- AUCKLAND NEW ZEALAND November 20, 2020. After five weeks off the water the crew of Emirates Team New Zealand New AC75 Te Rehutai took their new boat for a sail today and looked just as they had been sailing her t every day!. A great display of sailing.

Great video again MIke. I'm more than happy with that for a first day out. Foiling and tacking on the first day out of the box shows the confidence the crew have in the boat. We have to remember that we've only lost the cup to teams with billionaire backing. Teams with unlimited budgets And even then, we've won it back. The ability of this team to out think the opposition is legendary. Ineos have had weeks on the water and they don't look as good as Te Rehutai on day one. A big thank you Mike from darkest Herefordshire . A Kiwi a long way from his natural habitat !
Best of luck with that. The speed data says otherwise. Shouldn’t you be. Supporting info’s since you have the benefit of living in the UK? Only joking, you are very welcome. All will be revealed when the racing starts. Looks like a fabulous venue but not as good as the Solent will be for the next competition. I live near there, come and have a beer!
Money is what the America’s Cup has most always been about. The NYYC retained the cup for 130 years because they had more money to spend, plain and simple. ETNZ is trying to change the game by introducing rules to reduce the money required to compete, and overall I think that’s a good thing, but I simply mean to point out that winning the Cup by spending more money isn’t breaking with tradition, it’s keeping to it ;).
Speed data ? What speed data? Who are info's ? And no, living it the UK has nothing to do with it. I've sailed most of my time in the Hauraki Gulf and Knew Peter Blake. I've been following the New Zealand challenge since a very young Chris Dixon helmed plastic fantastic in 1987 ( I worked with his father Roy ). We can have a beer and celebrate the team retaining the cup ! Oh, and see if you can scrape a decent rugby team together and give us a game ! Cheers !
Glyn, thanks again, Mike
I really love it, amazing how in 2:30 they get to the tack almost with their foil already out
This is the winning boat to me. Well carved and awesome arts from the team.
Best-executed tacks I’ve seen so far. New hull design does seem to lift faster.
AS, may be hard to beat! Mike
She’s a F1 race car for sure. Stunning and compare her with the 2003 defender disaster. Amazing credit to this generation of ETNZ and we’re behind you all the way.
Chris, thanks for your comment, Mike
Great first sail but Disaster is only a broken mast or blow over away. Don’t count your chickens yet. The other boats are serious contenders.
Maybe it's just because I'm old, but I miss the days when they sailed boats in the America's Cup! ;-)
Yes, I remember the day they used horse and cart...miss those days. But you have to keep moving forward, human spirit.
AirflowNZ Travel, Amazing footage mate, & just astounding how you have managed to come from the "AC75-Te Rehutai" launch with all the brilliant videos of that, then get into place to do this for us. I must say, they are really doing well for the first day on the new boat.
Also what is amazing, are the people commenting, on the first day of sailing this beautiful boat. Some of them seem to think that they know the boat better than the design guys who have spent months in the Tank, tweaking away until they have got it right for our NZ Crew.
(Sorry Mike about the little rave)
Gib, still trying to do better! Mike
@@airflownztravel Mate, I've looked at other peoples Vids, & although they are good, yours are exceptional, with that slight bit of professional touch. Regards Gib
Gub, another nice comment, thanks, Mike
@@airflownztravel Haha thanks mate, I might have to change my name
Game over. Thank you for coming down and wintering in NZ.
Kiwi modesty?
Scott, nice comment but I actually live down under! Mike
@@waylon2755 I think they changed after winning the first Rugby world cup. Mind you most western countries are on the slide.
She looks good. First day out and having a chance to feel the boat. Foil to foil gives and Tacks. Lovely nose down attitude. Also, love the fact that the foils are at 60% rake to horizon angle. Lift and vmg in one. Well done boys and girls. Now break the 50!
