Problems with weather routing / VVOR Leg 6
Posted: Tue Apr 21, 2015 2:02 pmHi all,
Since the start of Leg 6 of the virtual Volvo Ocean Race, my VRTool weather routing feature has been behaving strangely. When I do weather routing, the program seems to assume that the next wind update happens 9h after the current one. From then on, it keeps a 12h cycle, resulting in radical changes in the proposed course at 21h, 33h, etc. after the current wind report. Interestingly, when I design a track following the calculated route, it correctly warns me that I steer a bad course to the wind between the time points listed above and the actual wind updates (12h, 24h, ...).
I have tried to fiddle with all time settings I could find, but seem to have missed the crucial one. Can anybody point me to the setting that I might have got wrong? Any help is greatly appreciated.
