They were each 330 feet between perpendiculars, 39 feet 1 inch beam, 15 feet 2 inches depth of hold, with a gross tonnage of 1557. The engines of each were of 925 nominal horse-power, and of 6500 indicated, and their average speed was 20¹⁄₂ knots. Both these were paddle-vessels. The third _Tynwald_ was launched in 1891, and is a twin-screw ship. The _Empress Queen_, the biggest paddle-steamer the company ever possessed, was ordered in 1896 from the Fairfield Company. She is 360 feet 1 inch between perpendiculars, 42 feet 3 inches beam, and 17 feet depth of hold. Her gross tonnage is 2140; her engines, of 1290 nominal horse-power and 10,000 indicated, gave her then a speed of 21¹⁄₂ knots, which has since sometimes been exceeded. The third _Douglas_ and the third _Mona_ call for no special comment, except that the former was the _Dora_ of the London and South-Western Railway, from which the Manx Company purchased her in 1901, and that the last-named steamer was the last paddle-boat ordered by the company. The directors in 1905, finding the need of newer and faster vessels, ordered the steamer _Viking_, propelled by triple screws driven by turbine machinery, and so successful was she that the third _Ben-my-Chree_ was added in 1908. It may be questioned if any other of the coasting companies presents in its vessels such an illustration of the development of steam-ships and steam-engines, from the insignificant little tubs no bigger than river barges to the latest examples of the shipbuilder’s art.
