Seeing as I didn't seem to remember the exact number of keel bolts (advanced old age), I went down today and counted. There is one ahead of the mast, two just aft of the mast, four under the dinette settee. three under the galley sink, and one under a hatch just aft of the galley. They ate all 1" except the last one which is 3/4" All are fully accessible and the full length of the keel base can be inspected. That's eleven total. All are 1" except the one behind the galley. It is 3/4".
I took pics with my I phone but I am still new to using it so I will have to try to get them to email if you would like to view them.
