A passenger aboard the Regent Seven Seas Voyager cruise ship is stating on Cruise Critic that the ship is experiencing propulsion problems:

"We are trying to make our way to Shanghai and the ship has propulsion issues again. Our arrival is delayed 6 hours due to the propulsion issue and because we have missed high tide. We personally have lost 1 of our tours due to conflicting times, unfortunately it is one that was a big motivator for this trip. They have not mentioned to anyone on board that this is the 2nd time in the past couple of months the ship has had propulsion issues.

Not too impressed with the situation.

As well we are now missing 1 of our ports. Sounds vaguely similar to a couple of months ago on this ship."

There is also a comment on Twitter by a person who apparently communicated with a family member on the Voyager:

"Just talked to family onboard RSSC Voyager. 6 hrs late into Shanghai-propulsion problem. Skipping stop in Xiamen to get to HK."

If this information is accurate, then this is the sixth cruise ship which has experienced a engine / propulsion problem in the last two month.  Five of Carnival Corporation’s cruise ships have suffered engine / propulsion problems: the Carnival Triumph, Dream, Legend & Elation and the Carnival-owner P&O Ventura.
