Aha ! Well since I am used to sailing and boating I do not use my protractor and ruler in that way. I draw a line and my ship is the center and the line will give my course by using the nav disc which is on the side of the nav map.
That is why now I have the Tool Helper closed always so I just see the ruler icon and compass icons. Not the discs.
Always put the ship at the center cross when working with your map.
Basic sailing navigation techniques ehehehehehe.
But I understand why the game has it that way now.
Oh by the way. Not everyone will have the C:/Ubisoft/Silent Hunter 5 directory. Not everyone uses the bought version of the game these days you see. Some use the free version. It is however by default in the program/x86 folder in Windows with the Cfg files in the Documents SH5 folder.
Ashikaga.
