Hairline gelcoat cracks, common?

I got one on the corner of my transom. There is no gap, its barely visible and doesnt how up even in good lighting on my camera.

Transom isnt over weighted. Boat is 6 years old.

I cant see any water getting through it as it looks so faint, but isnt there a layer of glass before the wood anyway?

Pretty common. Most hull materials are not completely rigid, and gel coat doesn't play nice with flex. Assuming it's not spreading, hitting it with wax (car wax should do) will help keep water from getting through. Spider cracks, they're usually called. A web search should give you more info.

how much figlass is usually under the transom before the wood?

there are no other cracks and when i tap the transom its solid as. is there a better diagnostic without drilling the transom?

almost ever small glass rib ive seen has these hairline cracks where the false floor joins the transom.

its kind of more on the seat than the transom.like where the glass slopes away to the hollow seat posts that the bench sits on. i dont think the glass can be very thick as it sounds much more hollow than the deck or the hull.
