Princess Cruises has taken another step towards launching two new 175,000 tonne cruise ships by signing the final contracts with shipbuilders Fincantieri.

The announcement by Fincantieri follows the initial signing of a memorandum of agreement between the two parties in July last year.

Each vessel will carry around 4,300 passengers and be powered primarily by Liquefied Natural Gas (LNG) to cut air emissions.

The vessels are due for delivery in late 2023 and in spring 2025.

Princess Cruises’ president Jan Swartz said: “Princess Cruises continues to grow globally – adding new ships to the fleet built by Fincantieri.”

Medallion technology will be available on both ships.

Caribbean Princess and Regal Princess both have the technology currently.

The wearable technology which serves as a room key, onboard charge card and a virtual concierge, will be available on Royal Princess from April, Crown Princess from July and Sky Princess from October when it joins the fleet.

Princess Cruises has five new ships being built over the next six years.
