[@Sprintonthehamsterwheel]

Awesome program Mozzy. I love the AC75... my father hates them. He loved the 12m etc and J class for the traditional technical etc, but the AC’s were a beautiful shape with amazing solutions. American magic looked amazing and ETNZ was a Weapon. I really hope to,see them again

[@raywalker4656]

I'd like to see you guys as part of the live commentary for future AC! And I'd like to see you at the race debriefs asking the teams more intelligent questions than we are currently getting from the press. Great job guys!

[@brianhard1841]

Agreed. I was anticipating some question via zoom at post race conferences. When do we all get to see the foil and sail controls? They've added considerably to understanding amazingly from a vast distance.

[@paulderrick6095]

I was blue in the face after waiting for that one lads. Good job once again. Lord Jim surely must realise he needs your head btwn Ritas flaps. Not sure you'll be able to squeeze past the current helmsmans ego tho. Failing your immediate employment by Team Ineos if you ever make it to Auckland I can console ea of you with a cold bottle of my virtually unknown homebrew in lieu of payment for the most valuable coverage of the 36th AC. There is a huge hole in life now the racing has stopped but I'm grateful for the debriefs. Cheers.

[@brentmags8574]

totally agree about hole Paul mate. Returning back to watching either T20 or ODI cricket... rugby... just doesn't have the exhilarating speed edge, heart palpitations, drama of the pre-start dial ups ra ra ra. Can't wait for AC37...

[@michaelcooney7687]

Too true...we have got withdrawals and wearing out the replays..🤣🤣

[@alienlifeformresearch2280]

Good to see you again Mozzy ! AC sailors loving the 75's is far and away the best endorsement for keeping the class. Especially terrific seeing racers "free-styling " moves and foil cant settings late in the regatta as they became comfortable to dynamically throw these weapons around the course. The AC 75 design concept was a remarkable startup effort ... but only scratched surface of it's racing potential in NZ . Would like to see rules loosened up so boats could be more specifically set up for "wind of the day " and allow racing in broader range of conditions. Perhaps allow 3 foil sets, a couple of rudder/ stabiliser choices and multiple sails with a max size on the main. This would spur further innovation around the bits that matter most for speed and stability. I would forbid "go fast" racing stripes on hulls out of respect for tradition.

[@Silvius.2]

But they want more teams.. then where can afford the money.

[@djholster676]

Like you I thought they were mental going for such a wild concept, but always optimistic that it would work. The reality was beyond my imagination, the racing was extremely tactical, merged with very high level sailing skills and judgement, underpinned by incredible technology. I hope we see much more of the AC75s over the next decade.

Around 27 tonnes to break a foil arm . Great work guys,keep it up . ETNZ magnificent ....got powder dry for the next cup as she did notget to show her legs in a breeze . Showed she was a beast in the light also.

[@knutpohl339]

I'd like to see a bit more action in the prestarts. The upwind starts are a good thing in my book, as is the relatively small box. but I feel we would see more engagement and variable outcome, if the prestart was extended to 5 mins. Additionally, I am not sure the 10' advantage for the port tack entry is really needed any more. It was a safety measure to prevent head-on collisions with the cats, but the maneuvreability of the AC75s should allow for interesting engagements.

[@BruceHoult]

I thought either the box was too big or the prestart time was too short. I don'[t want to see them being able to just go to the far boundary, turn around, and come back to the line to start. boring! They struggled a little to not be early doing that sometimes, with slow modes and S shaped courses, but they were able to do it. I'd like to see a lot more manoeuvres needed to fill the time. Even one minute more with the same size box might be good.

[@solsec]

Yup make it 3 mins

[@OliverBatchelor]

Longer time would might make for some more variation? It kind of seems that with the 2 mins that it was largely quite scripted.

[@davidbrinkman2768]

@@OliverBatchelor With the 2 minutes there was very little that the crew could do. In match racing, the start time is irrelevant as long as you get an advantage over the other boat. In this series, every boat was aiming to start on the start time and without exception they were early. There needs to be a larger area downwind of the start line that would allow tactical sailing and a longer pre-start. It's a shame nobody tried the port start however the team NZ immediate tack for the windward boat had the advantage of getting the starboard second tack. The big problem with the AC75 is the wind shadow from the leading boat making it very difficult to get ahead especially when windspeed was low and boat speed in the 20+knots.

