      Why not have the mast straight, and just angle the sail away from
      it? Would the difference in lift be that big a deal?

      Could be. When the low pressure side is up, a force is created that
      resists heel. When down, it would increase the heeling moment. Of
      course, if the sail were far enough over to the side of the boat, it
      could matter less.

      Which makes me think. If you had a trimaran with the mast stayed out
      to the amas, then if you rig a small sail on the bottom portion of
      the windward stay so the vector of force created went down between
      the ama and the main hull, it would create a righting force as well
      as a driving force....
