Why the ship didn't hit the span
Like its sister, Oasis of the Seas, with which it shares the title of worlds's largest cruise ship, the Allure of the Seas had to kinda limbo to get under Denmark's Storbelt (Great Belt) bridge.
Reading some of the press coverage you might think that the giant cruise ship had actually scraped the bridge.
Here's one example of the coverage the effort earned:
"A Royal Caribbean European cruise ship barely escaped what could have been an unfortunate accident Saturday, narrowly avoiding a bridge in Denmark by mere inches."
The Royal Caribbean cruise ship Allure of the Seas barely made it under Denmark's Storebelt Bridge on Saturday. The crew and passengers applauded as the ship finally cleared the bridge with barely a foot to spare.Of course, the giant Royal Caribbean ship was designed to safely pass under the bridge on its passage from STX Finland to its homeport in Fort Lauderdale, Fla.
A Royal Caribbean video clip explains how you get a ship that normally has a height above the waterline of about 73 meters (240 feet) under a bridge offering a clearance of 65 m (213 ft).
