Katapul is a steel launched shuttle roller coaster located at Hopi Hari in Vinhedo, São Paulo, Brazil. The ride was one of the first Shuttle Loop models built by Schwarzkopf and used a weight drop launch to propel riders to a speed of 53 mph. It is also the most traveled, having operated at four parks in its 46 year history.


The ride was first installed at Kings Dominion in Virginia and opened on May 26, 1977 under the name King Kobra.[1] It was the first Schwarzkopf Shuttle loop model, along with White Lightnin' at Carowinds and Greased Lightnin' at Marriott's Great America, both of which opened in the same year. The ride closed in 1986 and was sent to Jolly Roger Amusement Park in Maryland, USA.

King Kobra reopened under the same name at Jolly Roger Amusement Park in Maryland in 1987 and only operated for three seasons, closing in 1989.

The ride was then sold to Alton Towers in England. It opened in 1990 and was called Thunderlooper. Thunderlooper was situated across from where Nemesis is now in a newly created area called Thunder Valley (now Forbidden Valley). During its operation, planning regulations on Alton Towers were tightened, allowing nothing to be built higher than the treeline. Due to its height and noisy operation, Thunderlooper had to be closed - it ceased operation on November 3, 1996. Maintenance had also become an issue with cracks appearing on the track and trains. It was replaced with flat rides Ripsaw and Blade.[2]

After being removed from Alton Towers, the ride was sent to Hopi Hari in Brazil. The attraction was repainted blue with red supports and opened in 1999 under the name Katapul. It was closed in February 2012 and was repainted red with blue supports. The ride was also given a new Superman theme. Katapul reopened on December 14, 2012. The superman theme was removed for the 2021 season.



Ride experience

The train is launched out of the station at a speed of 53 mph before passing through a vertical loop with a diameter of 46 feet. It then travels up a 148 feet tall vertical rollback, slowing to a halt as it loses its momentum. The train then traverses the track backwards, passing through the vertical loop and station and up the second, smaller spike. After stalling a second time, the train rolls forwards into the station.

Colour scheme

Katapul has red track and blue supports. The ride originally opened with white track and supports in Kings Dominion, being repainted to Black track and supports at Jolly Roger Amusement Park. Alton Towers saw the ride being repainted to feature dark green track and supports. It was eventually repainted to feature blue track and red supports when relocated to Hopi Hari, before receiving its current scheme.


Single train with 7 cars. In each car, riders are arranged 2 across in 2 rows, for a total of 28 riders per train.
