The Grand class is a class of cruise ships. Ships in the class are operated by the cruise lines Princess Cruises or P&O Cruises. The class consists of several series (subclasses) of sister ships, most of which were built by Fincantieri in Monfalcone and Trieste, northern Italy. The first vessel of the original Grand class, the Grand Princess, entered service in 1998.
Ships of the later subclasses are based on the Grand class, but have modifications such as additional decks and varied placement of major amenities such as the nightclub and restaurants. The 'Skywalkers' nightclub is a signature element of Princess Cruises' ships in the Grand class and derived classes. The nightclub either overhangs the stern of the ship (Grand and Caribbean classes) or is located just aft of the funnel (Gem and Crown classes).
The Gem class of ships is based primarily on the Grand class, but modifies the placement of the Skywalkers nightclub to be just aft of the funnel and also modifies the number of restaurants. The two Gem class ships were built by Mitsubishi in Nagasaki, Japan in 2004.
