What was the first ship that AquaDuck was constructed
AquaDuck AquaDuck is a water coaster (a water slide with similar turns, drops and g-forces to a roller coaster) that is located on the deck of two Disney cruise ships. It was first constructed on the "Disney Dream" in January 2011 and then later on the "Disney Fantasy" in February 2012. It was developed by Walt Disney Imagineers, and despite a few exceptions, is accessible to almost anyone. The AquaDuck is the first water coaster to exist on a cruise ship, and so far it is the only one of its kind.
HMS X1 HM Submarine "X1" was conceived and designed as a submersible commerce raider for the Royal Navy; at the time of her launching she was the largest submarine in the world. The idea of a submarine cruiser had been proposed as early as 1915, but was not put into practice until 1921. "X1", which was based on the uncompleted German "U-173" class of 2,000-ton "U-cruisers", was laid down on 2 November 1921 at the Naval Dockyard Chatham and completed on 23 September 1925, commissioning in December 1925.
