December 1820, the Comet was shipwrecked in strong currents at Craignish Point, near Oban. Bell built another vessel, Comet II, but in 1825, it collided with the steamer Ayr off Kempock Point, Gourock, and sank quickly, killing 62 of the 80 passengers on board. After this tragedy, Bell abandoned his work on steam navigation.

Bell lived to see his invention universally adopted and spent his later years in poverty. Touched by his condition, a subscription was raised on his behalf, and the trustees on the River Clyde granted him an annuity of £100, which was continued for his widow after his death in 1830.