[@J.Smith-rc6wh]

we took our 19 foot boat out to watch the racing and had a great time, could see it all well, and was really impressed by the boats as they went by, even when they were just being towed at 50 km's out to the course by the chase boat, so from a spectator on the course this was the best boats yet, remember the first ac in auckland was five hours out into the hauraki gulf, way beyond the reach of most boats. People could watch really well from beaches and the shore, particularly through telephoto lenses. watching from the water was so different from on TV, and really fun, and the whole event was really a big deal in the host city, whereas with other boats this was not the case, a huge success, a fun event and we are going again

[@TheBimbler]

Thanks to all at Mozzy Sails for your excellent videos throughout the cup. Superb, insightful and essential viewing.

[@barfootSmitty]

Rob, with regards to AC75 vrs AC50; I was down at the village and was struck by the frailty of the AC50 nailed up on the wall. Looked like a model airplane, solarfilm fairings over tiny ribs, bike seats sitting above the coamings, both sides held together with flying and ground wires. On the other hand the AC75 looked like a solid bit of kit. No wonder the sailors feel so much safer in the 75. Mozzy, great series, come back to SA, ignore the under bridge dwellers.

AC should represent the pinnacle of inshore racing technology - 100% agree. AC75 was that and more. Can't wait to hear from the lads again.

[@jfwarp]

I'll add my voice to the crowd on favor of higher minimum wind speed limit, and more complex (or larger) courses. The Freemantle AC was exhilarating even if it was sailed in pregnant guppies.

[@brucegibson5425]

Firstly, the weather here in Auckland has been very light conditions. So very little chance of seeing any of the boats stretch their legs. Secondly, I agree with all of your comments, we need someone to explain the need of the foil box limitations & sail area etc. These can be free design as I'm concerned . Looking forward as always to the next installment Mozzy.

[@rodneypaterson7234]

Great debrief guys,and like the idea of freeing up the rules and allowing creativity to have a place!

[@Dylanyo75]

Hi Mozzy, thx for your new vid. I missed them even if just few days have passed since AC ended. What I would change for next AC? Here is my wishlist: - more challengers (and no anti - Jimmy Spithill or anti - Dean Barker rules if possible...). - a bit longer races (40' races with mid wind would be good). - tighter races. Idk how to perform this aspect, but I would like open water races on wider spaces, where it's possible more distance between boats so that the advantage gained by one team would be not so secure till the end. - adding fleet races on open water at least in the ACWS. - improvements of AC75 with light wind.

[@paulchristian8261]

I think the nationality rule is a premptive move to stop other challengers buying out ETNZ team members. Unfortunately Dean and Jimmy are collateral damage to that. I agree that 40 min races would be good.

[@johnshealy326]

Thank you Mozzy, Tom and Rob for your continued brilliant insights regarding the AC75's. Let's hope the Cup holders listen to some of the suggestions you guys talked about. Well done again.

[@billpitman4350]

Great discussion - well done thanks.

[@Niels4354]

Nice sweater and favourite channel for proper AC75 / America's Cup info!!! Unlike for example the live commentators during the Cup despite all their sailing medals did not add any value or insight during the sailing.

[@maxhugen]

"Do we want to see them go faster next time?" Yep! For an AC75 v2, I'd like to see not only the option of different foils per race, but also a shorter mast/smaller sail plan combo for stronger winds. SailGP has already done this with their wingsails. With possibly faster speeds, we may see some brilliant designer solve the problem of a foil that performs in both sub- and super-cavitating modes.

[@rbcg105]

With the wing it's cheaper to make it modular. With sails I'd be a bit worried that multiple masts leads to multiple sails and the costs go ballistic. Maybe a removable mast stump and reefs in the main? Twin skins would reef pretty neatly as the sail could be tucked inside its self

[@maxhugen]

@@rbcg105 I was only thinking of one extra mast and with a high wind sail set, but you're probably right, more expensive than the wingsail.

