Our 34 has a similar issue.  A weeping of a minor amount of water exiting the 
gel coat in the bilge about 4 inches aft of the mast step and one inch above 
the bilge floor.  Hull is solid except for a cored area about 4 feet from 
centerline.  Pending further examination and tests, most likely cause is the 
stringers used to reinforce the sump area for the keel loads.  Seems they can 
separate from the hull interior, allowing bilge water to enter when the boat is 
heeled, and eventually seep through when the boast is upright into the bilge.  
My thought is our issue may be related to some groundings of the past, but need 
further evaluation when things warm up in the spring.  Overall, not a 
structural and more of a nuisance than anything else.  To be continued…..

Jacob,  the C&C 36 hull is cored throughout.   The area around the keel stub is 
solid.   The area to which you refer is most likely cored.

In my '78 C&C 36 I am seeing a couple spots where salt water is weeping in 
through the hull near the bilge area, appearing from seemingly nowhere as if 
from a spring. One point is about 3' back from the mast and 18" to the side. 
The other is closer to the keel but they both are on the edges of hull 
stringers. 

 

I've had a few people look at it and I've gotten everything from an estimate to 
rebed the keel (though the bolts seem fine and I had the boat out in May), to 
cutting apart the fiberglass to locate where the water is running from, to 
don't worry about it.

 

Has anyone had this happen before? How big of a deal is it? The amount of water 
is minimal but I believe they were coring the hulls. Does anyone know the exact 
cross sectional thickness of the fiberglass? Were just the sides of the boat 
cored or did they do the entire hull? How did that work where the keel meets? 
Is it possible that a through-hull is leaking and water is running up to 
several feet along the core and popping up somewhere random where it has found 
a weak spot in the fiberglass?
