Hire a spy to use stolen information against a competitor. Sounds like they should just add a motor.

Great data analysis! Keep up the good work. Still the best AC news/analysis around.

From sailing in hydrofoil generation, I similarly aim for max cant and then agressively do mainsail trim. The tricky part is balancing leeway and lift when doing a bearaway.

I can hardly wait to see what the AC75s have to bring us to see/not see. This cutting edge sailing is one of the most exciting thing’s going on in technology today. You are helping us lay people almost understand it.

Great job Mossy. Thanks for doing all the work and sharing it with us. It is easy to see your passion for the sport.

Thank you for the time and effort that went into the analysis and video. Really enjoyed improving my understanding of sailing principles (non sailor type) and especially the rather special subtleties of AC sailing

One of your best videos yet. Loving the data analysis. Keep up the good work!

Awesome video. Appreciate the time taken and the fantastic insights

As an aircraft engineer and sailor that explanation is fascinating. Thank you 👏. (Especially for the hard work!)

Fantastic content! Thanks for effort you put in.

Very much appreciate the effort you put in on this one, fascinating!

My pleasure! Although this video was particularly laborious!

I have watched this three times now. An excellent video on many levels. The narrative, the insight, and the graphics combine brilliantly. My 13 year old and I were talking to the Alinghi guys on their open day about the T Foil on their AC37 and how much control they have over the cant and horizontal angle. Haven't Ineos just broken one of their T Foils in testing recently too? Keep up the great work!

Really good findings. Thanks for the effort.

Very interesting analysis. As a non sailor I find your technical explanations and breakdowns very understandable and I always learn something new about these foiling monohulls.

@MozzySails It would be interesting to compare the use of can't angle from the early races to the Cup races. I believe that TNZ only realised what Ineos were doing after they complained about the can't system not being responsive enough. After the software was tweaked TNZ went fully down the rabbit hole. ​​⁠

Another interpretation is that NZ trimmed their board cant more often because they had to, given how unforgiving the T-foil is. Also, my interpretation of Luna Rossa having better performance at low speed is that they probably had slightly bigger foils. Less time on the back side of the drag curve, but too much wetted area for good performance at high speed.

Fantastic analysis! You have outdone yourself today. Fascinating!!!

It took a hell of a lot of time cleaning noise from the data and coming up with filters to focus on straight line... then I discovered some errors in calculation of VMG in the raw data which needed recalculating. It ended up a lot more arduous than I ever expected. There's lots more of interest in the data sets... if don't get told to take this down!

Awesome dude! Absolutely amazing that we got this final closure of the last AC. Keep it up!

Awesome video Mozzy. This method makes me think about the design process behind ETNZ's banana foil (test foil 1) and if this is how they planned to trim it. Also with cyclors back in the cup, the powerplant might be able to produce enough wattage to do that much active main trim. It will be interesting to see which method emerges when the new gen 75's start to race and what the foils look like then. Really appreciate the time put into this one, hope there isn't any backlash for releasing this.

Fascinating as,always Mozzy. Feels like the longest job interview, somebody will hire you surely. Thanks for the hide effort analysing the mountain of data. Andy UK

Great Job going through all that data and excellent explanations of the foils too. Superb video...

I have followed Mozzy sails for some time. This episode is a real GEM. You explained clearly how NZ were able to make progress by their technical advantage they thought through. I hope this feeds into the other teams who are about to finalise their Cup design for manufacturing. Thank you.

Awesome analysis as always. Thanks for putting in so much time and effort. I wonder if the teams are watching this channel to check they haven't missed anything!

Thanks for putting in the effort! Great analysis!!

Thanks for grinding through the anaylsis, and then summarising it so clearly for us. Agree with the comment that it is interesting that other teams had reliablity issues with the cant control systems although TNZ were activating it 10x more often.

Mozzy sails, this deep dive analysis is facinating. Well doneand thanks.

Epic analysis Mozzy. Thanks for all your hard work and presenting it so we can "see under the hood" of what's really going on :)

Excellent analysis. Worth the time - what a progress this channel has made!

Excellent analysis, but why, if ETNZ were working that one design element so hard, were the other teams having reliability problems. I know that some systems work best and most reliably when thrashed, but it seems to me perhaps that the others broke because they didn't make the effort to understand the system beyond it's "up-down" function. Also don't worry about a takedown of the video, I have a suspicion that the majority of your subscribers, like me, are Kiwis and we love this shit. :D

This is a bit late to the party, but I read that ETNZ changed the hydraulic fluid daily. Other teams didn't do this and the fluid degraded or was contaminated with very small amounts of metal.

