Move over Oasis of the Seas and Allure of the Seas. You're no longer the world's largest cruise ships. Royal Caribbean Cruise Line launched the Harmony of the Seas in May 2016, and this new ship is seven feet longer than its two older sister ships that were launched in 2009 and 2010, respectively. The Harmony of the Seas also has 2 more passenger decks, 43 more cabins, and can carry up to 5,479 guests (double occupancy) compared to the 5,408 on Oasis and Allure. The massive ship can pack up to 6,780 guests when all the berths are full.

Harmony of the Seas is the 25th ship in the Royal Caribbean fleet. Royal Caribbean also launched the new Ovation of the Seas, a sister ship to Quantum of the Seas and Anthem of the Seas, in May 2016.
