Date: Mon, 8 Nov 1999 12:18:03 -0600
This last weekend I took my kayaking class out for their cold water lesson. 
The air temp high was 45, the water was at 40. And the class seemed to be very 
confident. We paddled 20 miles, mostly with the wind, crossing 3 lakes 
following  the Pelican River in MN.

Everything they had been taught was in the classroom, and a heated pool.
As an instructor, we require a supervised cold water trip to pass the class.

The class (having nearly a semester of lessons) picked out their own equipment 
from the lockers, all their safety equip, and selected their favorite boats 
the group largely honed in on the Scimitars, Shadows and Sea Lions. 
The class was to be graded on everything, total preparedness. We graded them 
on what clothing they selected, having heard a few cold water lectures. As 
well as overall paddle technique, use of the safety equipment and 
effectiveness of their self rescues.

The avg. student selected 3mm wetsuits and wore 1mm wetsuit underwear beneath. 
Nylon swimsuits, polypro sweatshirts, synthetic/smartwool Longjohns. Booties 
with wool socks, fleece hats, and most wore drytops. Only 1 student selected a 
drysuit.

At the end of the long paddle, students have to demonstrate their 
self/assisted  rescue skills. They had to show at least two. Both could be 
self, 1 had to involve a wet exit.

The results, advanced students overwhelmingly agreed it was far better to roll 
than to wet exit. An appropriate response.
The weaker students found they were only able to roll in the pool. Giving 
comments like "I was under, setting up for a roll and I thought my head was 
going to explode from the shock".
Only one person did a paddle float rescue (drysuited). He didn't care what the 
weather was like, he was just fine. The rest settled for the "quick and dirty 
T-X rescue/pump/ get me the hell out of the water theory".

I noted an interesting difference between paddler sizes, I believe corelated 
to body fat. Comparably dressed larger "corn fed" males were easier to deal 
with in the water. They clambered back into their boats needing little 
assistance. The smaller, ahem, "petit" females were typically short of breath 
and close to a cold water induced panic. The females in question were arguably 
in "better" shape (track runners) vs the pudgy lineman males. Yet the males 
were calmer, and able to pull off more difficult rescues: Reenter/roll, etc.
 The females did have one advantage, being lighter, I could grab them and help 
pull them across my decking. so they could reenter their boats.

This leads me to question...
This difference directly compares a book I am currently reading: Peary's 
documentary about his trips to the North Pole, written 1890-1905. Peary 
compares body types of the ideal people for this trip. He notes how Eskimos 
are ideally suited for his expeditions, they are very strong and thick with 
body fat.  
In this day of get slim, and stay strong, I wonder are we neglecting our 
bodies need for an appropriate layer of fat? 
Without all of our technical gear, could we survive a freezing cold night 
sitting on the side of the river waiting for help?

Just because we regularly practice cold water safety, can we really survive if 
we need to?

I can only hope that my kayaking class learned the message of how dangerous it 
can be paddling unprepared. They were prepared, and experienced first hand 
coldwater immersion. I know that they will think twice before traveling on 
cold water without the proper gear. After some hot chocolate, ( a thermos in 
every boat) they were back in cheerful spirits.

I hope fellow P'wisers practice their cold water as well.
I plan on asking my doctor about my fitness, suitablility for cold water 
paddling.
If you are an MD, please read on.

I guess the reason I am so concerned about coldwater is that I do live in MN 
as the saying goes the water is either frozen or getting there. I live here, I 
paddle here, I should be prepared for life-here.
I had no problems in the water, should I worry about that little layer of body 
fat? If I lose it will I be noticeably colder? My BMI is a clean 22. The 
charts say that I am at the upper limit of healthy people. 
Pro's and cons of lowering body fat?

Ratio of surface area vs mass.    Higher mass gives higher heat generating 
potential, ie, more muscle tissue flexing and burning those carbs.   Add a 
wetsuit into the mix, and a stocky guy like me (5'8", 210lbs, 38" waist, 45" 
chest) can break a sweat under heavy exertion even in pretty cold water.   
Of course, this doesn't prevent that shocking sensation when you first hit 
the cold water.... vavavavvavavavavavavava

I could, and have.  Though sitting is unwise, stay active and you stay warm.
Push ups work good for me. Sit-squats would also do good..

The charts and definition of "healthy" are medical things.  Usually 
measured by mortality rates.  IE, if body configuration A lives longer 
than body configuration B, then A is healthier.   No accounting is taken
of whether "B" can lift three times the weight "A" can, or whether "B" could 
swim a mile in 48F water and "A" would get hypothermia and die before 
even making it half way.

FWIW, I don't object to folks who want to measure their health against a 
mortality table; as long as they don't object to folks like myself who 
couldn't care less about maximizing life span.  [I could rant on this for a 
while...  gak!]

Most marine mammals and penguins are equipped with a solid layer of blubber
that retains body heat (and provides bouyancy).
BTW, Alaskan eskimos (noted by Peary to be ideally suited for his arctic
trips) eat blubber (even Crisco mixed with wild berries and sugar... "eskimo
ice cream").
Seems reasonable to conclude a lean person would feel the effects of cold
water sooner than a fatter one. I recall studies suggesting conditioned
swimmers have a higher subcutaneous fat content than other athletes... the
distribution of fat being regulated by the body to keep the swimmer warm.
It's been a while since I read that, but might be something worth checking
if you are interested.

You bring up an interesting question that I see all too often, atleast 
from where I stand, on this list.

