Perilous Plunge

Perilous Plunge was a shoot-the-Chutes style attraction located at Knott's Berry Farm in Buena Park, California. The ride opened on September 15, 2000, and closed on September 3, 2012.
Overview.
The attraction was based on the pleasure piers of the past along Southern California's famed beaches such as Huntington Beach. 24-passenger boats were towed to a height of where a brief U-turn was taken before a world record water chute into a 650,000-gallon "splashdown" lagoon.
On 13 August 2012, Knott's Berry Farm announced that Perilous Plunge would be closing for good on September 3, 2012, in order to make way for a new attraction. The ride has been replaced by three new rides: Coast Rider, Surfside Gliders and Pacific Scrambler, which all opened in 2013.
Records.
Perilous Plunge made its debut as the tallest and steepest water-based amusement park attraction in the world. Its drop was . It was the first water-based amusement park ride in the world to utilize an adjustable electromagnetic braking system to control the volume of the splash.
Changes.
Perilous Plunge opened with a harbor-themed blue-and-white color scheme
and with three 24-passenger boats, with passengers held in place by lap bars and individual seat belts. However, after a September 2001 incident in which a guest fell out of the boat during the descent and was killed, the boats were retrofitted with four-point harnesses. Shortly after the incident the ride received a more vibrant color scheme consisting of a green and blue track with lavender-gray supports. After a period of time, Knott's received two new boats with over-the-shoulder restraints. These new boats were drastically different in design and thus created a much smaller splash than the first set of boats. In addition, newer designs caused problems with the lift chain. Stress fractures appeared in the lift chain shortly after the arrival of the new boats. The ride was shut down, and a new chain was ordered. This time, the lift chain snapped (though the anti-rollback device prevented the boat from reversing down the lift hill). Finally, the problem was diagnosed and a new chain was ordered.
