Mark, I agree you have a significant leak somewhere, and that some of it 
seems to be coming from/through the sprayskirt.  However, the amount of 
leakage you describe seems excessive for that source, unless your paddle 
puts a lot of water onto the deck with every stroke.

Is your boat equipped with a rudder?  I've chased leaks on a couple boats, 
and another possible source is via the rudder cable channels, if you are 
paddling water rough enough to immerse the cable exits.  It might seem that 
the tiny holes there would not admit much water, but typically the 
"pumping" action of your body motion on the spray skirt deck can actually 
work an enormous amount of water forward.  An easy test of this is to 
securely seal the exits using electrician's tape (small slit for cable 
exit), and then paddle without the skirt for a while, using a paddle that 
does not throw water into the cockpit.  Then switch to your GP and seal the 
deck.  Compare water inside to what happens the way you usually paddle.

If you do not have any exits for rudder cables, then I punt.

Well, there is another possible source:  a leak where the coaming attaches 
to the hull.  This is an easy one to chase:  stick your head inside the 
boat, with a headlamp on, and have a compliant helper spray gentle streams 
under the coaming edge, making sure the spray is not coming over the 
coaming edge.  Move around the coaming and you should see water if you have 
any detachment.
