An  order for a 141,000 gross ton cruise liner that P&O Cruises, which is part of the Carnival Corp & plc group, placed in June with Fincantieri, the Italian shipbuilder includes an option for a second ship, Fincantieri said in a statement.

P&O Cruises, which on 1 June unveiled the news that it had ordered its largest ship so far, did not mention anything about an option for a second ship. However, most shipbuilding contracts do include one or more options for further vessels.

P&O Cruises have not so far either taken up or axed the option. The  ship ordered in June will be delivered in 2015 and it will be a sister vessel to two similar sized vessels the Italian yard is building for P&O Cruises’ sister company Princess Cruises.
