That move by Burling from 20:00 at the end of the last upwind leg, tacking directly into the path of Oracle, was SUCH a gutsy call. Particularly since he tried the same thing in one of the earlier round-robin races with the same opponent, and it was disastrous. It takes a really cool head to respond in such a supremely well calibrated and confident way to a notoriously dangerous opponent who has just moved 600 metres towards the top mark in the time it took you to move 100. And it's a particularly serious test of composure, given that the race looked completely in the bag for the kiwis up until about thirty seconds prior to the sudden-death challenge from Oracle.
As we all know Spitall is no slouch but this young man from NZ is not going to be intimidated by Spitall - and he has no fear of battling it out with the Americans either
Surprises me that there's almost no talk at all about how the wings (sails) are trimmed. Is that done manually, or is it computerized now? If manually, who on the boat is in charge of that? What is the "twist" on the wing? How much trimming is possible? Is the"camber" always the same angle on either side? Does it differ sailing upwind and downwind? On the 12 meter boats, you heard a ton about the jibs, the trim of the mainsail, the spinnaker sets and shapes ... but not on these? The overriding comments by the announcers are repetitions about the shape of the daggerboards [foils], one curved, one flat, and that's about it. Btw, when the commenter talks about a "shift to the left (or right)" as nearly as I could find out, that means that the source of the wind has shifted left or right. E.g. a right shift would mean that the wind is blowing more from right to left than previously. If you think of the God of the Wind blowing, the god moved more to the right of the course. If the course were set north-south, a right shift would mean the wind blows more towards the west. I don't know if I got that right, there!
Manually, not computerised. Kyle Langford trims the sails for Oracle, and Glenn Ashby for TNZ (he is also the skipper). Blair Tuke flies the NZ boat (controlling the angle of attack of the foils, while pedalling, and with the help of a computerised "suggested angle" output) so he's doing, with more focus and support, something the Oracle helmsman has to do as an extra to helming and skippering. Twist is when the top of the wing has a different angle from the boat's midline than the bottom. The NZ boat had much more aggressive and controllable twist, which helps cope with varying wind shear and also helps modulate the righting moment to keep the boat in stable flight and to permit more aggressive manoeuvres without overloading the foils which risks falling off them.. You basically have the gist on shifts: A left shift, whether you're sailing upwind or down, is when you are looking up the middle of the course (which should be, on average, directly to windward) and the wind is coming from the left of the top mark. Ideally it fluctuates both sides, but with a narrow course it can be hard not to get caught out of phase so that you're perpetually on the wrong tack, if the wind is swinging at about the same period as the time it takes to sail across the course. Putting in extra tacks to get back into phase, in these boats, is too costly because they lose so much ground with each tack.
@@zyunilovesbali216 The point is that there are only two guys on the entire boat who are actually sailors. The rest wouldn't know a sailboat if it came up and bit them in the ass. The commentators are fooling the public, having them believe that the people pedaling a cranking are trimming the sails. The idiots pedaling are even taught to look up at the sails every once in a while to make you believe they are sailing the boat. Even the "helmsman" relies totally on computers to tell him what to do.
@@BEEBEE159 NZ had captive winches as opposed to US had a winch for the main sheet. US were so inefficient. The US wing trimmer was always trimming in and out and Ashby was a lot more settled.
The announcer asked, what was the difference in the boats? I believe the primary difference was that NZL split the duties of steering the boat and keeping the boat on foil. The foiler was able to keep the boat on foil much more efficiently than a part time foiler. This results in less drag and less wasted forward speed. Boats that are porpoise'ing are wasting energy, steady boats are not. That wind energy is applied to forward speed, not porpoise'ing. The difference in cyclors vs grinders is not relevant unless the grinders are unable to keep up. Yes, the cyclors are more efficient, but excess energy, beyond what is needed is irrelevant.
I agree with your first point but I think you dismiss the effect of the cyclors too soon. While grinders might be able to provide sufficient energy to operate the boat in normal conditions, in a tacking or gybing duel the ability to more quickly fill the accumulators becomes a massive weapon. I believe we saw that when Oracle fell off its foils at the start of leg six. Team New Zealand went straight for a gybe after rounding the mark, Oracle followed, they emptied their accumulators, and ran out of energy to maneuver the foils thus dropping off them. The extra power can also be used for making more fine adjustments of the foil and wing (remember the NZ boat has a wing system that it solely driven from stored power unlike the American boat which has a sheet) to increase the boats stability and power. I also heard that the NZ boat had one less accumulator than the others in the fleet in order to lighten the boat. Not to mention the reduced windage of having your guys hunched over and not flailing their arms about in the air. All of these probably only add a fration of a knot of boat speed each but added up and given the fine margins we're talking about its enough to give you an overall speed edge.
@@franzfanz Your point is well taken. The ability to recharge quickly is an advantage, permitting constant use and adjustment. That is undoubtedly correct. As to the reduction in windage, I am not so sure. Bow to stern, with the cyclors nose to tail, is certainly more aerodynamically advantageous than the grinder profile, but is that windage? Windage is considered as the boat profile, which is driven side ways in response to the wind, no? Frankly, the grinders have less of their torsos exposed than the cyclors, who not only expose their entire torso but their thighs as well. I would argue (politely, of course) that the cyclors have less drag but more windage. More of the cyclor is exposed above the cockpit than the grinder, which is a larger profile and therefore, more windage. I think, in any case, that this is a fine point compared to the gross advantage of spit duties, helm and flight. Oracle makes unforced errors, because the helm is overwhelmed.
@@franzfanz ---- The Aussies stow salties below the deck, and by tossing them bits of chicken, use their jaw power to supplement the cycling. Thanks for the info on the accumulators. You do a much better, more informative job than the commenters / announcers.
@@franzfanz I think that's right on the money. The disastrous gybe looked at first like a malfunction, but the fact that they didn't have to fix anything suggests that the 'malfunction' was the result of running out of stored pressure, due (as you say) to having to do several costly manoeuvres in quick succession. So the cyclors may indeed have been a crucial element in them fending off that very dangerous challenge from a very skillful opponent.
@Angelous Bacon So how do you explain the race earlier in the series where the kiwis tried to tack on the face of Oracle coming into the other top gate, and Jimmy baby wiped the floor with them? It's not possible to make a comparison between skill levels without knowing how hard each boat is to sail. My sense is that the kiwis were improving their setup well beyond what the American boat was capable of achieving, (reversing what happened in San Fran) unless Oracle made radical changes which pushed into a design space/territory which made the boat very difficult to fly. The cognitive burden on the helmsman (if this is what happened) could quickly have become unmanageable. I think you would have a hard time finding anyone in Team NZ or Artemis who would agree with your characterising Oracle as anything less than a very skilful and dangerous opponent. But hey, I'm sure you know something the rest of us are denied.
gybe (v.1) "swing from one side to the other," nautical, 1690s, probably from older Dutch gijben, related to German gieben, of uncertain origin. It's a simple difference between UK and US english.

