Luna Rossa Challenge. AC 36

It's official Prada cup practice, they are allowed to race one another.

Obsolete now, but my comment was last week. Before the practice days. Cheers.

During the presser today Max suggested the backstays ruling is still under discussion. That made me remember a comment posted by someone (happens to be a 35-yr commercial airline pilot) during TE’s latest webcast, where he made a possibly off-the wall comment on the subject..

Could LR, in burying the stays inside the rig, be going after a ‘gurney’ type wing control feature?

Does @weta27 or one of the other superb NZ photogs have detailed shots of the mast head on any teams boat with the runners attached? Or even better of LR with or without the runners connected at deck level.

While I understand "every little bit helps" I just think this whole backstay thing is a bit of a show. Similar to the jumperless rigs in the IACC v5 boats in Valencia. BMW Oracle had dummy jumpers during the lead up, but shed them once it counted- ultimately the team had tried to be too tricky with their equipment, and the gear wasn't reliable and didn't pay off. And with LLPR we have seen early engineering fail in the form of the foil arms, bow, and I'm sure lots more we will never hear about. I hope they keep their eyes on the prize and not get caught up in being too fancy...

Doubt it. A Gurney flap (with capital G after F1 and Indy racer Dan) assumes one could place precisely a 1-2% orthogonal strip on the leech, windward side. But mainly, its effect would be yes a significant increase in profile lift, but at the expense of an even more significant increase in drag

As always, the Italian team looks the business. Looking forward to the racing this afternoon.

Have we seen any photo or video evidence of this 'offset' grinding set-up LR are supposed to have. Fucked if I can find the reference anymore but I'm sure there was talk of the LR grinders having an assymetrical/offset handle position to improve efficiency....

Luna Rossa's crew work, like their boat, looks fantastic, but will it be fast?

Helm and flight controllers, two most important roles, have half the real l world experience, will this count against them?

I shorten sticks down to min for drone racing too..and obviously they learned the pinch method of manipulation.

Apologies if I’ve missed it with the abundance of other news, but has a final ruling been issued on the removed runners?

Yes, here the links. No good news for LR. They must race with the backstays on, and they can't hide them inside the double mainsail.

Cool video.

Fun to watch the onboards. It was almost as interesting as the main feed today. 

The bottom mark rounding followed by a tack is what they call JK, but what does it stand for?

Jon Kosteki, he called those bottom gate tacks to JS on the OR AC72 in big SF breezes.

JK was clearly ahead of his time with the JK . Back then it was radical, now it's de rigeur. INEOS pulled it off cleanly a couple of times yesterday.

Korrekt! These AC75’s are nailing it, very impressive.
