Aqua Firma 01 5 Posted January 29, 2021 Share Posted January 29, 2021 You can see in this video from Justin that the boat is not bearing away despite significant rudder input, which finally results with it stalling completely.

From where I stand the boat isn't fast enough (designers to blame), the mainsail choice was wrong (sailmakers) and their way of communication definitely isn't up to standard (TH ??). Also the boat seems very hard to control. Barker is just helming the thing. Even he cannot make a racehorse out of a (USA build)donkey. More embarrassing is that this team is in the top 2 budget wise and has been on the water the longest and they probably go home without a single race win. 4 Quote Link to post Share on other sites

They could be fast enough to shake off Ineos in the finals. Who knows how 2 months off from racing has helped ETNZ.? would be one crazy comeback, and some vocal commentators slating DB here would have some words to swallow.

I think that AM went into the race with the exact setup that they wanted for the conditions and fully expected to do better. The commentators want to criticize the sail, but TH said that in the higher winds they get just as much power with less aero drag. AM has been sailing with it for months and has the data and they have looked very stable using it in before. I think the problems arise from a boat that was damaged much more than we all thought. TH has said that they have had stability problems with the rudder in the training since the relaunch. I know that I didn't tend to see it at first, but they have not been sailing on rails since they put it back on the water. The boat typically gets more stable as they go faster, AM got squirrelly. AM said that the rudder was bent in the crash and you can go back and see pictures of them sticking a Knife in the rudder indicating some de-lamination: Depending upon how they fixed/replaced the rudder, it could cause some weakness that could give less control. The questions from the press said that it was even shakier in Dean's hands then before. TH said that is based upon the speed when you develop some harmonics in the rudder (I do not notice that with the other teams) that causes it to shake. Unfortunately, I do not think that AM has enough time to correct the problem and get competitive with LR. It is a shame, they had a good boat and a good crew. 3 1 Quote Link to post Share on other sites

We see it happen as they hit beam reach during mark roundings and if that number hits high 40's or above, then that appears to be the dangerous cavitation point for rudders. But that's not max speed at all; apart from being bigger and scarier it's no different to the issues you get in skiffs. The bear-away is always the most hazardous part of the operation, and any time you park the boat downwind (for instance by stuffing it into a wave) things get messy. Hence today's tack on the downwind leg because AM didn't have enough speed to gybe safely. Anyone who's sailed skiffs will have abandoned a gybe, at one time or another, because the boat slowed down at the wrong time... I doubt their rudder is cavitating; it's either stalling, ventilating, or a combination of the two, and it's caused by asking more of the rudder than it's able to give. Whether that's not being able to bear away round the windward mark in your dinghy because it's not flat, or because you have a massive sailplan and a tiny rudder, the principles are the same. 2 Quote Link to post Share on other sites

If it is not a manual system but a hydraulic one that feedback wouldn’t exist. Shaking is cavitation/stall issue. The bear away video from Friday, you see the rudder turn quickly to the end stop. That is not helm induced, that is cavitation inducing a flow separation on one side of the rudder. Added cavitation induced drag forcing the rudder to turn toward that side. If the steering was hydraulic control the rudder would not turn, but the added force would bend the blade, or cause some other failure in the rudder, or linkage. The cavitation probably is caused by a poor choice of foil cross section, as in max chord too far from the leading edge. 1 Quote Link to post Share on other sites

Zonker 5,241 Posted January 29, 2021 Share Posted January 29, 2021 1 hour ago, The_Alchemist said: AM said that the rudder was bent in the crash Huh. Maybe they have a metal stock (you do that where minimum diameter more important than minimum weight) with carbon foil. You don't really bend carbon. It either flexes up to the yield point and then goes bang or not. It does not bend and stay bent like a metal. 1 hour ago, The_Alchemist said: The questions from the press said that it was even shakier in Dean's hands then before. TH said that is based upon the speed when you develop some harmonics in the rudder (I do not notice that with the other teams) that causes it to shake. Harmonics from the rudder foil or the inverted T foil I wonder? You'd only get harmonics if there is something creating the forcing - like vortex shedding off the trailing edge. I'd be very surprised if it was cavitation and they were just ignoring it. Whenever I saw Dean holding the wheel in the deathgrip of a teenager on their first drive it heavy traffic, it looked like there was vibration. Quote Link to post Share on other sites

