Recognized as the first British company to operate regular sea cruises, P&O has a history that goes back to 1837. In more recent times, P&O has undertaken a shift away from line voyages to operating cruises full time. The purchase of Princess Cruises in 1973 led to the founding of the company as it is today. Here, Roger Cartwright tells the story of P&O Princess's illustrious history as a cruise line, from the Vectis, the world's first dedicated cruise ship, to the Grand class ships of today, each carrying almost 3,000 passengers and weighing in at more than 115,000 tons each--and let's not forget the stint in the 1970s as Aaron Spelling's Love Boat. Packed with previously unpublished photographs, this guide includes a complete list of all the ships to have sailed for P&O.
