A Water Coaster--at Sea?

Other cruise lines have included water park slides aboard their ships. But when the Disney Dream launches in 2011, it will feature AquaDuck, the industry's first floating water coaster. The ride's 756-foot long see-through tube will extend beyond the side of the ship, sending passengers zooming high above the ocean. AquaDuck will use jets of water to propel riders' rafts up and along the route as it circles the ship.

Disney Imagineers will incorporate other goodies into the Dream, including "virtual portholes" for inside cabins. High-definition screens will mimic windows by relaying real-time footage shot outside the ship. Taking whimsy to the high seas, animated characters such as Mickey Mouse and some of Nemo's pals will occasionally float past the virtual windows. Disney has posted a computer-generated video of the AquaDuck water coaster.
