Regent Seven Seas Cruises is to build a third Explorer-class vessel due for delivery in 2023.

The €475m vessel will be sister ship to Seven Seas Explorer and Seven Seas Splendor.

The ship will be built in Italy’s Fincantieri shipyard and accommodate 750 guests.

It will be Regent’s sixth-all-suite vessel.

Details about itineraries, suites, restaurants, amenities and onboard experiences will be revealed leading up to her 2023 debut and will go on sale in 2021.

President and chief executive Jason Montague said: “Our growth is a reflection of the amazing people who work across our fleet, our valued shoreside employees, our loyal guests and their trusted travel advisors.”

Over the past 12 months Regent has completed a $125 million remodelling of its fleet and started construction on Seven Seas Splendor at Fincantieri’s Ancona shipyard.

Regent is owned by Norwegian Cruise Line Holdings Ltd.

Harry Sommer, NCLH’s international president, said: “If you think about the growth of the brand – the Navigator, the Explorer and the Voyager – we have more than doubled the fleet in a short amount of time. It is an upscale product, too.”

He added that there would be “little tweaks” between the third Explorer-class vessel and its sister ships.

“We are excited to build on the spectacular success of Seven Seas Explorer and Seven Seas Splendor as we embark on bringing to life a new vessel that will set an even higher benchmark for elegance, luxury and style,” said Frank Del Rio, president and chief executive officer of Norwegian Cruise Line Holdings Ltd.

“This new ship further strengthens our company’s robust yet measured growth profile with vessels now on order for all three of our award-winning brands, enabling us to expand our presence globally, further diversify our product offerings and continue to drive shareholder returns.”
