Robert hit it on the head with this. The PSC masts are built like a telephone pole. You'd have to put a considerable amount of over tension on the rigging to get any real amount of bend in it.
Do you have the LeFiell mast, or did PSC change the vendor in more recent models?tml[/url]
I believe that it is still LaFiell mast, not 100% though, I'll know about 0930 tomorrow. I actually tried to do a quick calculation based on LaFiell's information in the link you sent, but they didn't give the units on the moment of inertia, so I'm not quite sure if its coming out right. I've got some mast section data at work that I'll check tomorrow and see if I can't figure out how much tension would be required for a couple inches of rake.
At any rate, the one I believe the boat is fitted with is the OM3D, very beefy as you note. Definitely not a floppy racing rig!
