Princess Cruises' new ship Star Princess completes sea trials

Princess Cruises' second Sphere-class ship, the Star Princess, has successfully completed its sea trials in the Adriatic Sea and is on track for its scheduled maiden voyage on October 4, 2025. The vessel, which is currently under final construction at the Fincantieri shipyard in Monfalcone, Italy, conducted a comprehensive series of tests from August 9 to 12.

The sea trials validated the ship's steering, navigation systems, and propulsion. As the second ship in the Princess fleet to be powered by liquefied natural gas (LNG), the Star Princess features two azimuth propulsion units and four large controllable pitch bow thrusters to optimise power efficiency and maneuverability.

Princess Cruises said a team of 1,600 crew members is preparing the vessel for its entry into service.

The 177,800-tonne, 4,300-guest Star Princess is a sister ship to the Sun Princess. Onboard venues include a multi-level entertainment and relaxation space; a theatre; and “The Piazza”, which the company described as the ship's architectural centerpiece. The ship also features over 1,500 balcony staterooms and 30 dining and bar venues.
