I found several small cracks in the gel coat in the transom area on mine, but the cracks did not extend into the substrate. Making a v cut with a pointed burr, it was easy to see that the crack was just the outside gel. Some epoxy fairing, sanding, and back to good. That turn from the hull to the transom is the thickest part of the entire boat, not thick enough to grind out the hook though. The hook can be measured on the inside, just not as dramatic as the bottom. Transom looks great, but now I'm worried my full width piece will hit the top.