James, interesting comment thanks,Mike
Just this. Foil talk has started an argument about leeway now, my position is it gets ever closer to zero, my counter reckons they can generate negative angles of leeway as a trade off against drag. I like the principle but my conventional sailing brain can't accept it.
Toby, you got me, another viewer will have to pick up the tab on this question, Mike
Looking very good for 1st day on the water. What's interesting to me is that the foil arms are used in the widest possible position, so in water foil isn't horizontal. So much so that the outer tip is clearly out of the water. Presumably this angling of the working foil to windward gives her lift out of the water and lift to crab to windward.
Most of the teams seem to do the same thing. It seems strange but it’s a consistent approach.
Robin, interesting observation, Mike
The reason is that the foil has to double as the centreboard, not so much to crab to windward as to resist making leeway -- and the latter is almost as important downwind as up, because in both cases they are sailing at the same apparent wind angle, in other words, the sails are just as closehauled "downwind" as up. Unless they stuff up a gybe, it is effectively a tack, with the flow on the sails consistently aftwards (from luff to leach) throughout the manoeuvre.
These are the first sailing vessels in history, as far as I can ascertain, to exceed an upwind Vmg of 20 knots.
It IS (I think) an interesting point to speculate on the extent to which they could optionally "crab to windward" rather than just point higher, but I guess it would have mainly tactical benefits in making it hard for the opponent to judge if they were laying a mark, or able to cross ahead. Accordingly (I speculate), the less often it was used, the more beneficial it would be.
Think of the overall structure as a trimaran.. once you’ve got the foil-arm tips extended to the max beam, the righting moment is maximised.. then the foils themselves have an inclined aspect, like in a moth when the boats are heeled over to windward. The foils then perform something additional to mere lift..
10 Years ago, this boats would have been unthinkable, not enough computer power, not the precision, the machines to build, the material to use. Without Formula One, America's Cup, Tour de France,... allowing money for science to advance, we would have only wars to pay for science. Maybe one day, humanity smartens up and exchanges religion/greed for science to achive new wonders...One can dream. Beautiful Machines, no motor, wow.
Otto, great observation, Mike
Extremely impressive ! From all I have read this boat 🚣♀️ is a real leap forward and also in NZ sail design. Helmsman Peter Burling will really come into his own in this class of boat and knowing the waters inside out.
Very much looking forward to the start of the regatta.
Auckland. John
John, she will be very hard to catch, Mike
Straight of the box going well. Great footage! Ta!
Glen, yes and thanks! Mike
Looks beautiful and fast. It will be a fun Cup to watch! Thanks for the video.
Sakster, Thanks for watching! Mike
Total beast! Can't wait to see them side by side... Great video 👌
Thanks! 👍Mike
A look into the future! Still Thursday the 19th here. I hope they have enough elbow room for the grinders. Thanks Mike!
SC,Fingers crossed! Mike
Great footage, thank you. All looks good for a first run. I am now worried for the other boats.
Emil, thanks for your comment, the results will be interesting, Mike
She is looking really sleek, fast and beautiful, thanks 💯👍
TD, Thank you too! Mike
Fastest canoe in nz
What a beautiful sight. Poetry in motion. :)
John, thanks, Mike
nice b̶o̶a̶t̶ ground-effect based sail plane
Miles but very Cool! Mike
Champion skipper on the helm Peter Burling and Blair Tuke untouchable. Yes shes very fast just inches above the sea. Go Team NZ.
Tony, great comment, thank you, Mike
The tacks look pretty aggressive...but lightning fast already! Keep it up ETNZ!
MK, we could have a winner here! Mike
@@airflownztravel Hope you are right! As a german who has gone to an italian school I should probably cheer for Prada. But when it comes to sailing I always supported the kiwis. ✌️
MK, thank you for your support, Mike
That's amazing it looks like its doing 30 knots with no sails up.
Do you mean at the end when it was being towed back to base?
Yeepppyyyy so enjoyable to see team nz speeding...
