    Vendee Globe 2020 - Virtual Race

    You can, but it's a PITA. You need to use a scheduler / programmation point to schedule the course in the future. Check dashboard, unlock, push a couple minutes, re-lock. Repeat until dashboard confirms the desired course. Not always worthwhile... But when sailing at an angle that's an inflection point in the polars, it'll give some small gains (which can add up if doing it for hours). The nice thing about it is... once you have a programmation out there, you can set a second one and click one degree at a time, and it'll move cleanly by one whole degree at a time. So usually if I bother to do it, it's either because of an inflection point or because I want to set a series of exact xxx.0 programmations. Thanks. I usually don't wake up at night, but I did for that one... woke up at 4:17 AM to adjust the first gybe, which was at something like 4:28. Then went in and out of sleep with my phone beside me, tweaking it every 15-20 minutes for the second and third approaches to the line. Happy to be done with that. I wish I had gotten further north so that I could have single-gybed it. I lost some ground to the boats that did.

    It's fair. Don't worry. TWA 140.0 in 26.6 is 21.95. In 26.2, it's 21.93. Very small gain from incremental wind at fixed TWA. The boats are already going just about as fast as they can. But... 139.0 in 26.2 is 22.10. Heading up a touch gets you some more speed. GAVIB is now sailing 142.8, so I'm not sure what he was sailing exactly when you checked, but it was probably 138.8 or something like that.

    That's one benefit of running without the full pack. You can run without autosails. And in situations like that, it can be beneficial (but you have to be careful). At some point, they turned Autosails on permanently for full pack boats. Can't turn it off. Annoying as hell in certain situations.

    Thanks for the positive feedback. For the most part, I prefer to keep the virtual racing discussion out of the real world threads. I think because while I'm a decent sailor in real life, with some offshore experience, I'm not a pro and don't want to sound like I think I am, just because I happen to be pretty good at the virtual stuff. I'm not seeing dramatic differences between the routings from Herman and Hitch versus Zezo. They generally all seem to be advising routes hugging the ice limit. So rather than posting routings that would be mostly redundant with the excellent work from others, I just occasionally chime in when the virtual routings show me something of particular interest, such as the big patch of light wind that Tripon will have to transition through if he wants to make contact with the front half of the fleet (I'm doubtful, which is a bummer... I want to see him and Beyou both get back into it). I also tend to be looking at long-term strategic elements, which is why back when they were exiting Theta, I was looking 10-14 days ahead at what might be happening when they approach the ice limit. One thing Zezo can't do is help to preserve the boat. I'm not experienced in OpenCPN, Expedition, or the others, so I don't know if those have options to avoid winds in excess of X and waves in excess of Y. If so, then I'd think applying those options would result in routings more like Dalin's and less like Zezo's. PS: Zezo is just a website, not an application. zezo.org. Anyone can use it, and it's pretty straightforward to use. You don't have to be involved with the virtual race at all.

    I've tried clicking really hard and swearing at the computer, but neither works.

    These are the best polars for the virtual boats: http://toxcct.free.fr/polars/ You can also download the polars from there if you want to play with them. Zezo is great for free routing. The virtual boats seem comparable to the 2016 edition's new boats. Top-end speed is 22-23 kts. But can sail at speed in heavy conditions without worries about sea state or breakage (and current also isn't relevant), which evens the odds. The virtual fleet took an early lead, all the way through Theta, but then AT and the other newest-gen foilers sailed away from the virtual fleet after that for a while. The virtual fleet has caught back up now, with AT having his problems and several boats slowing to help with the rescue, mostly by being able to sail near the ice limit in heavy conditions without concern for breakage (beyond Burton's route). The lead pack is currently Southeast of Dalin. Gabart, Peyton, Le Cleach, Lipinski, Riou, and a bunch of other pros are doing it, and many of them are taking it seriously and doing well. Alberto Bona is the leader among "certified" participants.

