Sorry for the late reply, I saw it only now. It looks like delamination of the hull. Likely as a result of running aground (*). The delaminated material was removed and filled with some filler - it restores the hull shape, but not the construction strength. As other people wrote, there is a risk that if you run aground next time, the filled area cracks and you get a massive leak you will not be able to deal with.
The proper way of fixing it is removing the filler, evaluating the damage, and re-laminating it using good technology and materials.
* Often, running aground at speed creates visible damage in front of the keel. Here it seems, that the damage is only behind the keel. However, the options are:
- the damage is there, you just haven't noticed it yet
- my understanding of the FE83 hull is that the rear wider part is weaker (less strength and less stiffness) than the front part - maybe, there is damage only where you saw it
- the FE83 keel has the "traditional" gap between the hull and the iron keel in the front part, all the energy of the collision was absorbed by that part - maybe, you have a lot of Sikalfex there.
It is worth re-checking the keel bolts. May the floating force be with you.
