2011-05-03 00:21:53 - let's return to one colour wind arrows
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 . . .

however,

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.

Rod, what on earth do you mean? Looks pretty clear to me.

Cheers,

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.

Great Bear Ice Race 2025


You can fly to Great Bear Lake Airport, but if the ice is good, instead hire a pick-up truck, load your disassembled DN into the cargo bed and drive, first following the McKenzie River north, and then straight across the lake to the start of our final Ice Boat series race of roughly 100nm in length. The Airport authorities have agreed to leave all lights on, so you should just about be able to see where you are going as you zing and rumble, PL-free over the ice!

Chile Islands RTI Sprint 2025


Across the Canal Puyuhuapi from Puerto Cines on the Chilean mainland lies the Parque Nacional Isla Magdelena, and further west across the Canal Moraleda from Magdelena lie the islands of the Chonos Archipelago. Returning for the first time since 2017 we find ourselves in vari-charted waters here, with the mapping between physical islands and their names not 1:1 but rather some:some. It’s only 26nm but you could get lost! Good luck.

Christmas to Christmas Island 2025

Two waypoints, start and finish, and between them 5827 NM of two oceans. Not much time if we want to sit at the Christmas Eve table. You will need to maintain an average speed of over 10 knots, maybe quite possible with this Maxi Trimaran, but prepare your vessel well and choose the best of the many possible routes. Hands up everyone who knew there were TWO Christmas Islands?! OK, maybe you have sailed this Sailonline course before... but it's time to get ready for the 2025 challenge of racing between Christmas Island in the Pacific to Christmas Island in the Indian Ocean! It also marks the conclusion of our prestigious Ocean Race Championship 2025. Please have fun! Fair winds!

Sinbad by Balloon 2025 - Carnarvon to Dondra


From here, our home in Bharatavarṣa is now north west of us – said Sinbad to his fellow balloonists. Perhaps we can ride the wind first further north, and then catch the winds that every year bring the rain, perhaps not. It’s 2600nm and we could be aloft awhile, so, Master el-Quarters, victuals only, no sandbags, provisioning the giant hamper. It will be not a picnic!
