Is this a 30 MK1? If yes, on this boat the chain plate is attached to the "knee" and the knee is heavily glassed to the hull. What you see on the bottom is just a shelf which goes around the knee and doesn't provide any significant structural support. The knee continues though the shelf and ends few inches under. You can't see this on the port side due to the wood paneling (I have built a removable door on mine so I can inspect it) but you should be able to see it on the starboard side if you remove the cushions. When the knee starts to separate from the hull, it usually starts from the bottom where glasses mats overlap which you should be able to see...

Not sure if this is structural or cosmetic. Had someone jump up and down on the portside deck forward and aft of the shrouds to see if there was any movement. Didn’t see any.
