Page: 1 2 3 Next

This different colour wind arrows are confusing.
We are used that darker colour is stronger wind and here now we have opposite with slow winds.If one is planing fast his future route he could easily make mistakes,when sailing in slow winds.
Therefor I ask the organizers to return to good old one colour wind arrows

I like them and will not give them back :)
Could this be solved by personal preference files?

I must admit that I too would like the wind arrows in one colour. I would suggest, however, a return to the standard convention of black arrows with "feathers" to indicate the wind speed, in the same manner as UGRIB. Re-inventing the wheel is seldom successful.
If it breaks, it's not strong enough--if it doesn't, it's too heavy.
Wind barbs are a bad idea as that draws them as arrows opposite of the TWD... Most SOLers would be very confused by that imho.
Also, many grib viewers use colour in a similar manner - indeed data visualization applications from many disciplines do...
So no wheel re-invention is happening ;-)

Flash running in a browser cannot write to your local file system - even if it could there would need to be facility within the client to set such preferences...
Would make the client more complicated (visually) to provide such options, and as they cannot be persisted the user would need to set them again every time they load a race!

The usual conventions regarding wind directions and how they are described have major contradictions----a "North" wind blows towards the 'south'. So, if the air mass flows towards the south (which is the convention in SOL), the 'flow arrows' point south, but it is a 'north' wind.
When I plot a course, I must lay out the ruler tool pointing 'Up' wind, which is opposite to the direction of the SOL arrows. I don't know if its just me, but I always get 'slightly' confused each time and need to remind myself that the numbers in the upper right corner are the opposite of the SOL arrows direction. If all this sounds confusing, so am I confused.
p.s. With the barbed arrows used in UGRIB. if it is a 'north wind', the wind arrows point TO the north.

Interesting thread.
For my part, I have found the following:
1) The color spectrum is, for me, far more intuitive as it relieves me of having to use the cursor and time-slide to determine wind strength at various locations in future time. I also find it has greater visual appeal

2)Nites are always tough but I have been able to determine wind direction/strength with just a few tweaks on the screen for the light-blue 1-3kt winds.

3) I also find the arrow direction to be intuitive as they point to direction the wind is blowing TO. Fortunately, I have not used gribs enough to get used to the fletched-arrow version.

I like the change(s). I think it is a useful evolution of the simulation and I hope for more in the future. Anything to avoid Generalized Apoptosis!
I'm in favor of the new colored coded representation . . .


is there a way for the values of the isotachs on the weather side to be equal to the polar chart, whichever one would be easier to modify.

the colors match but the numbers do not.
None so blind
Rod, what on earth do you mean? Looks pretty clear to me.

I worded that badly, sorry Rod - what I meant to convey is that I believe most on SOL find it intuitive that the TWD arrows match how they would feel the wind were they actually at the location. And that wind barbs point in the opposite direction to this... Mets may easily understand barbs but every sailor I know (and a few are both) still indicates wind direction visually, whether on a diagram or using hand gestures, like here in SOL.

Vasco da Gama Ocean Race 2022

Point Yacht Club welcomes Sailonline to the 2022 running of the classic Vasco da Gama Ocean Race. This race is the oldest established international sailing event in South Africa and traditionally starts in the bay of Maputo, the old Portuguese colonial capital of Mozambique and finishes in Durban. Last year, and now again this year, the race was/will be from Durban to East London - circa 250nm in native Cape 31 speed machines.

San Francisco to New York 2022
Cornelius Vanderbilt, who made his money - that his descendants enjoyed to spend sailing and racing yachts - by recognizing that getting from the East Coast to the West Coast of the USA was best done by rail, would have been more than a little amused to see SOL organizing yacht races over the very route by water he made redundant. It's about 13,000 nautical miles, which compares with less than 3000 statute miles by train! Six years ago, the best SOLers managed to complete the passage from San Francisco to New York in around 36 days, sailing our much-used veteran ocean greyhound, the Super Maxi 100. Time to try again, this time on the VO70. If you aim for a SOG of 18kn, it'll only take you a month.
