Hans, in my honest opinion..........I think you are right on! Of course the disclaimer is I've been a professional rescuer serving a community for over 18 years where safety and "risk to benefit ratio consideration" are a daily walk of life.
With that said: statistic alone say you are right on the money about staying in your boat. It is mere fact that survivability
is dramatically increased when you stay in your boat until you can no longer effectively use manuever to "right" yourself due to exhaustion or other. Sure sure....some of you will disaggree with that because we all know atleast one exceptional story of "oh this guy would have drowned if he didn't bail on his boat" much like you hear those stories of: "oh the dude would have lived if he didn't have his seatbelt on" but sorry statistics tend to strongly suggest "staying with your boat as long as you can until all else fails, dramatically increases your survivability".
Thanks for taking the time to share "Lessons learned" we do that in my profession and it saves lives! Too often people wouldn't share and move on to just reading the other forums. I thinks its our responsibility to humanity to watch out for our fellow boaters.
Thanks again and bravo.
Happy safe boating this year!
