A cry of "Man overboard" will have a new, less dire connotation aboard the Disney Dream.

AquaDuck -- the first water coaster aboard a cruise ship -- will send passengers sailing 13 feet over the edge, 150 feet above the water's surface, rafting a clear, acrylic tube before returning above the top deck of the Disney Cruise Line ship.

"This isn't a passive experience -- from top to bottom," said Greg Dauberger, director of design and production for Walt Disney Imagineering.

The ride was among the Dream details revealed Thursday afternoon in New York. Scheduled to debut in January 2011, the ship will sail from Port Canaveral with three-, four- and five-night cruises to Nassau, Bahamas, and Castaway Cay, Disney's private island.
