Bermuda Challenge

Looks like there will be a new race starting tomorrow at 1600z. Ft Lauderdale to Hamilton.

Interesting, as those are sort of my home waters. But, would be a lot more interesting if the game included currents. How you handle the Gulf Stream is the trick to that route.

Hi Cvetan,

Can zezo support this race, starting in 10 hours?

sur la page d'accueil, il faut faire "F5" et la mise à jour fait apparaître la course "Bermuda".

Race is underway.
Dashboard shows impossible positions for some boats - boats have travelled up to 7-8km (5min after the start), but the position timestamps are in the past (eg, 2020-10-21 16:26Z)
Looks like the race was running yesterday from 16:00Z - 16:30Z

When using the VR dashboard extension (chrome), I do not have anymore "following" competitors in the list; nobody is there. So I use Zezo routing entering manually my position without the extension.

New user of Zezo... It takes me completely E/SE and then North East tomorrow.
Seems the pack of sailors is going directly North East... we'll see. For now I'm almost last... worst ranking ever (18000 out of 19000). Waiting for "la remontada" :-)
Post by iconPost by zezo | 2020-10-23 | 20:01:21
There is the possibility of a low pressure system W of Bermuda. It rotates CCW and cuts off the straight track, favoring approach from South.

Those things are somehow unreliable when they form. Some of them turn into hurricanes and some die off, so it may not appear right there and then, in which case we lose.

But then the North Atlantic is probably the place with best marine forecast it the world, so it will probably come to the date. I've seen 7-day runs from NY to UK materialize with one hour difference from the GFS at the start.

Pierre, follow some of the folks you see at the top of the VSR list, or some of the names you see here. You will find you have some very good company down there. It's a marathon, not a sprint.
Post by iconPost by Luis75 | 2020-10-23 | 16:22:30
I am not in the race Pierre, but I can tell you that at my very first race (lasting 20/25 days) after 3/4 days I found myself around 15000 position. In that moment I realized Tipapacheri (top VSR) was beside me and understood that the ranking in VR is really not accurate.
Post by iconPost by Stevoo | 2020-10-23 | 19:27:34
its accurate, but always selects as the crow flies to the finish, which is not necessarily the fastest way, in most cases

Post by iconPost by zezo | 2020-10-23 | 19:29:20
It also takes some (hidden) waypoints in the calculation, possibly the while line, so you may get worse ranking even if you are closer to the finish as the crow flies.
Post by iconPost by Pierre | 2020-10-23 | 17:44:21
Thanks for your advices guys, we'll see!

Post by iconPost by YourMomSA | 2020-10-23 | 18:26:07
They finally put paging back into the rankings list! So you can see who's ranked near you even if you aren't in the top 50.

Hi guys and thanks for taking time reading me

It seems that there is a difference in wind direction between Zezo and VR : at this moment, at my position (Ticker), VR displays 108° and Zezo 118°. Which one is right?

Post by iconPost by BooBill | 2020-10-24 | 14:19:02
Yeah, I just noticed that myself. As far as I can tell the 00Z forecast failed last night. Router picked up and is running 06Z. Game I suspect is still running 18Z from yesterday. Go with dashboard for current conditions and game predicted path is probably the best way to go. It's affecting both Bermuda and Mauricienne.

Cvetan, I know this has been asked before, but is there a way to route off a cached GRIB? I'll take it one step further, old for the next 6h and newest after than, assuming game will sync up after next update.
Post by iconPost by TickerO | 2020-10-24 | 15:33:42
Thanks for your answer BooBill :)
I'll do this and will follow predicted path.
Post by iconPost by BooBill | 2020-10-24 | 15:44:04
Just got the early update of the 12z forecast and the issue appears to be persisting.
Post by iconPost by YourMomSA | 2020-10-24 | 16:28:06
It's really weird. Is it simply using outdated forecast data, or is it not advancing the wind at all? I don't think the wind I'm in is what was forecast for this time yesterday. But if it's simply stuck, then is the predicted path also wrong?
Post by iconPost by BooBill | 2020-10-24 | 16:38:21
It's too late now, but leaving "reuse tabs" off and hanging on to old forecast routes would be helpful sometimes.
Post by iconPost by zezo | 2020-10-24 | 16:42:36
VR is still stuck with 2020-10-24+18Z.

I can apply the same data, but the problem is it will get in sync sooner or later and you may get in the wrong place with the new forecast.

