The ship was to have been the first -long ocean liner.

Document 7: SS Cymric: SS "Cymric" was a steamship of the White Star Line built by Harland and Wolff in Belfast and launched on 12 October 1897. She had originally been designed as a combination passenger liner and livestock carrier, with accommodations for only First Class passengers. During the stages of her design layout, it became clearer to the designers at Harland and Wolff that combining passengers and livestock had become rather unpopular, so the spaces designated for cattle were reconfigured into Third Class accommodations. She departed Liverpool on her maiden voyage on 29 April 1898, arriving in New York City on 9 May 1898. She spent the first five years of her career on the White Star Line's main passenger service route between Liverpool and New York, until 1903 when she was transferred to the less traveled Liverpool-Boston route, which she sailed on for nine years before being returned to the New York route in 1912.

With the retirement of Queen Elizabeth 2 in 2008, Queen Mary 2 is the only transatlantic ocean liner in line service between Southampton, England, and New York City, United States, operating for a part of each year. The ship is also used for cruising, including an annual world cruise.She was designed by a team of British naval architects led by Stephen Payne, and was constructed in France by Chantiers de l'Atlantique. At the time of her construction, Queen Mary 2 held the distinctions of being the longest, at 1,131.99 ft (345.03 m), and largest, with a gross tonnage of 148,528 GT, passenger ship ever built.