[@rbcg105]

@@maxhugen I do think there would be potential for a mast stump which is removable. Maybe at the top or maybe at the bottom. And combined with a reef it would work without much extra cost

[@maxhugen]

@@rbcg105 Maybe. But considering the extra complexity... hydraulics that also run up the mast, still need extra set of rigging, a reefing mainsail would be a major change...

[@MrGritteeth]

Thank you Rob, Tom and Mozzy Sails for a thorough debrief. I agree with suggestions made especially the two type of foils and removing the bowsprit. The sails were what made this cup exciting. Crews must be given choices on the day for a make or break contest. Let’s hope for more teams next time around. See you next time. I will maintain my subscription.

[@MckayGeoff]

Always enjoy your videos but I think all this talk about making it cheaper so more challengers can take part is a joke. Ok, there maybe more challengers in such a case but the fact remains that there will always be only a small number of them that have a realistic chance of winning. I think even with the small number of challengers they could have had more racing. Plus the covid knocked out two of the world series regattas. Also I think huge kudos to Team NZ for coming up with the AC75s - which despite the doubters is the real winner and shows just how good the Team NZ designers are!

[@michaelhowell8412]

Dalton had talked about making it cheaper would be great because you'd get more teams involved but also said he didn't want it to become a beach regatta

[@Nobilangelo]

The box rule for the foils is needed so that the separation between boats can be safe. If they stuck out varying distances on different boats you run the risk of nasty things happening under water. Like collisions...

[@OliverBatchelor]

Could be simpler though, like only extending X distance outward from the foil arm.

[@MrVaticanRag]

Yes- Change the fixed rule on one foil only for series - so can swap to any foil already submitted for accepted conformance.

[@iwal1645]

The AC75 class certainly peeked my interest, i was looking for what boats look like before this new AC75 class, mind already blown by the keel changes.

[@zxvjy]

I am speaking coming from a club sailing background and now sadly a spectator. Match racing as we have come to know it is dead with these boats. They are too big and fast to risk any close manouvers. For me the lack of on board action is a major concern. With most of the crew involved in purely powering up hydraulic systems all seems very sedate. Most sail trimming is so minute as to be invisible except post race when you guys disect it. I do miss spinnaker work, sails actually being trimmed in and out and close on the water racing.

[@georgeeddy594]

I agree 100 pct with Barry’s comments here. The speed of the boats is amazing, everything else was a disappointment.

[@dboy5273]

yes been waiting on this thanks guys

[@peterrobotham1214]

Great analysis and review as ever boys. I wanted the camera to pan out and find Rob having a pedicure, that is what you call laid back !

[@morgananderson9647]

This analysis team has been so good through the entire event! Thanks for the great coverage!!! I hope you'll continue to provide this type of coverage for other classes of racing too. As far as designs, I guess I'd like to see a Keel based foils on this class. I think the technology is now available to make it happen. I believe it would inspire even more close boat on boat combat. It would also encourage the secrecy element as the Keels could be hidden from each other until the racing began, then require the teams display their full hull to the public as they are placed in the water. I'm eagerly awaiting your discussions on the race format. Best regards, Mo-

[@michaelbradley5722]

I'm not sure if two sets of measured foils is a good idea. With more than one race per day will you be stuck with the same foil for all races on that day? Quick change foils between races out on the water? I suspect they are more motivated to limit costs rather than increase complexity and costs. One thing guaranteed is that whatever ETNZ can afford to spend the others will still just find complicated ways (designs) to spend more and then complain about the costs.

[@leuvenisaplace]

A day after initial viewing of the analysis here, I'm increasingly mindful of the idea that I enjoy the America's Cup despite it being a type of pissing-match for Billionaires. Team NZ are an exception (though there are some others too) and that they seem to be successful, adds to my appreciation. There are plenty of one-design(-ish) classes that though are good racing and excellent for development of skills, they lack the element of madness that the America's Cup seems more routinely a venue for. The America's Cup whether we like it or not, it is no level playing field and I think sailing needs a class that where the class and the rules are rarely allowed to settle for long.

