World`s largest cruise liner

The Allure of the Seas cruise ship, belonging to Royal Caribbean International, is nearly a twin  sister of “Oasis of the Seas” cruise liner. The difference is that the later is 5 cm shorter that the prior despite that both of them were built to the same specifications at the same shipyard. This 5 cm difference is permissible at such size as it might simply occur due to, say, temperature of metal during construction.  The gross weight of Allure of the Seas cruise ship is 225 282 GT and her length is 362 m.
