UK owner Saga Cruises has reportedly declared an option for a second cruiseship at Meyer Werft in Germany.
The vessel will be delivered in summer 2021, according to BRL Shipping Consultants.
The 57,000-gt ship was part of a contract signed last year.
Saga will take delivery of the first 1,000-passenger vessel in 2019.
The over-50s specialist currently operates two 1981-built cruiseships.
It and the shipyard have been contacted for comment.
