Norwegian Cruise Line Holdings announced on Thursday that it had sold the 1999-built Oceania Sirena, with the ship set to change hands after its spring 2028 season. As with most secondhand tonnage deals, the buyer is likely to be a non-competitor to NCLH’s trio of brands. As NCLH repositions its Oceania brand upmarket, four of those R-class ships now appear headed for new homes. Alongside the Ambition, Ambience and Renaissance (CFC brand), the Sirena would be a smaller but a notably more premium product.
