I have been considering this especially while singlehanded and thinking about getting back inside
lifelines with a fully inflated/tethered
PFD. IMO, you also have to think through your own specific scenarios such as whether you'd have capable crew on board, typical
water temperatures, how far
offshore, the ease of getting back on
boat, survival potential if in PFD versus no PFD. Then make your plans accordingly. This sounds morbid but some people claim that another reason for wearing a PFD is it's better for finding a body than without. Just another one of those things to think about....
