Been glued to the entire series for years now on the run up to the 37th. You always manage to point out 'stuff' that I've completely missed. Makes the entire event all the more interesting...cheers guys.
You guys didn't talk about the big differences in mainsheet control and the impact this might have on aero efficiency. There were times in the round robins when TNZ looked like they could sail with smaller sails and hence less aero drag which might be as a result of their better aero control. This might give them an edge upwind which, as Rob suggested, is where the biggest opportunity is to gain control.
True, completely missed that bit we had spoke about it before. It will be interesting to see ETNZ stern camera and the actual utilisation of thier twin mainsheet set up
Thank you so much for all your videos examining the tech and techniques of the teams in this America's Cup. It would not be the same without your analysis.
I have a wild guess that LR's starting strategy was constrained by the limited manouverability of their boat in tight manouvers. They had had a couple of skids in pre starts earlier in the series and might have decided to stick to a timed start because of that.
Just a thought.... Seeing as INEOS dev was powered by an F1 team.... Have they utilised the disturbed air coming off the platform as a design feature? This is certainly something F1 has experience with (hence they've changed the rule in F1). The stabilizers on the upper rudder housing? The twist of air flow across the belly of the hull? Hmmmm..... Love the content! Thanks man!!!
Not necessarily. Brave design decisions killed them in '03 and the boat was a dog. We know the kiwi boat's not a dog because they sail alongside the challengers for a good chunk of the LV cup these days, but I suspect the boats won't be too far apart speed-wise.
As a half Kiwi I'm supporting those boys but if they're gonna lose I'm glad it's Ineos. We won't know until after the first two races

Great chat as always gents. One thing you didn't touch on was the effect/role of the leeward helms and trimmers too. The leeward helm is probably doing things like course calculations and monitoring the wind situation, but the leeward trimmer (and sailing cyclor) could be monitoring/adjusting all manner of things. Have heard Ben (I think) say 'My Trav' a load of times as well, so there is possibly a bit of steering/power combo for the windward pilot going on. Ineos' trimmer position being at the back would have a better view angle to the foil to monitor ventilation etc as well.

@@lighttness To be fair, it'd be a mistake to assume that the data we have gives us a decisive picture on who is faster.

To be honest, I don't think speed is going to be the deciding factor anyway, it'll come down to strategy, build quality/reliability, then speed and of course a bit of luck.
Really interesting conversation. My thanks. PS Also your insight on the live feed on YT - between you and Jemmet (Jon Emmet) there is a lot that adds to the experience .
Love your work Mozzy. As a Aucklander I was originally strongly opposed the choice to hold the competition in Barcelona. In hind sight I think its been the best move for the Americas Cup. I love the variability that this open ocean venue has brought to the racing. The sea state and winds have elevated the demands on the teams and brought in an element of chance that an inshore venue might never bring. Every race has been a outstanding display of walking the knife edge. I mean how nuts was the final of the LV?! If this racing was taking place in Auckland i reckon it would have been boring af by comparison. Happy to eat my words on venue choice, despite not having the magic vibe in my home town. I would love to see the kiwis take it out again but to be honest if ineos win then its may well make things even more exciting for the future of the cup. As a spectator I'm all for that! Either way we can't lose. I'm super excited for this to kick off! How lucky are we?!
Another kiwi here, totally agree. Except for the handful of times they were on course C, Auckland was flat and steady with no passing lanes. Barcelona has given us something new most days!
@@sjc9832 But there wasn't a single pass in the entire LV final, that's been so disappointing. If you look back at San Fran 2013 for example, the first 10 races or so the lead changed so often as one boat went across to have starboard advantage on the next cross. The boats were forced to tack and gybe much more. This series has been pretty boring, especially the downwind legs as the leading boat does about 3 gybes and they're at the mark, no overtaking, you are pretty much relying on the guy in front falling off the foils to overtake.
@@Codetapper there were a few passes in race 9 and in the abandoned race, while the 2013 LV final had no passes and the same boat led at every mark (except when NZ's boat shut down while they were leading in race 2). I agree the 2013 AC was amazing, but so was the USA vs ITA semi this year. It's really really hard to create the conditions for competitive match racing in a design competition, and I think they've done pretty well here.
