piloting tips and techniques 83
Th e running fi x position lies at the bottom right, where the fi rst and second LOP cross.
One way to minimize running fi x confusion is by using a bolder TR line. Th e dashed line
represents a mirror image of the fi rst LOP.
1000 to 1100 at a speed of 4 knots. Plot the bearing as a dashed line
overlapping the TR by two inches.- Plot and label the running fi x. Plot your second bearing, but instead of
drawing a line, place a small tick mark where it crosses the dashed fi rst LOP.
Circle the dot and label it with time and position type (e.g., 1100 R Fix).
Longshore Piloting When Landfall Is in Doubt
Approaching landfall aft er even a short passage is exhilarating, yet it can also
be a period of doubt. If visibility is getting worse in squalls, fog, or mist, will
you make the sea buoy that marks the entrance between those jetties?
One technique that’s been used for decades in such a circumstance is
called longshore piloting. Simply lay your courseline purposely two or more
miles to the right or left of your destination. Th at way, you’ll know—without a
doubt—which way to turn to run down your landfall.
One way to ensure further success in longshore piloting is to make your
turning point a charted contour line (one of those black continuous lines that
indicate constant soundings along the line). Once your fathometer indicates
you’re on this line, turn toward your destination and sail down the line. Follow
these easy steps to success in longshore piloting:
- Lay your trackline two miles upwind or upcurrent of your intended
destination. - Find a prominent contour curve marked with depth that parallels the
shoreline.
