The Navigator hasn't had the pod issues that Voyager and Mariner have had - it did have a minor vibration - it's a different build. I also think that Regent can't afford to do that to two ships on top of hte Mariner issues of this year - and now Voyager being delayed. Probably wise to delay Voyager - it's due for the World Cruise next month - Regent's best repeat customers will be on board
