Royal International Caribbean’s Allure of the Seas nabs the top spot for the largest cruise ship in the world – perhaps it should be called Whale of the Seas instead! The ships beats out her sister Oasis of the Seas by just two inches, making Allure technically the world’s biggest cruise ship, even though the two have the same technical specifications and were constructed at the same time. Allure is just over 1,187 feet long (360 m). That’s nearly four football fields.

Builders in the shipyard say that it’s not uncommon to come up with small differences in ships so big — differences in length may occur simply due to the temperature of the steel in a ship as big as this.
