www.ukho.gov.uk (click on the "charts" link) for a list of world-
wide Admiralty Charts and Publications agents/distributors.
For further details about acquiring and using these charts, see
"Navigational chart CDs" starting on page 2-5.
If you're using BSB charts, make sure you use Maptech Chartkit's
Second Edition (or higher) BSB-format chart CDs (or anyone else's
BSB-formatted 2.0 CDs). If you try to install one of the First Edition
CDs, you'll receive an error message, and will be unable to com-
plete the installation.
Each of the six features briefly described below is part of both
chart views:
Vessel position predictor line
The green line extending straight out from your vessel's sym-
bol is your position predictor line, which predicts what your
position will be at a future time, based on your current COG
and SOG. You can set this time to predict your position in one
minute, two minutes, three minutes, five minutes, or 30 min-
utes, or turn the line off completely; see "Customizing chart
setup options" starting on page 4-35.
Range rings
Range rings are two sets of fine black circles that surround
your vessel, which is at the center. The radius of the inner ring
is shown in a small box in the lower left-hand corner of the
screen. Because the range rings surround your vessel, they
help you find your position on the CHART screen. For details
about range rings, see "Range rings" starting on page 4-37. To
see an example of range rings on the CHART screen, refer to
the sample display screen on page 1-22. You can set the dis-
tance units to statute miles (mi), nautical miles (nm), or kilo-
meters (km).
