Ride


Layout and design

The Giant Inverted Boomerang is a departure from Vekoma's earlier Boomerang designs. This model features a vertical cable lift hill that quickly lifts the train up a vertical tower. Also, this model is larger than previous Boomerang designs. From above, the track layout looks like an 'X'.


Train

As a Giant Inverted Boomerang is a shuttle roller coaster, each installation only operates with a single train of eight cars, each utilizing four-across seating, similar to that on

(different from the originals built by Vekoma). This train had four-across seating, similar to Bolliger & Mabillard's inverted roller coasters. The new train design was chosen in an attempt to make the lines in the station less complicated to navigate and also to give the ride a higher capacity.


Experience

The ride begins when the train slowly backs out of the station and up the vertical lift, pulled by a catch car. Once reaching the top of the lift, with riders facing straight down, and their legs dangling in the air, the train is released and zooms through the station heading into a tall

. This element contains two of the three inversions found on the ride going forward. After twisting through the Boomerang, riders then go through a tall vertical loop which crosses over the station and hit the second vertical tower of the ride. A catch car there pulls the train up the second vertical tower, this time with riders facing the sky. After the train reaches the top of the tower, it is released to cycle backward through the layout. The train then goes through the station and heads up the first vertical lift again, where it is caught once more by the catch car and then very slowly lowered back into the station.

'': “Fixed-site amusement park rides like those at Six Flags New England are exempt from federal oversight due to a 30-year-old special-interest loophole.

Also, the jerky motions of these rides have been linked to small tears in
