I know I am in way over my head here, but I have questions, and I can't help it.

Grob says:
I didn't misinterpret righting moment and healing moment I deliberately swapped one for the other. My understanding of these two is that while they have different meanings they are equal and opposite so one can't increase while the other stays the same.
Can you explain how RM and HM can be different.

And Andrew says:
Righting Moment (RM) is the force that tends to keep the boat upright. Heeling Moment (HM) is the force that tends to knock the boat over. Shifting the rig to weather will increase RM the same way shifting crew to weather does: The lever arm for the mass of the rig is increased. HM stays the same, because a rig of X height, having a center of effort Y feet above the deck, will ALWAYS have the same HM. Of course, as the weather hull flies, the HM increases faster than it does when the rig is centrally located, as it rises above the water (and the leeward hull) faster.

And Mary (that's me) cannot understand physics concepts unless she carries them to their ridiculous extremes. So she interprets Andrew as saying that it doesn't matter whether the mast is on the leeward hull, in the middle of the boat or on the windward hull -- that the heeling moment will remain the same (except that heeling moment will increase faster if the mast is more to the windward side of the boat.

Did I understand Andrew correctly -- and is he correct? If so, it challenges my limited store of common sense.
