Hi, I just bought a 1980 s 37. When on the hard it was quite apparent that the resin compound between the keel and the hull had become loose thereby leaving some wide cracks. I've disvovered some info into how seidelmann attached the keel but what I'm lacking here is how to detach the keel. I noticed that the keel is actually recessed into the hull and I'm wondering how the he'll I'm supposed to fit a saw blade in there. Has anyone ever dropped the keel on a 37?
