The above is very true. And pics may help as others have suggested. It would also help to have some Non-Destructive Inspection
done. Say via a thermal imager. http://www.cruisersforum.com/forums/...ys-175180.html
That way you might be able to "see" what's going on inside of the keel's fiberglass shell. As besides that, it would seem that the only way to really know what the issue is, is to open up said shell.
Out of curiosity, is your boat
one that's spent a lot of time in salt water
? And either way, has the (galvanized steel) beam been inspected, & or replaced? It's under the compression
post, encased in the fiberglass floors structure. So that were it corroded prior to the impact, it may have broken free of it's mountings. And or, crumpled from the grounding's shock.
Here's a page which documents one owner's replacement of his beam. And the rust issue is a major one on Cal 40s that's gotten a fair bit of press.

Edit: How do you know that there's movement in the keel? It's encapsulated, which would seemingly make knowing this a tough thing to determine, non?
And in order to get a better look at things, you may need to purchase
a bore scope
. Along with drilling a few holes discretely into the floor pan, as well as in the casing which surrounds the described beam, above. They're pretty inexpensive nowadays. And they even have them at Harbor Freight, though I've no idea of the quality of said units.
BTW, if she's on the hard
, it's likely wise to use more jackstands than usual to support her. With more of her weight on them rather than on the keel. That way hopefully you'll put less stress on the internal glass work
that's still in place above the keel. Ditto on her keel floors.
One other early morning thought is to try posing this question on some of the Cal owner's groups. Such as the one on Yahoo for example. And if you do, please let us know what you find out
