The new piece was added across the width of the boat and at least 4 feet away from both compasses
Compasses don't agree

it is metal but its certainly not one of those cowboy dinner plate sized versions. Bare minimum metal design
So I did some more digging into the issue and with a handheld compass at the dock I find that the starboard compass is only maybe 1-2 degrees off from the handheld. The port side compass is 30 degrees off. I tried adjusting the small tuning screws and improved it but the best I can do is get it about 15 degrees or so from the reading on the starboard side. I'm out of adjustment. Does anyone have any ideas on what I should try next?
Can you take the compass from the port side and carry it to someplace else? It might have wires for its light that would need to be re-spliced, but at least that would help indicate if there’s a problem with the compass or with its surroundings.
I'll give that a try. I will try holding it near the starboard compass first to see if will match in that location, then on the dock
The magnets in the compasses might affect each other at very close distances, so don’t hold them too close. Other than that it sounds like a good plan.
I wonder what would happen if you exchange the compasses? Mark the one that is correct.
If exchanging would produce the same result, then you know that the compasses are good. If moving it to starboard and it continues to show inaccurate result, you know that the compass is at fault.