[@MrARH]

Areas that will provide opportunities improve dramatically 1. AC75 Design evolution - really just on at beginning of multiple design pathway and solving the trade-offs 2. AC Sailing skills - @MozzySails discussion of evolution of sailing on ETNZ for example - roll-tacking, 1-foil JK, 2 helmsman or not 3. Race tactics - we have had how many races (30?) - still writing the tactics at 50knts, while foiling, with huge wind-shadows, - it will be a whole new playbook 4. Options for pre-start 2min, 5 10? Course I cant wait

[@zaphodify]

I heard Francesco Bruni in an interview asking for a lower take off wind speed limit for the new AC 75 boats. (Race 9 must still be a nightmare...). This would mean lighter new generation boats IMHO and probably new foils design. That said I would be very careful about the components liberalization. A monotype would not fit the purpose of an AC class (but it would bring out the skills of the crews), while an excess in planning freedom would dramatically increase both costs and risks in building boring races (F1 like) in which the faster boat always wins no matter the helmsman is a skilled sailor or a "sunday boater" and so reduce the number of participants. A fair compromise must be found between the two extremes.

[@jfwarp]

Raising the lower wind limit would accomplish the same thing. More wind!

[@andrewpease3688]

British tradition, slow boat, wealthy sailors

[@Kiwigd]

Mozzie, thanks mate for the great chatter.

[@BenCJF]

Some of the AC75s are the most achingly beautiful boats raced of recent years (LR example in point), coupled with being the real sailing equivalent of F1, they still managed to produced epic regattas, and exciting to watch regardless of conditions.

[@davoforrest5]

[@brignorth9662]

So happy I found this channel two months ago -- absolutely my "go-to" for Cup. Listening to a bunch of engineers talking complex boats is a hoot to this decidedly non-engineering type. And Rob, in Texas we say "Pioneers get arrows, settlers get land." The four teams of this Cup definitely did the heavy lifting to get this class sorted. Looking forward to the next video.

[@karelvandesande9848]

Thanks so much for the insights.

[@J.Smith-rc6wh]

more foil choices would be cool definitely, also would say the low wind races were totally cool, the coming off the foils add edge to the event, the race NZ came from behind to win was really exciting

[@artistglyn]

People only usually complain about rules when they are the ones who didn't think of the other guys interpretation. I seem to remember a certain Dennis Conner complaining bitterly about New Zealand making a GRP 12 meter back in 87. Said it was impossible to make a 12 mtr in GRP and be within the rules. Next cup, they were all GRP. Rules are just a starting point for innovation ! Good work guys, and now Ainslie is COR there will be no excuses !

[@johnmartin7158]

As usual a well written post from you Glyn. Shall be interesting to see what eventuates.

[@artistglyn]

Thanks John. I try and be relevant !

[@Supasarge]

Imagine the outcry if they allowed Tour de France teams to use any form of e-bikes?! Batteries for operating below deck mechatronics has been THE necessary evil in the inaugural version of this new class imho. It got us to where we are (which is great) but high on my bucket list for AC37 would be all equipment must be operated from power sourced from the crew and/ or renewable energy generated during the race (no stored energy taken onboard).

[@MozzySails]

I really like this idea, plus it's got great trickle down potential. A possible next step could be to have just enough stored energy to the the bare minimum foil drops and raises, and above that must come from grinders, solar, or hydro rather than stored chemical energy.

[@Supasarge]

@@MozzySails Indeed. Given the hydro and aero forces endured (above and below decks) you would think the AC class might be an ideal placement for innovating and showcasing effective systems to capture and harness ‘lost’ or ‘wasted’ energy, such as Kinetic Energy Recovery Systems (KERS) for the marine sector.

[@jamesaron1967]

Well, the analogy to the TDF allowing e-bikes is not tantamount. E-bikes use batteries to power motors for propulsion, and would grant an unfair advantage to racers unless every team was allowed a one design e-assist. However, that doesn't make sense in a sport that uses muscle power for propulsion. Bikes in pro cycling have been employing electronic shifting systems for over a decade now. These transmissions are more equivalent to the electrical systems on the AC75, which still relies solely on wind power for propulsion.