    Possibly. There are some angles where if you look at the polars, you can incur a series of sailchanges as the wind speed changes. But... VR seems to have a bug with their projected line... I'm not sure exactly what it is. Something like... If you're sailing TWA and a sailchange should happen between 12 and 24 hours into the future, it seems to fail that the sailchange should occur. So it projects a line with your current sail's speed instead of the ideal sail. Meaning the line is just plain wrong (the sailchange will happen). I remember dealing with this at a time when we were sailing toward a light patch and I was still under Heavy Gennaker, flying along. When it got to the light stuff, it seemed like it came to a total stop. Once the light stuff got within 12 hours, though, it seemed to recognize a change to Light Gennaker was going to be required, and it looked fine.

    I'm hoping for the same, but seeing a wall of light wind in his future. He's going to need to make a difficult transition somehow, or he'll slow down to watch the fleet get away again while the boats he has passed catch back up with the new wind.

    Those polars are great for quick reference while using Zezo, but if you want something even better, try this... http://toxcct.free.fr/polars/ (toxcct is a Zezo user who posts in the Zezo forums)

    It'll be interesting to see how they distribute redress. They should give Le Cam a week of redress and a couple cases of wine.

    Gotta wonder if the rescuers will try to get shifts of sleep at some point. Having all of them go straight through the night could result in none of them being mentally sharp enough tomorrow to execute a rescue. But I also can't imagine trying to sleep while knowing someone is lost in a raft. Maybe an hour if you know the others are still actively searching?

    As long as you can stay in the same weather system, you can take some risks and not necessarily lose much in the long run. The killer is if you fall off the back of a system and find yourself bobbling along, waiting for the next system, while the fleet sails away at 20 kts.

    Very fortunate that he had JLC one hour directly in his wake, that it was daylight hours, and that Cape Town isn't all that far away

    Forecast gets light in the SE Atlantic, all the way to the ice line in 3-4 days. Anyone who hasn't made it to CoGH by then will likely see margins to those who made it grow drastically for a while. It'll be important for Roura, Cremer, and Le Diraison to make that transition successfully. Tripon seems unlikely to be able to make it, unless the forecast opens up for him a bit. Seems likely that he'll fly for a couple more days and then run into a dead spot while the fleet gets away. Probably good news, of sorts, for Beyou. By the time he gets there, the wind will probably fill back in, while he will have made big gains on whoever got stuck.

    It's a 70% speed penalty. You'll travel at 30% of your polars until resolved. I'm pretty sure it's the red line. The bars are meant to be a "danger zone". BUT... There were oddities with its implementation in 2016, and it actually hasn't been used (that I recall) since then, so I'm not confident that those oddities have been resolved. Back then, if you were struck by a bug, the "danger zone" was the only explanation you'd get. One thing to be aware of is that the lines are straight compass courses, not great circles. When you navigate with waypoints, you get great circles. The resulting curvature of your course that far south is quite pronounced. If you set two waypoints a few hours apart, traveling East, you'll see a visible curve to the line. That curve will cross the red line if you try to use waypoints to sail close to the limit. So... Don't try to use waypoints along the line if you intend to get anywhere close. This isn't a bug... it's correct. The bug in 2016 was... If your boat was pointed at the limit and then altered course away (such as short-gybing the limit line), if your projected course would have crossed the line within the same 5-minute time cycle, it would tag you as being over the limit even if you never crossed. You'd then be at 30% speed until at least the end of the next 5-minute cycle. It was infuriating if you were in a short-gybing situation. Their answer was that you took too much risk by sailing in the danger zone, not acknowledging it as a bug. I have no idea if they internally noted it and fixed it or not. If anyone gets down there themself and gybes away as shown in winchfodder's image, I'd be curious to know if they incurred this problem. Regarding winchfodder's image... That boat might have been ok. A little more zoom and maybe he didn't cross. Or maybe he did, but only for a minute or two. If the aforementioned bug has been fixed, being at 30% speed for only a minute or two (on top of the 50% speed penalty for the gybe) might go unnoticed by a third party observer.
