Charlotte Dundas is regarded as the world's second successful steamboat, the first towing steamboat and the boat that demonstrated the practicality of steam power for ships. [1]
Development of experimental steam engined paddle boats by William Symington had halted when the sponsor, Patrick Miller of Dalswinton, abandoned the project. Symington had continued building steam pumping engines and mill engines. In 1793 he had developed a drive using a pivoted crosshead beam above the vertical cylinder to transmit power to a crank.
Miller's project and Captain John Schank's unsuccessful attempt at a canal steam tug had come to the attention of Thomas, Lord Dundas, Governor of the Forth and Clyde Canal Company, and at a meeting of the canal company's directors on 5 June 1800 approved his proposals on the basis of "a model of a boat by Captain Schank to be worked by a steam engine by Mr Symington".
The boat was built by Alexander Hart at Grangemouth to Symington's design with a vertical cylinder engine and crosshead transmitting power to a crank driving the paddlewheels. Trials on the River Carron in June 1801 were successful. This first boat may have been named Charlotte Dundas and the trials apparently included towing sloops from the river Forth up the Carron and thence along the Forth and Clyde Canal. There was concern about wave damage to the canal banks, and possibly the boat was found to be underpowered on the canal, so the canal company refused further trials.
In 1801 Symington patented a horizontal steam engine directly linked to a crank, and got the support of Lord Dundas for a second steamboat which would become famous as Charlotte Dundas, named in honour of his Lordship's daughter.
Symington designed a new hull around his powerful horizontal engine, with the crank driving a large paddle wheel in a central upstand in the hull, aimed at avoiding damage to the canal banks. The new boat was 56 ft (17.1 m) long, 18 ft (5.5 m) wide and 8 ft (2.4 m) depth, with a wooden hull. After a model of the boat was made and shown to Lord Dundas, the boat was built by John Allan, and the engine by the Carron Company.
The first sailing was on the canal in Glasgow on 4 January 1803, with Lord Dundas and a few of his relatives and friends on board. After some improvements, in March 1803 Charlotte Dundas towed two 70-ton barges 30 km (19 mi) along the Forth and Clyde Canal to Glasgow, and despite "a strong breeze right ahead" which stopped all other canal boats it took only nine and a quarter hours, giving an average speed of about 3 kilometres per hour (1.9 mph). This demonstrated the practicality of steam power for towing boats.
Plans to introduce boats on the Forth and Clyde canal were thwarted, largely by fears of erosion of the banks, and a project to build tug boats for the Bridgewater Canal had ended with the Duke of Bridgewater's death a few days before the March trial. Charlotte Dundas was left in a backwater of the canal at Bainsford until it was broken up in 1861. Symington was not paid all he had invested in construction of Charlotte Dundas and was left disappointed, but the development of steamboats was continued by others including Robert Fulton in the United States and Henry Bell in Scotland.
Robert Fulton was an American engineer and inventor who is widely credited with developing the world's first commercially successful steamboat, the North River Steamboat. In 1807, that steamboat traveled on the Hudson River with passengers from New York City to Albany and back again, a round trip of 300 nautical miles, in 62 hours. The success of his steamboat changed river traffic and trade on major American rivers.
The Forth and Clyde Canal is a canal opened in 1790, crossing central Scotland; it provided a route for the seagoing vessels of the day between the Firth of Forth and the Firth of Clyde at the narrowest part of the Scottish Lowlands. This allowed navigation from Edinburgh on the east coast to the port of Glasgow on the west coast. The canal is 35 miles (56 km) long and it runs from the River Carron at Grangemouth to the River Clyde at Bowling, and had an important basin at Port Dundas in Glasgow.
A steamboat is a boat that is propelled primarily by steam power, typically driving propellers or paddlewheels. Steamboats sometimes use the prefix designation SS, S.S. or S/S or PS ; however, these designations are most often used for steamships.
A tugboat or tug is a marine vessel that manoeuvres other vessels by pushing or pulling them, with direct contact or a tow line. These boats typically tug ships in circumstances where they cannot or should not move under their own power, such as in crowded harbors or narrow canals, or cannot move at all, such as barges, disabled ships, log rafts, or oil platforms. Some are ocean-going, and some are icebreakers or salvage tugs. Early models were powered by steam engines, which were later superseded by diesel engines. Many have deluge gun water jets, which help in firefighting, especially in harbours.