Thx guys 💪👍🍀🍀🍀🍀🍀
antje, she does look great, Mike
Let the reserve teams allowed to race on Gen1 boats. Make it interesting!
Mark, the mark 1 boats have been decommissioned, it would take weeks to get them sailing, Mike
Nz’s boat one will likely never be sailed again. I think that structurally it’s ‘spent’..
I wonder what wind speed was like? Looks like kinda light breeze, not much in the way of white caps on the water. This boat sits really low and stable on the water, they just look comfortable out there.
Shane, about 8-10 knots, Mike
wow, that looks pretty quick to me
RKT, she sure is, Mike
Amazing that thing even flys without sails... 5:00. ;-)
DU, yes but it has 1200 HP at the end of the tow rope! Mike
@AirflowNZ Travel Looked like an 8 knot wind?
Rick, about that, not much strength in the breeze, Mike
OMG they are absolutely fanging it at 1:00
Wow how smooth and fast is she's Sailing she does look fast also there are more developments to come
Rich, great comment, thanks, Mike
Does too much gap between the hull and the water make the boat change the speed of the boat ?
Yes so high pressure escapes from under the boat to the low side and in turn you lose lift you have to look at the sail as a airplane wing stood up you have low pressure on top of the wing in this case a sail high pressure on the bottom so then you have lift or forward moment. So some of the teams are trying to seal this off to keep pressure where they need it more pressure faster boat well that's the theory. There is a fine line to sealing off pressure to sinking your hull in the water who has got it right your guess is good as mine.
There is a lot of talk about the foils but the rudder foil is critical too . Are there different variations being used ?
Gary, not much, most comments seems to revolve around the foil shapes, Mike
No major control issues. A great success for a first sail. Seemed a bit short -I suspect some reading was not giving confidence.
Sky, not bad for day one! Mike
I saw it from class yesterday! Cant wait!
Hope you enjoy it!, Mike
Looks fantastic, seems to fly/sail superior to others. Go team kiwi.
Martin, nice comment, thanks, Mike
Did anyone notice the water distribution coming off the foiling arm it looks different to the other boats question is the wing tips on the end of the foiling arm different lengths the inside wing looks longer when travelling close to the water I thought I saw the outside wing breaking the water?
Why didn't they put their spinnaker up? Ha ha ha
Loyal to the foil!
Dorothy, that's great, Mike
This thing is unbeatable, you heard it here first.
WO7, us Kiwis hope so, Mike
Impressive. A wing with sails.
Hone, and she really flys! Mike
Quick out of the box!
Antonio, and down the back strait! Mike
I so enjoy your posts. This footage, of interest in that the foil pair selected, as I could make out...was of horizontal twin. This is variant to the recent US choice as twin with degrees of downward angle. The recent Brit...W shaped matrix as lifting body.
*what an interesting tech arena. clearly, available to tune as speed, lift angle.
While difficult, I think the metric as speed across water is very similar.
I hold the view, everything at the race will come down to crew. Tactics, (*start box) selection to tack, momenteum thru gybe...I hold the opinion. "the helm will be critical".
And of impact...sail selection. I did note a slight, mast deflection. (toward stern)..
which I hope to compare to the challengers..
This arm chair salt... of half a world away...spirit...quite cheering for all of the crews and
helm domain who compete. So well done. I should very much like to ride at near
bowsprit....as I judge that place...satisfying indeed. Can this bold crew defend?
Mark, you have covered a fair bit of water with your comments, many thanks, Mike
@@airflownztravel I hold the view, the Kiwi dominance shown to recent cup challenge is a product of the beer selection as best instance, strength of crew...and I so hope to mirror that well found strength and resolve. Clearly,
that sturdy lot has found advantage before. Can the challengers
meet that plateau? That podium place demonstrated? Top form?
Mark, they certainly will be trying, Mike
Emirates Team NZ you glorious bastions of technological advancements. 🤯🤯 Good luck challenging that!🤣🤣🤣
DC, nice comment, Mike
Best look yet of the strut flare. . . still not certain what's happening. Less outward spray? I always thought the drag penalty on the strut was huge, is this addressing that?
