Righting moment is what gets you foiling in the first place(pops you up). The end game is foiling at minimum class limits, so yeah it's important at least in the direction I've been studying.Not to say some other innovation won't negate that altogether, like a center Moth foil, but active controls are still illegal.
You would still have the same righting moment in sea-hugger / displacement mode to initially get up to speed and would have the righting moment reduce as the boat comes up on foils if the foils were inset. Heck, it might be an advantage in some situations. It does seem, however, that the current method of foiling on the a-cats requires the trapeze action downwind...but that need might change as the speeds and apparent wind increase as the foils get better. I'm just tossing out ideas. Regardless, it will be interesting to watch how it develops.
