Lifted our 22 O'Day earlier today to apply a new pendant with shakle to the centerboard swing keel. Previous pendant line is applied through a 3/8" hole in the lower "edge" of the keel and through to a lateral hole 1.25" where a knot was applied to retain the line. The 1.25" hole, with the knot was then encased with an epoxy type product and the sides smoothed. Question: Is this a normal or original type application for our 1979 O'Day?
