No, not realy
Like the others have said. Only if it is really bad will the wear be obvoius in the water as told by the clunking sound. That is the noise of the keel hitting the sides of the keel trunk.Many people do not understand the Catalina keel pin design at first. It is unlike most others in that it is completely self-conainted on the underside of the hull. Nothing comes through the hull, so nothing is visible while the boat sits in the water.Best thing is to pull it out and get a close look.Regards,Ted
