E32-3 - Bulkhead seam?

Hi all,

After a high-wind race this weekend I took survey of what I may or may not have broken, and I can't help but feel like I didn't notice this slight discoloration / seam in the primary bulkhead before. This is on the port side, near the interior hull planks/headliner in the saloon. On the other side is the head.

Is this just a construction artifact or is it possible some hull flexing / crashing through waves is working something apart?

Seems to me that if it was due to flexing there would be an obvious crack top to bottom. I wouldn’t worry about it, but would keep an eye on it to see if it changes at all.

The surface veneer has seams where the surface wood sheets are butted, and with moisture (humidity) and drying, a crack will sometimes be visible. I have seen this in other types of cabinets.
what does the opposite side of the panel look like?
