<<I have noticed that my starboard bulkhead which forms the aft wall of the stand up locker has pulled away about 1/2". >>

The head is opposite this locker so you have two issues: the starboard bulkhead pulling away from its tabbing, and the head door which is framed by a support arch that is your mast compression system no longer closing. And this happened after you center punched a fixed pier? Do you suppose these things are related?

<<I probably should have been clear on the fact that the glass tabbing itself is in order. It is only the wood dressing that has slipped away, about half an inch. But this is not a structural component, which is probably why I was told to leave it alone and just shave the door.>>

There is no "wood dressing" as you put it on a first gen Bristol. The bulkheads are plywood. The plywood is tabbed to the hull as is all of the furniture in the boat, and why the boat is so strong and rigid. If the wood has pulled away from the tabbing you have essentially broken your bulkhead at this point. Squeezing 5200 into the gap will do less than nothing--only make a godawful mess to clean up before you can do the repairs.

The fact that your head door will not close means that the mast compression system is somehow compromised and is not supporting your mast correctly. It might be related to the collision or it make be simply that you are suffering a failure of the maststeps at bottom of the two vertical frames for the head door--something other B32's have suffered from--or a failure of the horizontal support above the head door that connects the compression of the mast to the two door frames. Tightening your rigging will not solve this issue--it will only drive the mast down more, and cause further damage.

The fact that you hearing creaking and noise when the boat is sailed hard is a big red flag.
