Oasis of the Seas

Oasis of the Seas is a cruise ship operated by Royal Caribbean International. She is the first of her class, the Oasis class, whose ships were the largest passenger ships in the world, until surpassed in 2023 by the Icon class. Her hull was laid down in November 2007 and she was completed and delivered to Royal Caribbean in October 2009. At the time of construction, Oasis of the Seas set a new capacity record of carrying over 6,000 passengers. The first of her class, she was joined by sister ships Allure of the Seas in December 2010, Harmony of the Seas in May 2016, Symphony of the Seas in April 2018, and Wonder of the Seas in March 2022, as well as Utopia of the Seas in July 2024. As of November 2024, Oasis of the Seas conducts cruises in the Caribbean from her home port of Port Everglades in Fort Lauderdale, Florida.

Oasis of the Seas surpassed the Freedom-class cruise ships (also owned by Royal Caribbean) to become the largest cruise ship in the world at that time. She was herself surpassed by her sister ship Allure of the Seas, which is 50 millimetres (2.0 in) longer, although this may have been caused by ambient temperature differences at the times the measurements were made. In May 2016, her second sister ship Harmony of the Seas became the new record holder with a length of 362.12 metres (1,188.1 ft), and in March 2018, Symphony of the Seas, the fourth member of the Oasis class, became the new world's largest cruise ship with a length of 361.011 m (1,184.42 ft) and a tonnage of 228,081 GT.
