Hey Pete, do you feel that ferrying is effective for swimming in situations like this?

I must admit to no SWR training - I plan on rectifying that this summer. However, the statement you quoted was taken from experience. I haven't found an upstream ferry angle effective in getting me out of danger while swimming in class III-IV whitewater. Even in my kayak and assisting a swimmer to an eddy, I found the added drag of a swimmer rendered ferrying less effective than paddling straight toward shore. Would you disagree?
