Luna Rossa Challenge. AC 36

[Mozzy Sails]

Yes, and I think we saw upwind in the waves, INEOS did have good spurts of pace, but struggled to hold that groove as well. 

I do think the LR communications are pretty decent for the majority, it's just those crunch situation, the leeward helm needs to be thinking 'what additional information would I want as a helm', rather than 'what would I be doing if I was helming'. 

I might crunch through the comms on all the boats and do a bit of an analysis of who says what, about what topic and when during the race. Chart the information flow of different boats.

New chapter in the backstays war. I don’t understand what they’re planning. Maybe this last interpretation leave some room to hide them ? Seems a little less categorical on the matter

Seems that since the backstays must be fitted, someone is trying to see if they can just leave them slack or perhaps tether them out of the way. Similarly if they don't use a code zero (or whatever they're calling the sail set on the bowsprit) then they'd like to remove bobstay. I have no idea why that matters.

Just a bit more drag reduction I guess. And a little bit more weight out of the ends.

I do wonder whether we will see a C0 in a race though. Will NZ surprise us in the finals because its not looking like the challengers will

And then again yesterday when I picked up a bird's feather...

Maybe I just have OCD.  :wacko:

Bird feathers don't do 50 kn underwater. And it's a small part of a wing that fits together with its neighbours a bit like roof tiles, so it's shape isn't necessarily the same as the overall wing. B)

Interesting Mozzy.

I hadn't picked up on the chat being that of 2 helms rather than tactician and helm, but I see your point.

On the idea that LR look fast and its easy- it seems to me that they have a nice wide groove, so they found that groove early and find it consistently. Whereas UK designed a boat with a narrower groove, so it take them a while and a few adjustments to get it right, but now they have they are faster (downwind at least). So the UK boat is harder to sail, but faster when they get it spot on.

Make sense?

I think this is a good point. How I was thinking about it was LR can be fast in a wider wind range with a given sail setup. In the abandoned race, I think INEOS was similar speeds when the wind was up, but when the wind dropped a bit, LR was faster.

Yes, I wondered how it would fit in with it's neighbours. Just the first time I've seen a feather with such a profile. Curiousity getting the better of me probably.

Dunno,  before this last series it sure seemed like boats were able to foil in the light with a jib, I was pretty certain that we wouldn't see zeroes, but am far less confident now! Does explain why NZ was spending so much time on it while other teams were trying to push the jib limit down.

Indeed. Years ago, I was fortunate enough to be seated next to him at a dinner, and he is exactly as it transpires in the video, very accessible - the very opposite of BA, whose aggressiveness even on land (Trapani) was palpable

Any news in the backstays war ?

No, they’ve found out that there’s a significant VMG advantage in dispensing with mast, sails and rigging and replacing foil bulbs with electric motors/propellers hooked up to the FCS batteries. Expect a request of interpretation soon

they keep asking and getting told to fuck off, two requests went in before racing started and they go turned down

Anyone found out what the real motive was to head out without a mast? I would have thought foil testing would be better in normal config unless they are doing other mods to the mast and or boom etc and due to time limitations can do the foil testing without these?

P.S. It was said they would be fitting slightly smaller foils so this makes the most sense

ETNZ apparently went out today with no mast and tested a foil, so I assume they are Testing one foil and comparing to a current removing all other variables?

Mr Jimmy has a bit of a yarn:

If they are only testing a foil on one side, and using telemetry to compare with the old foil on the other side then it would be better not to have a mast which would cause different loadings on the 2 foils, either because of lateral wind, or because even small roll in the boat causes the top of the mast to move quite a lot.

Without the mast it will be far more even

New arbitration

So they can add fairings to the mast, but cannot put backstays inside those fairings. Correct ? 

I'm pretty sure this isn't the last chapter though.

 

[Thewas]

sound bizzarre: the RC considers as "backstays fairing" something that's not attached to the stays at all. Man, we'll end up to the Big Bang walkin' down thiz path...
