One thing Im having trouble with...
When Im getting a report "smoke on the horizon bearing 310" for example.
Im currently on a heading of 110.
What I understood is that I plot the heading Im on...
then take the difference between 360 and 310 = 50 degrees...
So the difference between my course and the "smoke on the horizon" is 50 degrees.
(Am I even close to being correct in my assumption?

)
But how would I know if that 50 degrees is to my starboard or port?
