My Ericson 39b has encapsulated lead. recently I had to do a repair of an old repair due to the keel being put down on the edge of a sleeper cracking the old repair. what I found was the glass was at least 1" thick at the sides and nearly 2" at the foot. the lead did not touch any part of the skin but was supported all around by large blobs of bog. I could only see the bottom 15" inside the keel the top of the keel is glassed over as is the leading edge of the bilge behind the lead.
Whats "Bog"? Any pictures of the keel and repair?
