The AquaDuck is a "water coaster" located exclusively on the Disney Dream and the Disney Fantasy. It was the first water coaster at sea and remains one of the most popular features of Disney Cruise Line's mid-sized ships. The ride consists of a transparent acrylic tube that winds over the side of the ship and through the forward funnel, offering a thrilling view of the ocean 150 feet below. It uses high-powered water jets to propel a two-person raft uphill and through a series of turns and drops. It is a 765-foot long course that takes about a minute to complete. Note that the newer "Triton Class" ships (the Disney Wish and Disney Treasure) feature a different attraction called the AquaMouse, which is described as Disney's first "attraction at sea" because it includes animated screens and a storyline. If you specifically want the classic AquaDuck experience, you must book a sailing on either the Dream or the Fantasy.
