Ah, the Magnetic Compass!  A staple item in the inventory of any sailor.  Many a sailor has cursed the day he set sail without one, or lost one to damage or accident.

Setting Marks

Before you can even get to the rest of this section you need to learn how to plot, or set, marks.  It makes use of the command:  ship mark add <route number> <location name>.  So with the mark example1, I would have sailed to 1269, 748 then entered the command, ship mark add 45 example1.  This would initiate this mark as the first in the string of marks linked by Route Number 45.  Usually, with my sailing at least, it would be the first and only mark under that Route Number.  But since you also see example2 & 3 with the same Route Number, Route Number 45 is designated as a Course.


Using Marks

As you see in the example marks above you, examples 1,2 & 3 are linked together into a course, Route #45. Example 4 is just a stand alone mark because there is no other mark with the same Route Number.

Now, if you were to set a course to example4 then your ship would sail straight to those coordinates (1027, 747), and then stop. If you were to set a course to example1 then, it would sail there, then to example2, finally stopping at example3. If you set a course to example2, then it would sail there, and then stop at example3.
