    looks like they are trying to get some end plate effect on the second image. I have wondered why no one has tried that on the mail sail as well. it would effectively increase the aspect ratio and likely would be a rule "cheater" that limits sail size.

    It has been tried(well, winglets anyway) to, apparently no great advantage. Lumix, the aydeen above has won at least one race with that rig and also is using the first wingmast in the class.

    It's also a rotating mast. I'm assuming that the headstay is still straight from deck to mast and they aren't using that batwing thing to deflect it. If so it appears that they headstay hits the mast considerable higher then the boat it's sailing with. This would give them more separation for a given luff length, looks like the luff is shorten than the other boat which would give allow them the chord length.
