It's tough to see what the swimmer is doing during a lot of the video, but overall it's a good argument against the "whitewater swimmer's position" in class IV-V whitewater. Trying to keep your arms and legs out of entrapments is all well and good, but if you're swimming in heavy whitewater, your goal needs to be to swim hard to shore. For most of the narrows, your goal is to get to the right shore ASAP.
That was nasty! I know that it is hard, but please don't swim after just your second roll....swim as a last resort! Again, hind sight is 20-20, but in Class V, roll up like your life depends on it (because it just might!)!
It might just be me,but I didn't see alot of aggressive self rescue,just a bunch of "hey buddy still in your boat,come save me!".Being a solid class 4 swimmer,I know the waters cold,and it zaps your energy,but get on that belly and freakin' swim!
He could have been on shore alot faster had he swam a little. By the end I can see him being too tired to effectively swim, but for the first minute or two he had plenty of time to get to river right and out.
