When the boat aligns with the yellow grab rails, it is stopped so riders can board. Most of the course is on top of a hill and it uses supports only when the cement trough goes under the lift hill.įrom the Hydra: The Revenge roller coaster exit, you can see the cement trough. What is remarkable about this attraction is the unique split lift where halfway through, it changes angle to align with the top of the course. In 1982, Barr Engineering designed Thunder Creek Mountain at Dorney Park (Allentown, PA). The lift hill use square anti rollback blocks to prevent the boats from slipping backward in case of a ride stoppage. Notice that the runout of the drop goes directly into the water. A steep 50 feet drop is our goal and unlike many manufacturers, the running rails at the bottom of the drop do not raise the boats out of the water.

Large 6 passenger boats are used and a double station similar to older Arrow log flumes is used the eager daredevils. Located at Silver Dollar City in Branson, MO, Jim Owens Float Trip took riders aboard small boats past various humorous scenes such as a tumbling outhouse, a dark cave and through whirlpools.īarr designed a new course that reused some of the existing theming and followed the storyline of riders being daredevils racing to the top of the steepest falls around. In 1981, they transformed the old Jim Owens Float Trip into the American Plunge log flume. This popular attraction was removed in 2008 to expand the waterpark, Soak City.

Barr Engineering first got involved in the amusement park history in 1978 when they were hired by Valleyfair (Shakopee, MN) to design and manufacture a new log flume for the park.
