Boomerang: Coast to Coaster

Boomerang: Coast to Coaster is a steel shuttle roller coaster currently at several parks in North America. The roller coaster was designed and manufactured by Vekoma, and is considered as one of its boomerang models. At the time of installation in the late 1990's, the coaster was built at parks operated by Six Flags. All five coasters was once name, Boomerang: Coast to Coaster and three have been renamed.

Design and operation
Originally, the coasters had a teal track & white supports. As of 2015, Six Flags Darien Lake's model still has its original colors; Six Flags Discovery Kingdom's model has teal track and yellow supports; Elitch Gardens' model has a yellow track and purple supports; and Six Flags Fiesta Texas' has teal track and orange supports.

This is the standard Vekoma Boomerang roller coaster design found at forty-three different amusement parks worldwide.

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."
