Mast Splice below the partners???

Have you run the numbers on the ideal moments of inertia for this boat? Again, I don't have access to the data here, but if things are the way they sound, deck-stepping the new mast could be disastrous.
Fair leads,

Thanks for the great info Brion!

So what I'm taking away here is... that say two identical profiles, one keel and one deck stepped, the keel stepped rig will be 40%ish stiffer just by configuration?

In the latest iteration of possible take-off rigs, I've found the same exact profile except 11 ft shorter, going from a triple aft to double aft... Butt splicing this 7 ft brings the kicker and goose in the right height, and leaves the splice just below the deck...

Impossible idea?

I have not run moment numbers, only going by what was on the boat prior. Dubois and Wauquiez have been completely unresponsive for the better part of 3 years of attempts for all other inquiries as well as this... Any recommended reading???

Thanks Again!
