Crown Cruise Line's new vessel, the Crown del Mar, is scheduled to begin sailing two- and five-day cruises from the Port of Palm Beach late this fall - two days to Nassau and five days to Key West, Cancun and Cozumel.

The 10,000-ton, 500-pax ship is undergoing a complete rebuilding at the Union Navale de Levante shipyard.

A marketing campaign is due to break shortly with brochures, publicity, advertising and travel agents' seminars.
