I read about it years ago and fitness likely is a better predictor of 
short term survival ability than long term (as Ari suggests).  Once any 
person is in the water long enough (where long is very few minutes) the 
outer extremities are shut down and then insulation is important.

However, as Prof. Popsicle (Giesbrecht) and others have pointed out, the 
ability to control yourself and deal with the situation in the first 
seconds to minute is critical to long-term survival.  Again, as Ari 
pointed out, it likely will make a difference for a paddler in the 
period when they are attempting to re-enter the kayak.

I've been contacted back-channel about my comments on fit vs fat.  I did 
say fit vs fat, not skinny vs fat.  Fat _and_ fit will outperform skinny 
and way out of shape.  Fat levels don't strictly dictate fitness (though 
extreme overweight and obesity pretty much preclude fitness).  If you 
compare runners to distance swimmers, the swimmers almost always show 
less muscle definition due to a thicker layer of fat on their bodies 
(the muscle is under there, just not as obvious as in the 4-8% body fat 
athletes).  If you spend that much time in the water (even in heated 
pools) that little bit of fat is beneficial.
