Route Du Rhum
Post by iconPost by toxcct | 2018-10-14 | 13:21:54

4 races have been opened on VR, one for each boat category :
- Ultimate
- Imoca
- Multi 50
- Class 40

Right now, I just noticed that Multi 50, which is supposed to be a multi-hulled boat, currently uses the mono-hulled "Figaro 2" Boat.

Also, the Ultimate uses a speed-augmented version of the multi/maxi_trimaran, with a globalSpeedRatio of 1.04.

Oh, and BTW, the "Route du Rhum" is VSR 2... WTF ?!

25 EUR/boat

Also note that VR has set Ultime Foil ratio to 1 (meaning, foils have no effect).
It used to be 1.04.

The remaining parameters and the polars themselves are unchanged.

Thanks. I'm going to wait a bit more before adding support for the race, and all observations on non-obvious changes from previous races are very useful.

"polar":{
"_id":6.0,
"label":"multi/maxi_trimaran",
"globalSpeedRatio":1,

Yes, they fixed it.
Post by iconPost by toxcct | 2018-10-17 | 12:35:39
They fixed THAT point.

But still Multi50 has Figaro2 polars, and Class40 polars seem to be faster than Imoca's (that may be correct, but weird anyway).
Post by iconPost by mak08 | 2018-10-17 | 15:49:55
Lol, yes, only that point.

But afaics, the IMOCA (imoca_60_new) are faster than the Class 40, (very roughly) by a factor of 1.6

bonjour
ça veut dire que les foils sont pas utiles?cela fait une petite économie quand même
merci
bon vent
Post by iconPost by toxcct | 2018-10-30 | 14:36:03
Read the entire thread.
The foils thing has been fixed now !
Post by iconPost by alulo | 2018-11-02 | 15:04:00
je gagne combien en mettant les foils
merci

In english please. People from all around the world try to interact here, so try to be understood as mush as you can too ;)

The foils have a progressive kicking window, depending on the wind speed and/or the angle your sail has with the wind.
At most, the foils provide a 4% speed ratio.

The best you can do to figure out is to play with this : http://toxcct.free.fr/polars/
and to read this part of the help section too : http://toxcct.free.fr/polars/help/chart_rightpanels.htm#_options

Good evening, everyone !

On the occasion of the Route du Rhum, two new inter Teams challenges are proposed : the first in Ultime, the second in Imoca. These two challenges are independent, teams can register for one or the other, and why not both !

To consult the rules and access the registration files, click below:

J'ai l'impression qu'il y un probleme sur les polaires avec
- un Class 40 qui va plus vite qu'un Imoca
- un multi 50 avec des polaires de Figaro

Post by iconPost by toxcct | 2018-10-17 | 12:12:40
Salut l'ami,

Oui, c'est ce que j'ai fait remarqué quand j'ai récupéré les polaires de VR à l'ouverture des 4 courses.

D'après les commentaires, VR a corrigé, je vais donc récupérer les nouvelles polaires immédiatement...

(et donc on est bien d'accord que c'est des guignols chez Virtual Regatta...)
Post by iconPost by meteo79niort | 2018-10-17 | 14:11:43
Presque...
Nous avons toujours 1 Multi 50 avec des polaires de Figaro
Sacré stagiaire... :-)

Post by iconPost by toxcct | 2018-10-17 | 15:50:57
Alors oui, j'ai vu ça (d'ailleurs, je l'ai recommenté un peu plus haut dans ce thread).
Effectivement, les polaires de l'Ultimate ont été corrigées, mais le Multi 50 est toujours sur un profil de Figaro 2, et le Class 40 a toujours des polaires plus rapides qu'un Imoca (mais bon ça, chez VR, c'est peut-être normal, vu que ces polaires sont identiques à celles que j'avais pu récolté par le passé sur ces 2 types de bateaux)
Post by iconPost by meteo79niort | 2018-10-18 | 05:14:59
c'est bon, cela semble corrigé

Bonjour à tous !

Je viens de découvrir cette interface qui, à ma grande surprise, va bien m'aidé pour mes routages de nuit.

Je reviens donc vers vous juste me confirmer 2 infos:

- Mise à jour des fichiers météo heure française, 7, 13, 19 et 23h ?
- Dois je à chaque session éliminer les cookies et le cache ?

Merci à vous !

Looks like there also are proper[1] Multi 50 polars now (15% faster than IMOCA).

[1] YMMV.

Hello, I would like to know the difference between Imoca_60_new and imoca_60.
It is to create the polar with toxcct.
Or I go directly to toxcct by clicking Imoca 60.
cordially
Guy
Post by iconPost by toxcct | 2018-10-26 | 11:05:19
Same thing; imoca_60_new is the technical name, but the boat name appears as Imoca 60 on the Polars App.

If you reach the CSV Generator, you will see that there is only one kind of Imoca anyway.

Hello Guys,

Do you know when the 4 races open here?

Thank you.
Post by iconPost by toxcct | 2018-10-28 | 19:59:25
4th leg is supposed to launch on 10th of November
Post by iconPost by HAVANA | 2018-10-29 | 12:36:52
Sorry toxcct but I speak the 4 races on the "rhum".

I knox it's the 4th november but I just want to knox when they are available in Zezo.

Cordially
Post by iconPost by HAVANA | 2018-10-29 | 15:26:43
knox = know

My english is not good... Sorry
Post by iconPost by HAVANA | 2018-10-29 | 16:44:40
Je viens de voir que Zezo a ouvert les trajectoires pour les catégories Ultime et Imoca.

C'est bientôt pour les 40 et Multi. Les polaires sont rectifiées?
Post by iconPost by toxcct | 2018-10-30 | 08:23:32
My own polars are fixed, yes.
Zezo will probably get his ones online soon too.
Post by iconPost by zezo | 2018-10-30 | 13:59:37
I've added all the races now. Please drop me a note if you notice some copy/paste error - wrong speed in chart/polars, or bad link/race name.
Post by iconPost by Dogzilla | 2018-10-30 | 16:52:55
Thanks for all the job you do.

Good morning, everyone,

What options should I select for a race without IMOCA options ? Thank you.
