Wouter, et. al.,

If the hulls are of equal weight, unlike a proa, then if you put the mast on the leeward hull, you have the righting moment of nearly the whole boat's weight, but inversely, if it's on the windward hull, a much smaller righting moment, but a much larger displacement moment of the leeward hull.

I've always had a novel (I think) solution as well, but don't want to post it here. (the idea).

If you or another builer type could e-mail me, there could possibly be a patent in it.
