Recently got this boat, haven't got on the river yet but I can't wait. Paddled it on a few flatwater trips and I love it. Faster than I expected in the flat, but it does take constant attention to keep it straight.
I turns on a dime if you ask it, even easier than my previous boat (16' Nova Prospector). Got to get out on the river and see how it handles the waves. My only concern is that the hull seems somewhat more flexible than I'm used to. Personally I'd be happy to trade 6-8lb for more rigidity, but I'm big enough to carry that too.
