The passenger — and her cabin partner — are banned for life for posing outside the railing of the 61-deck Allure of the Seas.
A woman has been branded a «moron» for balancing on the edge of the world’s second largest cruise ship to take a selfie.
The passenger was pictured posing in a swimsuit on a small platform on the outside edge of the Allure of the Seas ship in the Caribbean as part of a seven-day cruise from Fort Lauderdale in Florida.
Royal Caribbean, who runs the cruise, made her get off the ship at the next port and has banned her for life from its trips.
Fellow passenger Peter Blosic took a photo of the woman on one of the ship’s 16 decks and posted it on Facebook, calling her an «absolute idiot».
He added: «You cannot fall off of a ship unless you are acting like a moron!»
The passenger said he notified the ship’s guest services and the woman, and the person she was sharing a cabin with, were made to leave the cruise in Jamaica.
Royal Caribbean, who runs the cruise, confirmed the woman and her companion have been banned for life from sailing with them.
«Earlier this week on the Allure of the Seas a guest was observed recklessly and dangerously posing for a photo by standing on her stateroom balcony railing with the help of her companion,» the company said in a statement to USA Today.
«Security was notified and the guests were later debarked in Falmouth, Jamaica, as a result of their actions and are now banned for life from sailing with Royal Caribbean.»
According to Royal Caribbean’s guest conduct policy, passengers are prohibited from «sitting, standing, laying or climbing on, over or across any exterior or interior railings or other protective barriers, or tampering with ship’s equipment, facilities or systems».
Failure to comply could result in «law enforcement» or «removal from a ship at the next port of call».
The Allure of the Seas was the largest passenger ship in service when she was launched in 2009 but was overtaken by her sister ship, Harmony of the Seas, in 2015.
She can carry 6,296 passengers and 2,384 crew, and features a two-deck dance hall, a 1,380-seat theatre, an ice skating rink and 25 dining areas.
A seven-day cruise of the Caribbean on the ship costs about £800 for a balcony room, stopping at four ports.