@grahamlauder2866

5 күн бұрын

@@Kiwi17714 Actually I can see that, but metal filings are not really a problem generally if a system is filtered correctly. Of course you could ask where the filings are coming from which any reliability engineer is going to demand an answer. There is another thought though, pushing oil through filters and coolers suck huge amounts of energy. Both of these things contribute to the longevity of the oil however. So then my question would be, did ETNZ decide to take a small hit on fluid longevity by ignoring cooling and have oil filtering done daily on-shore. That would make more sense, because an onshore filtering rig could filter down 0.5 microns as opposed to onboard maybe 10 microns, and get rid of water and carbon (result of overheated oil). That would save weight (although more reservoir volume helps flatten temp curve) and take restrictions out of the system and increase efficiency. I would definitely go in that direction if I was designing the system, given that the volume of oil used is pretty small relative to conventionally powered hydraulic systems, in fact I would be thinking seriously about using water, not oil, much freer flowing on low pressure systems and mechanically more efficient. .

Thank you Mozzy, amazing video!

This makes the automated control systems even more interesting if foil cant can be controlled in sync with sail trim. Probably a combination of both will be the most efficient.

Looks a lot like the raw telemetry data coming off the boats through the wireless data network and then being distributed to the various data users, if thats how they still do it today. I was in the telecom bunker in 2003, a lot less data points but similar all the same. Was fun checking all the boats data comms boxes at 4am each race day. As an early AC nut was fascinating spotting all the tech, especially TNZ but also spotting the problems. Very well done Mozzie, keep following the breadcrumbs, its a smidgeon of whats really going on but you are doing a fantastic job.

Well done with this analysis very cool! Especially interesting seeing the lack of t foil transition in this cup so far as-well considering what happened last time round.

Absolutely fantastic piece of plausible data detective work, well done Mozzy. Some additional items it would good to get your view on (maybe part 2): 1) Boat handling (aside from grinder effort); 2) Handling in a swell; 3) Take-off predictability and speed, etc.

With all the time and resources you devote to unraveling the array of techniques and technology the AC teams use for their boats, you really should be working for the AC professionally. You have a gift for this kind of stuff. I'm serious.

I can relate to the high, cant angle... tilting the foil to windward and adjusting mast rake, pitch and sale trim is very dynamic on a wind foil. Thank you for the data analysis

FANTASIC! Love the deep dig into the element of the data. Not so relevant for my sailing, but new element to my mind when watching live competition. Thanks a lot for keeping my mind busy )

We really appreciate the hours of work needed to sift through all that data! Thank you. The Kiwis are a canny bunch, and if I was issued a 'one design' package, developed by them, I have to say I would be all over it like rash to see what possible advantage they might have built into the system. I'm not suggesting any software shenanigans, but the simple instruction that the system is basically a deployment mechanism for controlling the foil arms sets the scene nicely for most teams to do just that. Foil tab control and foil development seemed to be quite enough of a challenge for the design gurus.

Great commentary!! Best ever. I really enjoyed that.

Kiwi here, very informative and well done making the effort to unravel some data. ETNZ give nothing away, even to the yachting people here.

Nice piece, nicely done. it was 0-stupid o-clock last cycle but I’m sure in the challenger series commentary was talking how bow down was an advantage! Just as well you got the NZ hospitality in the first ac40 regatta, they might not be so welcoming in Barca lol

I think I mentioned this before it also allows some of the foil to be above the water when not needed for lift or leeway there by reducing drag

Great job!!!👏

I had just one chance to fight against one member of the NZ AC-team in a WC, but he finished behind me. It was just model yachts 10Rater and they did not foil in those times. But it's always the same: Taking advantage of the rules, the physics, the tactics, .... - detecting the aspects making the difference. It is very refreshing to watch what the Aussies did in skiff sailing, NZ did in AC racing, France did in offshore racing. Let's fight them 🙂

This is one of the very best analyses and explanations on what happened in AC 36. Now let all the teams make use of this as far as they did not discover it themselves. Curious to see what will be next!

Fantastic post, ( I even understood some of it ) I am in awe of this guy.

V interesting. It rather makes one want to go back and see the technical specifications for the canting system, and rules associated with it, in order to understand if the challengers were aware that they could operate it as frequently, and in small steps. The impression I as an observer had, was that the canting system only provided 'down' or 'up' instructions - so the revelation here for me was that a team could 'nudge it' up or down, as often as they pleased. Fascinating work - my thanks.

The very first line in the old (AC75 V1) class rule for the foil cant system stated: 26.1 Details of a FCS to control the cant rotation of the foils will be specified in accordance with Rule 33. This system will allow cant to be changed during manoeuvres and to make low-frequency cant setting changes, but the system will not be designed to provide high-frequency cant adjustment. The words about 'low-frequency' changes has been removed from the new rule 😜
