Multiple sources reported that Royal Caribbean’s Allure of the Seas, the world’s largest cruise vessel, has encountered difficulties with its propulsion system, impeding full speed capabilities. The ship is reported to be functional, but sailing at reduced speeds.

Because of the propulsion issue, the 1,187-foot vessel and its passengers of the ship’s past two Eastern Caribbean sailings were forced to experience shorter port calls to compensate for longer sailing times.

USA Today reported that Royal Caribbean is currently looking into the issue and searching for means to fix it. Royal Caribbean has not said when the issue will be resolved.
