Best looking boat, but no sailing for weeks and not even a hint of a foiling tack. 

Brits are already unloading in Sardinia and could be on the water before Prada are back out. Looks like they're losing their advantage of having one year round base (over AM and INEOS)

The Italians with Prada sponsoring beautiful handbags etc have advised Luna Rossa we know you can't win but as long as you are the prettiest boat we will be happy.  It's always been that way.! As long as my arse points South the Italians will never win the Americas Cup. ATM it's been America, New Zealand, Australia and a rogue Kiwi based Swiss team that have managed to win the coveted cup.! Can't see that changing unless Sir Ben and his entourage buy the Kiwi Team like Ernesto did with Coutts, Butterworh and Co..!  (Been on the RUM tonight my apologies we need to keep this thread)

- Francesco Bruni is in Perth for the Moth worlds, and is being replaced by Ruggero Tita (Nacra 17 World Champ last year, his nemesis Vittorio Bissaro just won last week in Auckland). No mention of JS

Yes strange re embargo. Was seeing a few LR shots on an Italian sailing FB page but they've petered out over the last month and now nothing.

Spithill would probably be in Aussie training with the Comanche team preparing for the Sydney Hobart. Comanche got out gunned by Wild Oats XI last year so they won't want that happening again. Wild Oats is also fresh off an unexpected repair job so they may feel Spithill can get in Richo's head.

No apology needed.  Fair comment.

If the effort expended on photos and touchy-feelie vids is a fair marker of the LR overall budget, then the Cup could be headed for a new home.   Somehow I doubt it though!

Probably a bit more than that looking at the sea state although that could be left over swell from bigger winds earlier either way great to see them having a blast.

Wonder how well the GP50's would have held together in that?

We saw the AC50 in that much breeze I reckon in bda, but not anywhere near as lumpy. It would be an interesting exercise although I hate watching sailing so close to disaster. Like cowes.

Given their lack of sailing, they look quite safe actually.

A capsize in those conditions are problematic for any boat. Not only do we know that the AC75 has been designed to capsize and recover (assisted or otherwise), but all of the data we have suggests that whilst they wont win the race in the event of a capsize, they will be able to recover and keep sailing.  If we're talking about boats of any decent size, a capsize for a catamaran in the same conditions is catastrophic. The other option is to go back to keel boats, which no-one seems very interested in.

On the original design calls was for it to be "designed to capsize... and SELF-recover...."  

The first capsize by NZ was a gentle roll over in a light breeze, it was in no way representative of a capsize in heavy seas and strong winds.  I think the boat will survive the capsize, but trying to get sailors out from under a mainsail pinned to the water by a strong wind in those seas will be very tricky and dangerous.  You did see the water submersion and roll tests that team GB requires all of their sailors pass?  (it is a similar concept to what US Navy pilots train on).

WTF is your problem?  Does comparing it to a boat that you don't like somehow make it more safe?

The point is a boat that is prone to capsizing should not be sailed in extreme/unsafe conditions.  The purpose of the AC is to determine who has the best combination of design and sailing talent, not to try and turn it into a death defying feat!

Can't explain the obvious.  

We were sailing across Lake Gitche Gumee in late October with trailing winds of 27 knots, 50F water temp and about 10 foot seas.  We were within 30 miles from where the Edmund Fitzgerald was lost when the line to our dingy broke and it drifted off into the distance.  At 15 knots and smaller seas, we could have retrieved the dingy.

But how can you say its "Prone to capsizing when only one has capsized so far? Clearly the AC75 is capable of sailing in heavy air and waves without capsizing! 

How exactly is 24 knots death defying? Stop making outrageous, baseless claims. The only reason the ETNZ AC75 capsized was because they made an error. It doesn't mean the boats are prone to capsizing!

A piece about the video further up, it's in Italian but it translates well ..

Luna Rossa with the Scirocco

By Sailingsardinia   /     Dec 29, 2019
 
The video goes back to training before Christmas, before the whole team went on vacation, it seems to have been shot with a wind around twenty knots and comes just when defenders and challengers discuss the wind limit for the Cup races: the New Zealanders, to adapt to the conditions of the Gulf of Hauraki, they want to fix it at 24 knots, while the others at 20 knots.

More waves than wind, Scirocco (S-E) having maximum fetch in Cagliari. Prevailing winds are northerly with smooth water, that’s why Cagliari was selected for training

I think it looks terribly slow. All the drop downs must slow them down. I guessed it would be easier to fly in strong winds, but seems as if I'm wrong.

No, but it's all of the evidence we have.  I think it's safe to say that this is more relevant than someone sailing across Lake Gitche Gumee.

I did see the submersion tests. If I were designing those tests I would make them exceed the anticipated risk. To assume that they are indicative of what would likely happen in a capsize would be incorrect.

In actual fact, what we've seen in all of the capsizes so far (being one), is that the boats sit very high with the mast step (and front end of the boom) being some 6 feet above the water.  Given the large cockpits, there's more than enough space under the boom for crew to shelter safely.  There is much less chance of significant injury if you compare them to the AC50s where falling some considerable distance, or slamming forward into a grinding station is common place in the event of a nose dive or capsize.

