Perilous Plunge, Water ride attraction at Knott's Berry Farm in Buena Park, California, United States.

Perilous Plunge was a water ride at Knott's Berry Farm in California featuring a tower structure that lifted boats before they descended into a splashdown pool. The boats made a sharp turn at the top before dropping at a steep angle toward the water below.

The attraction opened on September 15, 2000, and closed on September 3, 2012. The space was later used for three new rides that replaced it.

The nine-million-dollar Shoot the Chute ride established records as the tallest and steepest water-based attraction in the world when it opened in 2000.

Each boat held 24 passengers who wore safety harnesses during the ride. Visitors got soaked during the descent and needed to prepare for getting wet.

The ride's adjustable electromagnetic brakes did more than slow the boats: they let operators tune how much water the hull displaced on impact, controlling the size of the splash. High-performance pumps moved about 150 cubic metres of water per minute up the 37-metre lift hill.
