Being able to cant the rig radically to windward is essential- a shorter fall for me as I tip it in (yet again)

the rig canted to windward gives more righting moment too - and I believe this aspect is considered to be highly beneficial - but I may be out of touch

It's not the rig being angled to windward but the fact that the boat, when foiling, pivots around the bottom of the foils (the roll centre?) so leaning to windward moves the CoG of the boat plus helm further to windward of the 'roll centre', the righting moment works vertically downward (gravity) so the more you heel the greater righting moment you have. The opposite applies too as anybody who has allowed a Laser to heel too far and the point of no return comes when the sailor is above the centre of buoyancy (which in the case of displacement sailing is effectively the equivalent of the roll centre?)
