Sun Princess® leads the next generation of ships. Sun Princess® is the first ship in the fleet to be powered by Liquified Natural Gas (LNG). This cleaner burning fuel will significantly reduce air emissions and marine gasoil to minimize the environmental footprint. She is the third ship to be honored with the Sun Princess® name, adding to the legacy of the first ship sailing from 1974 to 1988 and the second ship sailing from 1995 to 2020. At that time, she had the largest number of balcony cabins and the first 24-hour cafe.
