Eric responded - in part: >Compass course is the course you see on your compass with no correction for >deviation or variation. 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. Brian W Brian Whatcott Altus OK Eureka!
