Norwegian Line Holdings (NCL) and Italian shipbuilder Fincantieri said on Wednesday they had agreed a deal for four new cruise liners, which a source close to the matter said was worth around 9 billion euros ($9.

Norwegian Cruise Line will follow up its Prima-Plus class with its largest ship class to date.
