yeah this kind of problem that I was wondering. also if the relations hull/ grid is so fragile, what will happens if you stress it even with a small touch of the keel
wich is so common, in our 11 years out sailing around we had a record
of usually touching ground once a year, when up the rivers, or entering very shallow bar in the rivers, or navigating in coral
waters that for some reason were a little murky or just bad navigation
like one day at the bay islands of Honduras
. Always light and no more than some scraps on the bottom of the keel
... but with this kind of boat, this can be a problem...
