Norwegian Cruise Line Holdings is venturing further into the luxury market.

The New York-listed company has placed an order for a 750-berth passengership for its luxury brand Regent Seven Seas Cruises from Fincantieri.

The €475m ($542m) investment is set for delivery in late 2023 and will sail as a sister ship to 754-berth Seven Seas Explorer (built 2016) and 750-berth Seven Seas Splendor, to be delivered in 2020.
