Just to clarify in my mind…The boat is a ‘92 with a fiberglass board, not cast iron?

The board doesn't appear to be glassed but the trunk appears to have added material at the bottom around the slot opening that reduced the clearance with the board to zero.. Original construction or later repair - unknown. It's plain to see by holding a straightedge vertically in the slot.
I sanded the material down enough to allow free board movement with 2 coats of bottom paint. I'll know tomorrow when the board is reinstalled if I'm successful. The board and trunk will not have any barrier coat since I removed it when the jammed board was discovered. A lot more material would need to be ground from the trunk to allow clearance for barrier coat.
When I first launched the boat after purchase, I noticed a slight bind when lowering the board. I thought at the time that the pennant was binding somewhere when in fact, even without bottom paint, there was interference between the trunk and centerboard.
I'd be very interested to hear Jerry's opinion.

Did someone glass the board?

With all the barrier coat and bottom paint removed, holding a straight edge vertically inside the trunk, the opening *at the bottom* is uniformly ~0.020" narrower per side (0.040"+ total) for both sides. The board jams at the very bottom of the slot when raising or lowering.
Is that how the boat was built?
Maybe to minimize flopping of the centerboard when lowered?
This area of the trunk needs to be sanded away to make clearance for bottom paint. Never mind a barrier coat.
