OK, so the amas move fore and aft about a center axis? That's interesting. I suppose they pivot on both beams so they remain aligned with the center hull all the time. Neat idea....run smaller amas...leeward one goes forward when reaching and downwind to give a little more buoyancy forward and allow the skipper to get further back on the windward one. Upwind, bring them out to 90 degrees for ultimate righting leverage....this is brilliant! I would love to see more.