Counting down the hours... I think this cup will be amazing viewing, just from a racing/tactical perspective, let alone the speed/technology. I'm a Kiwi and I really want TNZ to win, but if we had to lose it to anyone, seeing the cup held in the UK would be pretty cool. Bring it on!
Another kiwi here. I’m still pissed at Etnz for taking the cup to Europe so I’m happy for them to lose. That said I’d have preferred them to lose to Luna Rossa. I’ve been glued to every AC since 1987 but this one has been a bit meh. The fact that racing is from 2-4am hasn’t helped. The racing has gotten closer and better but not a single pass in the LV final?
One of the unwritten rules of the America's cup is always have a big chunk of pace that you keep in the bag until you reach the final. Linked control software can be very good at hiding the boats true potential.
it seemed to me that in the pre-start Ineos was frequently putting themselves in position to "sweep" in front of Luna Rosa, just like a fan to suck their wind and get them off the foils. They would flick around so fast that it must have significantly disrupted air flow
The ETNZ ability to flatten the windward sail in light airs makes them unbeatable. power over anything else wins. if you look at the cross section of any high lift aeroplane it is a thick wing with flat underside and rounded underside. hence lower pressure created on the upper side equals lift. on ETNZ it means massive power differentials to the d mo.o leech control wire
Re your last point. Freddie let slip on one of the last inside tacks that one of his jobs was watching main sheet loads? Could be that he stays away from max effort at key times in tacks and gybes (with the other 3 going max effort) and he does his max efforts when everything is stable sail wise? Given the oil reservoir on the boat you could probably have the same average max power across all 4 cyclors but spread the max effort times (assume same on the other side). Would be interesting to look at when the rear cyclors are putting out max effort?
Have seen often that they switch in cycling mode and not all cyclors doing the same effort. Heard that at american magic one cyclor choose the gear for all of them assuming that they had to push at the same time where in the final the high watt numbers changed from time to time between the sailors. looking forward to live data of this as some races were definetly decided by the amount of power available and how fast the sails were trimmed. Thanks mozzy for all your work into these videos. Loving it!
Exactly. What I said later before I read this: On the cyclors doing critical trim adjustments. From what you said it sounds like normally only 1, and maybe for brief periods in manoeuvres 2, of the cyclors will be trimming. And at each tack and gybe that’ll switch to the other side of the boat. On the power data you often see one cyclor around 200W while the others are >400W. So isn’t it the case that the one that has to use his brain is backing off the physical effort a bit? So the two non-sailing cyclors are the primary power source and the two sailing cyclors take turns - one pedals hard while the other trims and pedals gently, and swap at the next tack/gybe.
@@PeterBrand-ky8zw That’s what I’m thinking. Also links into two other points that seem key in this series 1) balancing sails and foil trimming at key points in time and 2) the rumours of auto pilot modes and software updates. Could well be that Freddie is tasked to press button A then wait for load level of X on the mainsheet before pressing button B. With that press being cross linked to foil trimming work through bespoke software? Also links into @MozzySails previous point about the benefits INEOS and LR got from LEQ12 approach earlier on? I do a bit of cycling and I could definitely manage that level of workload when putting out half my peak power (which is a lot less than Freddie’s numbers 😀). EDIT: just had another thought. This approach also links into INEOS towing mast idea. They might have been able to tune their software model between the top/bottom halves of the boat better/earlier with loads coming through the mast and foils at the same time?
Do you think we could ever get interviews with all the teams after the AC has been won, who sit down together and spill some of the beans behind the tech and tactics they implemented for the campaign? I'd love to hear what indepth details they could share and what insights they gathered for the competition. It's almost like having a laugh after the race and share the little secrets that they used.
@matthewungar2138 race craft is only helpful when it's close, when you can get in and mix it up. They did well in race 2. The kiwi boat just seems better. These aren't gains from being able to access the race course, it's a fast boat and a very slick crew. Let's see how Ineos comes out in race 4 after the kiwi aggression today
After 3 races, and looking at the race telemetry and data, Taihoro does seem to be the faster boat, and the faster boat usually wins the Cup. (Unless there is some mechanical failure or catastrophe) watching the post race commentary and debriefs, looks like Ineos Britannia know this too… in regards to the penalty in the race 3 pre-start, Ineos complaining about the penalty is like having 2 cars at an intersection, the Kiwi car has the green light, the Brits car has the red light, both cars know that there are cameras all over the intersection, and they also know there is a traffic cop at the intersection, yet the Brits CHOSE to run the red light, put both cars in danger, and then got all upset when they got caught and were given a ticket… Anyway, good luck to both teams for the remaining races!
