Seabourn Cruise Line is a luxury small shipcruise line headquartered inSeattle, Washington.^[1] It is owned byCarnival Corporation & plc.

Seabourn Cruise Line was founded in 1986 under the name "Signet Cruise Lines" by the Norwegian private investorAtle Brynestad and Warren S. Titus.^[2] The name "Seabourn Cruise Line" was adopted shortly afterward following objections over trademark ownership by Signet Oil.^[3]

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 byRoyal Viking Line in 1992 asRoyal Viking Queen. In 1995,Royal Viking Queen was transferred to a Kloster subsidiary,Royal Cruise Line, asQueen 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 theQueen Odyssey, which was then renamedSeabourn 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, andRoyal Viking Sun were transferred into the Seabourn fleet asSeabourn Goddess I,Seabourn Goddess II, andSeabourn Sun.^[4]

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 andSeabourn Goddess II were sold to Seabourn's original founder, Atle Brynestad, in order to establish his own cruise lineSeaDream Yacht Club. In 2002,Seabourn Sun was transferred to the Carnival-ownedHolland 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 fromGenoa's T. Mariotti shipyard. The first, namedSeabourn Odyssey entered service in 2009, followed by theSeabourn Sojourn in 2010 and theSeabourn Quest in June 2011. The three ships share most features. TheOdyssey,Sojourn, andQuest have a maximum passenger capacity of 450 guests, quartered in 225 suite cabins, 90% of which have a balcony. The 650-foot (200 m) vessels cost approximately US$250 million each. The ships have 11 decks, an 11,500-square-foot (1,070 m²) indoor/outdoor spa, and four alternative dining venues.^[5][6]

On March 31, 2011, Seabourn moved operations from Miami, Florida, to the Holland America Line quarters in Seattle, Washington.^[7]

It was announced on February 19, 2013, that Seabourn reached an agreement withWindstar Cruises for the sale of the three smaller Seabourn ships.Seabourn Pride departed the fleet in April 2014, sistersSeabourn Legend &Seabourn Spirit departed in April and May 2015, respectively. No cruises were cancelled as the ships sailed with Seabourn until their initial dry dock periods.^[8]

On October 18, 2013, Seabourn announced it had signed a Letter of Intent for the construction of a new cruise ship with Italian shipbuilder Fincantieri. The new ship was modeled after the line's three newest vessels,Seabourn Odyssey,Seabourn Sojourn andSeabourn Quest. Delivery was completed in 2016.^[9] The vessel replaced the capacity that left the Seabourn brand with the sale ofSeabourn Pride,Seabourn Spirit andSeabourn Legend. In July 2018, the cruise line announced it would add two expedition ships to its fleet.Seabourn Venture was delivered on June 29, 2022 and inaugural voyage on July 27, 2022.^[10]Seabourn Pursuit is scheduled for delivery in February 2023.

On March 16, 2023 Seabourn announced thatSeabourn Odyssey would be sold toMitsui O.S.K. Lines, Ltd. (MOL). The ship will remain with the brand under a charter agreement through the end of August 2024.^[11]

On March 4, 2025 Seabourn announced thatSeabourn Sojourn would also be sold toMitsui O.S.K. Lines, Ltd.. The ship will remain with Seabourn through all its current sailings through May 2026.^[12] With those sales, the capacity will shrink by 15 percent between 2021 and 2026 despite the newbuilts.^[13]
