Creaking sound and feel

[Solarken]

Hello,

I’ve noted over the years a kind of creak or pop sound on the starboard side of the cockpit at the cabin bulkhead. Never thought much of it at sea in waves. Never felt it much at anchor till now. Conditions are less than optimal. 45° swell rocks the boat. Mostly gentle. But we know those power boaters that drive by at 15 knots making a 3’ wake! Well, as I was holding on from one of those assaults. I feel this pop at the companion way on the starboard side. Always though wood on fiberglass rubbing. But it feels more like fiberglass to fiberglass.
Any thoughts on this? Anyone with similar occurrences?
Thank You!

The 38 does that. Cockpit well moves against ply bulkhead in starboard lazarette. Not issue but does gets squeaky to windward in a seaway.

I just figured out it’s that bulkhead rubbing in the inner part of the hull. Where the electrical panels are. You can feel it happening if you get your fingers in that space. Small pop but big noise!
