    This sounds like what I think of as a "heading".
    It accounts for the current set - so if you started with a true initial
    direction to the destination, and did a triangle of current speed and
    direction, and desired track at the vessels speed through the water, the
    third  side of the triangle would be the vessel's effective speed and true
    track made good, then corrected for variation and deviation to arrive at
    compass heading.
    This "compass heading";   is this called the compass course??
    
    Thanks again for the helpful tips.
