From a chartered ship to a $5.4 billion global cruise empire

In short: Princess Cruises didn't start with a fleet of luxury liners. It began in 1965 with a single chartered ship that lacked air-conditioning, making it nearly unfit for the tropical routes it was meant to sail. Today, it is a cornerstone of the world's largest cruise operator.

The origins of Princess Cruises are rooted in pragmatic chartering rather than immediate ownership. In 1965, founder Stanley McDonald chartered the Princess Patricia, a Canadian Pacific Limited ship. Because the vessel was never designed for tropical climates and lacked air-conditioning, the charter was short-lived. The company quickly pivoted to a more suitable ship, the Italia, which inaugurated their Mexican Riviera cruises from Los Angeles.

The brand's growth was significantly accelerated by media and strategic acquisitions. In the 1980s, the company rose to prominence after the television series The Love Boat featured the Pacific Princess. This cultural footprint was bolstered by the 1974 acquisition of the line by Britain's P&O, which brought in the first Sun Princess. A pivotal moment occurred in 1988 when P&O Princess Cruises acquired Sitmar Line, a move that added major tonnage and several new builds, transforming Princess into a primary competitor in the Caribbean.

The modern era of the brand was defined by massive scale and corporate integration. In 2003, a $5.4 billion merger with Carnival Corporation created the world's largest cruise operating company. This led to the development of the Royal-class ships, which, at over 140,000 GT, became the largest vessels ever constructed for the line. While the brand began with a single ship struggling with heat, it now operates a sophisticated fleet of 17 ships across global itineraries.

The company's evolution also involved a complex web of ship swapping and rebranding. For instance, the Royal Princess—the line's first purpose-built ship—served for 21 years before being transferred to P&O in 2005. These maneuvers, combined with the development of private island resorts like Princess Cays in 1992, illustrate a shift from simple maritime transport to a vertically integrated luxury travel experience.
