Use Clam Cleats
I took off the old cleats and filled one of the two holes. To fill the old holes, I used epoxy to fill the hole within 1/16" of the top and then used gel coat patch for the last. The holes are virtually invisible.I bought two new clam cleats and drilled one new hole for it. I now have two effective cleats instead of the old "bollard" cleats. They are much easier to adjust and use for trimming.I also took the winch off the mast and relocated it to use it for the halyards which are now led aft to the cockpit. It works great and I can adjust halyard tension from the cockpit, now.
