I am drifting a Class I river (Lower American, Sacramento) in my Renegade a few times a week, and I'm new at drifting with a pontoon. I would like to be able to row upstream some, especially after a sort drift down to fish a hole, and even in fairly moderate flows can't do it well. I understand ferrying and eddies from kayaking. I do have the stock Scadden oars which aren't much. Would a better set of oars make that much difference, or is it that by design pontoons just don't do well rowing upstream?
