I found it interesting that the webs in the keel stub were cored apparently with foam. Stiffening for the keel stub is not a place that I would use foam coring. I would like to have seen a substantial solid glass grid that spanned the top of the stub by about 4 feet on either side and was glassed all the way down to the bottom of the stub with about 2" or thicker solid glass webs through which the keel bolts passed. Also the part of the hull the grid was bonded to should have been solid glass. Just my opinion.
