Okay, here's one for the serious troubleshooters among ya: Last Sunday, when I was retrieving something from the starboard forward cabin settee panel, I noticed it was a little damp. Hmmm, I thought. That particular part of the storage area was bone dry, but the item had been shoved quite a bit forward. I then went to the storage hatch under the V- berth and opened it, finding about a half gallon of water lying there. I cleaned it with a towel and then immediately poked my head and fingers into every crevace and cranny looking for some kind of leak; but found NOTHING. Not even a drip. We sailed back to the marina that afternoon and, before leaving the boat, I checked the hatch again. Nothing. But, the next morning, I came back to the boat to clean it and found about two cups of water. Searched everywhere but found no leak. Going through the process of elimination, I caulked the thru- hull leading from the sink drain; caulked the sink (since there was a tiny little stream running under this side of the storage and a puddle of water also under the ice chest (not the chest itself, but between the hull and the sole). Dried it all out and waited and waited and waited. No drips. No drops. Nothing. Just checked it again today and there was about a cup of water. No drips. No drops. Nothing. Cleaned it. Waited. Nothing. I'm at a loss. Right now, I'm to the point of thinking: a) it's somehow leaking through something when I wash down the boat (but NOTHING IS WET) b) it's seeping in through osmosis c) it's just condensation from humidity (although someone with the exact same boat is just across from me without the problem) d)it's just plain magic Sorry so long, but wanted to put as many details in as possible. P.S. There isn't any water in my water tank. I drained it to make sure it wasn't the problem
