Cunard and Carnival Corp. have announced this morning that they have entered into agreement to build a new ship for the 177 year old line. The line currently sails 3 ships, Queen Mary 2, Queen Elizabeth and Queen Victoria. This as-yet-unnamed ship will be delivered by Fincantieri in 2022. That seems like a long ways away, but the orderbooks are jammed pack so this is the earliest that they can fit one in.
From the render it looks like it will be a heavily modified Pinnacle class vessel which is of course an evolution of the Vista class vessel. Looks like they are able to build these types taller. There’s a noticeable additional deck at the top as well as additional half decks at the forward part of the superstructure.
