The Space Boat is an almost unique ride in the archives of Alton Towers, as it was open for so little time it didn't make it onto the park map or promotional material. The ride operated for less than a single season in 1983 in the Ingestre Centre, roughly where the waterfall entrance to Katanga Canyon is now.
It is widely believed that the ride was the first victim of the restrictive height limits placed on the park, however, the ride does seem to have received planning permission. Whatever caused the ride to be removed after such a short period of time, the Space Boat was replaced by the Octopus in the 1984 season.
But the story didn't end there... After its tenure at Alton Towers, the ride breifly ended up at the short-lived Atlas Park with Brian Collins, the showman who had previously run the Amusement Park at Alton Towers in the 60s and 70s.
