Question Keel leaks

We've pulled our 38' Kadey-Krogen cutter as a result of a too close contact with foot long bolts hidden at water level in our marina as a result of Hurricane Wilma damage to the floating docks. The boat has been out of the water for almost four weeks now and we've just noticed a couple of small, pin-point like ruptures through the new bottom paint with stinking water oozing out of them. The yard "experts" are telling us this is just a consequence of a 1986 figerlass hull being out of the water and gravity forcing all moisture into the keel (boat is actually a dual centerboard boat) and not indicitive of any real problem. Question to the experts: should I wait till the hull is completely dry (not oozing any moisture below the water line) and do a final grounding/sanding of the spots and repaint them; is this an indication of a much larger problem; should I put the boat back into the water and enjoy what time we have till the hurricane season kicks in??

DeepFrz is an unknown quantity at this point
this is a serious problem. You should talk to some local experts in this area, but in the least you should have a surveyor look into the problem.

The yard workers may be trying to protect themselves from liability.

Hey, if water is leaking out, it will leak back in again when under hydrostatic pressure. I could result in delamination etc...

good luck
Phil

Osmotic blisters ????

If so it is not good but is seldom the end of the world and likley no know cases of catistrophic failure.

Dig out the void and look at the extent to check that it is a 'pocket' and not a wide/far ranging delamination.

Get copy of west system epoxy's pamphlet on blisters and repairs. It is cheap, comprehensive and published by well know and well respected folks. LOTS has been written on blistering.

If it not blistering but a delamination/structual issue (probably unlikely) then start by surveying with a plastic/wooden mallet and sounding out the void by tapping.

Luck to you.....
