Currently the largest cruise ship in the world is the Symphony of the Sea cruise ship.
The Symphony of the Sea Cruise Ship is the largest cruise ship in the world.
It's the 25th ship in Royal Caribbean's fleet and is considered to be a giant cruise ship when it comes to cruise ships and has 228,081 gross registered tons, measures 238 feet tall and spans 1,188 feet long.
There are many more larger ships than the largest cruise ship as in cargo ships but as of now the largest cruise ship is the Symphony of the Sea.
It would be very interesting if another larger cruise ship came in the future which is possible.
