Boomerang: Coast to Coaster is a steel roller coaster of shuttle design currently in use at four different Six Flags & EPR theme parks. The ride was designed and manufactured by Vekoma, and is considered as one of its boomerang models. Each coaster has one train with a capacity of 28, two across in each row. Unlike Vekoma's suspended trains, "Boomerang: Coast to Coaster" operates a sit-down design. When the coaster starts, the train is pulled backwards up the lift hill, then dropped through the loading gate through a cobra roll and then one loop. At the end of this cycle the train is pulled up the lift hill at the end of the track, then dropped once again allowing the train to go back through the loops backwards, hence the name "Boomerang: Coast to Coaster."
