Crystal Cruises' river cruise ship Crystal Mozart is slated to be handed over to a sister company under the Genting Hong Kong group in 2020.
The vessel will operate under a Genting Cruise Lines venture that will be announced at a later date.
Crystal Mozart's final Crystal voyage, which will be from Vienna to Budapest, is scheduled for December 2 of this year.
With Crystal Mozart's eventual departure, only the identical 135-metre-long sisters Crystal Bach (pictured), Crystal Debussy, Crystal Mahler, and Crystal Ravel will remain in the Crystal Cruises fleet.
