Josh,
If Chris rebuilt the mast step, he must have unstepped the
mast......don't know how one could rebuild it without the mast out.

Chris,
The prevailing wisdom of this list suggests that the keel bolts only
be torqued while the boat is resting on its keel, generally about 60%
of it's weight depending on the design. In this way you are not
turning the nuts against the weight of the keel or even trying to
compress the bedding material. IMO, it is likely that you will find
more movement in the nuts when you retorque on dry land.
I am not familiar with the design of your particular boat but some
boats have keel bolts which are entirely inaccessible with the mast in
place. Make sure there isn't one (or two) hiding somewhere.

Status update: I ended up torquing the keel bolts. They were not
incredibly loose but all of them needed tightening, two by a turn
or more and the other two by less than a turn. I will know if this
removed the keel movement when the boat is next hauled out,
although I am also thinking of diving on her to see if I can
detect any wiggle that way (I live in BC and the water is pretty
cold but manageable for a few minutes with a wet suit - I hope!).
I believe that a very small looseness in a narrow keel root would
result in a fairly noticeable movement at the tip of a 3 foot keel
- even 1/8 inch of movement over 2 inches width would translate
into a couple of inches at the tip, if I have that right. So
hopefully this was the issue!
I took Drifter for a sail today after rebuilding the mast step and
did not notice any flexing or movement in the floors or hull (made
pencil marks on the floors and adjacent hull skin and checked on
different tacks). I also checked the tabbing under the settees on
one side and found it intact, so suspect that the surveyor may
have jumped to conclusions when he said the hull had been
compromised and that was what was causing the keel movement.
Thanks again to everyone for their suggestions.
Chris
