[Paddlewise] PFD Fit and function.

The question of PFD "fit" has recently been introduced.  Here is
a consideration.  PFDs provide flotation only when they raise the
center of mass of the paddler.  Extreme example:  A large balloon
on a long string attached to a paddles helmet provides no useful
buoyancy although the Coast Guard may have rated such a device
with large figures.  

Many paddles wear PFDs that ride up off their shoulders and even
up to the ears.  The buoyancy of such devices is compromised. 
Children's PFDs all have crotch straps to prevent just such an
occurrence.  Our PFDs all do too.  The use of a crotch strap
requires wearing spray skirts over our PFDs, not under them, but
the added flotation is obvious in our self-rescue practice.  The
PFDs stay in place and add the full measure of buoyancy.  So an
alternative to ever shorter and less adequate flotation might be
securing one's PFD firmly down on the shoulders with a crotch
strap.  PFDs fit in this way also remain snugly around the torso
and provide better insullation/hypothermia protection than ones
that are loose floating upwards.  BTW we use the form fitting
segmented SEDAs, extensively modified with pockets for extras --
matches, flashlight, water containers, radio -- and extra
flotation options.  These are so comfortable they are worn often
for continued periods after landing.  

Happy paddling.
