you could guarantee prudent use, you might be able to better estimate

Right, not even the safest of cars (Volvo?) survive being driven off
a cliff.

Then you have the racing crowd who do things normally not regarded as
prudent...

that kind of sailing isn't regarded as particularly wild. It's a
5 tonne boat, 60'x60' on the water.

Another one: http://www.bonduelle.fr/htm/voile/fdecran/1024/01.jpg
and http://www.zedda.com/news_details.php?ID=37#
but these two does not represent severe load cases (flat water).

I have seen wilder things but don't seem to be able to locate them
again.