Dean, will have to keep looking out for awhile to find out, Mike
@@airflownztravel i've lost track of how many times i've watched this. Best footage so far is yours. Shows more of what is going on, and you got an amazing shot of it (around 2:24)just as it passes in front of those bushes, then as it goes away, pulling up. I've met some of those guys, they are super smart. Way ahead of the game. May the best Kiwi's win.
Dean, nice comments, thanks, Mike
Looks fast and smooth
Stephen, she is! Mike
Ohhh shit..... Lookout Sir Ben..... They are a bit wobbly but could be a threat..
Roy, interesting comment, Mike
She's a gem
Mark, nice sparkle also! Mike
Монохул быстрее катамарана. Круто, конечно. Чудо инженерной мысли. Хотя это уже судно на подводных крыльях, наверное и яхтенная классификация применима, когда оно в водоизмещающем режиме или на глиссе, не знаю, мне так кажется.
Credo sia un po faticoso passare tra la randa e il fiocco ad ogni strambata specie con onde formate ?
Marco, these sailors are really fit with good endurance, Mike
@@airflownztravel ok Mike
Tks for share with us passionate for sailing. Take a look at the speeed on tack, spetacular :) Is it possible show the speed during the course?
Renato, thanks for your comment, when the races are live on TV boat speeds will be showing, Mike
Are they useing bikes to grind?
Richie, not this time, the generators are being turned with upper body arms, Mike
Nailed it.
JL, they surely have! Mike
The foils run very shallow. I'd be curious to know if that would be an issue if there was a bit of chop on the water. Do they just run the foils deeper and if so does the change in roll angle and drag on the foil arm effect the overall foiling dynamics?
Steve. I think if the sea was rough the winds would exceed race limit, Mike
@@airflownztravel ah interesting. Thanks!
Noice ....first day and pretty smooth
Bruce, Yes it was, Mike
I’d love I know what speed it bottoms out at through a tack. It barely seems to slow much at all. Overall looking very quick.
Alistair, with more to come!, Mike
The foil tip spends a lot of time piercing the surface on these flat foils, any idea why this might be desirable Vs the foils with more anhedral staying clear of the surface?
The attachment angle, as available to recent post clear of the water, seemed to my eye to exist to a slight protrusion of hull shape. It may be the fixture of arm...may limit the depth as lifting wing. As a value of the build. I suspect planned advantage.
And, I have been noting the slight (minus angle v form, (US), W shape (Brit)..modifications. *also, length. so I expect furious development.
I think selection may be as wind forecast, a condition as planned best result. Enjoying your critical measure...and cheering the crews,
support personnel. M.
@@mcgama88Not quite the answer I was hoping for but worth noting for sure. Keen to hear anyone else's point if view.
When it comes to the current version foils we only know that one of the teams is wrong. Inline vs dipped, or Ineos 50/50 W version which may have the minor advantage of putting the inline section slightly further away from the arm pivot. If we break down the lift vector into a vertical and horizontal component I think I prefer the dipped version where the most outboard section is the most horizontal giving the greatest leverage. Foils breaking the surface just seems like a no-no, but maybe that helps keep the vertical component in the 'goldilocks' zone for passive ride height control.
@@Toby_ATG Passive ride height was one of my thoughts. Also maybe a drag reduction device? Fully submerg the foil at low speed for take off and allow piercing at hight speed, would reduce lift coefficient which is compensated by flow velocity but reduce overall drag? The NZ foils my quite high aspect ratio which would suit this effect more than a low aspect foil?
Toby, you have done your research, many thanks, Mike
Weight forward, crew going around mast and smaller jib just looks right. Question are they going to do closed course or will it be open course?
Scott, the course will be straight line, 1-2 mile long, Mike
@@airflownztravel Then windward / leeward with boundary lines - I guess geared to undetermined (Covid dependant) number of spectators viewing.
