Princess Cruises' 710-passenger Royal Princess, one of its smallest ships, will transfer to the line's UK-based sister company, P&O Cruises, in spring 2011.
The ship will be renamed Adonia during a drydock prior to the transfer.
The 30,200-ton, 710-passenger Royal Princess has sailed with Princess for less than three years. The former R-ship transferred to Princess in spring 2007 after its former owner, Swan Hellenic, was shut down by Carnival Corp.
The move will mean another reduction in Princess' Alaska capacity during the 2011 season.
In summer 2010, Princess will sail seven ships in Alaska versus eight in 2009, a 16% capacity decrease, by taking the Star Princess out of the Alaska market. The Royal Princess will sail 14-day roundtrip cruises from Seattle to Alaska in summer 2010.
Princess said that as a result of the Royal Princess transfer to P&O, five sailings in April and May 2011 -- two in Tahiti and French Polynesia, one between Tahiti and Hawaii and one in Hawaii -- as well as a one-day coastal trip, will be cancelled and replaced by a 26-day cruise from Papeete, Tahiti, to Fort Lauderdale that will call as far south as Lima, Peru, and will transit the Panama Canal.
This article has been updated to reflect that the Royal Princess is one of Princess' three smallest ships, also including the Ocean Princess and the Pacific Princess.
