Stephen Payne (naval architect) in the context of "Queen Mary 2"

RMS Queen Mary 2 (QM2) is a British ocean liner. She has served as the flagship of the Cunard Line since April 2004, and as of 2025, is the only active, purpose-built ocean liner still in service. Queen Mary 2 sails regular transatlantic crossings between Southampton and New York City, in addition to short cruises and an annual world voyage.

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 was the longest, at 1,131.99 ft (345.03 m), and largest, with a gross tonnage of 148,528 GT, passenger ship ever built. She no longer holds these records after the construction of Royal Caribbean International's 154,407 GT Freedom of the Seas (a cruise ship) in April 2006, but remains the largest ocean liner ever built.
