By right-clicking on the map, on a boat or on a POI, you can get a contextual menu. One of the choices in this menu is "Draw a Grib esteem":
2 calculations mode can be selected and mixed:
- An estimation with a constant wind angle (TWA)
- And estimation with a constant heading (loxodromic)
The start date can either be:
- The current grib's date
- The date of the next vacation.
On the screen shot mode is set to TWA, and start date is at next vacation.
You can define up to 5 sections (Here the first is set to TWA=61° during 87 vacations). The esteem is drwn on the map and you can choose to keep or not the POIs. In this case esteem is red because a collision with coasts has been detected.
This is really useful for testing different options and find the best one.
