Using the old foils makes perfect sense to me. The first thing I'd want to do is established that my new boat can go as fast as my old boat with the same foils. I also think the main sheeting system looks brilliant, I'm surprised we didn't see this earlier.

[@andrewdillon7837]

I bet they have "Secret" foils to put on ,,Can't show everything at the "Launch",,, Mega bucks to show the investers ,,, Looks cool , but what would i know,,

[@mark-ish]

Smart thinking. At what point does the rules lock down the foils be swapped?

[@thisismyspout]

Its more a case of not exposing our design and giving other teams time to copy it. Hence using the old foils

[@thisismyspout]

This was often the case back in the later 90s and early 2000s is run on the old keel until its closer to race time

What a beautiful looking AC75! This boat already looks fast, stable and low to the water line. Even on older foils. Will be fascinated to see how fast this boat will get with all the tweaks and changes it will under go between now and the defenders series. A boat like this and a crew like Burling and Tuke this will be combination that will take some beating. Good luck to the challengers.

I love all the technology and innovation around the AC, despite knowing nothing about sailing. What's so fascinating about these new AC75s is how similar they are, especially LR and ETNZ. Can't wait to see them racing

Interesting video 👍

[@davidpicken6879]

Does the camber on the bustle give an indication of how trim could be used to increase the effency of the sails? Bow down mast raked forward (see forward raked wins on aircraft) reduces the tip vortex and associated drag but there are control issues some of which are mitigated by only having 1 wing.

[@SilvanMarty]

Trench looking learned from luna rossa? Foils now must on for AC in barcelona? what about sails? They still able now using foils and sails from before and changing to real cup stuff later? Thanks telling my question about foils... interesting see end of sail and sail controll. Im not counted how many after rules every team built already.

[@VECTOR_HUNTER]

[@macscott5290]

Do the old foils count in the number of foil models they can have this time round? Whatever the case it makes total sense to benchmark all the changes to the hull, rudder and rig against the old foils before locking down this years foil designs. Great video!

[@fluiditynz]

I'd be flying them out and I'm a kiwi. As a wingsurfer and hobby foil designer, there's always more tweaks you can put into a foil 😁

[@georgerussell8948]

Mind blowing tech. It’s seems a pity it’s not being contested in NZ but if the Kiwis get up in Barcelona then it will stamp them as one of the worlds greatest sailing nations. Frank Worsley would be utterly amazed and mighty proud of his sailing descendants. Go ETNZ.

[@pierocostantini2864]

The super interesting thing about this ETNZ setup is that they used 4m old foils instead of the 4.5 new ones. Okay, it's a ton lighter, but it shows a huge confidence in what they've done.

[@bwtcf]

The first thing that jumped out at me was that the mast seems further aft than on Te Rehutai. There seems to my unscientific eye to be (possibly?) more foredeck length in front of the jib tack as well. I am wondering if this indicates: 1. the sail plan is further aft as a whole; and 2. the sail plan is higher aspect (as a whole)? This would (if it is the case) seem to indicate a conscious choice to top end optimisation, and I was expecting there to be a MASSIVE premium on achieving lift off in lumpy seas and light airs. I understand this is a trade off, but would be interested in your detailed analysis and the 3 of you discussing: (a) Is the mast step further aft (i) overall; and (ii) relative to the foil arms? (b) Is the sail plan as a whole higher aspect ration than Te Rehutai's? (c) Is there more deck length forward of the jib tack?

[@georgesnoek4628]

Yes. The move of the mast backwards does look like it to me to. It will be super interesting to see all the boats in a side on comparison!

[@bwtcf]

The foot of the jib looks long to me. kzbin.info/www/bejne/Y3WZZXx9fdR8r5Ysi=_lx9Ldc-cdA0fftw

[@tweaktalimited2222]

Looks like it will sail like a hot knife through butter

[@tpurves]

These things are looking more and more like something you would see flying around Lando Calrissian's cloud city in Star Wars.

[@ricklyons6197]

The way the transom pinches in will probably be faster when in displacement mode.

[@jamiepb123]

Would it be fair to say Orient Express will be identical - coming from the same design house. My hunch is (putting it out there) LR will look similar to ETNZ. INEOS and ARBull will be of similar design. AMagic will be somewhere in between (unknown?).

[@jamesaron1967]

Hopefully, every boat will be distinct beyond their livery. I'd hate to see identical hulls emerging from the same manufacturer.