[@trathje424]

Thank you , looking forward to more AC content!!👍👍

[@SuperReasonable]

I think this class is brilliant and should be retained with a few tweaks. The boats stood up without major failure, they were very fast and handled like small, very fast dinghies making them ideal for match racing. They also have features that can filter down to normal sailing, particularly the foils, foil arms, boomless mainsails and twin skin sails. The cats were fun, but the fact they looked the same, didn’t go upwind on a good VMG, had a wing sail that can never be used outside of this sort of racing and they didn’t handle like the AC 75 made them redundant for me. We now need to see a certain restricted release of IP from team NZ to encourage new teams to join the AC club. We also need to see a smaller AC75, maybe 50’ that's available only to AC teams to race around the globe the 4 years between the actual AC races. The major revamp must come with new rules, new penalties new courses and new pre start discipline. We must have races that are not decided in the main, purely on the pre-start.

[@space1nvaders185]

It will be interesting to see future foil or foil skin designs overcome cavitation challenges which could see next gen AC75 turn smoother and foil faster. We could see 60kn speeds. Well done Team NZ. You had top sailors who were engineers and young engineers who sailed, both men & women.

[@tonysu8860]

IMO... - TECHNOLOGY Everyone loves pushing the limits, exploring what hasn't been done before. But it should be recognized that this becomes possibly the single determining factor who wins. If one boat has a decided technological advantage over the others, there is practically nothing any can compete with the leader. - SPEED Of course speed is what grows interest and the audience. Everyone wants to know who's got it more than the others. Hardly anyone is interested in the fastest turtle. And yet... the faster the boats are, it should be recognized that it's harder to be competitive with an even slightly inferior boat. Match tactics won't work if these large boats are flying up and down the course with each leg only 15 minutes or less. So, make the course bigger? Maybe, it would have to be looked at whether competitiveness is worsened or bettered. - LOW WINDS Maybe allow an increase in sail area? At least with more changing conditions the race is returned to seamanship and less only a technological race. Bottom line is that the current direction of the AC class is good to generate interest, particularly from the casual non-sailing public but I lament the fact that the humans are less involved in the result in all the years up to and including the 12 meter class. It was because the 12 meter class forced you to push this enormous, bulky object through the water that the human effect was much more relevant and match racing skills and seamanship were more important determining the result.

[@djholster676]

The America's Cup started out as a deciding contest to see who had the fastest boat. Let's leave it like that.

[@RichMac46]

The AC is a magic yacht, but the light wind problem need to be solved. The class rule prohibited any form of tunnel hull, NZ was nearly a tri-hull, but with a full width transom, to comply with the rules. They should allow tunnel hulls, but still with the same outside shape, so they look great. This would reduce drag from the massive wetted area when they are in the water, so they could accelerate quicker to get on the foils. Also, maybe allow the use of centreboards, so they could sail really efficiently in light weather with both main foils up. If you make the boat more efficient at getting onto the foils, you can reduce both foil and sail area, increasing efficiency at high speed.

[@jamesaron1967]

I was thinking of ways they could sail in light winds with both foils up but they would need something like a centerboard as you say, which can then be lifted once flying. It adds complexity to the design though, and this class doesn't need more complexity. I'm sure they could come up with something rudimentary but sufficient enough for light wind days.

[@bmpowellicio]

Am I the only one who would like to see all the boats racing together, at least once? A fleet race could be a Ben-Hur like spectacle.

[@itabs-auckland6547]

Great too see you back Nate missed your vids

Great wrap up guys... Interesting thoughts on b improving the class.

[@brendonlagemaat3361]

A lot of the "Sailing Innovation" in New-Zealand had its (roots) origins in the Wednesday Evening Sailing run midweek by the RNZYS and the Richmond Yacht Clubs in Auckland from the early 1980's , in fact from 1980 , there was a tremendous amount of innovation in Sail making , Masts and different Boat Designs . The Races were and still are a quick 1 hour 30 minute race (approx) where for some Racers Line Honours was paramount , even though it was a Handicap Race . NZ does have a big sailing culture , especially in Auckland .

