Interesting discussion earlier by Boink. All very good points. If you can create lift via the hull and foil arms to assist with flying you can reduce the foil viscous drag by reducing area. Even a very  small reduction in foil size will provide a overall speed increase. The hard part is matching the hull lift effect and the foil lift requirements to get the hull out of the water in the first place. And the winner is?

AC75 Class Yacht.
That's in the class rule, I was quoting the protocol, which in §59 has:

AC75 Class Yacht means a yacht that complies with or could comply with the AC75 Class Rule;

and in many places uses yacht as in "…the winner of the Match will be decided by the first yacht…" but also frequently uses "AC75 Class yacht", so the meaning of "yacht" is from context only.

Whether B2 is used during the Christmas regatta is probably the mute question.
Autocorrect shenanigans? 

Hoping you meant "moot" not "mute" - because for those with Dual Burden, this could become a pillar for a good deal of misappropriated "knowledge"......... And there is enough of that already to navigate (and tolerate).

I think it's pretty clear in the Protocol that "two boat testing" only applies to AC75s:
So in theory, a challenger could make a mod to their compliant B1 - like an extra long bow sprit - that would make it non compliant, thus not being an AC75, and conduct two boat testing with that? Clearly against the spirit of the rules.....

No, they covered that^ kind of thinking with the surrogacy rule. If you acquire a hull over 12m it counts.....

And what is new here ?

we have been through this ... if the hull creates lift you are effectively reducing your righting moment which means less power in your sails.

I misinterpreted the tolerance of 1% as being ±0.5% when it's ±1%, so actually ±65.2kg.

I'm sure things can be optimised for boat 2, I just don't see that there are huge weight savings in hydraulics. What do you think is the weight of the hydraulic systems and how much can be saved,  5 kg?

Even if there are weight savings, where could it be used to advantage? It can only go to stiffening or strengthening something in the hull as the boat must still weight at least 6,454.8 kg. Maybe you think the boats are struggling at the upper limit and need every gram they can scavenge for carbon to make the boats strong enough?
I seriously doubt there is any significant weight-saving in the hydraulics. They would have optimised the hydraulic system components in AC34 and AC35 especially, and  unless someone has come up with some new super lightweight unobtainium for the cylinders, there's nothing new that would justify any mods or changes that increase failure risks.

If anything, their partnership with Maxon suggests they may have simplified the hydraulic system by using Maxon motors for rapid-response actuation. I read somewhere they have some 30+ motors onboard.

What the fucking fuck?? Wild news from the team...

https://emirates-team-new-zealand.americascup.com/en/news/454_INFORMANTS-OUTED-BY-EMIRATES-TEAM-NEW-ZEALAND.html

Six months ago Emirates Team New Zealand and ACE (America’s Cup Event Ltd) became suspicious that we had informants in the event organisation (ACE), and these suspicions were confirmed when we had confidential and sensitive information coming back to us from Europe very recently.
The motives of the informants who had access to the Emirates Team New Zealand base can only be guessed at, at this stage.

In addition, these people have made highly defamatory and inaccurate allegations regarding financial and structural matters against ACE, ETNZ, and its personnel.

These allegations are entirely incorrect.

As a result, the contract of the informants has been terminated.

Although these allegations are baseless, MBIE have no choice but to investigate despite our belief that the motives of the informants are extremely suspect.

We are working with MBIE to close out the remaining issues with them quickly.

Emirates Team New Zealand and ACE will not let this set us back in our America’s Cup defence or hosting of a great event this summer.

Now this is what the America’s Cup is all about. ETNZ has had spies in their ranks. Just when business was starting to pick up on the water, the off the water shenanigans are starting! Impeccable timing!

Sh&t will hit the fan when they find out which challenger he has been working for!! 
I sounds more like someone in administration/accounting, leaking information and making "impropriety" allegations over some expenditures {eg allegations about payment to ship Dalt's race car to Aussie).

"This includes claims around structural and financial matters. We are working with America’s Cup Events (ACE) Ltd, and Emirates Team New Zealand in relation to the claims made," said Iain Cossar, General Manager Tourism.

If the information was "Incorrect" as TNZ say then the informant or informants should be auditioned for "Dumb and Dumber". So they acted as Spies and got their information wrong. Yeah that should get them the gig. FFS
