For the attachment to the keel eye, I use a Schaefer Double Jaw Toggle. The line runs around the pin and I use a stainless bolt and nut at the bottom of the toggle to go through the bottom of the toggle and the keel eye. I believe it is WM part 285736 3/8 inch. You have to rotate the keel eye 90 degrees to fit into the toggle. I tried a pulley on this, but the smooth stainless pin works just fine by itself.
Make sure you are not using Sta-Set X to lift the keel. I had a line break on me once. You really cannot see the condition of the inner braid with the cover. Also a low stretch parallel core line does not make sense for this application. I use Amsteel now.