[@Nobilangelo]

The bowsprits are needed for the cameras and the other bits they have mounted on them, not just for code zeroes.

[@laser3322]

They definitely need the bowsprits. Where else would they put those rear facing cameras that give us nice views of the boat getting onto it's foils? :-)

[@rupertmiller4718]

A personal opinion of course but I thought these were so much better to watch than the cats. Having seen the cats close up in Cowes I thought they became quite boring to watch. One race was quite enough and I thought the AC itself was equally so so to watch. The AC 75 looked so much more technical as well as more dynamic to watch. I thought this was the best since Freemantle, which shows my age!

[@MrVaticanRag]

How about Figure 8 races around Browns Island & Motuihi island - fore-runner for round Wight island in 2027?

[@ptewilks2634]

Great show, yes 5 mins starts maybe start line could be mid course, maybe reaching starts, maybe midcourse marker I have had to have therapy just loved this am cup want more now

[@djholster676]

If the specified wind range goes down to 5kn, one or more teams will build a boat capable of foiling at 5Kn. The idea of optional foils (maybe from a limited number of sets(2 or3)) would still allow racing throughout the range.

[@nb9361]

Thanks for producing the most informative channel on AC 'boats'? on KZbin. Well done, keep it up. RANT WARNING…………….. As you know, a sailing yacht has a displacement hull which contributes to the power & performance of the yacht when combined with the keel, rudder & sails. The design process is complex, challenging & rewarding, providing many subtly different design solutions for any given rule. With respect to the AC75's, I wonder what the teams have left to design. The legs & hydraulic canting gear are supplied, the hull just keeps the whole thing afloat & has no performance contribution what-so-ever. If you beach it you're screwed. The sails are designed & supplied by North, & the mast is an aero-foil which hardly challenges today’s powerful computers & complex software. So really, all we have left to sort out are the wings. INEOS, you had one job. According to our Shirl, the first wing attempt had protruding rivets. Seriously, PROTRUDING RIVETS, I can still hear the disgust in her voice when she commented on it. Sir needs to sack the design team, or Sir will never win the Americas Cup. End of. AC75's require relatively small design input & do not reflect in any way, shape or form the race yachts that are raced by club sailors on weekends & regattas around the world. As for sailing them, it takes 6 gorillas, a computer & 1 dinghy sailor to spot the shifts. No sail changes & upwind all the way. BORING. I think this is a great pity because pretty much all sports have, at their top level, the same game, played to the same rules, with the same(ish) equipment as is used at grass roots level. Players & racers alike can identify with the sport that is played by the top & bottom ranks. AC75's are a novelty, they have nothing in common with grass roots yacht racing. They are designed to appeal to the ignorant masses who think that if a 'boat' goes fast it must be good. They will pay to watch it & this, in theory, should attract teams (3 challengers, wow!) & sponsorship money, (TNZ are now broke). FAIL. By all means, have a challenge next year, that’s one cycle, another one 3 months later, that’s the second cycle, both between NZ & UK. Charge some unsuspecting port an absolute fortune to host it, twice. Give the money to to TNZ providing they crack-on with an extreme displacement / planing rule with upwind / downwind sails in 4 years’ time in boats that are barely sailable. EXCITING. AC75's are not sailing boats. They are Wind Assisted Nautical Kraft. The sooner they go the better. Here end'th the rant. Amen.

[@TheUltimateWriterNZ]

Nice to see the boys again 👌

[@paulhi3561]

All well thought out intelligent comments, informative. Pre start is a bit static, maybe 4 5 min prestart and no tow in help . I would love shifty conditions

[@zlm001]

Do you think more technical and engineering information will come out regarding the AC75 now that the cup is over? Or will teams still keep that confidential?

[@maxhugen]

Unfortunately, we probably won't get much more info than we already have. Not much was really divulged from AC35 either.

