[I'm goin' down]

Bowfin. You confused me. I understand relative and true bearing. All you are saying, aren't you, is that when you have plotted two, three or four range and bearing readings, you can use the compass/ruler tool to draw the target's true course on the Nav Map? I knew that, and it is very old news. However, if you are using the compass/ruler tool to plot the various bearings and ranges, which I believe you cannot do (note that Mr. Channing recommends using the protractor tool and the ruler [or compass/ruler] tool for plotting the varioujs range and bearing readings), then you have lost me. My short answer to your post is that it did not occur to me that you were offering an explanation to a question I did not pose. Using the compass/ruler tool to draw (plot?) true course is well established.

Nisgeis and Roger/Dodger - thanks for the explanations, but Bowfin lost me in his translation. See the paragraph above. BTW-- good explanations of true course vs. relative course in any event.

Nisgeis, I posted 3 questions above. Provide me whatever information you can muster, please.

p.s. I am at the Battle of the Philipine (spell?) Sea in TMO2.0/RSRDC. My boat is pointing in the wrong direction. The task force on radar is at 26,650 yds. at 185 degrees. Hmm. Aft tubes? Pretty scary for my first action with map contacts off! I may turn the boat...
