I couldn't agree more with TIMBAR. I am an accomplished swimmer and wear a life jacket; you never know what you are going to hit. If you cant swim, that means you may have to stand up...in boggy muck...it is very easy to lose your balance trying to walk in it and your feet are stuck. Jonboats may not turn over easily, but please walk crouched for a low center of gravity with feet wide apart)better yet, dont stand up.