[@kiwijonowilson]

The new boat looks pretty nice to me. Proof is always in the pudding though!

[@rodboese7041]

Berlusconi in an interview has just stated that the sails extend down to the water which when you look at the new boat sailing and the deep bustle i understand, would be interested in your comments

[@qksmith]

can you tell if they have the same number of stays. its hard to tell as they seem to have a backstay in some photos but not in others. are they all running inner and outer side stays and single forestay and no backstay

[@carbonarne675]

Your fast again

[@Jamespaintsplastic]

Do you think they fitted the old foils to get a like for like comparison to the performance of the last boat? If the foils are the same, then they can assess their new control systems?

[@MozzySails]

true, they must have lots of data on those old foils. Although out and out performance probably isn't the main aim for now, they're probably still designing control systems and trialling them for feasibility

[@jamesaron1967]

That's _exactly_ what I was thinking (it's how I do things myself) along with possibly not wanting to reveal their newest foil iteration too soon. However, the latter reason is much less critical seeing that ETNZ was already advanced in foil development.

[@johnmartin7158]

I went down today to see the Team NZ boat this morning before being towed out to the harbour for its training session. Very intriguing to me the 2 levers at the stern. All other boats I believe have only 1. According to a technical expert standing next to me this will definitely be an advantage. Also this expert was impressed with American Magic. Cheers.

What do you think is most important, foils or hull shape

Foils in my opinion. However Barcelona is an unpredictable venue and it could turn out differently, we'll see.

[@davidrhodes7655]

Designed to reduce drag

[@dadcooks1347]

I think ETNZ are intending to be foiling 100% and have designed as such. They have refined the hull shape to be as slippery as possible through the air. The bustle is purely for end plating, not for touchdown/takeoff. That’s my take anyway. Can’t wait to see their new race foils, and some speed data at that time.

[@derekness7900]

Interesting-if you’re foiling 100% of the time maybe “old” foils are faster as I presume new foils are larger and draggier

[@scotthallinan5729]

Hi Mozzy you didn't mention Team NZs boat has a guard rail all the way round it there last boat didn't I hope they take it off when sailing as it will cause drag and windage dunno why they put it on there no other AM cup boat has one.

Mozzy ignore the pronunciation pedants. Language and pronunciation evolve just like Dialects and accents etc. Māori is no different. Plenty of us scramble ( to some ears) English also …. :) Like others, very grateful for your videos. Cheers.

[@nedoneil123]

Look at the video attached. kzbin.info/www/bejne/bGm4p2d4lJupr9E Look at 55s. Are the foils not parallel to the centre line? They look splayed out but why would you want your leeward foil to track you away from the wind? Would be good for down wind but bad for upwind. If anything like a trim tab on keel on the old monohulls you would want the foil to track to windward. Does can't angle change this logic? Or is the angle deceptive on the video. I will let you investigate :)

[@deandavey7849]

Fly kiwis ❤👍🇳🇿🤗

[@Trajectionable]

thought I'd pop in just long enough to gauge how unsportsmanlike the keewees are this time round...

[@ScottSummerill]

So, why wouldn’t they fly the boat in like AM? Makes no sense to ship. What does that time scale look like? Time lost not refining the new boat. Maybe they think the lost time is ultimately not relevant as they are now pretty experienced with these boats?

[@MozzySails]

Good question. I think the cost would be significantly more from Aukland and need stops. Maybe they feel that if they can get the hull commissioned, then re-focus on finishing foils which boat is in transit, then they don't lose as much. After, foil design is probably most critical and an early launch with old foils buy them more development time.

[@actiaint]

Cost! Exactly same reason cup not being defended in Auckland as more income taking it to Barcelona. Yeah, i woulda made the challengers pay for our transport north.

[@geofflowe7237]

I sure wish they could do it here at home in Aotearoa, but I accept the argument they were much less likely to be able to be able to afford a winning defence if they stayed at home. On the subsidies... They weren't actually that much over the years. In fact the majority of the spend by central and local government on the Americas Cup in New Zealand has been on infrastructure which we're all benefiting from now (in Auckland, at least). Any investment made in ETNZ has already reaped a significant return for us tax payers, so they really don't owe us anything for past "subsidies"! Bear in mind, ETNZ's mission is to win and defend the Americas Cup. Simple as that. There's nothing in there about maximising sleep and convenience for those of us at home!