Thanks so much for an in-depth comparison. There is only one area in which I disagree with you: to my eye I think Britannia is a beautiful looking boat, though I'm very keen for it to finish second.
it took me about a second to work out the lidar was being used to check the sail shape in practise vs sail making and aerodynamic theory but it took till now to realise the lidar was also checking the live sea state , maybe even the wind speed and direction under the hull to prove end plating options. Im sure the discoveries will continue I just hope the software makes it out into the world so we can all enjoy the benefits.
25:30 Roll control. Is asymmetric flap employment allowed? And/or cross controlled to rudder? Bring the bow through quicker with less rudder drag, back to speed more quickly?
Great insight guys as always, this AC final is either going to be very close or not very close at all given the differences. I really hope that INEOS are on the pace from day one but the Kiwis are seemingly always one step ahead. I anticipate there may be a lot more pre-start, engagement but will have to wait-and-see and not too long.
I wandered if Luna Rosa were liable to fall off the foils when battling before the start. This happened at least once. After that they played it simple in the start box.
Good point. She also nearly fell of the foils in good winds after rounding marks. At least a couple of time Jimmy shouted out he did not know what happened there...
As in AC 36 and now AC37 in the last half of both series final, ETNZ’s confidence and performance were growing significantly. There was no way we were going to lose race 9 given an equal start.
It would appear the data harvesting “unfair advantage” is a little extreme. Understandable that the contract detail was designed to stop a disadvantage to the defender, but quite clearly ETNZ boat has been hacked using challenger boat data. It’s not even close.
LR played percentage game but had their chances dashed by breakdowns and mistakes. Ineos was also very fast in big sea state and that was probably something LR hadn't reconned on. If you are three behind and have been batting around 50%, your chance of winning three in a row is less than 15%. At 6-4, LR had to choose whether to mix up its playbook or count on flawless execution and the rest is history.
Would be nice to also get a longer cut of your discussions 🤩 sometimes it felt like it was cut a bit too short. And as I haven’t delved into the world of foiling sailboats prior to the Barcelona regattas I could certainly do with some translating for dummies when you get into the more technical stuff 🤣 But agree with prior comments, I’m always waiting eagerly for your analysis after each race! 🙏
Thanks again for a great video, excellent insights and analysis as always. Would love to get a bit more insight into the relationship between heel and cant angle and the resultant effect on leeway. I seem to recall Ben and his trimmers having some robust chats about this during the early part of the series? Enjoy Barcelona!
Regarding early/late starts due to software issues, I don't believe the participants are allowing for the dynamic aspect of speed changes in the start (heading up and accelerating) caused by aero drag. If simply air drag increases at the square of wind speed, a lot of drag is coming on the yachts in the final seconds before the start. Nothing like sailing in a traditional yacht.
Rob sorry but painting on Taihoro looking good like a fish fast in water where sea surface breaking light.... ineos only looking like Mercedes german car....
We actually had two twisters hit in the same day. The first one just missed the 800 then the second which was on the news hit the 29er the other side of the club
Good chat lads. Get a beer night organised in BCN! There are plenty of us rattling about the race village looking flor something to do after the racing finishes.
TNZ have apparently changed there sails and have a smaller rudder so i wonder what there logic actually is, as a 🥝 i will be quite fascinated to see what happens
I think LR had faith in their boat being faster which they may have been right at times but not enough. The tight cover kept LR on the back foot and making judgement calls with Ineos successfully managing to keep between them and the mark. Ineos perhaps won the starts but questionable when both boats are where they want to be. Where LR may have gone wrong is being Lee bowed they were not free to give any ground to leeward and couldn’t fully play their hand. It’s gonna be interesting.
I’d love to hear more about the loadings (on rig, sails, controls, hull, everything). You touched on it in another video on LR’s breakages. Ben has said they’re red-lining a lot of the time. Shrek said something too about the importance of easing off the power to avoid breaking the boat and how the whole thing is packed with strain gauges. Surely each team only has access to that data on its own boat? Is the cup going to be lost by the team that breaks their boat by pushing the red lines too hard? Or will it be won by the team that is able to consistently get closest to the breaking strain without hitting it?
