That is pretty hard to calculate as the cruise lines are composed of older, samaller as well as new mega-ships.
To give you an idea:
- The Freedom of the Seas cost $800MM
- The Island Princess cost $500MM
- The Grand Princess cost $450MM
- Royal Caribbean Ordered a $1.24B Cruise Ship
- The Costa Atlantica is $400MM
- The Vision of the Seas cost $277MM
- The Pride of Hawaii cost $500MM
- The QM2 cost $1.3B
You get the picture .....
