Princess Cruises has signed a contract with Fincantieri for two 4,300-guest ships.

The ships – to be delivered in 2023 and spring 2025, respectively – will be the first Princess vessels to be dual-fuel powered, primarily by liquefied natural gas (LNG) – a more environmentally friendly fuel.

Princess Cruises president Jan Swartz said: “[The brand] continues to grow globally, adding new ships to our fleet built by our long-time trusted ship building partner, Fincantieri, who brings decades of expertise to these next-generation cruise ships.

“Even more exciting is that these two ships are being designed to include our MedallionClass platform, powered by Ocean Medallion, the most advanced wearable device available within the global hospitality industry.”

Fincantieri CEO Giuseppe Bono said: “This result proves, once again, the trust we receive from the market, which allows us to look to the future with ambition. It honours our great work focused on innovation thanks to which we have been able to offer to the client a record-breaking proposal not only in terms of size.

“We firmly believe that a new class of Princess Cruises’ ships can stem from this promising project. In fact, for Princess Cruises, we have received orders for 21 ships, another unprecedented result in this industry.”