Scott, the media were talking numbers today, about 200k for the Christmas series. Some shops are concerned about lack of access for shoppers right on Christmas when some roads will blocked off. A few charter boats are advertising already to follow the races, guess they will just have to park up at either end of the course, no way of following like in the past, Mike
Quite unstable for now , looks like very low drag foils as they couldn't even turn without touching down inside a patch of higher pressure. A long way till the cup though
Well considering INEOS looked like a hippo stuck in mud today while ETNZ and PRADA were foiling nicely, I’d say the Brits have unfortunately built themselves a light wind pig and will be doing some reconstruction over the holidays.
@@fabmanly1070 Not from where I was watching!
Will she come out and play with the other three😲
GM, I am waiting for this to happen! Mike
Isn't it other four? Or am I missing something?
1. "Circolo della Vela Sicilia" with their team "Luna Rossa Challenge"
2. "New York Yacht Club" with their team "American Magic"
3. "Royal Yacht Squadron" with their team "Ineos Team UK"
4. "Long Beach Yacht Club" with their team "Stars & Stripes Team USA"
When they lift the hull on a tack they look like the desert lizards lifting their legs
Looking great for day 1 😎
Sue, Can't wait! Mike
It rained a lot yesterday in Seoul, Korea. The cold winter began with the cold wind blowing. / I hope health is always with you. Thank you. ^O^
Nice day down here today! Mike
Gergeous!
Mike, she sure is, Mike
It doesn't lift that much comparing to challengers. That's obviously a design choice. We'll see if it brings more speed as well.
Francesco, we should see some results re speed soon! Mike
@@airflownztravel brilliant Mike, any chance to arrange a video showing the outcome? :)

FF, in two weeks we should have a better idea! Mike
LOL 😂 Just like how Te Rehutai smoke Luna Rossa on their first pre Christmas match? Come March 6th it’s going to be a spanking! 🤣
Beautiful, but I can't see any sailing boat, just F1. Faraway from Valencia 2007.
21st century....keep up or get left in the stone age.
@@brucefale6132 about the boats?
The wind tunnel effect with the high sides is lethal, this was perhaps Britannia One thinking, but they didn't quite pull it off. Needed complete separation from the air disturbance of the crew . Also the flat sticky bottom on Britannia One was an obvious mistake. Watch ruclips.net/video/yLc5qsJVu5U/видео.html and pause on 2:00 to see my point.
-pilots,- -sailors,- pilors or sailots?
Michael, grinders, flight controller and helmsman will do, Mike
wow that rear view @3:15 is incredible
GUM, thanks, Mike
Yes, interesting. That rear view shows that the deck design looks somewhat similar to the former multihull.
LR will be nervous that ETNZ have jumped ship to be inline with Britannia design thinking. But ETNZ should be very nervous if LR becomes the final Challenger....and of course AM maybe the dark horse.
Jamie, interesting observation, Mike
Stunning! Ive studied all of the footage of all boats you have put up Mike. Repeatedly over many times! Watch ETNZ 1st sail is wonderful. It appears to me that The foils are sitting right next to the water ready to drop in at any moments notice? The boat is so wide at the stern. So is it... the game not to reveal anything like this making it too late for other challangers to physically change their hulls? Would there be time ? wow there's hopefully going to be some great racing. Thank you Mike for this brilliant 1st footage.
SLS, great comment, thanks, Mike

Man this boat is fast. I was worried about Ineos before, not anymore....
Santos, she is specially fast in a light wind, Mike
AirflowNZ Travel I've speculated as much but it's good to get some firsthand Intel on the gulf. Excellent work by the way
Santos, thanks, Mike
Way cool
Glen, thanks, Mike
Nice 👍
go you beauties
CR, yes Sir! Mike
How quick are those tacks and gibes ..
Michael, they sure are, Mike
she is under tow on the way in, what happened to the sails.