Great analysis (and editing) guys. I think your right about NZ chosing a revised optimum wind speed design based on the LVC results - ie low end performance. Time will tell...glhf!
On the cyclors doing critical trim adjustments. From what you said it sounds like normally only 1, and maybe for brief periods in manoeuvres 2, of the cyclors will be trimming. And at each tack and gybe that’ll switch to the other side of the boat. On the power data you often see one cyclor around 200W while the others are >400W. So isn’t it the case that the one that has to use his brain is backing off the physical effort a bit? So the two non-sailing cyclors are the primary power source and the two sailing cyclors take turns - one pedals hard while the other trims and pedals gently, and swap at the next tack/gybe.
I also wonder what impact ETNZ main trimming set up will have? I recall from one of your earlier videos that ETNZ have a setup that’s quite different to everyone else. Is it possible that this enables ETNZ to generate more power in their main to get up on a smaller foil when it’s light?
Yep, defenders have a long time to rest, hence why the challenge has a big hill to climb. I can't wait for AC final it's gonna be epic! #TeamTaihoroLessgo
0-2 well, NZ sail slick, even they do look more lively, they simply are faster. gaining on less wind. Ineis looks very bulky, also creating bigger drag as can be easily seen from the water disturbance from the helicopter shots. … light wins trully againts Ineos
Some points: 1. The challengers accept the defenders advantages because the defender accepts only having one boat. Previously defenders had multiple boats for in-house racing up to cup. 2. There is a video interview with Luna Rossa cyclors where they discuss the advantages of sailor-cyclors particularly in being able to anticipate upcoming loads as well as assisting in manoeuvres. INEOS and TNZ have the best sailor-cyclors. (American Magic had none). 3. INEOS is the only boat of top 4 without in Australian skipper - though they do have Parko and Goobs (a serious speed asset). 4. I believe a big part of the ugliness of INEOS is focused on generating lift so they can get on the foils quicker (a major failing of theirs last cup).
You should consider how fighter jet pilots train.. max effort, max heart rate, doing math, and eye-hand coordination under quite a few gs. There are some people out there that can do it….

Merci à vous et à votre santé!
What I would like to know is why did Luna Rossa have so many structural issues with the sail mechanisms. Was the design/ set up putting higher stresses/forces on these components compared to other boats?
I'd be interested in your analysis of how the weather may affect each team. So to what extent have each team designed for a particular weather conditions (wind and wave), and if the result may be swung by what actually happens with the weather. I'm interested in if INEOS's more bulbous bustle could be an advantage in touch downs when wavy. There was one race where they seemed to use a touch down to stabilise their track when they lost steerage. Do both boats work the same way in this scenario?
Might be like the last cup cycle, Kiwis were a bit rusty but in the end came flying through. I think it will be close and GB have shown they can sail flawlessly. Kiwis mainsheet and new sails could be the marginal difference but they will have to get an even start at best to have a chance Goooooo ETNZ!!
I think taihoro is using dazzle camouflage I it's paint scheme. Thus is going to make it harder and maybe just a split second later for ineis to recognise a direction change. Ots another of those small margins. I think inros missed a trick there but still hope they can bring it home.
With the differences, wouldn't it be great, for the racing to be just as close as the challenger finals. Thats what I am hoping for. Adds another level to the event pressure / drama, whatever you want to call it. Thanks for the analysis, im "normal" speak, for us non-engineers / sailors.

It's really really hard to create the conditions for competitive match racing in a design competition, and I think they've done pretty well here.
Counting down the hours... I think this cup will be amazing viewing, just from a racing/tactical perspective, let alone the speed/technology. I'm a Kiwi and I really want TNZ to win, but if we had to lose it to anyone, seeing the cup held in the UK would be pretty cool. Bring it on!
absolutely! kiwi here, I'm glad the challenger is Ineos which seemingly guarantees at least one more cup cycle in the 75s
Another kiwi here. I’m still pissed at Etnz for taking the cup to Europe so I’m happy for them to lose. That said I’d have preferred them to lose to Luna Rossa.
I’ve been glued to every AC since 1987 but this one has been a bit meh. The fact that racing is from 2-4am hasn’t helped. The racing has gotten closer and better but not a single pass in the LV final?
