This is the general problem with all hydrofoils...
Even if it was produced well and in one single mould (in one piece), a grounding CAN break the foil, especially with higher AR wings of course, and particulary if tilted, the force/torque can be extreme.
Then one can discuss whether we want to have "weak" points, or better to have it break totally "somewhere not very defined".
I dont know the best solution and very individual, but of course it is a common issue, on ALL hydrofoils, and the more performing the worse it generally is
