Water Coaster questions

Couple of questions about water coasters:

1. How does the blocking work? Is it like coasters with block brakes, or like on a water ride?

2. Why isn't there many water coasters around the world? Just look at how nice Poseidon at Europa Park looks. They aren't overly expensive and can offer a thrill like no other coaster or water ride. Your thoughts?

When the cars are on the track the blocking works like a normal coaster. And when it's in the flume section it has a flume ride block system. At least it's how I think it works, not sure though.

Rome wasn't built in a day to answer the second question. But I think Mack's water coasters are doing very well for the moment. Their latest water coaster SuperSplash at Tusenfryd just opened and they're currently constructing a Poseidon clone at SaigoMax park in South Korea. And next year or if it was 2005, the other Sea World park will open the second Atlantis water coaster.

I know that Buzz Saw Falls (The world's first water coaster) Does not have a single block break in the ride (Unless there is one under the water after the big drop, which I dont think that there is). Scratch that, there are breaks on the actual coaster part right before the lift. The transfer from Water-to-Coaster is a very smooth operation on BuzzSaw Falls too.

On BSF, it is just one continus (sp?) circuit which works very well for the coaster. In the first part of the ride, it is all water, like a rapids ride almost. Then there is the convesion to the coaster. After some actual coaster ride, there is the lift, then the drop. After the drop, the "johnboat" is still on tracks all the way back to the station.