"Dark water means wind speed" It's usually true except in this case it's the ground. Also, I wouldn't mind basic information such as wind direction, speed alone doesn't make much sense, those aren't cars...
Those Aussies on Oracle used the Helicopter flying too low excuse every time they got THEMSELVES into trouble. The Aussies are well known for being bad sportsmen. Fact.
While this type of racing is interesting to watch to me it is not really America's Cup racing! TRUE AC is Single Hulled boats manned by real sailors not ex-Olympic bicycle riders! What they are racing here are catamarans! And i agree there should be a category for catamarans in the AC! But the top style of racing should still be single hull boats! The AC might gain a few fans who like this style of boating but they are going to lose way more fans who enjoy real sailing and not "WaterWorld"!

New Zealand has more boats per capita than most!Great to see kiwis get what they worked so hard for.Kiwis can Fly!!!
I have watched this so many times, I still enjoy the moment when Team USA Oracle made the biggest mistake of the Boat Race 😮😮😮 and I’m a KIWI ❤❤❤
So goooood!
What i cannot believe is that these guys, on both boats, are experiencing G forces!!On sailboats!!Just insane.
thank you!!!!!
i feel like new zealand had a better boat, leg power is so much more powerful than arm power, plus the way they're sitting is more aerodynamic
Wow: what a race!!!
Unpredictable...that was amazing...⛵⛵⛵
The Kiwis are making it look easy over the Aussies...I mean the Americans
😂😂 Spithill the trader
Pit bull Spithill got chewed up and spat out at the start.
Any chance that you'll load highlights of the post conference?
That moment at leg 6 reminders me of fast n the furious, where Paul Walkers character uses his Nos too early 😂
Kiwis: Too soon junior
Love how they say, "that helicopter"

whoop
Good times. Couple of spots in the 2nd upwind NZ was slooow. Not just headed, but stuck in the drink at 10 kn. Looked like a malfunction.
It was smoko break

Why are they pedalling? I heard the helmsman of team USA say "helicopter" when they lost the wind at the final turn?
Indeed, I first thougt they had broken something.