[@WhatAboutTheBee]

In consideration of two more cycles of this class, NO, the teams will not divulge their secrets!

[@zdikbiodr7341]

"Sadly the 36th America's Cup is over." How true. For days I kept waking up at 4 a.m. with nothing to do... I really wanted the Italians or the Brits to win, to watch the next AC at a more reasonable time.

[@Chris.Davies]

I can't wait to see AC racing at 120km/h boat-speeds. That will mean closing speeds of up to 200km/h! This was just the very first generation of foiling mono-hulls, and the following generations are going to absolutely blow our minds. These days when I see any kind of yacht at all, I expect it to pop-up and start flying! Yes, we absolutely DO want to see them go faster next time. I'm not a sailor of any kind, and I'm not interested in sailing at all - EXCEPT the foiling monohulls. If AC had been in Catamarans again, I would not have been interested in the cup, or the racing, and wouldn't have been at all psyched to watch it. BUT, we had amazing boats, and I couldn't stop watching. THAT should tell you everything you need to know about these boats, and this class.

[@paulgush]

Good video an discussion. Some other questions I would pose: 1. Ballasted foiler? Who let Doug Lord design the class rule? Do we want yachts that need to be powered? High voltage powered yachts? 2. Are the boats too complicated, expensive, and unreliable? 3. What was wrong with cyclors? And cats for that matter. Both made for a much more efficient concept

[@jamesaron1967]

I can only reply to your third point: cyclors were banned because they didn't represent a connection to sailing but from another sport. They wanted sailors not cyclists in the AC. As to the cats, if they were that much more efficient why did we see higher speeds with the AC75? I'm not against cats, actually, I usually prefer multi-hulls but I also like innovation and the AC75 class is simply incredible. I can't wait for the next generation provided they don't dumb it down too far in an attempt to reduce costs.

[@paulgush]

@@jamesaron1967 I meant energy efficiency. The crew could raise and drop the unballasted cat foils with muscle power alone, whereas the AC75s are battery powered below the waterline. Also, there is a long tradition of grinders coming from other sports. Team NZ's Rob Waddell was an Olympic rower

[@jamesaron1967]

@@paulgush If it was up to me I'd allow the cyclors back. I'm only stating the reason for the AC ruling. Regarding the foil system vis a vis the current and last gen classes, the foil system is too complex and probably too heavy for muscle power alone to achieve the same degree of performance in the AC75. I'm sure it was necessary to have it function this way.

[@paulgush]

@@jamesaron1967 well, it comes down to the decisions they made. The less beam you have, as you go to monohull, the more movable ballast you need for righting moment. The movable ballast, the more power you need. So the rule requires ballasted foils, which was also supposed to make the boats self righting. But that didn't work. Lots of reasons to go back to cats...

[@67daltonknox]

This was some of the most exciting America's Cup racing in my 8 decades on the planet. The sight of boats weighing 6+ tons match racing at speeds up to 50 knots was to say the least exhilarating. Finding skippers to handle them may be more of a problem as the domination of good starts demonstrated.

[@M77MK2]

I don't think it's realistic to expect 10 teams in the America's Cup. It has always been a high cost sport, and I think that history is part of what makes it so special. It needs to be really difficult to win it for it to retain its mystique.

[@rbcg105]

Pretty sure there were 10 teams in 03 and 07 when it was in Valencia.

[@VISTLER]

Much more interesting than I expected it to be! 😉

[@stephendacre]

North sails paid 40 mil to have sails in this cup How much did they make again ?

[@rbcg105]

Is that what the sponsorship agreement was? Interesting. They obviously feel they will get a return on that. Even more reason to up the sail limit to recoup some of the costs.

[@ScottSummerill]

I was missing you BIG. Don’t go away.

[@mis100tubos]

Waiting for the next video!!! Good job 💪💪💪

[@rossatonic572]

Doubling the subs in the time i have been watching. Bravo sir!

[@Tom--Ace]

I'd love to get a foiling bluewater cruiser for the family, that would be amazing! Though I realise the design challenges are myriad, the AC75 was a littoral 75 foot 7 ton vessel, even a 45 foot Beneteau cruiser weighs twice as much. 20+ knot sustained ocean crossings on the future horizon?

