I recently purchased a 1973 Sunfish in need of repairs. The mast has abraded the bottom of the mast step well to the point where (2) dime-sized holes have been punctured on either side of the keelson. My thought is to place the boat rightside up, level it, tape the holes on the outside (so the resin does not pour thru), and merely pour resin into the well to a level that covers the holes. Comments? Yes, I have purchased a bottom cap for the mast!!! Thax. Paul
