One of my pet causes is the inflatables. I believe that if I fall out of my boat there is a decent chance of hitting my head on something on my way to the water. There are two scenarios, the first being, buy the auto inflate because you may prove me wrong and if that happens give me a call to gloat about how much money you saved. If you do hit your head just pat yourself on the back when you come to. Secondly, it is really easy to put one on inside out, this moves the cord to the other side of the jacket and if you hit your head or even if you are panicked it may be the hardest problem you never solved when you can't find the cord. I try to remember to have everyone locate the pull cord when they put on the inflatables in my boat so they know where it is and if it is on correctly. Buy the autos.
Just one of my ocd symptoms.