[@ProBioMech]

Rob looks like he was really relaxed in this episode.

[@anmihovil]

Probably he's over disappointing race result. He predicted 7 - 0 and it was 7 - 3.

[@brianmawdsley1216]

Just watched the changes for the new season of F1. Diminishing returns within a complex rule structure makes a poor spectator sport. I would look to F1 for the route not to take. Loved the boats this year, a total achievement to design, build and sail and so beautiful. And so sublty representative of the nations involved. Your channel really enriched my enjoyment, thanks.

[@_JustinCider_]

Changes I'd love to see: 1: 2 foil sets, pick which one you want to use on the day of the race. Hell, make it the same as for the jibs - if a team can figure out how to change foils out on the water 10 minutes before the start why not let them? It just makes sense to include the foils in the low wind & high wind setups. Also open up the design rules. They played it safe this time around, now let the engineering geeks loose with more open design restrictions. 2: These are boats that are pushing 100km/hr and they're racing around in a tight, tiny little course for what 20 minutes? It's like putting formula one cars on a go kart track. Let them open up, get weird with the course layouts. These things can sail in pretty much any direction relative to the wind and can turn 360 degrees like they're on rails. Set the course to sail around Rangitoto and throw a chicane in the downwind leg. 3: Increase the lower wind limit. With one glaring exception the most exciting portions of the races in this regatta was when one of the boats on the water wasn't going anywhere. Surely that's not right. Race 7 showed what could be, and I believe had we seen some races at the upper end of the wind range it would have been even better. 4: I'm not convinced on the value of retaining the grinders. While it does keep some tenuous link to traditional sailing for the purists, increasing the capacity of stored power on board and keeping only say 2 grinders for trimming and such seems more logical. Grinders on these boats are just carbohydrate powered motors supplying hydraulic pressure.

[@douglasashby4349]

AC needs to be the Pinacle of inshore racing. Full stop. We need to keep pushing the boundaries!

[@WilliamLHart]

Design Suggestion: Only one foil allowed - Team decides what side of the boat. Race is then both displacement and foiling increasing the seamanship quotient significantly.

[@Rimmin1]

I'd like to see the 270⁰ penalty return with the ability to stack/offset. Most teams proved their ability to complete 360⁰ on the foil during practice. I also wouldnt mind the return of the 4 minute entry.

[@turvyjj9232]

Since many people like AC75 and others still prefer traditional monohulls, make a combination of the two, allow foils only for one tack, and monohull the other; so you combine the two ways of sailing. By the way, I love AC75s, they have taken sailing to the new frontier. Just rise up the low wind force level.

[@741662027]

I'd like more discussion about the goals of the Cup. Rob mentioned the benefits to the marine industry, for example. The same way that F1 technology comes down to our daily drivers, Cup technology should improve all boats. The double-skinned main seems among the affordable improvements (except for the pivoting mast). Another goal should be to make the racing exciting, with more ability to pass. Going to a lower wind range is not a benefit: splashdowns mean "game over", which is no fun. It's also exciting to see beautifully executed boat-handling, both at the helm (longer pre-starts!) and sail handling. With no dramatic chute launches and takedowns, it looks more like a bicycle race than anything else! The stern cameras are great, but there's no visible movement of controls on the boat except the wheel, and not much of that. The integrated control systems seem like an area that will trickle down to benefit foiling day sailers, and would improve safety to help us learn to foil.

[@mrdodge4529]

keep them coming

[@malcolmrae6308]

Loved the actual boats but I think a combination of a compressed race calender and course selection limited the overall competition. I understand that COVID played a large part in this and a longer race calender risked more cancellations but really only the 1 course provided interesting racing after the pre-start and more emphasis should have been put into racing on that course.

[@11calman]

Mozzy Sails, Well done mate. I would say, that with the millions of dollars involved with these boats & England is a Challenger, You will have the Racing in your part of the world (Maybe Cowes) (Isle of White). More central to Spain, Britain, France, Germany, Italy, USA, Canada
