Royal Caribbean Group will not launch the Wonder of the Seas — its biggest ship yet — next spring as originally scheduled.

The Richard Fain-led owner of 62 ships has pushed back delivery of the 6,360-berth vessel due to coronavirus-related delays at France's Chantiers de l'Atlantique, according to an announcement on its China-focused website.

"Royal Caribbean had to delay the deployment of the Wonder of the Seas from a Chinese home port," the New York-listed company said.

"However, we look forward to the arrival of the Wonder of the Seas after the epidemic has been brought under control as soon as possible."

Royal Caribbean declined to comment further on the delay. The shipyard did not return calls.

The Miami-headquartered cruise giant said it has yet to determine when the Wonder of the Seas will sail, but VesselsValue data shows an unnamed 6,360-berth newbuilding at the French shipyard that is set to launch in 2023.

When it is launched, the Wonder of the Seas will surpass the 5,518-berth Symphony of the Seas (built 2018) as its largest active cruiseship in the world.

"Royal Caribbean has prepared three lines of defence for the health and safety of tourists and crew under the new normal of epidemic prevention, including source control of viruses, multiple monitoring on board, prevention and isolation measures and emergency plans in case of an outbreak," Royal Caribbean Cruises Asia chairman Zinan Liu said in a statement.

"We are fully prepared to show the public that Royal Caribbean Cruise is a safe place."

Odyssey of the Seas delivery also delayed

In early July, Meyer Werft delayed delivery of the 4,095-berth Odyssey of the Seas to Royal Caribbean to April 2021 from November 2020, due to Covid-19 and fires at the yard.

Rival Carnival Corp may delay launching as many as a dozen ships, having confirmed three newbuilding delays already.

Carnival's P&O Cruises UK has confirmed that a May 2020 delivery of the Iona from German yard Meyer Werft has been postponed, but a new arrival date has yet to be determined.

Likewise, Princess Cruises has pushed back a July 2020 delivery of the Enchanted Princess but has yet to say when it plans to accept that ship from Italian yard Fincantieri Monfalcone.

TradeWinds has reported that Carnival pushed back delivery of the 183,000-gt Mardi Gras from Germany's Meyer Turku by three months to February 2021.
