edge

Hi folks. Still shopping for my next Ericson. Two for sale locally have a near identical cracks along the top aft edge of the transom... you can see a few pictures of one here. I found a description of a very similar problem here. Some exerpts below. Does this sound familiar to anyone...

Good morning sailors, Attached is a photo of the cracks I found in the deep fin keel of my 1980 E38. Has anyone seen this before and have any idea what causes it? Has anyone ever had a keel crack repaired? It took a day or so out of the water, resting on the keel, before I noticed the crack...
