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).

The four s were commenced between October 1911 and May 1912 and entered service in 1914 at a cost of 45 million marks, forming the other part of the Third Squadron of the High Seas Fleet. They were 28,500 tons, with a maximum speed of 21 knots from three triple-stage Brown-Boverie-Parsons turbines. Main armament was five double turrets housing twin 30.5 cm guns, arranged with two turrets fore and aft and one in the centre of the ship. The second turret at either end was raised higher than the outer so that it could fire over the top (superfiring). As with "Prinzregent Luitpold", the ships were originally intended to have one diesel engine for cruising, but these were never developed and turbines were fitted instead. The ships were equipped with torpedo nets, trailed along the hull intended to stop torpedoes, but these reduced maximum speed to an impractical 8 knots and were later removed.
