While waiting for the epoxy to do its thing yesterday I scraped the bottom paint off of a couple spots at the aft end of the keel just above the rudder strap (see pic one.) What I found was interesting and perplexing (two feelings I have often these days working on A-24) at the same time. There is a purple substance that I have also found a few other places on the boat filling what appears to be a hole or something. This filler material is extremely hard. In the center of the material as seen in pic two and three there is a hole. I was able to shove an exploratory stick way up, so there is clearly space there. There are two areas like this. Does anyone know what I am looking at? Do these holes allow water into the bilge? How did A-24 stay afloat before me?
The hole can be seen in the center of the purple filler and goes straight up.
Here is a closer shot.
