Dave,
rather than plan for graceful mast failure we can design for no failure.
Designing these things is not difficult and beats worrying everytime a heavy
wind
comes up. I had a rather flimsy wooden mast and it would keep me up during
wind storms. I built is light so that if (when) it came down it wouldn't damage
the house. But with metal masts I have the numbers to calculate things and can
sleep better. 73.