Why does all this great training stop here? Don't get me wrong. I think 
it is great, but think it should go a step or two more.

You mention the proper gear and all, and how differant types of people 
react to the water temps. It is also drilled into everyones minds that we 
need to carry proper equimpment on our PFD. Agreed with here. However, 
wouldn't it be a good part of the training exercise to have AT LEAST SOME 
of the people see if they can use what they carry with them to, say, 
start a fire(loads of fun with cold fingers, even if you're good), maybe 
show that they could signal for help, or tell someone where they have 
washed up on shore.
I notice that most of this training that is mentioned assumes that you 
can roll or get back into your kayak. That or just having XYZ in your 
PFD. That I feel is a good start, but real false security. 

I don't know about where you all paddle, but even on these inland lakes 
that I spend my time these days, even if I could call 911 the moment I 
had a problem, it would likely be several hours before anyone could get 
near me. Maybe with the population centers most paddle under there is a 
faster rescue time..?

You wondered about sitting all night waiting on a rescue and how you 
would do. Why don't you test yourself. Better yet, prepare yourself so 
that if it ever happens that you can amuse yourself, with thoughts of 
your goofy screw up, and the ridicule from your paddling buddies. 
Spending the night out without a tent and sleeping bag doesn't have to be 
a life or death situation, but it needs to be planned and practiced. I've 
had the dumb luck to fall through "over flow" ice up in AK and spend -30+ 
zero night after that. My only concern was that my wife wasn't worried 
about me, and that all was OK back at the cabin. Lucky to survive? There 
is no luck at those temps, (well some)just planning for the worst.

I guess this all leads up to the question. Why isn't this part of the 
training?

Something you might think about for the next class.

Can you give some more info on this?  I don't like liver, yuck, can't say
that I hate it but its close.  Since I'm not dying to run out an try this
new culinary experience of Seal Liver and I'm sure the local SuperMarket
will stock this wonderful item, is this stuff really deadly to us
Southerners?  Is it good wrapped in bacon?  How is it prepared?

Do we really wish to know the answers?  8-)

Thanks...

This reminds me of when Maligiaq, the Greenland kayak champion was in
the Big Apple for the paddle around the Statue of Liberty.  He would not
do any of promised rolling demonstration until he got some beef jerky to
chew on (The Boathouse had run out of seal meat).

We quickly arranged for a beef jerky run to a local deli and this turned
out to be the scariest moment he had in the States.  One of our members
drove him in a beat up yellow jeep across the highway, probably going in
tne wrong direction and bouncing him through the steets of the Tribeca
neighborhood in which the Boathouse is located.  Maligiaq looked ashen
on his return and for the rest of his stay kept talking about that scary
ride.  I scared him a bit when I drove his hostess's Jeep Cherokee
around the city during their stay (she was wary of city traffic).  New
York drivers. :-)

i'll bet that was funny ;-) we got stuck in a traffic jam driving him home
once, and he said there were more cars in the jam than greenland has ...
he also said they can't get their drivers license until they're 18. there
aren't many roads there either ;-)

Friends,  if Eye have to eat seal liver or ANYTHING's liver  to survive
cold water ...well, this good, ole boy will just stay ankle deep in his
swamps and bayous down here.  Heck, my main paddling season is just now
getting started.  Most of the really mean mosquitos are dead;  the night
time temps are low 40's with high 70's during the day;   day paddling has
now become truly enjoyable and not just a field exercise in avoiding heat
stroke or heat exhaustion.    I have a thermometer left over from the
swimming pool days, so I measured the water temp last Sunday before
leaving the put-in.  I'm not even going to tell you what it read, but
about 45 minutes of paddling has me doing the "stretch and switch"  with
poly underwear to wind up with bare skin under my PFD ( ...yes, always !)
  

I have tried to eat liver and will take my chances with the coldest of 
water any day.    My mother-in-law (  a wonderful Cajun Momma, God rest
her soul ...)  once told me she could cook liver and I would not know it
was liver ...SHE LIED !   

In conclusion here ...if I tump over in cold water ( ...which I have done
!  ...hey, it was at least pretty cold in THAT February  ! )  I know I
have a better than average, fighting chance of making it okay.   With the
liver ...well, just go ahead and divide up my gear !

...adieu   ...Peyton  (Louisiana)

        Recently I read something about the disastrous consequences of a
ballooning expedition to the North Pole which was badly outfitted and
planned..  It was the one that Amundsen died while trying to effect a rescue
of some of the personnel.  The last group, with the balloon, had landed on a
huge ice floe somewhere up there.  By the time rescuers reached them they
were all dead, not from the cold but from having eaten the livers of polar
bears they'd shot for food.  Recollections are dim now, but I recall that
these livers are loaded with one of the vitamins, such as D or E which in
high concentrations are fatal, but the victims didn't know that......
        Anybody else remember this?

Not that story, but I have heard that Vitamin A concentrates in polar
bears' livers since they're unquestionably at the top of the food chain
up there. Saute up a nice slice of polar bear liver with onions and
bacon and poof! yer dead of Vitamin A overdose.

Of course, if I had a whole bear to eat, I'd probably start somewhere
other than the liver.

Polar bear livers are very high in vitamin A, which is one of the fat-soluble vitamins; in high doses it is toxic and even lethal.

If I met a Polar Bear, I would probably not be the one ending up with
dinner.

Yes, indeed.  I'm sure polar bears are partial to rabbits, especially if they 
are a matching color.  :)
