to explosion and disaster. In Britain, the characteristic steamboats were smaller and slower but safer, with low-pressure boilers, and sturdy hulls and high bulwarks designed to survive the heavier seas of coastal and ocean traffic. The future of Atlantic Ocean steamships would unfold mostly in the British Isles.

      

      William Symington’s many frustrations had an apparent chilling effect on steamboat building in Great Britain. After he finally laid up his unwanted creation at Bainsford, nine years passed before another British steamboat was launched. The Comet, completed in the summer of 1812, became the first passenger steamer in Europe. Her planner and owner, Henry Bell, had been interested in steam navigation for over two decades. But his mercurial nature – his ‘restless volatile genius’, as a friendly biographer put it, ‘flying from one daring scheme to another’ – kept Bell pushing on to the next experiment before finishing his last one. It took him a long time to settle down and produce his first actual steamboat.

      Like Watt and Symington, Bell was a Scotsman, born in 1767 near Linlithgow, west of Edinburgh. He came from a family of millwrights and was trained as a mason, millwright and shipbuilder, with early stints in Glasgow and London. (‘I was not a self-taught engineer, as some of my friends have supposed,’ he later insisted.) Settled in Glasgow, he built houses and public works and started to focus intermittently on steamboats around 1800, after Watt’s patent expired. Bell tried to interest various patrons and governments but got no favourable responses. He hung around the Carron Works when the engine and machinery of the Charlotte Dundas were being constructed, to the point even of making himself a nuisance to the workmen. Later he repeatedly inspected Symington’s boat at Bainsford.

      When Bell became the owner of the Baths Hotel in the resort town of Helensburgh, on the Clyde some twenty miles west of Glasgow, he acquired the necessary practical goad that pushed him finally to build a steamboat – for bringing Glaswegian customers out to his hotel. The Clyde, as yet undredged, was then a winding, shallow stream, often filled with sandbanks. Sailing boats drawing only five feet still might be grounded for an hour or two; passengers would be obliged to run on deck from side to side, rocking the hull and loosening the keel from the sand. To reach Glasgow, at the river’s eastern and narrowest point, Bell’s steamboat for the Clyde had to be small.

      In the autumn of 1811 he contracted with John Wood, a shipbuilder in Port Glasgow, for a hull forty-two and a half feet long, eleven and a half feet wide, and five and a half feet deep, and a total capacity of only twenty-five tons. John Robertson of Glasgow, a builder of textile-mill machinery, made the engine: a cylinder eleven inches in diameter, stroke of sixteen inches, and four horsepower. Four small paddle wheels hung on the boat’s sides. Her smokestack at the bow doubled as the mast for a single square sail (as on an old Viking ship). The Comet was named not to suggest her speed but in tribute to Halley’s Comet, recently visible in the night sky. Launched in July 1812, she began her Glasgow to Helensburgh to Greenock service a month later. As she puffed along the river, local boys would run down to the water’s edge, expecting or hoping to see her blow up. She made the trip three times a week in each direction, covering the twenty-six miles to Greenock reliably in four hours, sometimes under three and a half – as fast as horse-drawn travel by land, and cheaper and much more comfortable than heavy, unsprung vehicles on bad roads. Within a year, four road coaches that had been taking passengers to Greenock stopped running for lack of business.

      This quick success provoked a productive steamboat competition. For some years before the Comet, Bell had worked on steam navigation designs with John Thomson, a Glasgow engineer. Thomson had made sketches of a boiler and machinery, and he expected to help Bell produce his steamboat. But Bell instead went ahead on his own, leaving Thomson angry and disappointed. He took his revenge by building a bigger, faster boat, the Elizabeth. Also constructed by John Wood, she was fifty-nine feet long by twelve feet wide, and forty tons, with a nine-horsepower engine. Her cabin included such touches of luxury as carpets and a sofa, windows with tasselled curtains and velvet cornices, and even a small shelf of books. The Elizabeth ran from Glasgow to Greenock and back every day, instead of only thrice weekly, carrying as many as one hundred passengers at speeds up to nine miles an hour, cutting steadily into Henry Bell’s business.

      Over the next few years, steamboats appeared on most of the major rivers of Great Britain. Just before the first railroads, they started to speed and discipline the pace of life, ratcheting up to the predictable, rationalized clock time of the Industrial Revolution. Steamboats ran at man’s pleasure, ploughing along through adverse winds and waves, coming and going as ordered. A clock soon became a necessary instrument for doing business. ‘The merchant, knowing the time of the tide, can count to an hour, in ordinary weather, when his goods will arrive; and will not be disappointed in one case out of thirty’ Henry Bell asserted. ‘I expect in a short time to see all our ferries, and our coasting trade carried on by the aid of steam-vessels.’

      In May 1815, the first long ocean passage by a steamboat in Europe tested steam’s potential for that coasting trade. The Glasgow (later renamed the Thames) had been built by John Wood a year earlier. She showed steady progress in size and power: seventy-two feet long by fifteen feet wide, sixteen horsepower, and seventy-four tons. Sold to London interests for service on the Thames, she put to sea just for delivery to her new owners, not to start a regular ocean service between Scotland and England. Under the command of George Dodd, a young architect and civil engineer, she set forth from Glasgow with an eight-man crew of a master, four sailors, and a cabin boy – and a smith and fireman for the engine.

      The Glasgow ran easily down the Firth of Clyde into the narrow channel between Scotland and Ireland. Here she encountered more difficult sailing than anything normally seen on the Clyde, as the ebb tide collided with strong swells sweeping in from the North Atlantic. Unable to make progress, Captain Dodd had to seek shelter in Loch Ryan. The Glasgow ventured out again, was tossed around, and nearly wrecked on the rocky Irish coast. She stopped at Dublin for several days of rest and repairs. Naval officers came to see her, agreeing that she would probably not survive a true stormy sea and had better hug the shore. Watched by thousands of spectators ranged along her way, she left Ireland with just two brave passengers for London.

      Away from the coast in the Irish Sea, she again met heavy swells. ‘The movement of the vessel differed entirely from that of one pushed by sails or oars,’ noted Isaac Weld, one of the passengers. ‘The action of the wheels upon the water on both sides, prevented rolling; the vessel floated on the summit of the waves, like a sea-bird. The most disagreeable movement took place when the waves struck the ship crossways; but here too its particular construction gave it a great advantage; for the cages which contained the wheels acted like so many buoys.’ As water flooded into the paddle box on the windward side, the compressed air exploded in an alarming report whose percussive force made the whole boat tremble. This noise exploded again, by reaction, on the other side of the Glasgow, then again, much diminished, on the first side. At this point she at least stopped rolling for a while. ‘During the rest of the voyage,’ according to Weld, ‘the vessel made what the sailors call, a dry way, that is, it danced so lightly over the waves, that it never took in one; and in all the passage we were not once wet…which could not be expected in any common ship.’

      As they neared Wexford, at the southeastern corner of Ireland, the Glasgow’s thick coal smoke convinced local pilots that the approaching boat was on fire. They scrambled out to sea, expecting to save lives and perhaps seize some profitable salvage – and were surprised and disappointed that the Glasgow was just steaming along in safety. She crossed St George’s Channel to England, near Cape St David, and was again greeted by a flotilla of would-be rescuers not anticipating a smoking steamboat in those waters. Heavy seas tossed up waves so high
