Wind differences between zezo and VR
Post by iconPost by Eldian | 2023-04-01 | 11:10:37

Hello,
as I am routing my boat on Olympic race, I'm surprised to see that the wind angles aren't consistent with the map drawings.
The value of the wind angle is 48.7° and the arrow on the map show a 0° or 5° wind.
The TWA value is also wrong.
Wich is confirmed looking at the map in VRO.

The map displayed by zezo : https://www.casimages.com/i/23040101023525191418149682.png.html

and in VRO :

The difference is obvious.

Can you help me with that issue ?

Thank you :)
Eldian

If you use some dashboard or another you'll notice that the actual inconsistency is between the VR sever and user interface.

It usually shows mostly during wind updates, but it seems that VR have not switched (correctly) to daylight savings time yet, so the discrepancy shows hours later.

Thank you for that explanation. But I'm not sure I quite get it. I'll check it out the next time I see this phenomenon.

So I understand what we see on the interface VR is not true?! We have to look at the dashboard

Yes, easily 10 degree difference sometimes. Which can lead to sail changes, going over optimum TWA and so on.

TWA locked at 75.

7 degree difference in TWD and half knot in TWS

hello everybody
First thing, I switch to "manual" sailing as soon as two sails approach on "VR" before putting a new program and I wait at least 10 to 20 minutes before switching back to "Auto Sail".
