Comparison of fleet mates

Without question the most iconic and authentic ships of the modern P&O Cruises fleet are ORIANA and near sister AURORA.
As is well known amongst fans of these remarkable ships AURORA was initially  designed to be a sister to ORIANA featuring more of the formers signature features including the CANBERRA inspired funnel and arrangement of the upper forward decks.
Many of the changes to the design was made by Swedish designer Anders Johansson who was approached by P&O to contribute towards the design it was his intention to create a more 'streamlined' ship.
