they may be really springy, when sat on they could flatten out ?????

Another thought, are they curved so you don't just slide off them when the boat is sailing nearer to upright?

As long as the wing to wing measurement is no more than 2250mm they are legal, the more they angle upwards (the curve may be ergonomic but makes no difference to max leverage) the longer that can be (from hull to tip) without exceeding the max width measurement. Leverage increases until the windward wing is horizontal. That is compounded by the fact that the roll centre of the boat is a couple of feet below the hull when foiling so the righting actual moment is the horizontal distance between the RC and the end of the wing.
And, yes, it does look very jewell

Nope I still make the argument that if you follow the logic,
1) They are closer to the centre line. 2)They permit the rig to be hauled further to windward without dipping in the water thus reducing the sail area presented to side forces and generating more upward lift vector without over cooking the righting moment and going in to weather. That means less righting moment, but more versatility with the righting moment available. I reckon. Or.. sudden thought they are actually wider, but being curved upward remain within whatever measurement defines how wide they can be, then they do all that stuff I said up there anyway. But they certainly look kewell and I hope it blasts to the front of the fleet. Edited by iGRF - 05 Mar 17 at 11:52am |

Presumably the wings will be max width (no point in them being narrower) so being upswept must increase the righting moment as the boat heels to windward to the point when the wing is horizontal?

I'd love to think it is simply to make the boat looks cool, like something batman would sail, but pretty sure it has been well thought through for max righting moment.

The moths sail upwind heeled well to windward so those canted wings then effectively become horizontal and increase the leverage

Think I might have met him later if he's the lone Burfield warrior.

I dunno, the wings being as high as they are, were in fact closer to the centre line, that was quite obvious from another Moth nearby with conventional straight wings that only raised the 'normal' angle. So not 'more' righting moment than normal in fact you could argue less, maybe a heavier sailor who wants to ride more inboard and lever from there, my money is still on more windward cant and therefore more lift from the sail to complement the foil, it would have been great if someone had been on hand to ask. Ironically I met a guy who allegedly had a hand in it, old mate from windsurfing, Simon Reynolds a mothy, I should have asked him he'd have known.
