The design of the boats appears very similar to those illustrated in a "Boat Ride Apparatus" patent filed by Edgar A. Morgan and Karl W. Bacon, of Arrow Development. Arrow Development was involved in the design of many attractions at Disneyland between 1953 and 1973.
Major changes took place in 1959 to the three attractions in the area. The Viewliner and its railroad track were gone. Instead, the elevated beam of the new Disneyland Alweg Monorail curved overhead. The new Fantasyland Autopia and an expanded Tomorrowland Autopia replaced the Junior Autopia. The lagoon which had once been home to the Phantom Boats was used for the Submarine Voyage but the Motor Boat Cruise remained.
