I believe that Krazy is right, Buzzsaw Falls is called a liquid coaster and so is Journey to Atlantis. They are made by different companies and JTA is more flume than coaster while I think BF is more coaster than Flume. There is also another type of coaster that some consider a liquid coaster. I don't remember the name or which park it's at, although I am definate that it is at a Paramount Park. It's built by Setpoint and seems rather tame but you definately get wet, mostly from fountains and squirt guns, etc... Lastly, Schlitterbahn is a water park right? Isn't the master blaster just a raft ride with jets in areas to shoot you up hills? Just curious to know if this can actually be considered a "coaster".
