Ocean Steamships A popular account of their construction, development, management and appliances — A Reader’s Guide

tons; New York had 77, of which 39 were of a large class, exceeding generally 300 tons—the largest was the President, of 615 tons, built in 1829. Liverpool had at this date 41 steamers; the largest was of 559 tons, 4 others exceeded 200 tons, and all the others were much smaller. London had 169, of which the largest was the British Queen, just built, of 1,053 tons; the next largest was of 497 tons. Glasgow and Belfast had been in regular steam communication since 1818; Glasgow and Liverpool, London and Leith, since 1822. The first ferry-boat on the Mersey, it may be noted, the Etna, 63 feet long, with a paddle-wheel in the centre, began her trips in 1816.

In 1819 the Atlantic was first crossed by a ship using steam. This was the Savannah, of 380 tons, launched at Corlear’s Hook, New York, August 22, 1818.[2]

She was built to ply between New York and Savannah as a sailing-packet. She was, however, purchased by Savannah merchants and fitted with steam machinery, the paddle-wheels being constructed to fold up and be laid upon the deck when not in use, her shaft also having a joint for that purpose. She left Savannah on the 26th of May, and reached Liverpool in 25 days, using steam 18 days. The log-book, still preserved, notes several times taking the wheels in on deck in thirty minutes.

In August she left Liverpool for Cronstadt. An effort was made to sell her to Russia, which failed. She sailed for Savannah, touching at Copenhagen and Arendal, and arrived in 53 days. Her machinery later was taken out, and she resumed her original character as a sailing-packet, and ended her days by being wrecked on the south coast of Long Island.

But steam-power had by 1830 grown large enough to strike out more boldly. The Savannah’s effort was an attempt in which steam was only an auxiliary, and one, too, of a not very powerful kind. Our coastwise steamers, as well as those employed in Great Britain, as also the voyage of the Enterprise to Calcutta in 1825 (though she took 113 days in doing it), had settled the possibility of the use of steam at sea, and the question had now become whether a ship could be built to cross the Atlantic depending entirely on her steam power. It had become wholly a question of fuel consumption. The Savannah, it may be said, used pitch-pine on her outward voyage, and wood was for a very long time the chief fuel for steaming purposes in America. How very important this question was will be understood when it is known that Mr. McGregor Laird, the founder of the Birkenhead firm, in 1834, laid before the Committee of the House of Commons on Steam Navigation to India the following estimate of coal consumption:

Under 120 horse-power, 10-1/2 lbs. per horse-power. 160 „ 9-1/2 „ „ 200 „ 8-1/2 „ „ 240 „ 8 „ „

Or more than four times what is consumed to-day in moderately economical ships. In other words, to steam at her present rate across the Atlantic the City of New York, of 18,000 horse-power, would need to start with something like 7,500 tons of coal on board were her consumption per indicated horse-power equal to that of the best sea practice of that date, which could hardly have been under 6 pounds per indicated horse-power per hour.

This may be said to have been the status of affairs when, in 1836, under the influence of Brunei’s bold genius, the Great Western Steamship Company was founded as an off-shoot of the Great Western Railway, whose terminus was then Bristol. Brunel wished to know why the line should not extend itself to New York, and the result of his suggestion was the formation of the steamship company and the laying down at Bristol of their first ship, the Great Western.

Brunel’s large ideas were shown in this ship, though in comparatively a less degree, as well as in his later ones. She was of unprecedented size, determined on by Brunel as being necessary for the requisite power and coal-carrying capacity. The following were her principal dimensions: Length over all, 236 ft.; length between perpendiculars, 212 ft.; length of keel, 205 ft.; breadth, 35 ft. 4 in.; depth of hold, 23 ft. 2 in.; draught of water, 16 ft. 8 in.; length of engine-room, 72 ft.; tonnage by measurement, 1,340 tons; displacement at load-draught, 2,300 tons.

Dimensions of engines: Diameter of cylinders, 73-1/2 in.; length of stroke, 7 ft.; weight of engines, wheels, etc., 310 tons; number of boilers, 4; weight of boilers, 90 tons; weight of water in boilers, 80 tons; diameter of wheel, 28 ft. 9 in.; width of floats, 10 ft.
