I have a 19' Oday made in 1980. Last summer I developed a leak that I think is in the fiberglass surrounding the keel. My problem is I cannot find how to remove the swing keel and fix the leak. The boat leaks especially on a port tack. Has anyone ever worked on this part of the boat? It seems like there should be an easy way to access the area but I cannot find it. The picture attached is only to show my boat to see if anyone has one like it or knows how to work on one like it.
