Each new record-holder has pushed the envelope, setting new standards for what a cruise ship can be.

From Ocean Liners to Floating Resorts

In the early 1900s, ships like the RMS Olympic (1911) and RMS Queen Mary (1936) were considered engineering marvels. These vessels were designed for transatlantic travel, emphasizing speed and durability over leisure. However, by the 1970s, the rise of commercial air travel diminished the need for long-haul ocean crossings, forcing cruise lines to pivot. The focus shifted from transportation to vacation experiences, leading to the birth of the modern cruise ship.

One of the first true mega-ships was Norwegian Cruise Line’s Norwegian Epic (2010), which introduced large-scale entertainment venues and innovative cabin designs. But it was Royal Caribbean that truly revolutionized the industry with its Freedom-class ships (2006–2008), including Freedom of the Seas, which was the first to exceed 160,000 gross tons. This marked the beginning of the “arms race” for size.

Breaking Records: The Oasis-Class Dominance

The real turning point came with the launch of Oasis of the Seas in 2009. At 225,282 gross tons, it shattered previous records and introduced the concept of a “floating city.” With seven distinct neighborhoods, an open-air Central Park with real trees, and the world’s first zip line at sea, Oasis of the Seas redefined luxury cruising.

• Oasis of the Seas (2009) – 225,282 GT
• Allure of the Seas (2010) – 225,282 GT (sister ship)
• Harmony of the Seas (2016) – 226,963 GT (slightly larger)
• Symphony of the Seas (2018) – 228,081 GT
• Wonder of the Seas (2022) – 236,857 GT

Each new Oasis-class ship added more amenities, larger pools, and enhanced technology. For over a decade, these vessels held the title of the world’s largest cruise ships, setting a benchmark that seemed unbreakable—until now.
