Re: Stus-List weeping hull
Update... I really appreciate your replies and insights. I'm a new sailor and this is my first boat! Took the boat to the yard. Before they pulled her they took off the the aft most keel bolt nut (it was nearest the stringer that was showing greatest weeping) and water start seeping. Pulled the boat but it was right before Thanksgiving and they all took off for 4 days. I'm a brand new liveaboard so a tree house was my new home. There was clearly a crack in the seam of sealant between keel and hull for about 10" from aft and forward. They cut that sealant out.. Drilled a small hole at an angle to that last bolt from the top. All glass. They also cut very small triangle of glass near the bolt and decided there were areas of air in the glass amongst the stringers and thusly the keel boat needed a much larger washer for support. They made 1/4"x 3"x3" plate as a washer. They also pumped grease thru their little hole to displace any moisture. The obvious and most accessible of the 3 leaks water they ground down smooth and bilge painted. They filled the gap they exposed between keel and hull with 5200. Bigger gap than I imagined there would be. Allegedly slapped some bottom paint over that but they had the boat back in the water before I got back from work. Spent several hours trying to sail in light wind and motoring to get home. Checked the bilge and yup...problem not solved. Like I said, they painted over 1 of 3 leaking spots. The other 2 are still leaking...

Re: Stus-List weeping hull
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…..

Re: Stus-List weeping hull
Its definitely not the case of “don’t worry about it”. Do you know if you have balsa? On my 38mk2 from 1977 balsa goes all the way down to the keelbolts tabbing. You need to find that out. Few ways you can do that. Tapping with a mallet on the outside of the hull around the questionable area could give you some ideas if the area is hollow (balsa is already decomposed). Cheap moisture meter(home depot) can be used to see if area is wet but you have to “Calibrate” it. What I mean by that is the following: since cheap meters are not designed to penetrate bottom paints and fiberglass to show wet core, you need to see what the meter reading is on a known “dry” core, and on a known soaked core. Then knowing this, you can see if the area you are suspicious of is wet. But weeping is never a good sign. If you find it wet, find the edge of where wetness ends and you need to drill some drain holes (from the inside of the hull). I am dealing with similar on another project boat I recently purchased. I found cheap moisture meter to be reasonably reliable on a masonry setting. In my case when a drilled suspicious area with a 3/16” hole from the inside of the hull I got a stream of water pouring out. A stream that was in one case initially shooting 3” high when I first drilled it. Good luck.

Stus-List weeping hull
