Thanks for the reply! I guess I should explain that I am a complete newby as I have no idea what calculations you are referencing. Can you point me in a direction to look?
I am a mechanical engineer but haven't seen column buckling problems since college 30 years ago! And those were mainly static structural loads. Willing to learn it again but not sure what to look for. Please note that the old mast broke on the previous owner when the back stay snapped in high winds. The mast lasted 30 years so I would guess if I matched its rigging set up it would work again. But I'd rather not have to put more holes in it if it isn't necessary.
Thanks!
Paul
