Carnival Cruise Line has revealed a cruiseship newbuilding boasting the world’s first sea-going rollercoaster and another vessel undergoing an extensive refit have both been delayed until 2021.

The cruise line, which is the flagship company of Carnival Corp, has attributed this to shipyard disruptions caused by the Covid-19 pandemic.

It said the delivery of its new flagship — the 183,000-gt, LNG-powered Mardi Gras — has been pushed back to 30 January 2021.
