I am in the process of having my keel redone...grinding out the keel joint, re-fiberglassing and fairing. The guy doing the work for me noticed that when the weather warmed up moisture started to seep out at the trailing edge of the keel, which of course would indicate that water will go the other way when she's in the water.

Has anyone else had this issue and know what causes it, a hard grounding at some point in that past maybe? My boat has moisture up and down the entire starboard side, and I'm thinking that this is probably the major source of intrusion.
