Seabourn has announced the sale of the line's original three vessels Seabourn Pride, Seabourn Spirit and Seabourn Legend.
There will be no disruption in service or changes in operations on any currently published Seabourn voyages.
"Seabourn remains dedicated to our mission of creating the world's finest travel experiences through our small-ship cruising product," said Seabourn president Richard Meadows.
"Our three newest vessels, Seabourn Odyssey, Seabourn Sojourn, and Seabourn Quest have raised the bar for ultra-luxury cruising and we intend to add a fourth ship of similar design," he continued.
"Seabourn is already in discussion with shipbuilders and an order is likely to be announced within the current fiscal year. The new ship will allow Seabourn to maintain much of its current guest capacity."
