SS Great Eastern
She also had six masts (said to be named after the days of a week – Monday being the fore mast and Saturday the spanker mast), providing space for of sails (7 gaff and max. 9 (usually 4) square sails), rigged similar to a topsail schooner with a main gaff sail (fore-and-aft sail) on each mast, one "jib" on the fore mast and three square sails on masts no. 2 and no. 3 (Tuesday & Wednesday); for a time mast no. 4 was also fitted with three yards. In later years, some of the yards were removed. According to some sources she would have carried . This amount of canvas is obviously too much for seven fore-and-aft sails and max. 9 square sails. This (larger) figure of sail area lies only a few square metres below that the famous Flying P-Liner "Preußen" carried – with her five full-rigged masts of 30 square sails and a lot of stay sails. Setting sails turned out to be unusable at the same time as the paddles and screw were under steam, because the hot exhaust from the five (later four) funnels would set them on fire. Her maximum speed was 24 km/h (13 knots).
HMS Spiteful (1899)
Admiralty specifications in force at the time of her construction required that she should be able to steam at 30 knots, and from this she was one of a group of torpedo boat destroyers known informally as "30-knotters". "Spiteful"s propulsion was through two propellers, each driven by one of two triple expansion steam engines that were powered by four coal-fired Reed water tube boilers operated at 250 pounds per square inch (1,724 kilopascals) and could produce indicated horsepower (IHP). In ships of her type the boilers were installed in a line fore-and-aft and in pairs, so that in each pair the furnace doors faced each other: thus one group of stokers could tend two boilers simultaneously, and only two boiler rooms, also known as stokeholds, were required. In sea trials it was found that, when run at 29.9 knots, she consumed of coal per IHP per hour, which was considered low, and a speed of 30.371 knots was "easily maintained". At 13.05 knots it was found that her capacity of about 91 tons (92.5 tonnes) of coal, consumed at a rate of per IHP per hour, gave her a steaming range of about 4,000 nautical miles.
