Who made the first steam boat?

Answer 1

Patrick Miller of Dalswinton, near Dumfries, Scotland, had developed double-hulled boats propelled by cranked paddlewheels placed between the hulls, and he engaged engineer William Symington to build his patent steam engine into a boat which was successfully tried out on Dalswinton Loch in 1788, and followed by a larger steamboat the next year. Miller then abandoned the project, but ten years later Symington was engaged by Lord Dundas, and in March 1802, Charlotte Dundas towed two 70 ton barges 30 km (19 miles) along the Forth and Clyde Canal to Glasgow. This vessel, the first tow boat, has been called the first practical steamboat, and the first to be followed by continuous development of steamboats.

Robert Fulton, built what he called the North River Steamboat (often mistakenly described as Clermont). In 1807, she began a regular passenger service between New York City and Albany, New York.

In 1815, Pierre Andriel crossed the English Channel aboard Élise, marking the first sea-going use of a steam ship.