Totally agree! You guys are brilliant. Your analysis is so good.
@@Alpinefolk4-0 it ain't gonna happen 😂.
One of the unwritten rules of the America's cup is always have a big chunk of pace that you keep in the bag until you reach the final. Linked control software can be very good at hiding the boats true potential.
it seemed to me that in the pre-start Ineos was frequently putting themselves in position to "sweep" in front of Luna Rosa, just like a fan to suck their wind and get them off the foils. They would flick around so fast that it must have significantly disrupted air flow
The ETNZ ability to flatten the windward sail in light airs makes them unbeatable. power over anything else wins. if you look at the cross section of any high lift aeroplane it is a thick wing with flat underside and rounded underside. hence lower pressure created on the upper side equals lift. on ETNZ it means massive power differentials to the d mo.o leech control wire
Re your last point. Freddie let slip on one of the last inside tacks that one of his jobs was watching main sheet loads? Could be that he stays away from max effort at key times in tacks and gybes (with the other 3 going max effort) and he does his max efforts when everything is stable sail wise? Given the oil reservoir on the boat you could probably have the same average max power across all 4 cyclors but spread the max effort times (assume same on the other side). Would be interesting to look at when the rear cyclors are putting out max effort?
We're a bit dependent on when they show the cyclor power graphic, but it's something to look out for
Have seen often that they switch in cycling mode and not all cyclors doing the same effort. Heard that at american magic one cyclor choose the gear for all of them assuming that they had to push at the same time where in the final the high watt numbers changed from time to time between the sailors. looking forward to live data of this as some races were definetly decided by the amount of power available and how fast the sails were trimmed.
Thanks mozzy for all your work into these videos. Loving it!
Exactly. What I said later before I read this:
On the cyclors doing critical trim adjustments. From what you said it sounds like normally only 1, and maybe for brief periods in manoeuvres 2, of the cyclors will be trimming. And at each tack and gybe that’ll switch to the other side of the boat. On the power data you often see one cyclor around 200W while the others are >400W. So isn’t it the case that the one that has to use his brain is backing off the physical effort a bit? So the two non-sailing cyclors are the primary power source and the two sailing cyclors take turns - one pedals hard while the other trims and pedals gently, and swap at the next tack/gybe.
@@PeterBrand-ky8zw That’s what I’m thinking. Also links into two other points that seem key in this series 1) balancing sails and foil trimming at key points in time and 2) the rumours of auto pilot modes and software updates. Could well be that Freddie is tasked to press button A then wait for load level of X on the mainsheet before pressing button B. With that press being cross linked to foil trimming work through bespoke software? Also links into @MozzySails previous point about the benefits INEOS and LR got from LEQ12 approach earlier on? I do a bit of cycling and I could definitely manage that level of workload when putting out half my peak power (which is a lot less than Freddie’s numbers 😀). EDIT: just had another thought. This approach also links into INEOS towing mast idea. They might have been able to tune their software model between the top/bottom halves of the boat better/earlier with loads coming through the mast and foils at the same time?
Do you think we could ever get interviews with all the teams after the AC has been won, who sit down together and spill some of the beans behind the tech and tactics they implemented for the campaign? I'd love to hear what indepth details they could share and what insights they gathered for the competition. It's almost like having a laugh after the race and share the little secrets that they used.
Very excellent thank you all.
MSM - Mozzy Streaming Media. Great coverage from all of you, thanks, from an old IOR fart [who watched the '83 Cup live...]
Great chat - lots of insights. Luckily for me I'm in France so guess where I'm going next week. Should be fun.
I loved it... having a late liquid lunch again, top form - a nice homage to a previous episode where the chaps appeared, post lunch libations
I'd say that the advantages the kiwis are getting within those rules pales in comparison to the growth and race craft that Ineos has gained.
Exactly that. It's a way to mitigate the deficit of not having multiple boats in Defenders series.
Where did all that “gained” race craft experience go? So incredibly disappointing thus far. Just a complete walk over by the Kiwis.
