So this is a good discussion, thanks for bringing it up. I firmly believe we should all have swiftwater and wilderness first aid as minimum training for being competent life-loving river folks.
First off I gotta say, +1000 for DSE's kayak Swiftwater class. I was sooo whupped after two days on the river with Nick and Evan... The best hands on real world down and dirty,minimal equipment class I have ever done. Geared specifically towards us kayakers, with the kit you carry day to day. as stated we were in and out of our boats constantly, repetition for muscle memory. Nick Had a donated,cracked Hoss that wouldnt make it around a corner before legitimately sinking him...
The caveat to that is that I did their (more ) advanced level class, and I do feel that it was a benefit to my experience in the DSE class, having had multiple previous traditional classes to springboard from.
I think this is the class OP (streetdoctor) is looking for, and has now found...
of course they offer a beginner class too.
Which is what makes the DSE class so special, being pared down and kayak oriented, by guys who have been there, functioning as a qualified team in extreme environments, far beyond my (mere mortal...) level.
For discussions sake, certainly not to be condescending, but the didactic/ classroom stuff has its place. Especially for anyone in the professional or volly Fire/EMS/River/SAR world. lots of shit to worry about if you are talking about anything but clean delicious (lol) river water...
So there is,if i can recall, actually mutiple levels of classes available, for anyone wondering about this.
there is the traditional
Fire/SAR oriented Swiftwater/Flood Rescue Technician class,
there is SRRP (Swiftwater for River Professionals) Raft and kayak specific class,
additionally there is kayak specific swiftwater classes, like DSE's course.
beyond that of course, are technical rope rescue, and instructor classes.
Here is a good description and course info for my local New Mexico based classes.