But then VR don't work on weekends, so the chances of the forecast moving before Monday are very small.
Post by iconPost by YourMomSA | 2020-10-24 | 17:06:03
But... Is it advancing according to the old forecast's projections? Or is it reverting to the old forecast every 6 hours as "current" such that we're effectively racing in yesterday's conditions rather than just yesterday's forecast for today? I think the latter... If so, then you'd have to apply the same new data as a repetitive forecast for every 6 hours.

I agree with BooBill that it's preferable to get it aligned with the game if possible, but I also agree with you that the timing of when VR solves their end makes the whole thing guesswork. You're right that they don't usually work weekends, as far as we can tell, but with Vendee in two weeks, it seems likely they're scrambling to resolve bugs ASAP, so hopefully someone is paying attention.
Post by iconPost by BooBill | 2020-10-24 | 16:53:43
Go for it. I just clicked off "reuse tabs" so I've got the current forecast saved and can always route with windy or another router for long term direction. I'm transitioning the latitude of the doldrums right now, so game wind for the next 24 hours matters more than anything else to me right now. There's my vote.

It's a messy... :(
Post by iconPost by Tigrou26 | 2020-10-24 | 17:30:17
I think it is not a problem with VR but with Nomads of NOAA, because we can't download directly the grib !

Post by iconPost by BooBill | 2020-10-24 | 17:41:32
GFS in NOMADS is running fine, it's GEFS and NAMS that are currently down.

Here's the latest:

"The team has been working all day but were unable to find the root cause of the GEFS and NAM problems that are preventing them from being on NOMADS. This data will be out over the weekend, with restoration planned for Monday.

They are still available via HTTPS and FTP on FTPPRD here:

We will be standing down for now and resuming at 12UTC Monday. We apologize for the impact this is having to your scientific endeavors, and look forward to getting this fixed."

Post by iconPost by PML | 2020-10-24 | 18:07:38
Does anybody know which grib file is currently used by VR ? Is it a mix of several files ?
Post by iconPost by YourMomSA | 2020-10-24 | 18:12:36
And, sorry to keep asking, but... Are we advancing in time against that GRIB, or is it being re-established as "current" every 6 hours? Are we sailing in yesterday's wind, or in the yesterday's forecast of today's wind?
Post by iconPost by Citizen Kane | 2020-10-24 | 18:29:40
I think it’s yesterday’s forecast of today’s wind...

Post by iconPost by BooBill | 2020-10-24 | 18:36:25
I don't have the old routes saved (who would have anticipated that), but my impression is I'm currently following the route from yesterday, as opposed to the current suggested route. So, I think that's the later, yesterday's forecast of today's wind.
Post by iconPost by Rostef | 2020-10-24 | 19:14:35
And I‘m sailing the routes predicted by the new Zezo files, but in the old VR wind of yesterday. I‘m more supporting Cvetan‘s idea of being prepared for a bigger shift as soon as the game adapts to the actual forecasts.
Post by iconPost by QuiVaSadoVaMaso2 | 2020-10-24 | 19:15:32
Hello Cvetan. Is it possible to recharge the 18z winds of October 23 ?
Post by iconPost by zezo | 2020-10-24 | 19:19:49
It is possible, but a bit pointless.

Because if and when the game gets in sync you may find yourself in the wrong place.
Post by iconPost by QuiVaSadoVaMaso2 | 2020-10-24 | 19:33:51
Ok, thanks, We'll wait until Monday then and sail with the winds of VR.
Post by iconPost by Rostef | 2020-10-24 | 19:23:20
The difficulty for Cvetan is probably that everyone will have different preferencies on that. If you‘re racing the bermuda, it might make sense to just go back to the old gribs VR is still using, but in the Mauricienne, the bigger picture will be more important over time, so it‘s better to be prepared.
Post by iconPost by orev30 | 2020-10-24 | 19:22:06
Hi !
I don't understand why the wind in VR and in ZEZO are different, I don't know what to do, in zezo the best route is HDG 32, TWA 66 but in VR if I go to HDG 32, TWA is 56, and if I Block TWA 66, HDG is 22 !! It is a big difference (excuse my bad english) !!
Thanks for your answers

Post by iconPost by Rostef | 2020-10-24 | 19:33:57
Hi Véro
If we would sail in the real world, we would very soon notice that forecast and real wind don‘t always match. So actually we should be glad VR offers us some kind of unprédictability. Zezo‘s winds are more actual at the time being. But you‘ll need to do some interpretation what you want to follow, zezos route in different winds, or what looks good in the game. It‘s a good lesson to learn. Enjoy the result, it makes this game interesting.

