The rubber skirts and steel running rails are seen after the drop.Īrrow at first only offered the log style boat, but at customer’s requests, came up with more models. A small pump take water up for the show water on the drop, but what is remarkable is that after the first lift hill, the water in the channel goes uninterrupted until the bottom of that same lift hill as the channel continues under the second lift hill. This 1967 installation is a compact model where the park large lake serves as the reservoir for the ride and only one set of main pumps is required to run the ride. This picture shows the Pitoune at La Ronde (Montreal, QC). Arrow started with 30 feet drops and then eventually designed 60 feet tall drops on flumes. Small drops can be included along the way and then the final drop was usually the biggest. 40000 gallons a minute pumps were used for example on the defunct Log Jammer at Six Flags Magic Mountain. Large water pumps were used to take the water to the highest level and then it flows down. Both pictures appears courtesy of The ride use rubber conveyor belts to move the boats up the lift hills and then, it float down in a calculated way where the water level stay constant and the speed as well. Of course, the guests were unhappy as they came off the ride bone dry, so the same managers would go back to Arrow and ask them to put it back to how it was originally. Many park managers used to test their rides wearing suits or dress clothes and who like to get their jacket soaked? They would then ask Arrow to raise all the skirts and make them so wide the boats could barely go through the middle. Also, to control the wetness, rubber belts are present on the side of the rails and the height and size of those belts ultimately decide how wet riders will get. The water in the runoff acts as a brake and creates the splash. In addition, the boat does not float at the bottom of big drops. The front of the boat has a scoop to project most of the water away from riders.
It brought record crowds to the park, although park management sometimes struggled with the wetness they expected guests to feel. Cedar Point (Sandusky, OH) also bought one shortly after, but it opened after “El Asserradero” (The Sawmill) at Six Flags Over Texas.Įl Asserradero opened in 1963 and was an incredible success. It replaced an attraction where guests travelled a trail in the woods on top of a mule and thus, Arrow could design a long layout that would effectively showcase what it could do. Angus G Wynne, the founder of Six Flags Over Texas (Arlington, TX), was the first one to sign for the Log Flume. In 1962, after building crude waterways out of plywood, Karl and his team had discovered the formulas that would allow him to design a constant water level in his designs. How much water is needed? What is the proper slope for a constant boat speed? Where can a small turn be added to create a thrilling rapid? Karl Bacon wrote the book on that and he can be considered the father of the modern water ride. He used Navy research to properly understand water flow and thus, created the perfect water attraction. Karl Bacon (he had founded Arrow Development along with Ed Morgan) started studying Hydrodynamic, which is the science that explains and control the movement of water.
River Caves is more of a dark ride that features a small lift hill and drop at the end.Īll those rides were popular, but the physic of water was not fully understood. The velocity of the drop is what pushes the boat toward the return channel and it is a very simple and reliable idea. In the case of Mill Chute, it features a long float in a dark cave before a lift hill and dive into the natural lake. A few examples of remaining Old Mill/Mill chute in the world are Mill Chute at Lake Winnepesaukah in Lakeview, GA and River Caves at the Pleasure Beach in Blackpool, UK. They were also called the “Tunnel of Love” and is referred as such in many books, movies and video games. Those rides consisted of wooden flat bottom boats that floated alongside either a dark tunnel or scenery before concluding with a small wooden lift hill and a dive into the water. The Log Flume attraction first debuted in 1963, but it was an evolution of the classic old water chute attraction that dated back to the early 1900’s.
