Princess Cruises has signed final contracts for two new vessels at Fincantieri in Italy.
A preliminary deal for the 175,000-gt pair was agreed last July.
They will be the largest such ships ever built in Italy.
The Monfalcone yard will deliver them in late 2023 and in spring 2025.
The units will house 4,300 guests and will be the first Princess vessels to be dual-fuel, powered primarily by LNG.