So at whatever weather station that is about 20 knots gusting 30 at midday then, probably unlikely to have been racing in either a 20 or 24 knot limit.

Maybe with luck right on the limit of what 24 knot limit might allow, although in Auckland with multiple course options it would be without that sea state which looked like the toughest part.

Interesting observations, mines are a bit different though:

- the shadows are small thus the sun should be high

- the Scirocco is blowing from the south so the boat is heading north

- the sun is coming from the right so from the west.

So my guess is middle of the afternoon. But I agree the glare in the jib could show a sun a bit more north-west though.

There is some great stuff there.

  1. Not much angle on the leeward arm, so leeway resistance seems to be mostly from the vertical part of the arm, not the foil. I guess that's just the downwind setting.
  2. They get some serious height and the main foil breeches a couple of times without any serious consequences or even splashdowns (though they may touch). See image bellow from about 1:42
  3. Touchdowns don't ship much water over the bow, so little speed lost
  4. Shows how the boat is steered to react to every minor local change in pressure, just like a skiff with asymmetric spinnaker (cf previous stern video of AM?). The big difference with a foiler is that they steer upwind the same way.
  5. Clearly on the edge, but the boat stays very level in pitch and roll. Heave is an issue, but only to be expected in those conditions

Overall, very impressive.

The shadow covers the starboard side of the boat at all times.  I can’t see any short shadows.  Not only that, but high sun wouldn’t produce the kind of reflection we’re seeing at this angle.

This is consistent with afternoon sun.

We’re probably arguing over a couple of hours either way.  The video gives no proof that it’s taken on the same day as the weather data.

They don't have a fckg keel and have weigh hanging off the side of the boat balancing it against the wind, of course the AC75 are very capable of capsizing.  Didn't the smaller training boats (T5, Mule, mini-moon) have a some more violent capsizes than the gentle roll of the NZ boat?

You guy can go and make all of the assumptions about how easy they are to sail, how stable they are and even how easy it will be to swim/crawl to safety when they go over in heavy winds and high seas.  I was just stating my opinion and you can all have yours, but I wouldn't want to be on those boats in those conditions.

Well "capable" is different to "Prone" isn't it. Lots of boats are capable of capsizing. But that doesn't mean they're prone to it.

Thats why you're not on those boats

Little late to the party on this one, but this looks insane!  The forces at play here are mind blowing.  Glad to see LR getting it done in those conditions.  Looks like she struggles a little at the end when she goes close hauled, but they'll get it worked out.  The hull is really different compared to the flatter bottoms of the US and English boats.

Even a Supermaxi is capable of capsizing if you fuck things up, and it does have a keel!

Sorry,but 14 hours, even on a lake, ya don't pull your tender.  You a fool.

Out.

Edit: and before you go on about the storms of November come early, I'm betting it wasn't.

They don't have a fckg keel and have weigh hanging off the side of the boat balancing it against the wind, of course the AC75 are very capable of capsizing.  Didn't the smaller training boats (T5, Mule, mini-moon) have a some more violent capsizes than the gentle roll of the NZ boat?

You guy can go and make all of the assumptions about how easy they are to sail, how stable they are and even how easy it will be to swim/crawl to safety when they go over in heavy winds and high seas.  I was just stating my opinion and you can all have yours, but I wouldn't want to be on those boats in those conditions.

You really are a fool. Go crawl back into your 28ft Ontario and leave the discussion to folk that have a clue.

One Italian guy. Some thoughts on the pitch instability in the latest video.

I don't see how foils with flaps have more instability than solid foils raked like the AC 50. This comparison wasn't explicitly made but I reckon is worthy of rebuttal.

Anyway, thx again Italian Guys.

Can't say he said anything enlightening or useful. So the LR team had some issues with flight stability in what was probably their first taste of borderline conditions - freaking genius observations.

He's talking about heave stability and explains his opinion at about 3:00. The Dali foils, like the J and other curved flapless boards, are self–stabilising in heave, whereas T foils aren't, they depend on flap adjustment. I think the basic physics of both has been explained in detail ad nauseam.

A very timely and astute observation indeed @Brutal

Ok, Sherlock, so how would you plan to traverse the 50 - 70 miles to shore in case the sail boat started to sink?

True. I was speaking of the Ac50 foils, which didn't have self stabilizing characteristics, would have the same tendency of pitch oscillations, and would be the logical benchmark here. Which wasn't mentioned.

Just saying although we saw some shocking dolphining in the 50's it seemed to be pretty much conquered by the time the series started. Early days.

I'm not sure he is comparing this to the AC50 foils so much as to just solid foils on general. Obviously one point is the self leveling design (not unlike the first foils on ETNZ's first Ac72 with the tips that would stick out of the water) that would need to sail closer to the surface than they seem to want to sail these. I'm guessing they just get much more stability being able to keep the foils and that much more of the arm deeper. The second point about the flaps probably has to do with the fact that you are changing the foil chord all the time and changing it's center of lift. Perhaps the boat needs a moving cg with flap movement? Definitely an interesting problem.

Not sure if I think deeper foils are more stable..  But I think probably flaps give you more control and, so, unless you fuck up, you will be more stable more of the time.
