you raise an intersting thought here, it is one that i have gone over with
bill hamilton a few time over the past 15 years at different times. years ago
when we only had the navy tables many of us (independently) came to the
realization that the hangs on deco had to be longer & later we realized that
they needed to be deeper as well. these adjustments seemed to save us from
many of the major & minor hits (skin hits & elbow & sholder niggles) that many
of the divers were getting. ther has always been a number of divers that
thoght the extra hang times were ("wennie") but i must say that it worked.
many of the divers had the interest in trying to shorten the hang times as
much as possible (with the obvious goal of remaining free of those niggles).
what has happened is the length of the dives has increased dramatically &
until we got into different gasses it the hangs limited the bottom times (for
us). now you are raising the point that at 280 for over 30 min you resulted in
some injury. well your response was to get into better physical condition to
"adjust" yourself to fityour dive profile. i find this totaly acceptable &
realize that it will work until you get to a depth & or time that pushes the
dive beyond you conditioning. at that point i am sure you will come to the
conclusion that you will have to make some other adjustment, longer hangs -
shorter dive- different gas. whatever it takes to accomplish the dive is what
you will do.
we have all agreed that your premisses for the most part are probably true
regarding the fatty tissues. so all of us either overweighted or out of shape
or older divers have made there adjustments. it seems to me that it is all
relative. i have always been willing to make my dive fit the circumstances &
from the dives you guys do you are doing the same.
it really is a different ball game from diving warm water to diving cold
water. you know from our conversations in the past tha i'm not into the chest
beating stuff about better or worse. different is just that & nothing more.
you guys have the opportunity to stay in(out in some casses) as long as you
like doing your deco's. we don't have that luxury. you guy's don't do 2 - 4
hrs in water on your open water dives, we do.
all of these things create the challanges that we need to overcome & it's what
make this sport so great.
we have people of all sizes & shapes doing the dives all over, should they be
excluded from doing what they want? if they can make the "adjusments"- lose
wt, get more fit or extend there deco time & change there gasses- & reach the
point where they do not get bent who has the right to stop them or castigate
them? at that point we are all at the phase of having fun doing what we all
love- we are just doing it a little differently.
we are all doing what apparently works for each of us, IMHO that is the bottom
line.
see you at BTS.

Mon Cher Capitaine,
Kevin Gannon didn't " may have gotten it wrong". He purposely wrote his
little snippet to discredit us and antagonize members of the WKPP. He
comes right out and states plainly that we have an obvious "hidden
agenda". Our agenda is not hidden. We are right up front about our
commitment to the "Doing it Right" credo. So far "Doing it Right" seems
to have a pretty good track record compared to what else is out there.
Do you not agree?
As for talking to people, I believe we know how to do that fairly well.
I think the 80 or so individuals who attended the WKPP Indian Springs
Seminar on February 28th seemed to comprehend the many positive and
informative messages which were put out.
Let's face it. You've taken something of a beating of late on this whole
issue of physical fitness and decompression, beginning with Dan Volker's
comments on VO2 max. Frankly, I must applaud your honesty with regard to
coming out and admitting your physical indisposition.
I am sure you are a pretty nice guy with plenty of friends who will
attest to this fact. It tends to come with the territory of being a dive
charter captain. Still, based on my own experience and that of many of
my WKPP colleagues I can tell you flat out that you are in for a serious
physical beating the moment you attempt to pull a mixed gas exposure
exceeding 30 minutes (time on the bottom) at 280.
Decompression is very much a function of cross sectional area and
microcirculatory perfusion. Thick concentrations of body fat are poorly
vascularized and must be decompressed very carefully. In fact, my guess,
is that you simply cannot properly decompress severely fatty tissues
without significant capillary blockage and subsequent damage. The DCS
type 1 symptoms to bulk fatty tissue are not very pretty and approximate
a crushing injury. The first time this happens to you, and it has
happened to me (and I have relatively little body fat and subscribe to
the Dan Volker school of fitness) you will be signing up with an
aerobics program at your local gym.
All of the guys in the WKPP will gladly share this information with you.
Just ask nicely, publicly or privately.
Best regards,
Bill Mee
