6.1.6 Keeping Your Ship in the Display Area (Ship Auto Center)
When you turn on the Auto Center feature, ECDIS automatically moves the
displayed chart area so that your ship is always in view. When your ship reaches
a point near the edge of the display (that you determine), ECDIS automatically
recalculates the center of the display, then re
− centers it so that your ship is at its
center. If Ship Auto Center is off and your ship travels outside the display,
ECDIS continues tracking your ship; you just can’t see it. To locate your ship,
simply turn on Ship Auto Center, or click the Center on Ship button on the
toolbar. Ship Auto Center automatically turns off if you scroll the display 3 times
in any direction.
