DESCRIPTION:  Mammoth, the World’s Longest Water Coaster, uses HydroMagnetic technology to propel six- and eight-person boats up a series of hills utilizing linear induction motors (LIMs). The water coaster begins with a 300-foot conveyor ride “lifthill,” followed by a series of drops including a three-story drop at a 45-degree angle. The drenching ride includes a total of seven drops, adding up to 187 feet of total “drop.” Mammoth’s length is the greatest of any water coaster in the world: 1,763 feet, a third of a mile.

FEATURES:  Located in Splashin’ Safari, Mammoth begins with a conveyor ride up the water coaster’s lifthill. Including a 32-foot drop at a 45-degree angle plus six additional drops, linear induction motors (LIMs) propel the six-person round boats up six hills, through five enclosed sections, and around twists and turns.

TECHNOLOGY: HydroMagnetic technology utilizes LIMs to propel Mammoth’s boats up the water coaster’s hills. An alternating magnetic field beneath the slide surface propels the boats, pushing them rapidly and smoothly uphill. LIM technology is a popular feature in some steel roller coasters.

WORLD RECORD LENGTH: Mammoth’s length is 1,763 feet (1/3 of a mile), making it the World’s Longest Water Coaster. (The park’s Wildebeest water coaster falls to the #2 position.)

RIDE LENGTH:       1,763 feet, the World’s Longest Water Coaster.

DROPS/ANGLES:    The tallest drop is 32 feet at a 45-degree angle. Together with six additional drops, combined length of the “drops” is 187 feet.

RIDE HEIGHT:  Mammoth is 69 feet tall, from the lowest to the highest heights.

RIDE TIME:      Approximately three minutes.


FOOTPRINT:   Mammoth covers approximately 3.2 acres in Splashin’ Safari.

BOATS:          10 six-passenger Round Spinners boats and four eight-passenger Forward Fliers, all with individual seatbacks.

STAIRS:          None! Riders begin at ground level and ride up a conveyor.

CAPACITY/HEIGHT LIMIT:  1,050 pounds per six-person Round Spinners boat and 1,400 pounds per eight-person Forward Fliers boat.

INVESTMENT:        $9 million, the largest ride project in Holiday World’s 66-year history.

RIDE DESIGNER:    ProSlide Technology Inc., Ontario, Canada.
