Do you plan to choose the "boat" charcteristic i.e. speed = f( wind strength, wind tack)?

http://sail.zezo.org/xr/chart.pl is maxi trimaran, but uses half-degree wind grid. should be useful for the general strategy.

I'll update it with the regular 1-degree grid - probably tomorrow.

I use it until your update!
Thank you for your response!

Cvetan thank you for your answer but to start A18H, routing does not match with the wind?
Post by iconPost by Ke20 | 2013-02-11 | 09:01:54
Hi zezo, thanks for you website. But, like buez-ar-vro says, routing are false and does not match whith the wind. What the matter ?

Hi all.
Thanks Zezo for all the work you did with this wonderful tool.

buez-ar-vro, Ke20> Yes I noticed the same behaviour. I had a proposal for a route at 10�TWA. I guess the boat would have not been much farther :)
This is weird because sometimes the wind data did match but at +12 / +24 hours and so on.
Post by iconPost by buez-ar-vro | 2013-02-11 | 13:50:43
it's a shame that the routing does not work, it penalizes people who use zezo, and thus gives the advantage to users vrtool, avalon etc etc. good luck to you anyway,
but I said that for me is the best zezo router, even if it is not a day for shopping
Post by iconPost by DarkNounours | 2013-02-11 | 16:53:49
"It's a shame" well I use Zezo pretty much and it is much more proxy friendly than vrtool for example. But instead using these words we can kindly ask to Cvetan if he could spend some time to get the tool work on this race, that would be wonderful.
Otherwise I am afraid that we will have to get real navigation skills ;)

I stand with you DarkNounours. We all must be thankful to Cvetan for all his very useful work and not use that kind of criticism

Best greetings CVETAN for your update!
now your tool is nearly exact. A small diiference (-) with real speed of boat. It's new generation of boat!!!

for buez ar vro
ARe you running? i can't find you on VR
Post by iconPost by javakeda | 2013-02-18 | 03:13:08
FWIW: the CSV 'complete' polar file linked in VRtoulz 'polars' page is not congruent with the polar values obtained through the graphics tool available on that same page.
Seems life the Zezo model [on the Austral page linked through paco] IS congruent with the boat speeds I get directly through paco.
I wonder if you have a better polar file that you might share.
[Speadsheet buff that I am, I want to do my own analysis of polar VMGs.]

hello Cvetan, I tried to look for my road to Horn, but I'm blocked on the right of the map. I can't move to the horn. How can I do ?
Thanks for all of you works, because without you, I'm nothing ;)
Post by iconPost by Gaborje | 2013-02-23 | 15:12:03
Hello Cvetan, I have the same problem than Ke20 ! No new road to the Horn.
What can I do to get it ?
Thanks a lot for your help
Post by iconPost by zezo | 2013-02-23 | 20:48:57
You can move left to the Cape. Boat will take the shortest distance, no matter on which part of the chart you place the point.

Ideally the chart should have been endlessly scrolling, but there is a problem with the way I've done the isochrone and track lines.
Post by iconPost by Gaborje | 2013-02-23 | 21:09:06
It works !!
Thanks very very much.
And one more time: CONGRATULATION for your wonderful job
Post by iconPost by Titou | 2013-02-23 | 23:04:15
Hi Cvetan,
Sorry but I did not get your latest explanation.
I can reach the Cape when scrolling by the left but when i manually position a destination point near Cape Town, i get the same road as the one i get when doing 'Go to Cape Town' and i still cannot see my entire road.
Would you have a tip please ?
Is this going to be fixed at some point ?
Thank you in advance and many thanks for providing us with such a useful tool !!!
