Capt. Srecko Ban sent a letter to passengers, in which he stated:
"Anthem of the Seas experienced a technical issue on one of its propulsion motors."
He indicated that ship's engineering team was working on the issue, but in the meantime, Anthem of the Seas would be sailing at reduced speed.
Capt. Ban made it clear that all remaining motors were fully operational, and there was no impact on the maneuverability of the vessel or the safety of passengers and crew.
