As of 2026, the smallest ships in the active Princess Cruises fleet are the sister ships Coral Princess and Island Princess. These "Coral-class" vessels have a gross tonnage of approximately 91,627 tons and a guest capacity of roughly 2,000 to 2,200 passengers. They were specifically designed with a narrower beam to allow them to transit the original locks of the Panama Canal, making them a favorite for enthusiasts of that specific itinerary. In contrast to the massive new "Sphere-class" ships like the Sun Princess (which carries over 4,300 guests), the Coral and Island Princess offer a much more intimate, classic cruising experience with fewer crowds and a higher crew-to-guest ratio. While the "R-class" Pacific Princess (which carried only 670 guests) was previously the smallest, it was sold in 2021, leaving the Coral-class as the "boutique" option for travelers who prefer a smaller ship feel without sacrificing the traditional amenities, diverse dining options, and large-scale entertainment typically found on a Princess cruise.
