When Britannia debuts in February 2015, it will be by far the biggest ship in the P&O Cruise fleet, coming in at 141,000 tons and carrying 3,611 passengers: some 25,000-tones larger than P&O's previous biggest ship, Azura.
It will also be the biggest ship ever built specifically for the U.K. market.
At present, few details are being released about what Britannia will feature, but expect it to take the most popular features of the rest of the fleet and either recreate or improve upon them.
What has been revealed thus far includes:
Purpose-built single cabins with balconies
A forward-facing Crow's Nest Bar
An 'enhanced' Glasshouse Bar -- which has proven very popular on other ships in the P&O fleet
The largest spa on the fleet.
For the first time a British design company, Richmond, is overseeing the whole of the design of the ship's interiors to incorporate P&O's 175 years of history, and using modern design touches to try and bring in new-to-cruise passengers.
Richmond has worked on a number of great British hotels, including The Langham, Mandarin Oriental Hyde Park, Intercontinental Hotel London, and Four Seasons Hampshire; as well as international hotels including Four Seasons Mauritius and Sandy Lane Barbados.
Britannia will sail out of the U.K. to the Atlantic islands and possibly the Caribbean, though final itineraries have not been confirmed yet.
