I've never used my tube in anything but moving water. While I wouldn't shoot any ugly class III or higher rapids, I have gone through I, II, and III(rated, not actual, in my opinion). If you can wade it or swim it, you can tube it(but you should be very familiar with the water). I know that most years, people(drunk rec tubers mostly, but occasionally kayakers and waders) die in the area I tube. If you use common sense, and portage around the really rough spots, all should be well. I think that the recommendation to not use a tube in moving water is a liability issue more than a safety issue. BTW, no craft type restrictions on my waters, other than a PFD must be worn from Nov-April
