It was loosely based upon the design of the original Earth sea-going vessel RMS Titanic. This was primarily a tourist vessel and it is unclear whether Max Capricorn, the owner, was aware of the name's significance: the Doctor himself noted that it was a very bad for a ship. The ship had a humanoid crew, supplemented by a contingent of information and service robots called Hosts, who offered assistance and advice to the passengers. Like the ill-fated vessel that sank in 1912, this ship met with a horrific accident.
