Re: [Paddlewise] Protection for immersion...

The idea has been kicking around as to how much protection to have in terms
of cold water protective clothing.  There is no real answer especially for
areas where you have a period of time in which air temperatures rise while
water temperatures remain cold.  So you have San Francisco or Lake Superior
(cold water year round, seasonal high air temperatures) or the Middle
Atlantic area such as NYC or DC (transitional periods of cold water, warm
air tempertures).

Products like HydroSkin or Watersports Polartec or Fuzzy Rubber are an
answer as long as you recognize that the cold water exposure protection they
give you is limited to X minutes or so; and, moreover, once you are back in
your boat may leave you chilled (with HydroSkin and Fuzzy Rubber being
somewhat better than the Polartec unless you have a paddle jacket over it).

I think it was Matt who pointed out that the fellow who died on the lower
Potomac recently would have probably died even in a dry suit with tons of
insulation under it if exposed long enough in the water (say that he went
over late in the day and was in the water overnight).

So what are your choices?  Dress for _both_ the air and the water.  Now
before you rush to keystroking a reply, hear me out.  At some point, you
have to concede to air temperature or at least have some provision for
cooling down.

While one can actually wear a dry suit (even a coated one) into pretty high
temperatures (my limit has been days up to about 70 in my coated one), at
such higher air temperatures you do need to vent.  That lets out a dry suit
unless you want to paddle with the zipper open which has its potential
dangers and drawbacks and is not advisable.  That also lets out a dry top I
would think since it won't vent at the wrists.  I have a dry top and never
have understood their functionality unless it is one with a latex neck as
well as latex sleeves.  Most sold today do not have latex necks and would
likely get water trapped in the sleeves in a capsize and seriously affect
your re-entry attempts.  So a normal paddle jacket would do well here worn
over one of those products mentioned in the first paragraph above.
Something like HydroSkin in a two layer setup of a shirt over a farmer john
of the stuff would be pretty good.  You could vent at the sleeves and neck
and if you capsize, cold water would not be constantly flushing in and out
of the jacket in any great amounts as it would not be coming through the
material itself.  This would help the insulation below (HydroSkin or similar
light stuff) work somewhat better.

Wear the full regalia on those cold-water/warm-air days and vent or cool
down often.  People talk about the roto-cooling of rolling.  If you are
confident in your roll and don't mind the shock of hitting the cold water
while super heated from paddling and the warm air, do so.  But, face it,
well over half of paddlers, even those in this illustrious PaddleWise group,
do not have a reliable roll or can't roll at all (I think 80 per cent is
still a good figure for the overall non-rolling reliably paddling
population).  If paddling alone, it is amazing how much dropping your wrists
and forearms into the water will cool you off or that old dip-hat-in-water
routine of cooling off.  If paddling with others, just hang on to their bow
and lower part of your lower body into the water.

Again, such compromise arrangements that would span warm air paddling over
cold water are limited in how much immersion protection they will give you.
You really only have minutes to self-rescue, i.e. maybe 15 minutes or so
tops depending on just how cold the water is.  After that you may not be
functioning well enough to self-rescue.  Obviously in such situations, you
can't afford to lose your boat as you will not be able to swim to shore.
(BTW, it was the other Ralph who talked about having swim fins, which Matt
questioned in terms of where to keep them on you since your boat would leave
with them.  I am of the have-a-helium-balloon school of such quick get to
shore backups  :-)).

The point is that warm-air/cold-water days or season are the most insidious
in their threat.  All you can do is work out some compromise spanning the
two opposites that will work the 99.99 percent of the time you are upright
paddling and the 0.01 percent of the time you might possibly be in the
water.