A paddle steamer is a steamship or steamboat powered by a steam engine that drives paddle wheels to propel the craft through the water. In antiquity, paddle wheelers followed the development of poles, oars and sails, where the first uses were wheelers driven by animals or humans.
Thomas Laurence Dundas, 1st Baron Dundas, FRS was a Scottish politician and peer who sat in the British House of Commons from 1763 to 1794 when he was raised to the peerage of Great Britain as Baron Dundas. He was responsible for commissioning the Charlotte Dundas, the world's "first practical steamboat".
William Symington (1764–1831) was a Scottish engineer and inventor, and the builder of the first practical steamboat, the Charlotte Dundas.
Patrick Miller of Dalswinton, just north of Dumfries (1731–1815) was a Scottish banker, shareholder in the Carron Company engineering works and inventor. Miller is buried in a tomb against the southern wall of Greyfriars Kirkyard in Edinburgh.
The PSComet was built in 1812 by Henry Bell, Scottish engineer from Helensburgh, and began a passenger service on 15 August 1812 on the River Clyde between Glasgow and Greenock that was the first commercially successful steamboat service in Europe.
The Clyde puffer is a type of small coal-fired and single-masted cargo ship, built mainly on the Forth and Clyde canal, which provided a vital supply link around the west coast and Hebrides of Scotland.
Eppleton Hall is a paddlewheel tugboat built in England in 1914. The only remaining intact example of a Tyne-built paddle tug, and one of only two surviving British-built paddle tugs, she is preserved at the San Francisco Maritime National Historical Park in San Francisco, California.
Daniel French (1770–1853), a "Yankee" inventor, was born in Berlin, Connecticut. From an early age French strove to become a "mechanician," an artisan trained in the theory of mechanics and skilled in the working of metals at increasing levels of precision. His friend Oliver Evans, an accomplished engineer, described French as an "original and ingenious inventor." French's most significant invention was the horizontally mounted, high-pressure, non-condensing, directly connected steam engine for mills, boats, etc. French was awarded a patent for his steam engine in 1809. This type of engine became standard on the western steamboat.
Henry Bell was a Scottish engineer who helped to pioneer the development of the steamship. He is mostly widely known for introducing the first successful passenger steamboat service on earth in 1812.
The Vulcan, launched in 1819, was the first all iron-hulled vessel (boat) to be built. It was designed as a horse-drawn passenger barge for use on the Scottish canals.
A marine steam engine is a steam engine that is used to power a ship or boat. This article deals mainly with marine steam engines of the reciprocating type, which were in use from the inception of the steamboat in the early 19th century to their last years of large-scale manufacture during World War II. Reciprocating steam engines were progressively replaced in marine applications during the 20th century by steam turbines and marine diesel engines.
TS King Edward was an excursion steamer built at Dumbarton for service down the River Clyde to the Firth of Clyde and associated sea lochs on the west coast of Scotland, as far as Campbeltown. The first commercial vessel to be driven by steam turbines, King Edward operated as a Clyde steamer for half a century from 1901 until 1951, interrupted only by service in the two world wars. The success of the vessel quickly led to the adoption of turbine propulsion for all manner of merchant vessels, from channel ferries and coastal steamers to transatlantic liners.
Steamboat services started on the Thames in around 1815 and for nearly 25 years were the main use of steam to carry passengers before the emergence of railways in the south of England. During this time at least 80 steamers are recorded in the Thames and the Steamboat Act of 1819 became the first statute to regulate the safety of the new technology for the public. Wooden boats driven by paddle-wheels, they managed during this time to establish themselves as faster and more reliable than the earlier use of sailing and rowing boats for passenger transport within the Thames estuary.
Mayflower is a steam tug built in Bristol in 1861 and now preserved by Bristol Museums Galleries & Archives. She is based in Bristol Harbour at M Shed. She is the oldest Bristol-built ship afloat, and is believed to be the oldest surviving tug in the world.
The Barony of Newton is a Scottish feudal barony located in the Parish of Bothkennar near Grangemouth, Stirlingshire. The Barony was erected on 3 April 1685 with Edward Wright as baron. The Barony was subsequently confirmed by Crown Charter issued under the Great Seal of George III, William Frederick, King of Great Britain and Ireland.
A return connecting rod, return piston rod or double piston rod engine or back-acting engine is a particular layout for a steam engine.
