All 7 P&O Ships Visit Southampton
P&O Cruises can trace its roots back to 1837 and this year is celebrating 175 years of heritage - so the company brought all seven of its ships to Southampton for the first time.
Thousands of people lined the shore on Tuesday July the 3rd to see she ships which were carrying 15,000 passengers and 6,000 crew between them.
The seven ships, Adonia, Arcadia, Aurora, Azura, Oceana, Oriana and Ventura - sailed into Southampton early in the morning - the first time they have gathered together in their home port.
Princess Anne reviewed the fleet and on Azura, ballerina Darcey Bussell, who named the ship in 2010, was presented with seven captain's hats. Unfortunately a Red Arrows display at 7.20pm had to be cancelled because of the weather, and the flypast at 11.45am was called off as well.
In the evening, all the ships left in convoy.
Adonia left her berth at 5.15, and led the procession at 6.25. Bringing up the rear, Oceana left at 6.55.
P&O Cruises managing director, Carol Marlow, said:
"This day is one of the most significant days in our history, as all our seven ships gather in their home port on the same day for the first time ever.
"As we look forward to exciting plans for our next new ship in 2015, it is fitting to be celebrating our past as it has helped us become known as Britain’s trusted cruise experts.”
The ships formed a procession as they left Southampton and headed down the Solent. Where the channel widens, the ships moved into a formation to be photographed from the air then sailed onwards to their various destinations.
The busy road's being made two lanes in both directions between Segensworth and Titchfield - it's due to take 18 months.
