Italian cruiseship builder Fincantieri has finalised a deal to build two more cruiseships for Torstein Hagen's Viking Cruises.
The vessels are the first in a series of six agreed subject to conditions last March.
The 47,800-gt ships will be delivered in 2024 and 2025.
They will house 930 passengers in 465 cabins.
Viking has placed orders for a potential 20 vessels with Fincantieri, which the Italian company says is a record for a single cruiseship owner at one shipyard.
