At 362 meters long, 66 meters wide and 70 meters high, Royal Caribbean’s new 228,081 GRT cruise ship takes the “world’s largest” title.

Mega ship Symphony of the Seas was delivered today to owner Royal Caribbean International from French shipbuilder STX France who has been constructing the vessel since 2015.

The new cruise liner, which boasts 18 decks total with capacity for 6,800 passengers in 2,747 staterooms and is crewed by more than 2,000 staff members, takes the size crown from her slightly smaller sister vessel, Harmony of the Seas.

The delivery comes barely two years after the delivery Harmony of the Seas, and will be followed by another of her class due in 2021.

“The Oasis Class has been a trend-setting design, but the team has evolved the design to build on that success to provide even more incredible family adventures,” said Royal Caribbean Cruises Ltd. Chairman and CEO, Richard D. Fain. She is now the largest cruise ship ever and she’s leaving Saint-Nazaire’s yard after reaching outstanding finishing levels,” said STX France Chief Executive, Laurent Castaing.

Among the ship’s notable features are a 10-deck-tall slide, a zipline, laser tag, a large selection of dining options and Broadway musicals. She is also the first cruise ship to be granted with the “SILENT-E” class from DNV-GL for her low level of underwater noise.

Symphony of the Seas will debut in Barcelona, Spain and spend her inaugural summer season sailing the Mediterranean before heading to the Caribbean.
