Royal Caribbean's Anthem of the Seas has encountered a significant technical issue, causing a delay in its return to Sydney on January 27, 2026. The ship's next cruise has been canceled to allow for comprehensive repairs. Royal Caribbean is offering compensation to affected guests, including change fees and travel plans adjustments. The issue is suspected to be related to the ship's propulsion system, which could impact its speed and ability to follow the planned itinerary. Guests have been informed of the situation and are being provided with reimbursement options for onward travel after debarkation. The ship's top speed is 22 knots, and it is currently traveling at 14 knots, significantly slower than its usual pace. Royal Caribbean is also offering compensation for flight changes and hotel accommodations, and guests will receive a 100% refund for the canceled cruise, along with a 25% future cruise credit. The technical issue is not related to navigational or safety systems, and all onboard operations are proceeding as planned. This is not the first time Anthem of the Seas has faced propulsion difficulties, and the ship is expected to undergo repairs during the canceled sailing period.
