I would kayak Cumberland River but I've kayaked a lot. That can be a dangerous River. Very cold and can be very swift. Also to stay in one spot, an anchor works pretty good. The pedal kind are great, and I'd buy one too, but now if I'm going to large water I take my bass boat. Still would buy a cheap paddle type to see if kayak fishing is for you. If you really like it you will want more than one anyway. You will want to take your family and friends and extra kayaks come in handy.
