The polar table file has the « .pol » extension. The maximum format is 32 lines for 17
columns, tabulation separator and point decimal sign.
If that format is not followed, an error message will appear in the log file of the Regatta
Processor.
9.2 Reading a polar diagram
The diagram below shows both sides, but usually, only the port side is shown, as both
tacks should be same.
The boat line is vertical, with the bow on the top. The radiuses feature the true wind angle.
Each curve represents the boat speed for a given wind speed.
