Launched as the pride of British shipbuilding and the largest vessel in the world, Olympic was more than 40 per cent larger than her nearest rivals: almost 900ft long and the first ship to exceed 40,000 tons. She was built for comfort rather than speed and equipped with an array of facilities, including Turkish and electric baths (one of the first ships to have them), a swimming pool, gymnasium, squash court, a la carte restaurant, large first-class staterooms and plush public rooms. Surviving from 1911 until 1935, she was a firm favourite with the travelling public carrying hundreds of thousands of fare-paying passengers and retained a style and opulence even into her twilight years. During the First World War, she carried more troops than any other comparable steamship and was the only passenger liner ever to sink an enemy submarine by ramming it. Overshadowed frequently by her sister ships Titanic and Britannic, Olympics history deserves more attention than it has received. She was evolutionary in design rather than revolutionary, but marked an ambition for the White Star Line to dominate the North Atlantic express route. Rivals immediately began trying to match her in size and luxury. The optimism that led to her conception was rewarded, whereas her doomed sisters never fulfilled their creators dreams. This revised and expanded edition of the critically acclaimed RMS Olympic: Titanics Sister uses new images and further original research to tell the story of this remarkable ship 80 years after her career ended.
