I think it’s something to do with a bow up sailing mode that they keep using. If you were trying to initiate a very high mode and see at what point, the flow detaches from the top surface of the foil you could use a test like this

Yeah, it does remind me of flow-vis paint - an underwater version, perhaps.

Possibly where on the foil it detaches rather than at what point

Keep applying it and at the point it stays there you know know isn’t or you can see it breaking up
as a team they have done alot of the bow up mode testing and always hard upwind, personally I think they are looking for a really hard up wind/high mode after getting done in the start box by LR who had the best high mode of all the teams
blending a high mode into a foil that’s raceable with a low stall speed yet fast enough. I think it’s where they’re heading

Its interesting listening to the commentary from the teams who designed their own LEQ12 and lined it up against the AC40 (LR and Ineos). The common theme was that the AC40 is lighter than the LEQ12. Given that the Version 3 AC75 will be a lot lighter than the version 2 AC75's, it may be interesting to see how those teams (LR and INOES) have scaled their LEQ12's. Whether they're scaled down from the previous AC75 class rule, or whether they're scaled from the the future AC75 class rule. If they've scaled down from the previous AC75 rule, and the AC40 is scaled down from the future AC75 rule, how that decision affects the data collection and how that data scales up to the new AC75.
When they started training on Te Rehutai again recently, ETNZ noticed the weight difference of Te Rehutai in her new configuration, being lighter, brought about new performance characteristics. Wonder if the AC40/ LEQ12 has given ETNZ the ability to scale those characteristics up more efficiently than the other teams.

Luna Rossa and ineos will surely have scaled their leq12s down from the model that their testing results have returned to, the v375, currently under build for most teams I think.
Alinghi and American Magic are in the same boat as us, so to speak, training in a v275 against a 40/leq12 combo with results again being driven towards the v3.
A prior point raised and a good one was which was the best way to go.
I feel the tboat path could yield the best results for the v3.
That said, I'm naturally conservative and more than happy with the Etnz way.

Bit more obvious what is rubbing away with the blue in that video. But so much is rubbed away I'm not sure what it is telling them. Anyone?

That the flow is detaching 2/3rd back from the leading edge
which on its own doesn’t tell anybody anything what you need to know is precisely what angle everything was set up, flap,arm, heel, angle to the wind and any other hundreds of variables

I get that but because those will vary during the sailing I can't see how it would help
Though I guess with cameras they can tell when it comes off

The third session began with a self take-off before the team repeated the exercise of 'painting' the outer upper surface of the starboard foil wing that they did on their previous outing last Friday.
This time the 'paint' was a much darker colour – presumably easier for the foil cameras to spot.
It was applied by a fifth crew member on board just for this exercise. As during the previous session the foil would be painted, the crew would sail for a few hundred metres on starboard, then tack, sail bow up on port, and then stop to photograph the foil and reapply the paint.
This was repeated three times over a half and hour period.
Cup Spy - June 13: The teams continue to wind down ahead of the shift to Barcelona
Two teams sailed - both in the Med. But Barcelona beckons as the Brits start winding down their program ahead of shifting to their new base in the host city for the 2024 America's Cup. The Kiwis AC75 is about three days out of Panama.

it sounds like they are following a set test pattern or something crazy like that?

Presumably with small variations in something. Though on the runs we could see I couldn't see much difference in the paint. Though they were photographing it so maybe in analysis they can pick up something important

I think what it actually illustrates, is that teams have a better idea of their testing schedule, methodology and regimen than the inhabitants of sailing anarchy.
the bow up trim has been a long standing feature of thier program on all three of the foils they have trialed so clearly they see merit in it as a test criteria to get them the performance they want.
