The Space Boat is an almost unique ride in the archives of Alton Towers as it never actually appeared in any park map or promotional material since it operated for less than a single season. The ride was installed during the 1983 season 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... The ride still operates in the UK today, nearly 40 years after it first opened at Alton Towers. Since its tenure at Alton Towers the ride has had a number of homes, including Dreamland Margate and Loudon Castle. After the closure of Loudon Castle the ride found a new home at Lightwater Valley where you can still experience it as The Black Pearl.