@matthewungar2138 race craft is only helpful when it's close, when you can get in and mix it up. They did well in race 2. The kiwi boat just seems better. These aren't gains from being able to access the race course, it's a fast boat and a very slick crew. Let's see how Ineos comes out in race 4 after the kiwi aggression today
After 3 races, and looking at the race telemetry and data, Taihoro does seem to be the faster boat, and the faster boat usually wins the Cup. (Unless there is some mechanical failure or catastrophe) watching the post race commentary and debriefs, looks like Ineos Britannia know this too… in regards to the penalty in the race 3 pre-start, Ineos complaining about the penalty is like having 2 cars at an intersection, the Kiwi car has the green light, the Brits car has the red light, both cars know that there are cameras all over the intersection, and they also know there is a traffic cop at the intersection, yet the Brits CHOSE to run the red light, put both cars in danger, and then got all upset when they got caught and were given a ticket… Anyway, good luck to both teams for the remaining races!
Thanks for demystifying what is becoming a technology competition 👏👏
You could say that it always has been a technology competition
It’s been a technology competition for 173 years.
Thanks so much for an in-depth comparison. There is only one area in which I disagree with you: to my eye I think Britannia is a beautiful looking boat, though I'm very keen for it to finish second.
Love these War Room/cupboard chats lol
About time the boys got decent handles too🍻
Thanks Mozzy, Tom and Rob.
Incredible data from your youth team. Good luck to Ben.🙂
Totally agree with Rob on the idea that in most racing sports, the biggest gains are made in the slowest sections of racecourse.
it took me about a second to work out the lidar was being used to check the sail shape in practise vs sail making and aerodynamic theory but it took till now to realise the lidar was also checking the live sea state , maybe even the wind speed and direction under the hull to prove end plating options. Im sure the discoveries will continue I just hope the software makes it out into the world so we can all enjoy the benefits.
25:30 Roll control. Is asymmetric flap employment allowed? And/or cross controlled to rudder? Bring the bow through quicker with less rudder drag, back to speed more quickly?
Great insight guys as always, this AC final is either going to be very close or not very close at all given the differences. I really hope that INEOS are on the pace from day one but the Kiwis are seemingly always one step ahead. I anticipate there may be a lot more pre-start, engagement but will have to wait-and-see and not too long.
I wandered if Luna Rosa were liable to fall off the foils when battling before the start. This happened at least once. After that they played it simple in the start box.
Good point. She also nearly fell of the foils in good winds after rounding marks. At least a couple of time Jimmy shouted out he did not know what happened there...
The band is back together 💪
Looking grim guys NZ too good 😁
As in AC 36 and now AC37 in the last half of both series final, ETNZ’s confidence and performance were growing significantly. There was no way we were going to lose race 9 given an equal start.
Beers on love to see it ⛳
The two team I wanted to complete for the AC. Can’t wait.
It would appear the data harvesting “unfair advantage” is a little extreme.
Understandable that the contract detail was designed to stop a disadvantage to the defender, but quite clearly ETNZ boat has been hacked using challenger boat data. It’s not even close.
LR played percentage game but had their chances dashed by breakdowns and mistakes. Ineos was also very fast in big sea state and that was probably something LR hadn't reconned on. If you are three behind and have been batting around 50%, your chance of winning three in a row is less than 15%. At 6-4, LR had to choose whether to mix up its playbook or count on flawless execution and the rest is history.
Any briefing is improved by the guys drinking beer! Doesn’t detract from an excellent discussion.
Would be nice to also get a longer cut of your discussions 🤩 sometimes it felt like it was cut a bit too short.
And as I haven’t delved into the world of foiling sailboats prior to the Barcelona regattas I could certainly do with some translating for dummies when you get into the more technical stuff 🤣
But agree with prior comments, I’m always waiting eagerly for your analysis after each race! 🙏
You didn't predict a result?😊so good
Would love a teardown of the manoeuvring calls on Ineos. By whom and when.
Thanks again for a great video, excellent insights and analysis as always. Would love to get a bit more insight into the relationship between heel and cant angle and the resultant effect on leeway. I seem to recall Ben and his trimmers having some robust chats about this during the early part of the series? Enjoy Barcelona!
I want alternative commentary from you guys!
Regarding early/late starts due to software issues, I don't believe the participants are allowing for the dynamic aspect of speed changes in the start (heading up and accelerating) caused by aero drag. If simply air drag increases at the square of wind speed, a lot of drag is coming on the yachts in the final seconds before the start. Nothing like sailing in a traditional yacht.
