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.
Norwegian Cruise Line Holdings has agreed to sell Oceania Sirena, with Oceania Cruises expected to continue operating the 684-guest ship through its spring 2028 deployment under a charter arrangement. The buyer has not been named.
The deal follows other R-class changes involving Regatta, Nautica and Insignia. Once those moves are completed, Insignia is set to be the only remaining R-class ship in Oceania's fleet.
Sirena sale follows changes for three sister ships
Oceania has already chartered the 1998-built Regatta to myCruises for the next two years. Nautica, built in 2000, is being reimagined with lower capacity as Oceania Aurelia and will sail longer itineraries.
Insignia, also built in 1998, had previously been sold to Crescent Seas, a residential cruise startup, before that transaction fell through.
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.
After Renaissance Cruises collapsed in 2001, R Four joined Princess Cruises and sailed there from 2002 through 2016 before becoming Sirena for Oceania. Oceania's current eight-ship fleet spans the Regatta, Oceania and Allura classes, with Regatta, Insignia, Nautica and Sirena making 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.
NCLH did not provide a Sirena-specific executive comment in the earnings release. John W. Chidsey, chairperson and chief executive officer, said more broadly that the company is "still in the early stages of our turnaround" as it works on brand positioning, revenue management and cost efficiencies.
