P&O Cruises had a ship named P&O Auroa that was plagued with all kinds of problems from the get-go as it blew a main drive shaft on its inaugural cruise. That was the beginning of a long history of trouble the ship encountered. It first sailed in 2000, so it might have been a candidate to be sold to a smaller cruise line to be operated as a day gambling boat. Wikpedia -- has a lot of information about the history of ship.
