What do to with my damaged gelcoat hull

[canaryo]

After removing the old paint layers down to the gelcoat on my 7m fiberglass boat, we discovered a lot of damages, scattered across the full length of the submerged part of the hull.



There were no bubbles or blisters and no smell, however on 4-5 small spots, a very sticky substance is leaking out now (where the fiberglass is exposed).











The plan now was to sand down the spots with broken gelcoat a bit further, wash the boat regularly, and to fill them up with epoxy after the boat has dried (located on the Canary Islands).


The fiberglass itself is too thin to peel the hull, as this was a mass produced boat from the early 2000s (only around 8mm of wall thickness).


My main concern now is that the boat will not dry properly for the repair with the Gelcoat on within a few weeks - I think the hull has had some time to soak.


We took some measurements with a Tramex but as the inside of the false bilge was still a bit moist the results might be off. It was all around 25 on the submerged hull side.


Is this a stupid project or does the boat still have potential?
