destructive testing submarine yacht

This ferro cement is really nice to work
with, I'm thinking of later making a big boat using ferro cement with ferro
reenforcing rings at close intervals. I would like to then test to
destruction but here in California they would make me go down and pick up
the pieces and then take to a landfill and bury everything. Other option
would be to take to a Navy pressure chamber and test but that would cost
$$$.
