When I compare a known course between two marks in my cruisers guide to the same two marks in OPEN CPN
they are not the same. Off by 10 degrees?
This is the 10 degrees between True North and Magnetic North.
Are there different Charts
? Is there some way to charge the orientation?
I'm using charts
. Description of NOAA Raster Navigational Charts (NOAA RNCs�)
They look great and have all the nav marks but I would like the info to be the same as the paper charts.
Got any Ideas
