SEABOURN CRUISES released details of the design plan for the first of the two $250 million, 450-passenger ships it commissioned from Italy's T. Mariotti shipyard. Seabourn said the yard recently cut the first steel plates for the ship, which is slated to enter service in June 2009. The ship will have 13 categories of suites, four dining venues and six bars; it was designed to mirror the silhouette of the existing Seabourn ships but contain additional facilities and amenities. At three times the size of current Seabourn vessels but just double the passengers, Seabourn said the ship would have one of the highest space-per-guest ratios in the industry. "We've been careful to incorporate Seabourn's signature features while designing the next generation of ultra luxury ship to satisfy the desires of a new generation of luxury travelers," said Pamela Conover, Seabourn president and CEO, in a statement.
