chart plotting and preparation 45
Complete 90% of Your Navigation by Annotation
Many charts contain a confusing web of lines signifying Loran-C time diff erences,
territorial sea boundaries, naval training areas, underwater cables, and so forth.
Our tracklines, which we add to our
paper charts, make up the foundation
of our navigation. What follows is a way
to make these stand out boldly from all
the other symbols on our charts.
MARKING, LABELING,
AND TAPING TRACKLINES
Pencil it. Lightly pencil in your tracklines.
Enter these into your logbook, but do not
label them on the chart yet (see below).
Aft er cutting your chartlets, draw in your tracklines. Use your transfer points for reference.
Th en, stack the chartlets in order. Finally, lash your chartlets to the sketchboard with
rubber bands.
