Seabourn Cruises' third Odyssey-class ship will be called the Seabourn Quest, when the ship launches in 2011.
The first of the three ships, the 450-passenger Seabourn Odyssey, debuted last summer. The second, the Seabourn Sojourn, will launch this June in London.
The Quest will be Seabourn's sixth vessel, with the three Odyssey-class ships representing a 200% capacity increase for Seabourn over a three-year period.
Seabourn CEO Pamela Conover said in a statement that the names of the three ships "represent the passion for adventure and discovery that spurs our guests’ desire to travel in Seabourn style."
