@Wayne I am am with you on your points about being incapacitated. My wife and made a decision years ago to stick with USCG type vests due to exactly this. We ski on public water, usually "poaching" as we say, which means we have no observer. It occurred to us that if one of us, especially me, was unconscious dead weight, the other would probably have a tough time getting you back in the boat. I think a comp vest would be great under any other circumstances.
