The thing to have if you are going to be on water, especially cold water is SOSpenders the kind that inflates as soon as you hit the water. They are light weight and you really don't even think about them when you have them on. they are perfect for hunting because they are not as bulky as regular PFDs and you can shoot while wearing them. I wore a set when I helped a friend bring his 42 ft sail boat back from Bermuda to MD. I wore it for 6 days and We hit a full gale a half a day out of Hamilton and were in it for almost 3 days and I wore it all day and night. They cost more than the standard PFD but they are worth it.
