Hi Andrew,
Why aincha going to 31' mast while you at gettin' a new sail? Not that hard to add the foot to the head of the mast, and mine and Jay's are working out well. Fact, we prolly got some extra extrusion.
And, like the guy said, why 10' beam?

The mast is a Marstrom Tornado tapered extrusion, probably 1970s vintage, and measures right at 32'; the finished luff of the sail will be 30'.
Why 10'? I have the beams, and at just over 1/8 of a ton (260 lbs) dry weight, I've NEVER "needed" to trap upwind on my 11' Square. The 10' boat will lift a hull sooner, yet the squaretop will allow depowering (if/when it's needed). The drop lever traveler remains a viable option, tho the pics I've seen show it with a beam-mounted boom which angles up sharply. My boom is intended to be nearly horizontal, so I don't know how well it would work. More thoughts tomorrow, thanks y'all.
