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 Furious (47)
"Furious" had an overall length of , a beam of , and a draught of at deep load. She displaced normally and at deep load. She had a metacentric height of at deep load. "Furious" and her half-sisters were the first large warships in the Royal Navy to have geared steam turbines. To save design time the installation used in the light cruiser , the first cruiser in the RN with geared turbines, was copied and simply duplicated to provide two sets of turbines. The four Brown-Curtis turbines were powered by eighteen Yarrow small-tube boilers that were designed to produce a total of . The ship's speed was an estimated , but she never ran her sea trials.
