Hi GC Guide,
I've only got nine trips down there -- three of them rowing a 20' cat -- plus quite a few Cat, Deso, and Westwaters. (Living in the Midwest is a drag, but I still get to go to fun places.) So from a guide's point of view I might be considered short on experience, or perhaps my boats are too big to use the rowing technique being talked about here.
Sure, you can push through a line. But if you're in the middle of the Colorado, 25 yards above the meat of the Ledge Hole, at 20-25k cfs, unless you're in a very light fast boat, all you're going to do by pushing is speed up arrival at the scene of the carnage.
Ormaybe we just have have a terminology problem. Cautious guy that I am, I regularly go onto rapids rowing backwards, at an angle to the current, to move laterally in order to avoid obstacles downstream from me. And that's sure what I would have been doing here to avoid the Ledge Hole. If I errred in calling it an upstream ferry, I apologize for the confusion.
