The _Robert Bruce_ was the first steamer to trade between the Clyde and Liverpool.[24] She was followed by the _Sir William Wallace_. Both were built by the Scotts, and had engines of 60 nominal horse-power. They began service in the summer of 1819; and the record of the maiden voyage of the former, in August, 1819, showed that two and a-half hours were occupied in the run from Glasgow to Greenock, about 22 miles; and within 26 hours thereafter the vessel took on her pilot at the north-west lightship outside the Mersey Bar. The return voyage was equally satisfactory. To quote again from contemporary records, "the passengers, both out and home, were so highly gratified with the performance of this vessel and their treatment on board that they unanimously expressed their entire satisfaction with Captain Paterson's exertions to render them comfortable and happy, their conviction of the seaworthiness of the vessel, and their admiration of the powers of the engines, capable of propelling so large a body at the rate of 7 knots per hour, in the face of a strong north-northwest wind and high sea for at least two-thirds of the way from Liverpool, her rate thither being nearly 9 knots."[25] In 1820, the _Superb_, of 240 tons and 72 horse-power, followed the _Sir William Wallace_, and marked a still further improvement. She had a copper boiler, and in the three cabins sleeping accommodation was provided for sixty-two passengers. She was "the finest, largest, and most powerful steam vessel in Great Britain.[26] The average duration of the passage from the Clyde to Liverpool did not exceed 30 hours." The _Majestic_, also for the Clyde and Liverpool service, was built in 1821, and was 134 ft. 11 in. long between perpendiculars, 22 ft. 8 in. beam, and 14 ft. 5 in. depth, moulded. Her draught, 10 ft. 6 in. forward and 12 ft. aft, was too great for the upper reaches of the Clyde, and passengers were brought from Glasgow to Greenock in a tender. In her four cabins there was greatly-increased accommodation for the passengers. She was probably the first steamer with a sleeping apartment exclusively for ladies. The copper boiler worked at a pressure of 4 lb. per square inch, and the engines ran at 56 revolutions. The fares[27] to Liverpool in those days were £2 15s., as compared with 11s. to-day; of course, very much better accommodation is now provided. The _City of Glasgow_ was built in 1822 for the Liverpool service. This vessel, which cost £15,000, had a speed of over 10 knots, and was reputed the fastest afloat. Her length was 110 ft. 4 in., beam 22 ft. 4 in., and depth, moulded, 13 ft. She was arranged like the _Majestic_, and the two were long the most important vessels in the Clyde and Liverpool trade. She was subsequently bought by McIver, and inaugurated the competition with the Burns line, commenced in 1829.[28] The McIver and Burns lines were subsequently combined.
