Six sweeps (arms) are attached to a center tower. At the base of each sweep is a car carrying four people, in pairs sitting side-by-side. Riders are restrained by a locking lap bar, with no dividers in between the side-by-side riders (unlike the new model Downdraft with over shoulder harness and increasing passenger per car to five). Old versions of the ride did not compensate for lateral movement considering the sweeps were attached directly to the top of the cars (Saturn 6). The Hurricane and Downdraft use a car mount pivoting saddle in which the cars are placed held upright by angular retention cables mounted to the top of the rotating part of the tower just above the sweep bushings to compensate for lateral movement. Most operators of the Hurricane and Downdraft require riders to be tall or more, with smaller riders usually required to be seated on the inner seat of the cars due to the strong centrifugal force of the device.