Yes of course ! I just wanted to know if it was a bug ! So it's not , ok !
Post by iconPost by BooBill | 2020-10-24 | 20:26:12
For orev30, I would treat Zezo as the best prediction of the future, beyond 2 days. Put yourself in a position to benefit from the long term strategy. However, for the short term, manage by what you actually see from the cockpit and understand that could change dramatically without notice. Sort of like real sailing.

Post by iconPost by YourMomSA | 2020-10-27 | 12:32:03
Well, it looks like I finished exactly 4,000th. Any idea how such a large fraction of the fleet finished within 3-4 hours of the leader? I don't mind that I finished 4,000th... I took a risk by pushing South while NOAA was under maintenance, and was terribly wrong. 3,999 boats simply beat me. Such is life. But usually in a fleet of 30,000, only 500 or so boats have foils and the relevant sail(s) while also navigating efficiently enough to finish within hours of the winner. So I took the risk figuring it's a Category 6 race so even if I'm terribly wrong, I'll finish 1,000th or maybe 1,200th. Dropping all the way to 4,000th was a bit of a surprise.

Maybe it's just that a lot of boats are tuning up for Vendee, so they bought foils and light sails with credits... And the new option for free boats to always have up to 2 programmations active without cards probably made a bit difference too. Is it that simple, or was there more to it? Did VR give a lot of boats free full options? Was the escort frigate dropping boats in with an advantageous position (at least relative to my stupid position) during the weekend? I'm not complaining about the situation - just trying to understand how so many boats did so well.

I stand to lose 29 VSR points. I gave up on VSR under the new calculation because it doesn't suit my racing style... I do better with a more logarithmic calculation, where one win can offset one awful finish, because I like to take risks. With the current calculation, I'll probably need a dozen top-100 finishes to overcome one 4,000th in one Cat 6 race. The current calculation favors risk-averse racers who consistently post high results without ever shanking one. I'm ok with that. It just means the occasional race like this one is going to knock me back pretty far.
Post by iconPost by PML | 2020-10-27 | 13:48:56
" Did VR give a lot of boats free full options?

This may be reason, as I surprisingly got a free FP for the Bermuda Race although I only had bought Light sails (bought with the free credits given by VR) for the Jamaica Express.
Post by iconPost by Pingi RIP | 2020-10-27 | 13:53:25
Everyone who started in the Jamaica Express started in the Bermuda Challenge with a free FullPack. So nearly the complete fleet was sailing with FullPack.
Post by iconPost by BooBill | 2020-10-27 | 13:57:58
First hats off to the winner, ugolino69, he pulled the exact move I contemplated, gybing north early in anticipation of the change to current wind. I just chickened out when I lost confidence it would happen in time.

However, I agree there were a lot of weird things going on here. A lot of top VSR sailors finished poorly and this was probably the race with the lowest average VSR ranking among the top 100 finishers.

Some points.

- FP was offered for free to many boats, but not all. I got my FP for free and without asking. Not everyone did though. But it seems like 90% were sailing fully loaded.
- When the winds got out of sync with updates that strongly favored the no router crowd. Sailing to the game predicted path gave an advantage if some continued following routings.
- It's very clear that not everyone was sailing in the same wind, especially after the change over. I had some private match races going on to the finish and lost them all badley and inexplicably. At the last gybe Cvetan was precisely 1nm ahead of me (he didn't know I was racing him). We followed the exact same line and he finished 3nm ahead. With dimishing winds that gap should have closed, not openned. At one point a teammate had a 25 degree bearing advantage on me at the same twa.
- The new engine is suposed to give better real time rankings and data on other boats. I find it worse. Constantly I put myself in a position to have better wind speed and angle. The cards confirmed my boat speed advantange over benchmark boats I was using, yet they pulled ahead. Inexplicable.

It's the last point that troubles me the most. I put a lot of effort into playing a good tactical game and if the results end up being random, when then I'm out.
Post by iconPost by YourMomSA | 2020-10-27 | 15:23:12
Thanks for the info. I have posted a topic in the VR forum to see if they're willing to limit the losses for this race. I hope I won't come off as too much of a whiner. I can live with the loss of VSR points, and I freely admit that 3,999 boats simply beat me. I just wouldn't have split so far from the fleet and adopted so much risk if I had known that most of the fleet had full packs, so it's frustrating that it will take months to recover from the VSR loss.

I think the new engine does better with the rankings. It's definitely far more stable. I haven't seen it jumping around like the old version did. Data on other boats, though... I don't know. Under the old version, I stopped looking at that. I found it to be a recipe for confusion and irritation. I guess I was too far out of it to have any idea whether or not random gains and losses were occurring. If that was real, that would be a serious problem with the game's basic integrity.
