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).
Spiteful-class destroyer
Concern about the higher speeds of foreign boats had prompted the Admiralty to order new destroyers capable of 30 knots, rather than the 27 knot requirement which had been standard. The boats were not able to make this speed in bad weather, where they were usually wet and uncomfortable with cramped crew quarters. However, they proved their toughness while serving through the Great War, despite being twenty years old. Thanks to their watertight bulkheads, their thin plating and light structure was able to take a great deal of damage and remain afloat; although their plates were easily damaged by rough handling or heavy weather.
