I have an ODay 22 with a fixed keel. The hull has no holes except the discharge port for the galley sink. It takes on water at about a gal a day. Unfortunately, it was unattended for about two weeks and (I presume) it went down when the water reached the sink drain. I have looked closely at the hull, esp. around the keel and depthfinder but see nothing wrong.
Any suggestions?
