The azipod driven excel class should be far more manoeverable than the older twin propeller ones, which is standard on all other P&O ships, except for Arcadia.
What would be interesting is to compare missed ports due to high winds on all the excel class ships, Aida, Costa and Carnival, with P&O, to see if they all suffer from the same problem, or are P&O deck officers more cautious when playing with their new toys?
