Hi I think the media are confused by the Gross tonnage which is now used to describe new cruise ships. True displacement i.e. weight of materials that makes up the ship is closer to 70,000 tons if that.
And many have aluminium s/s's anyway. So saying 132,000 tons of steel is grossly inaccurate.
Gross tons is a messurement of useable volume, which is why most of them look so awful compared to the grace of the old 'liners'. But the extra volume makes the ship more financially viable.
Few of the current cruise ships would want to cross the N. Atlantic during the winter. The Queen Victoria was strengthened to do so but has a relatively low top speed and a somewhat bluff bow and, I read, was most uncomfortable in the crossing a year or so back.