Sails are on the support craft. Crews don't like to waste time ever, there is the gym, debrief, etc. so they tow fast, in and out.
Little confused...
They say a soft wing on this boat and it's made from steel.
The last boats wings/sails were hard, and we're they not made from carbon fiber, a cloth?
Dang these constantly rules stuff and the technology,,, is totally confusing.
You guys have to start making this stuff easier for the fans to grasp!!!
Kevin, the last boats had aircraft type sails, a synthetic cloth placed on to an aircraft type wing with ribs & stringers. These new boats have sails made from a fabric type material. Actually they have two sails that look like one. There is an air space between sails, confused, don’t worry, we all are!Mike
Maybe we from LR have been too conservative with our boat 2..if we had decided for a different project for boat 2 compared to boat 1, now we could have two different options, instead of one.
Giovanni, boat 2 is very fast in light winds, Mike
How can you move faster then the wind 🤷🏻♀️
Thomas, it’s called apparent wind where the yacht can travel at 3-4 times the wind speed. Ice yachts have used this for over 100 years! Mike
So I am pleased that Team NZ seem to be progressing well and hope they successfully defend the cup. But I still think they are stupid boats. As a side note, it is VERY slab sided isn't it? Presumably to get the ballast (crew)as far out to the edges as possible.
JS, the end result will be interesting, Mike
Also a comment,, these are the craziest thing's with all this tech, please get an old fashion tripod to mount the camera from jerking... Thanks
Red Bull needs to get in this.

Nice look, but appears to be a little slower that some of the others.
fly high
Per, but not to high! Mike
Sarebbe interessante sapere il peso del difender !!!
Armando, I understand that all the foils have a standard weight requirement, however the hull, which is really a top and bottom shell moulded together to form a strong structure, is we’re weight is saved by each team. Mike
she looks pretty slick anyone know the differences between our two boats and other teams? what's going to win us the america's cup again who's fast who's slow? or won't we know until there's racing
Jeremy, guess we will have to wait and see, Mike
Sembra andare bene, sono in fase di sviluppo per capire la barca, sarà la squadra da battere.

What’s the point in putting an engine in a sailboat?? Dumb idea.
Never mind, boys. I'm sure it will get faster.
Malcolm, 48 is the max of some of the contenders at this moment, ETNZ hope to break the 50kts barrier, Mike
Allot of touchdowns happening..
Tony, early days! Mike
Looks like it’s a little less stable than the others
Give them time.
@@dulls8475 oh that’s right it was their first time out
@@donb4138 To my mind she looks good for the first time out.
Don, not bad for their first time out, Mike
Regarding stability, you also need to bear in mind that stability and manoeuverability are at opposite ends of the spectrum. The more stable you are the less manoeuverable you are and vice versa. I’m from an aviation background and for comparison look at a fighter jet compared to an airliner. The fighter is probably close to 95% totally unstable, the opposite of an airliner. I would imagine with the boat there is a very fine point that they are trying to achieve where the boat would need to be “just“ stable and no more.
getting close nowcast wait
Barry, all the yachts out next week! Mike
@@airflownztravel can't wait for the 17th its going to be epic

Struggle to foil ? 🤣
What are you talking about dude? Haha.
The crew are sailing her close to the sea on purpose. Iam not sure why
One would think any contact with the sea would slow her down. However Iam no expert on marine dynamics.
@@tonyjennings1025 they try to sail out of the water but as close to it as possible to grab as much of the air as possible, while letting as little leak under the boat as possible. At least that’s my understanding.
@@johnhamburger8811 The higher you lift out the water the more unstable it is. Just imagine a chair with really high and narrow legs, it will wobble all over the place if you put your weight a little off centre. Then imagine a really squat chair with wide legs that is low to the ground. There are also more complex aerodynamics that could be relevant such as ground effect and preventing high pressure air from one side of the hull mixing with low pressure air on the other side (that's why UK and Kiwi's have that thick line running from bow to stern on the boats).
can't
