Do you mean are there bolts visible on the sides of the keel? If so, the answer is no. There was a fish plate of iron, which wrapped around the bottom of the keel and up onto the first strake near the after end of the keel, but that is the only real feature in the area.
Ah, I see. The bolt pattern is not very regular there, since the bolts are mostly used to fasten the riders and the riders do not go so far aft. There are two lines of horizontal bolts for quarter knees in this area, as well as a few others. The drawing below shows the starboard side in this area with the bolts shown as red circles - aren't you glad we spent a month measuring in both ends of about 5,500 bolts!