Rob sorry but painting on Taihoro looking good like a fish fast in water where sea surface breaking light.... ineos only looking like Mercedes german car....
Great vid .. loved the comparisons.. hope your boat didn’t get mashed in the twister at HISC !
We actually had two twisters hit in the same day. The first one just missed the 800 then the second which was on the news hit the 29er the other side of the club
Love the chat lads,keep them coming.
Would absolutely love it if you did a live stream commentary during the races.
Pleasssseeeee 🙏 🙏
Good chat lads. Get a beer night organised in BCN! There are plenty of us rattling about the race village looking flor something to do after the racing finishes.
Need an unofficial mozzy sails party. Friday or Saturday
TNZ have apparently changed there sails and have a smaller rudder so i wonder what there logic actually is, as a 🥝 i will be quite fascinated to see what happens
7-2 ETNZ is what happened
Hope to catch you in BCN!
Drop me a message on Facebook and hopefully we can see the GBR fans for a drink
Chur chur Mozzy and lad's 🤙
I think LR had faith in their boat being faster which they may have been right at times but not enough. The tight cover kept LR on the back foot and making judgement calls with Ineos successfully managing to keep between them and the mark. Ineos perhaps won the starts but questionable when both boats are where they want to be. Where LR may have gone wrong is being Lee bowed they were not free to give any ground to leeward and couldn’t fully play their hand. It’s gonna be interesting.
I’d love to hear more about the loadings (on rig, sails, controls, hull, everything). You touched on it in another video on LR’s breakages. Ben has said they’re red-lining a lot of the time. Shrek said something too about the importance of easing off the power to avoid breaking the boat and how the whole thing is packed with strain gauges. Surely each team only has access to that data on its own boat?
Is the cup going to be lost by the team that breaks their boat by pushing the red lines too hard? Or will it be won by the team that is able to consistently get closest to the breaking strain without hitting it?
The colour of the boat is a direct connection to Maori culture. Red , Black , Green Blue are our 4 major colors
Need more beers for this poscast😂😂😂😂
Great chat guys " 25:28 we worked it out in 3 seconds so they likely figured it out" brilliant banter.
Great analysis (and editing) guys. I think your right about NZ chosing a revised optimum wind speed design based on the LVC results - ie low end performance. Time will tell...glhf!
'your right'?
I think you meant 'you're (you are) right', right?
would love you delve into the trade offs with what appears to be more oil hungry ETNZ boat vs added hypothetical efficiency
On the cyclors doing critical trim adjustments. From what you said it sounds like normally only 1, and maybe for brief periods in manoeuvres 2, of the cyclors will be trimming. And at each tack and gybe that’ll switch to the other side of the boat. On the power data you often see one cyclor around 200W while the others are >400W.

So the two non-sailing cyclors are the primary power source and the two sailing cyclors take turns - one pedals hard while the other trims and pedals gently, and swap at the next tack/gybe.
I also wonder what impact ETNZ main trimming set up will have? I recall from one of your earlier videos that ETNZ have a setup that’s quite different to everyone else. Is it possible that this enables ETNZ to generate more power in their main to get up on a smaller foil when it’s light?
Yep, defenders have a long time to rest, hence why the challenge has a big hill to climb. I can't wait for AC final it's gonna be epic!
#TeamTaihoroLessgo
Love the format, we need live from Barca now please
Kiwis are ready for the start mate
And finishing first too 😅😅
Sir Peter Blake once said. “Don’t shout until you get across the line”
@@jimhealy4890 The have half a day time zone advantage ;-)
That’s right … go Kiwis !

Love this format! Why do you think Jimmy was not as aggressive in the pre-start as we've come to expect over the years?
What is Taihoro ?
Who you guessing to win? And you cant all pick the same. ETNZ for the win 😊
ETNZ to be smashed. 😂
@@TheEnzedone Well at least your loyal, I can respect that. Its going to be very interesting indeed. 2 very capable boats and teams.
@@TheEnzedoneummm what was that? 😂
Would like to hear your opinion on the defenders more radical rudder change that they have now made
0-2 well, NZ sail slick, even they do look more lively, they simply are faster. gaining on less wind. Ineis looks very bulky, also creating bigger drag as can be easily seen from the water disturbance from the helicopter shots. … light wins trully againts Ineos
Ineos want bigger winds.
