O, Is that mean, we need to sail 150 TWA,  but we need to do some gybing. the average TWA will be (-175), so mostly on port, and sometime on starboard. 

see the pic. the solid line is exact course, and the dashed line is mean average course (need some gybing).



 

？ anyone know how to convert it to RNC ?

Thanks Nick.

Finally I fix it. Following is my steps.

1. I found I can use that feather in my VirtualBox PC.   So It is not the issue in Exp.
2. I uninstall and reinstall Exp. not effect. because there is a core app still in system.
3. I use "Expedition system restore" for restore the Exp. It still don't work.
4. I create a new user in my Windows and install another Exp. It is working. That mean the issue maybe in the system dir.
5. I uninstall the Exp, and clean the Dir of Exp under drive C:/, and cleanup two Exp record in system registry。   and install Ext。    OOOOh .  I get a totally new Expedition without any problem.

I hope to inspire u. 

Is not because that, still don't work.

 

Hi,

I just learn how to use expedition from NorthU, step by step following the video ... Everything is ok in the start. 

but after I create some visual marks, the simulate feature did not more work.

When I set the position,  A green boat will be on the screen.  after that there is no any reaction when I click the simulate button or set Hdg value. 

Would you please tell me What's wrong?

Thanks
