Flipped a boat one time dude. What you need is big water, to start out. Or summer flows. The Boge not a bad river. But things change every rain, sand bars, log jams,sweepers, got to be on it guy. I never do a river till been on it with someone that has been on it befor!!!! Seen a boat flip in frog water going around a sweeper one time. Do it in the summe or in the spring . If things go bad you walk. And if you are good you will find the cuts. And won't have to drage the boat to far. It,s all fun just be safe. Always!!!!!!!!!!!!!
