Mammoth (ride)

Mammoth uses a total of ten yellow, 6-passenger boats called "round spinners". In each of the round spinners, riders are seated in a circle facing each other. Each seat has individual seat backs and two handles to hold on with, one on the rider's left and one on the rider's right. To allow the linear induction motors to interact with the boats and propel them uphill, a magnetic metal plate is attached to the underside of every boat.[2]

The track on Mammoth is made out of numerous pieces of molded, red, yellow, and blue fiberglass supported by concrete pillars. The total length of the track is 1,763 feet (537 m) and includes seven drops, with the largest being 32 feet (9.8 m). The track features a conveyor belt lift hill as well as six linear induction motors that propel the boats back uphill, including the longest LIM on a water coaster.[2]

The technology on HydroMagnetic Rockets utilizes linear induction motors (LIMs) to propel boats uphill. An alternating magnetic field beneath the slide surface interacts with a steel plate mounted on the underside of each boat to push them uphill smoothly and quickly. Because the magnetic field under the slide surface needs power in order to be activated, boats will not be able to make it uphill in the case of a power outage. In that case, all of the boats throughout the course will roll back, causing each boat to valley at the bottom of a hill. LIM technology is commonly used on launched roller coasters.[3]

The ride begins with riders facing away from Bakuli. After dispatch, the boat travels up a slight incline where it waits until there is adequate spacing between it and the boat in front of it. When the ride's system has determined there is adequate spacing between the boats, the boat moves forward and onto the conveyor belt lift hill. While on the lift hill, riders will pass under one of the ride's drops and over two of its inclines. At the top of the lift hill, the boat moves from the conveyor belt onto the fiberglass. At this point the boat makes a right turn before entering the ride's initial 32 feet (9.8 m) drop at a 45° angle. Following the descent, the boat is rocketed back uphill by the first of six linear induction motors. The boat crests the hill and makes a left turn, in preparation for a dropping, right-hand, hairpin turn. At the bottom of the dropping hairpin turn, the boat is sent uphill for a second time before making another descent.[4]

At the bottom of the third drop the boat passes under the lift hill and is launched uphill a third time. The boat turns left before it drops down under the lift hill. At this point the boat glides uphill and into a left-hand, 270° turn. The boat then travels downhill before going back uphill, this time over the lift hill. After going down hill and uphill one more time, the boat enters a right-turning helix. Once the boat has navigated the helix, it makes a left turn before dropping a final time. At the conclusion of the drop it lands in a splash pool of water, floating in a current with mild rapids for several yards before making a left turn to line up with the end-of-the-ride conveyor belt. The final conveyor belt brings the boat into the station, at which time riders unload.[4]
