Seabourn Cruise Line is a cruise line headquartered in Seattle, Washington. It is owned by Carnival Corporation & plc. History Seabourn Cruise Line was founded in 1986 under the name "Signet Cruise Lines" by the Norwegian private investor and Warren S. Titus. The name "Seabourn Cruise Line" was adopted shortly afterward following objections over trademark ownership by Signet Oil. Its first ship, Seabourn Pride, entered service in 1988, followed by an identical sister, Seabourn Spirit, in 1989. A third vessel, originally planned for 1990, was delayed due to investors' financial constraints and was ultimately purchased by Royal Viking Line in 1992 as Royal Viking Queen. In 1995, Royal Viking Queen was transferred to a Kloster subsidiary, Royal Cruise Line, as Queen Odyssey. In 1991, Carnival Corporation purchased a 25% stake in Seabourn. Carnival Corporation increased its stake to 50% in 1996, providing the company sufficient capital to purchase the Queen Odyssey, which was then renamed Seabourn Legend. In 1998, in partnership with a consortium of a Norwegian businessmen, Carnival purchased the remaining 50% stake in Seabourn, as well as acquiring the Cunard Line from Kvaerner ASA, and merged the two brands into an entity called Cunard Line. In 1999, three Cunard ships, Sea Goddess I, Sea Goddess II, and Royal Viking Sun were transferred into the Seabourn fleet as Seabourn Goddess I, Seabourn Goddess II, and Seabourn Sun. In 2001, Carnival bought out the Norwegian shareholders, and Seabourn's parent company became a wholly owned subsidiary of Carnival. That summer, Seabourn Goddess I and Seabourn Goddess II were sold to Seabourn's original founder, Atle Brynestad, in order to establish his own cruise line SeaDream Yacht Club. In 2002, Seabourn Sun was transferred to the Carnival-owned Holland America Line, reducing the Seabourn fleet to its three original sister ships, and the company was demerged from Cunard Line and reorganized as a stand-alone operating brand of Carnival Corporation & plc. In October 2006, Seabourn ordered three new, 32,000-ton cruise ships from Genoa's T. Mariotti shipyard. The first, named Seabourn Odyssey entered service in 2009, followed by the Seabourn Sojourn in 2010 and the Seabourn Quest in June 2011. The three ships share most features. The Odyssey, Sojourn, and Quest have a maximum passenger capacity of 450 guests, quartered in 225 suite cabins, 90% of which have a balcony. The vessels cost approximately US$250 million each. The ships have 11 decks, an indoor/outdoor spa,
