Top 5 Biggest Cruise Ships
5 Largest Cruise Ships in The World 2024
Updated 1 December 2024
Are you wondering which is currently the biggest/largest cruise ship in the world? Often when people think of cruise ships, particularly if they have never cruised, they have a romantic idea of the elegant Ocean Liners of the past. However, most liners were much smaller even than today’s mid-sized cruise ships at less than 50,000 gt.
One of the few liners in service today is Cunard’s Queen Mary 2, and at 149,215 GT she is the exception to the rule.
When we took our first cruise it was on P&O Cruises Aurora, which at just over 76,000 GT seemed absolutely huge to us. Things have moved on significantly and each class of ship seems to get much larger than the previous one.
With that in mind, at the risk of this post not aging well as newer and bigger ships are built, let’s take a look at five of the largest cruise ships currently in service. Interestingly, all five are operated by Royal Caribbean International - and that doesn’t seem to be about to change anytime soon.
