Generally, I do not use flotation bags in standard CI situations, although I do have a couple of sets of bags for dedicated whitewater boats. However, I have been re-thinking my use of them and will probably start including them in certain situations. For instance, I may take some in my Phoenix or Starfire on the Buffalo River next Spring, simply because I’ll have the space, and because my boats are pretty enough that I don’t want to risk catastrophic pins if I somehow happen to go for a swim. They significantly reduce the risk of a wrap. I also would like to go out on the “big” rivers near me next year (Lower Missouri and Mississippi) in my Polaris and I may bag it to make re-entry easier, just in case. Also, having the extra buoyancy to cling to if a barge is passing anywhere in the vicinity would be appreciated I think. Recently a kayaker on the Mississippi down here got swamped due to a boat starting its engine too close and the sudden wake flipped the kayak unexpectedly. He thought he was far enough away, but it turned out he wasn’t. That being said, I don’t think most of the MR340 racers use float bags and are normally just fine without them. I guess I just figure if you have the room, why not? It’s not that big of a hassle and it’s fairly cheap insurance.
