Royal Caribbean International’s Anthem of the Seas will be “no competition” for P&O Cruises’ Britannia, according to Carnival Corporation boss Arnold Donald.

Donald said there was no competition between the two, which will both be based in the UK this year, because the ships are targeting very different target markets and demographics.

Speaking during a press conference for the launch of Britannia in Southampton on Monday, a day ahead of the ship being named by the Queen, Donald said: “They are two very different ships for two very different types of people.

“People may experiment with both. There is no competition – Britannia is for the British public, Anthem is not that.

“Britannia has its Food Heroes and lots of venues for entertaining and dining on board.

“We welcome them into the frame.”

David Dingle, chairman of Carnival UK, said he believed the two vessels could “co-exist happily together”.

He added: “Comparing this ship with Royal Caribbean’s ship is great because the two are completely different.

“They can co-exist happily together. They will not directly compete with each other and that’s good because it helps to raise the cruise market.”
