Around 145 Australians and New Zealanders have had their cruise cut short this week after Azamara Journey experienced ‘unusual vibrations’ at sea.

The 684-passenger vessel was on the eighth night of a 14-night East China & Japan itinerary from Hong Kong to Shanghai when crew felt the ship shake.

An inspection revealed one of the ship’s two propellers had experienced damage from debris.

“We are now traveling at a reduced speed to Osaka (Kyoto), and will arrive on Friday,” an online update said.

Once the ship reaches Kyoto it will be repaired. However, the line said an upcoming voyage out of Shanghai on 3 March may also be affected.

“We will provide an update within 48 hours, and all guests – or their travel agents – on those voyages will be contacted directly with more information.”

Passengers on the current cruise will remain on the ship in Kyoto. They will disembark on 2 March.

Azamara Cruises said it will provide air transport to Shanghai where the cruise was originally scheduled to end on 3 March.

Accommodation will be provided to cruisers until they are able to pick up their original schedule.

Additionally, passengers will receive refunds for the days of the voyages they will be missing and a Future Cruise Credit certificate of 25 percent the value of their current voyage.