There are plenty of places you dont find white people either. 100 m in the Olympics for a start. Should we force other groups to sail? Should the next 100 ms in the Olympics contain the correct amount of diversity? Cant you see the madness and where it ends? Sailing in boats for racing or leisure is part of my culture. The race has been going on without the correct quotas for 150 years. If you note the Japanese who are a wealthy first world country who on the whole dont sail much. Equality of opportunity is fine but equality of outcome is a fruitless and bloody waste of time. It would be nice to enjoy the sport just for the pure bloody fun. 2 Quote Link to post Share on other sites
**ONTOIT** 109 Posted January 29, 2021 Share Posted January 29, 2021 Feel sad for AM, looked so good during Christmas Cup, but you also have to question the limited opportunity to bed in the repaired boat. The lighter winds today might give them a bit more confidence to sail more aggressively, and they need to find something in the start box and at least keep it close and put some pressure back onto LR. Alas, I can see tears by 6pm NZT as the crew rolls into base and the cameras zoom in on the emotional looks on the team and their supporters faces....all over way to soon! 1 Quote Link to post Share on other sites

Did you not watch the December racing? Anyone who's flown small aircraft will recognise this as buffet; it's what happens when a wing gets close to the stall. It's actually a good feature, because it lets you know you're on the edge. In an aircraft, you can just back off a little, but that's not really an option in a sketchy bear-away. I wouldn't be surprised if they weren't wishing the rudder was a tad larger... 1 Quote Link to post Share on other sites

oatsandbeans 11 Posted January 29, 2021 Share Posted January 29, 2021 2 hours ago, dullers said: ah ok. I think carbon can flex but am not sure about it bending without returning to original shape. I must admit the only carbon on my boat was when the engine was on so i have no real experience of it in a boaty environment. I am pretty sure if it was bent they could have fixed it. I think they have a design issue and wont admit it. No carbon laminates don’t “bend” like that-they behave almost 100%elastically until they fail -normally with a Big Bang. So if you take them to 95% of their ultimate strength and then take the load of they are just return to just like they were before -no bend! 2 Quote Link to post Share on other sites

Yes - his posture has always been hunched and very tense which I don't think is good news for performance when there is no physical outlet for that tension like in a dinghy. He is generally shaking like a shitting whippet, from which I have taken that he either had repeatedly underdressed (unlikely), had early onset alzheimers (unlikely), hadn't had a morning pick me up (unlikley) or was constantly really nervous (maybe). He always looked like that in the early Prada cup, but the boat was a lot more stable in yaw, pitch and heave when flying and seemed to go well esp uprange. It has seemed less so since the crash - I'm inclined to think that is something hardware or software related in foil control rather than the guys. Then last race I noticed that Goodisons hands were also like Muhhamed Ali's on the wheel when handing over, so I think its feeding back from vibrations (1-10Hz region) in the rudder system, which isn't good. Barker probably choppier on the helm today as well which is understandable if the boat is skittish. I don't think it has anythig to do with mainsail unlike some other commentators - they would know if the main is gash and would not use it. I think that from racing cars to luges and skeleton bobs, a lot of efforts are made by engineers to make a racing vehicle place as few demands as possible on the pilot - really good machines are often a bit "twitchy" which can be conflated as "responsive" depending on capability of driver, but in a predicatble progressive way, and don't shake the occupant to pieces. By contrast I couldn't tell if Spithill was ever steering he may as well have hung his arm out the window. By the same token its easy if you aren't under pressure and only sailing the course rather than getting antagonised by another boat. Quote Link to post Share on other sites
erdb 550 Posted January 29, 2021 Share Posted January 29, 2021 Data from yesterday's races show that while AM certainly had control issues, they were actually close to the performance they had in the RR before they capsized. It's LR who leapfrogged them in the meantime. The only major issue that jumps out for AM is that they were pointing the boat all over the place downwind. Their downwind TWA was highly variable (130 - 165 degrees) compared to LR, which had a fairly narrow range between TWA 140 - 158. But on average, AM still pointed a little bit lower (dotted lines): Comparing VMG to the capsize race (wind speed was ~ 1.5 kts higher yesterday) Upwind, RR Race 6 vs Semi final Race 1: AM had better upwind VMG yesterday than in the RR race, but that's expected since the wind was stronger. However, they've clearly lost their advantage in VMG relative to LR. Downwind RR Race 6 vs Semi final Race 1: Downwind, it seems AM is still able to sail with a higher VMG than LR at least some of the time, but due to their control issues, they can't keep that consistently, so the average VMG was a little lower than LR's, while in the RR they had a clear advantage in downwind VMG. In terms of tactics, in Race-1, they were OK, but LR did a better job picking the shifts. In Race-2, they were identical (AM basically followed LR around the course): 6 Quote Link to post Share on other sites
