Due to their increased size the Olympic-class liners could offer many more amenities than Lusitania and Mauretania. Both Olympic and Titanic offered swimming pools, Turkish baths, a gymnasium, a squash court, large reception rooms, À la Carte restaurants separate from the dining saloons, and many more staterooms with private bathroom facilities than their two Cunard rivals.
Heavy vibrations as a by-product of the four steam turbines on Lusitania and Mauretania would plague both ships throughout their careers. When Lusitania sailed at top speed the resultant vibrations were so severe that second- and third-class sections of the ship could become uninhabitable. In contrast, the Olympic-class liners utilised two traditional reciprocating engines and only one turbine for the central propeller, which greatly reduced vibration. Because of their greater tonnage and wider beam, the Olympic-class liners were also more stable at sea and less prone to rolling. Lusitania and Mauretania both featured straight prows in contrast to the angled prows of the Olympic liners. Designed so that the ships could plunge through a wave rather than crest it, the unforeseen consequence was that the Cunard liners would pitch forward alarmingly, even in calm weather, allowing huge waves to splash the bow and forward part of the superstructure. The vessels of the Olympic class also differed from Lusitania and Mauretania in the way in which they were compartmented below the waterline. The White Star vessels were divided by transverse watertight bulkheads. While Lusitania also had transverse bulkheads, it also had longitudinal bulkheads running along the ship on each side, between the boiler and engine rooms and the coal bunkers on the outside of the vessel. The British commission that had investigated the sinking of Titanic in 1912 heard testimony on the flooding of coal bunkers lying outside longitudinal bulkheads. Being of considerable length, when flooded, these could increase the ship's list and "make the lowering of the boats on the other side impracticable" — and this was precisely what later happened with Lusitania. The ship's stability was insufficient for the bulkhead arrangement used: flooding of only three coal bunkers on one side could result in negative metacentric height. On the other hand, Titanic was given ample stability and sank with only a few degrees list, the design being such that there was very little risk of unequal flooding and possible capsize.
