The line behind the ‘The Most Luxurious Ship Ever Built’ has announced an order to build a third explorer-class ship.

The new vessel will be a sister ship to the Seven Seas Explorer and Seven Seas Splendor, is scheduled to be delivered in late 2023.

Voyages for the ship’s inaugural season will go on sale in 2021 and more details about the ship will be revealed leading up to her debut.

“When Seven Seas Splendor’s inaugural season went on sale in April 2018 we set a new single-day booking record for our 26-year-old company, demonstrating the anticipation for her 2020 arrival,” said Jason Montague, president and chief executive officer of Regent Seven Seas Cruises.

“Each new ship is progressively more successful. 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.”

She will be built to accommodate up to 750 guests and will be Regent Seven Seas Cruises’ sixth all-suite vessel.

“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. which owns Regent Seven Seas Cruises.

The new ship costs approximately €475 million (AUD$ 750.5 million) and will be built by Fincantieri.

The Italian builder is also currently building Seven Seas Splendor at its Ancona, Italy shipyard.

“This agreement is the perfect seal of the work our Group has carried out over the years and the role we have gained in the market … Quality is the shipowner’s hallmark and it entrusted Fincantieri once again,” stated Giuseppe Bono, CEO of Fincantieri.
