Going Down For The Third (and Last) Time


Obviously, the most top-of-mind danger that all mariners face is drowning. We live, work and play in a marine environment – a hostile marine environment, if one is not careful. And, even if you are careful, things happen. This column is about that.

An Ounce of Prevention is better than a pound of cure so bear the following in mind. First, we must all be wary of hypothermia. The symptoms to look for in others or yourself are the actions of someone who seems to have been drinking heavily – except they haven't been. Clumsiness, slurred speech, poor fine motor skills, crankiness, etc. Actions you can take to prevent getting hypothermic are:

1. Keep dry, spare clothes aboard. They can even be added on top of wet clothing if need be.

2. How'd your clothes get wet? Could be from "working the boat" in foul weather or, worse, you fell overboard. The only thing worse than falling overboard is not getting back aboard! More on this below.

3. To help yourself immeasurably, always wear your life jacket. Inhaling cold water is a killer and that will be very hard NOT to do if you are under water . . .

4. Stay away from booze, period. Unlike the Saint Bernard rescue dog stories, booze doesn't help you survive hypothermia.

He Fell Off The Dock And Never Came Back Up

How many stories have you heard of over a lifetime where a seemingly minor event, like falling off a dock due to stumbling and landing in cold water, results in an almost incomprehensible death by drowning? It happens and it shouldn't. How come the victim couldn't help themselves?

Cold Shock/Gasp Reflex/Dry Drowning

Years ago, while training with my son to be part of a USCGAux Cold Water team, we all received a workshop on a developing understanding of something called "Cold Shock" or the "Gasp Reflex." Scientists and doctors were just becoming aware of why someone could drown "instantly" upon hitting the water. Basically, in water below 70-degrees F, which we are certainly boating in during the early months of the Spring and late months of the Fall, a number of nearly instant and deadly things can go wrong, even if you fall just a few inches from the dock to the water:

So, if you survive all this, then you will have to deal with the potential effects of hypothermia. Remember, despite all our advances in science and technology, our bodies can survive only in a pretty narrow range of internal core temperatures. How about those aches and pains you feel in your muscles when you get cold? A drop of only 1.5 degrees from good ol' 98.6 is all it takes. A few more degrees, say 5 or 6, and you'll stop shivering because now your body can't shiver anymore – there isn't enough energy in your body to shiver, much less climb into a boat or onto a dock. Another 4 or 5 degrees from there and the heart is now struggling to gather enough energy from your internal core to beat.

So, if you fall in, get out!

BTW, if you are interested in being part of USCG Forces, email me at HYPERLINK "mailto:JoinUSCGAux@aol.com" JoinUSCGAux@aol.com or go direct to the D1SR Human Resources department, who are in charge of new members matters, at  HYPERLINK "http://www.d1south.org/StaffPages/DSO-HR.php" \t "_blank" DSO-HR and we will help you "get in this thing . . ."