Some points:
1. The challengers accept the defenders advantages because the defender accepts only having one boat. Previously defenders had multiple boats for in-house racing up to cup.
2. There is a video interview with Luna Rossa cyclors where they discuss the advantages of sailor-cyclors particularly in being able to anticipate upcoming loads as well as assisting in manoeuvres. INEOS and TNZ have the best sailor-cyclors. (American Magic had none).
3. INEOS is the only boat of top 4 without in Australian skipper - though they do have Parko and Goobs (a serious speed asset).
4. I believe a big part of the ugliness of INEOS is focused on generating lift so they can get on the foils quicker (a major failing of theirs last cup).
Let me grab a beer
You should consider how fighter jet pilots train.. max effort, max heart rate, doing math, and eye-hand coordination under quite a few gs. There are some people out there that can do it….
voila que les sont bien gardé! ce qui n'est pas facile avec des indicateurs et sensors un peu partout. c'est le charme de la régate. premier inconnu c'est la mer avec les vents tourbillonnants proche de la terre, dans une si petite boite de navigation et un parcours trés réducteur des options. Merci pour ces analyses des foils et options coques des deux bateaux. je trouve aussi trés étonnant cette navigation d'avant départ lors des finales pour des régatiers confirmés en match racing! A croire qu'ils ont peur des machines sous leurs pieds et de casser quelque chose qui mettrait fin à cette belle aventure? Je suis comme vous a me demander ce qu'il y a sous le capot de ces belles machines malgré la foule d'informations dont nous disposons pour intox ou pour partage d'info et faire évoluer la série! Merci à vous et à votre santé!
What I would like to know is why did Luna Rossa have so many structural issues with the sail mechanisms. Was the design/ set up putting higher stresses/forces on these components compared to other boats?
I'd be interested in your analysis of how the weather may affect each team. So to what extent have each team designed for a particular weather conditions (wind and wave), and if the result may be swung by what actually happens with the weather. I'm interested in if INEOS's more bulbous bustle could be an advantage in touch downs when wavy. There was one race where they seemed to use a touch down to stabilise their track when they lost steerage. Do both boats work the same way in this scenario?
Does Tom's mum know that they are drinking beer in his bedroom??
shusshhh! don't tell!
Might be like the last cup cycle, Kiwis were a bit rusty but in the end came flying through. I think it will be close and GB have shown they can sail flawlessly. Kiwis mainsheet and new sails could be the marginal difference but they will have to get an even start at best to have a chance
Goooooo ETNZ!!
Mozzy is right:
It's not about SW-update, it's about data like polars updates matching the SW to the conditions.
Swept forward “wings” = less vortices = more lifting capacity. That’s why on gliders.
It’s just more efficient.
I wonder why all the other teams have missed this basic aerodynamic principle?
I think taihoro is using dazzle camouflage I it's paint scheme. Thus is going to make it harder and maybe just a split second later for ineis to recognise a direction change. Ots another of those small margins. I think inros missed a trick there but still hope they can bring it home.
You mean like WWI ship camouflage? Interesting comparison. Never thought of it that way.
With the differences, wouldn't it be great, for the racing to be just as close as the challenger finals. Thats what I am hoping for. Adds another level to the event pressure / drama, whatever you want to call it. Thanks for the analysis, im "normal" speak, for us non-engineers / sailors. Would have loved for it to be in NZ, guess not enough $$$$.
RE NZ $$$ when decisions were being made Covid was a major factor and the health of the countries citizens came first and good on the government of the time...hopefully in 2028 we are back in Auckland...
Hard to say. Really Luna Rossa was predictable at the starts as the channel alluded to. Between those 2 boats the start was critical.
@@ronjenkins7998 And then we all caught Covid anyway. I'm not congratulating the government for the lockdowns, economic turmoil and human rights abuses. Completely mental response, out of all proportion
@@ronjenkins7998 Not arguing, but disagree. Not up to the government to fund or to be held to ransom. Covid a factor, don't think so.
Ineos starts are pretty solid
Yes,against the same old same old that Luna Rossa threw at them. Think the kiwis will be a different kettle of fish
Sail plan's and sail area. Is there any difference as Team New Zealand say they have new sails
Have a great time out in Barcelona! Looking forward to the live stream 😀
