Second year of use of my cedar strip canoe. Had some bubbling with water ending up trapped under outer layer. I think it was just under the varnish. In the picture you can see where I have peeled some of the varnish off. It looks to me like the fibreglass is still bonded to the wood. So not delaminated? But you can see there is discolouration of the hull in the area. Any idea what happened here and what could be done to deal with it?
Delamination issue?

I can't tell for sure, but it looks to me like that area in the upper left is missing the fiberglass. The weave pattern is left in the resin where the glass used to be and the white-ish edges of that large round spot are fractured fiberglass, from which the missing part was torn away. If you could physically "peel" something clear off, it wasn't varnish, it was fiberglass. The typical thickness of the fiberglass layer on a stripper is only about as thick as a business card. The darkened wood is the result of water getting in, which is pretty much impossible to fix from a cosmetic standpoint on a clear-finished stripper. Though the wood can be allowed to dry out, the old fiberglass feathered out and new fiberglass applied as a patch where it was missing, the staining will likely be permanent.
