Royal Caribbean's liner Wonder of the Seas was delivered by Chantiers de l'Atlantique Shipyard (St Nazaire, France).
The vessel is currently the world's largest cruise ship by GT tonnage/volume (236857 tons) and is currently en route to Port de Marseille Fos (France) where will receive the last works to her construction.
The newbuild is from the Oasis Plus class and has the maiden voyage scheduled for March 4, 2022, as part of the Caribbean mini-season from homeport Fort Lauderdale/Port Everglades (Florida USA). Wonder OTS will then be deployed in Europe for Western Mediterranean voyages out of homeports Barcelona (Spain) and Civitavecchia-Rome (Italy) - starting May 8, 2022.
Wonder OTS is Royal Caribbean Group's 5th Oasis-class liner (ordered in December 2016), with sisterships Harmony, Oasis, Allure and Symphony. These are currently the world's biggest passenger liners ever constructed. RCG planned ship's cost per berth to be lower compared to Allure and Oasis. Like the sisterships, Wonder OTS has telescoping funnels to be able to sail under bridges. Unlike the original/smaller Oasis-class ships, Wonder has no Wonderland Imaginative Cuisine (specialty restaurant) and 150 Central Park (dinner-only specialty restaurant), while the adult-only Solarium complex has a swimming pool and 2 additional whirlpools.
The vessel has a building cost of USD 1,35 billion (2019 shiporder rates).
In comparison to the other sisterships, Oasis-Plus Class boats are heavier, wider, and with bigger passenger capacity. Wonder is nearly 330 ft (101 m) longer than RMS Titanic and 165 ft (50 m) longer than Eiffel Tower (Paris City). The liner has several promenades, 2x FlowRiders, 2x Rock-Climbing Walls, an Ice-Skating Rink, world's largest theatre at sea.
