Prout construction methods, moisture in fibreglass and Prout Quasar experience reques

Looking for some advice on Prout Quasar hull construction and if anyone is familiar with moisture problems in or throughout the fibreglass laminates. Surveyor recently detected high moisture readings on a Trammex testing tool (testing gel coat, not bottom paint ). Sounding with a hammer produced results from “very thin sounding” acoustic readings to OK sounding but also included some delaminated type responses too.
He was perplexed because there is no evidence of any wood core below the Deck to Hull seam
We took off lining panel internally, opposite stbd head, to confirm no core, and found high readings internally too on a towel dried and clean surface.
So he mentioned a potential for delaminating laminate from laminate in the pure GRP hull construction
Has anyone had a “no side effect” experience of a soggy Prout? I’m concerned about structural strength and integrity
Late 70s construction - with some small blisters too, but ones I can monitor and deal with. No blisters in the high reading areas outside “yet”

I know of a couple of products that had rebuild the heels and parts of the hulls due to the water in their tanks causing issues.

Thanks for al the pointers - made for some interesting reading and also the first time I’ve seen someone having many criticisms of Prout build approach/quality
Have always seen people calling them slow but safe, overbuilt tanks of the sea
Seems like there are some models that struggled in the early days

I’ve also seen posts of keel water tanks flaming into water flow and ending filters
Saw someone rebuild a keel too, but I think they popped a hole during beaching

I wonder if 40 years of water storage would see fluid wick up through the GRP
