understanding maps question

To illustrate:

Plotting your course ...

As in Nisgeis' example, you've set a course to the north using the navigator's compass. Since the course line only extends to the center of the compass rose, your true heading must be read along the back side.

Taking a target bearing ...

True bearing to the target is about 307 degrees ... again measured on the back side.

Measuring target heading ...

This is the easiest method to plot your target's course ... anchor the line on your first fix, drag the compass over the target, then read the back side (in this case, about 089 degrees). If you like, you can also enter this target heading into the TDC by adjusting AOB.

I'm goin' down wants to introduce you to a couple of city gals and take you to dinner when your boats are in town (San Francisco), a great port town. Thanks. I could have never figured that one out!

:hmm: I could never figure out San Francisco. Tried going to a dinner party in Twin Peaks once ... and ended up on Fisherman's Warf.

Too many one-way streets ... scary when you turn a corner and see three or four rows of headlights coming your way.
