I fortunately stopped short of removing the glassed in keel bolts of our previous boats.
After all other sources had been ruled out (I thought) it was the next horrible step to take - until someone pointed out the rudder possibility.
The water had taken all possible little paths from the (slightly raised) stern to the other wise dry bilge; and to make matters worce, some of the interior held back some water and released in untypical conditions.
After fixing and tightening some bolts for the rudder, the boat was dry again...
All symptoms had been precisely like you describe yours.
(currrently we have slight issue with a spilling colling water tube - but thats mild;
and fixed a "designed" calorifier valve leak with some tubing to the stern)
I also do not think it is from the keel bolts. You would most likely have a regular seep with tell tale rust staining on the GRP around the leaking bolts.
Are you sure it in't a leak from the hull/deck join or toe rail fittings when the boat is heeling?
I've got something similar on my new (used) boat and I've been suspecting a leak around the bolts, although there seems to be much scepticism here I've been able to rule out many of the other sources suggested. Has anybody ever tried tightening keel bolts in situ whilst the boat is in the water?

If your keel bolts are leaking I doubt tightening would hve much impact. You will probably need to bring the boat out and reseat and seal the bond.
