All the C&C Keels have a safety factor of FIVE with the boat heeled 90 degrees . . . . so that keel joint is pretty conservative.
Cracks and ‘Smiles’ are normally the fiberglass bending (it is plastic remember) outboard of the bolts and washers . . . The best thing to do (although we never did it) would be to have the ‘washers’ the full width of the sump – to hold that corner down to the keel top. You can’t get all the way, of course, but the farther (closer) to the actual outboard corner, the better . . .

Our keel weighs 7000 lbs but with the nuts off, hanging on it own weight on just the bolts it didn't move at all. Wedges were needed to break it loose and then a couple of very short hydraulic jacks slipped into the gap to push the keel the rest of the way off past the keel bolts. They tell me there was about 10,000 lbs. of pressure on the jacks to push the keel bolts and keel down and off. That thing was not going to fall off on its own. ...and on examination the keel bolts were perfect, not the slightest sign of crevice corrosion or any other issues.
