The Axis

In the raw polar data, two vectors (one-dimensional array) define the graduations for both axis :

    "tws" : [0,  4,  6,  8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 40, 50,  70],
    "twa" : [0, 30, 33, 36, 39, 42, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 105, 110, 115, 120, 125, 130, 135, 140, 145, 150, 155, 160, 180],


These values will be taken as-is into the array generated:

However, if the Interpolated option is checked, the axis change to plots values every 1° (TWA) and ever 1 kt (TWS).

The Colors

In the Display as Array output, the cells are getting colored to represent the best sail used to reach that speed
The Colors are the same than the ones used on the Chart and in the Sails panel.

Here is how a Full Pack on a Class 40 boat looks like:

  • Jib
  • Light Jib
  • Staysail
  • Code 0
  • Spi
  • Light Gennaker
  • Heavy Gennaker

Of course, you can always hover a cell to gather the exact value and sail name in case you had a doubt.


The Raw Output textarea is only there for people who want to check that the content generated and placed in the clipboard is correct.

If you trust the generator, then you can forget about the Toggle Array button.

Save to File

Once the output satisfies your needs, you shall save it to a file so it can be used within an external routing application.

Just hit the Copy to Clipboard button, and paste the content generated into a WYSIWYG text editor. It is very important not to use Microsoft Word™ or any equivalent Application, because these editors do a lot of things in background, and store a lot more into the file than only simply the text you just wrote there.

On the opposite, a WYSIWYG (What You See is What You Get) lets you edit exactly what will be written in the file to the Hard Drive. Here is a non-exhaustive list of such text editors:

Sublime Text
Visual Studio Code

Of course, you can still use the filthy Notepad editor which is embedded on any PC installed with Microsoft Windows if you don't want to install an application for a single use.

Once you pasted the clipboard content into the text editor, then save it to a file, which extension shall correspond to the format you used to generate the polars (for example, your_file_name.csv if you chose to export in the CSV format).
