@viennawriter Yes it is mend able, but I certainly will have to put more effort in it than anticipated to do it right. There are a few more cracks in the Hull already.
I am still not entirely sure what the best solution might be, single patches, using some PVC Paint or just welding a 700 gram hull over the existing one.
@zem It's a boat, right? So probably it will get the next cracks when sliding over sharp rocks in the water. I have no experience with boats, but would probably do both, mend the first layer with patches and put a second layer on top? But I'll be happy to learn, what is actually the best idea for that purpose.
