Royal Princess

Operated by Princess Cruises, the Royal Princess was delivered in June 2013 by the Fincantieri shipyard.  At 330m in length she can carry up to 3,600 passengers.  By contrast the Maid of The Forth at her bow can accommodate 225 passengers on trips around the islands and bridges of the Firth.
 
If you look closely at the top of the ship you can make out the giant TV screen for the passengers on deck.
