...what I mean is a legend, giving a reference for the colours used in the shading.

This is existing with the "Colours"-window, but so far only for "Wind 10m", "Boats", "Race tracking boats", "Ensemble", "Optimal" and "Sails"



When shading with current or Sig wave height etc. I need to know, wich "Shade/ size max" value I have used in the weather settings in the background. Depending on this input a red colour on the scale could mean anything..
Therefore a colour legend on the side as shown above for wind would be helpful, for a quick overview for myself but also when sharing screenshots with the crew etc.
Of course there's the possibility to display contours (well, at least for the grib file, but not for a routing shading...), but the numbers on the contours are not easy to read, so again a legend would help for a better overview.

Right now its possible to show a colour legend of "Wind 10m" in the Colours Window.
It would be nice to have the same for current speed, to have a reference when using current speed colour shading on the chart.

What are the update times for the EC HRES?
When I download a 10day forecast: is the full forecast available immediately? Or does it start with a forecast for the first few days early in the day and then the longer forecasts become available throughout the day? 

I noticed that for example when I download a 10day forecast at 8am UTC it just goes to about 3 days into the future.
When I select "previous run" it downloads 10 days into the future - but that's obvioulsy the run from the day before.

Would it be possible to integrate an info panel in Expedition showing the update times for different weather models / which model can be downloaded right now / when the next model will be available together with the max available forecast range for the specific model?
 

It also makes sense to draw race notes over land areas and select "avoid in optimal routing" instead of using the "avoid land feature" as routings will run a lot quicker then.

Hello,
I'd like to carry out a statistical routing analysis for the Fastnet race for the past 10years considering not only wind but also current.

For wind I'm going to use the Copernicus reanalysis grib files. That's all straight forward.

For current I intent to use SHOM or Proudman tides (unless there's an even better way(?) ). So far I don't have a subscription, so before doing that I'd like to understand a few things.

1) Are both (Proudman and SHOM) usable in Expedition? On the Expedition website under sales I only find SHOM tidal currents for "Northern and Western France"
2) If both are usable: What is the difference between them? Is there one model considered to be "better"?
3) How far do the models rach back into the past? Is it possible to use them for routings for the past 10years?

4) And now the tricky one:
I expect that the SHOM / proudman models use different tidal coefficients for different dates, so the strength of the current in a certain area will vary over the tidal cycles.
While I can offset the starting time of the multi-year routings to always have the same relation to high tide like on Fastnet starting day (by offsetting the routing starting times by for example one tidal cylce / 12h 25min) and thereby getting at least the right current direction this would however lead to varying current strengths depending on the varying tidal coefficient.

So ist there any way to use the "fixed" current of the 2025 Fastnet with its tidal coefficient for all the routings with the weather from the past 10 years?
