MS Oasis of the Seas is an , delivered to her owner, Royal Caribbean International, in October 2009. The first of her class, she was joined by her sister ship in December 2010. Both vessels cruise the Caribbean from Port Everglades in Fort Lauderdale, Florida. She set a new record of carrying over 6,000 passengers. The ship surpassed the cruise ships (also owned by Royal Caribbean) to become the largest cruise ship in the world at that time. She has, however, since been surpassed by Allure of the Seas, which is longer, although this difference may have been caused by different temperatures when the measurements were made.
