Here's the only pic I could find of "The Drop" (this ride has 3 drops total!):

The only image I could find of Hafema's whirlpool element (wish someone would build one of these coaster/rapids hybrid here!):
I've read a lot of accident reports that are required by some states, and the rapids ride is right up there as one of the kings of minor mishaps that could put a damper on your day. And it's not boatflipping that is the problem. The main problem is people bumping their heads and other bodyparts into each other due to the turbulent nature of the rides, so there could be a reason for those seatbelts.
As for really wet Intamin rapids rides, TNCoasterman, check out the rapids ride at PKD. Holy crap do you get wet if you're unlucky going through the grand finale in the shed. There are two long water curtains (one on either side). Another really wet rapids ride is Roman Rapids at BGW. The statues are not your friends:) And while we rode the rapids ride at Hersheypark on a generous day, on a normal day there won't be a dry person on the boat due to three water falls in a row around the back section by Roller Soaker. An oh, it happens to travel right under Roller Soaker as well and if its effects are on, you're going to get wet.
I still say the most brutal rapids ride I've ever been on is Thunder Canyon at Dorney Park. Who was the sadistic person who came up with that one? It's just one waterfall after another, after another, after... At least you can ride in your swimsuit.
Also, I just read that Intamin is doing another rapid ride in Europe. This time in Germany at a park called Ravensburger Spieleland. Should be 400 meters long (1300-1400 feet) and will also feature a drop AND a whirlpool! Name is "Alpin Rafting".
A water park named Etnaland, located in Sicillia, built a themed Hafema river rapids ride. Smart move! Your guests will be happy when the ride soak them to the bones and you got a ride with great PPH, which is always lacking from water parks (except lazy river, action rivers and wave pools). By chance, a friend sent me a link to a great video showing the ride:
