With cruise lines building larger cruise ships every year, the list of the top 10 largest cruise ships in the world is constantly changing. In the past 12 months, two new ships have joined the list. Out of the top 10 largest cruise ships, all 10 are from Royal Caribbean and Norwegian Cruise Line.
Cruise ships are measured by gross tonnage which is a figure calculated from the total enclosed volume of the ship. For a good comparison of how large today’s cruise ships are, the Titanic was an estimated 46,000 gross tons in size.
1. Harmony of the Seas: The largest cruise ship in the world made her debut this past week and comes in at 226,963 gross tons. Royal Caribbean’s newest ship carries up to 6,360 passengers in 2,747 staterooms and is one foot longer than her sister ships, Allure of the Seas and Oasis of the Seas.
2. Allure of the Seas: The 2nd largest cruise ship in the world is Royal Caribbean’s Allure of the Seas coming in at 225,282 gross tons. Allure went into service in 2010 and held the title as world’s biggest ship until this past week. The ship is 1,187 feet long and is able to hold over 6,000 passengers.
3. Oasis of the Seas: The 3rd largest cruise ship in the world is the Oasis of the Seas, the sister ship to the Allure. Although the Oasis is technically the same size as the Allure, the Allure is a couple inches longer.
4-6. Quantum of the Seas/Anthem of the Seas/Ovation of the Seas: Quantum of the Seas, Anthem of the Seas, and Ovation of the Seas are the most technologically advanced cruise ships ever built and come in at 168,000 gross tons in size. Features included on the Quantum class ships include virtual balconies on all inside staterooms, robotic bartenders, a wave pool, and a skydiving simulator.
