@zem You intended it what for?
@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.
@viennawriter Actually it seems that in this case the folding of the skin is the problem not rocks. I will work on that as well, there is a trick where the hull is not bended that hard. 🤔
But you are right those boats have to be driven with a hand width of water below the keel.👍
