Norwegian Cruise Line Holdings to Sell Oceania Sirena
Sirena entered service in 1999 as R Four for Renaissance Cruises, part of an eight-ship R-class series built at Chantiers de l'Atlantique in Saint-Nazaire.
Updated August 7, 2026
Norwegian Cruise Line Holdings entered into a binding memorandum of agreement in July to sell Oceania Sirena, with a leaseback arrangement allowing Oceania Cruises to continue operating the 684-guest ship until its transfer in spring 2028. Sirena's farewell cruise is scheduled for March 24, 2028. The buyer has not been named.
The deal follows other R-class changes involving Regatta, Nautica and Insignia. Once those moves are completed, Insignia will be the only R-class ship left in Oceania's fleet.
Sirena sale follows changes for three sister ships
Oceania has agreed to charter the 1998-built Regatta to Australian tour operator myCruises for an initial two-year term. Regatta's farewell cruise for Oceania is listed for August 17, 2026. The charter may be extended for multiple years, or the ship may later be sold to another cruise operator.
Nautica, built in 2000, is being reimagined with lower capacity as Oceania Aurelia and will sail longer itineraries. Its farewell cruise in its current form is scheduled for October 15, 2027, ahead of a major refurbishment that will reduce capacity from 684 guests to fewer than 400.
Insignia, built in 1998, had previously been sold to Crescent Seas, a residential cruise startup, before that transaction fell through. Oceania currently lists Insignia departures through November 2027.
Former Renaissance ship has sailed under three brands
Sirena entered service in 1999 as R Four for Renaissance Cruises, which ordered an eight-ship R-class series built at Chantiers de l'Atlantique in Saint-Nazaire between 1998 and 2001. The ships were near-identical, at about 30,000 gross tons and roughly 180 meters long.
Renaissance Cruises collapsed in 2001. R Four then joined Princess Cruises and sailed there from 2002 through 2016 before becoming Sirena for Oceania. The ship underwent a significant refurbishment in 2019 as part of a $100 million fleet enhancement project, which transformed its staterooms, introduced a new suite style and revamped public spaces. Sirena currently has 337 suites and staterooms.
Oceania's eight-ship fleet spans the Regatta, Oceania and Allura classes. Regatta, Insignia, Nautica and Sirena make up the Regatta-class group.
NCLH discloses the sale in its second-quarter results
NCLH included the Sirena transaction in its second-quarter 2026 results, reporting total revenue of $2.6 billion, up 4.9 percent, and GAAP net income of $223 million. The company also identified another $100 million in expected annualized run-rate savings, primarily from capital expenditures and SG&A, after consolidating technology vendors and pursuing other salary-and-benefit savings.
Chief Financial Officer Mark Kempa said the Sirena agreement means NCLH expects five ships to leave its fleet over three years. Besides Sirena, the departures include Norwegian Sky and Oceania Regatta in 2026, followed by Norwegian Sun and Seven Seas Navigator in 2027.
Chairperson and Chief Executive Officer John W. Chidsey described the Sirena sale as "a deliberate portfolio action to move the Oceania fleet toward a product offering that better supports the brand's positioning and long-term return profile." He said the company is seeking to simplify Oceania's portfolio and align the fleet more closely with the brand's luxury positioning.
