Thank you, Dennis, for the thorough explanation. I had come across the "C&C smile" in the list. My first instinct was that it's related. When I see the close-up photos of your 35-1, I can recognize it's the same kind of crack (same general width and depth).
However, the cracks have different shapes. The cracks of your 35-1 are only present at the front of the keel, and they are at an angle, actually resembling a smile. The cracks on the 38-3 I visited are perfectly horizontal and extend all along the keel. Does your 35-1 have a deep bilge, like the 38-3 I visited? If it doesn't, that would explain the difference. As for the washers, they are present under the bolt nuts. Visually, they do not seem degraded to me. But I'm not confident that a problem is always visually detectable. One of the items in the album I linked originally is a video. The camera gets quite close to the bolts.
