Pedro, the Laser Foiling Guy, is in Bermuda and called with an update as we watched Team NZ lift its rig for a practice sail.
Pedro shared an interesting rumor. The huge wing is articulated so that the angle of attack can be controlled for the lower, middle, and top third. Just like flattening the top of a Laser sail, the AC trimmer can control the twist when overpowered. Nothing new here.
But the rumor is that on some boats, the top can be be twisted further to create a negative twist to push the rig to windward when really overpowered. Interesting!
