matrix of dots, the vector chart is a series
of lines and shapes. The shapes are then
filled in with colors.
One of the biggest benefits of vector charts
is that navaids and other points of interest
are specified in the chart data, so the
plotter can highlight navaids, and do intel-
ligent things when the vessel or the cursor
gets near a navaid. This increased flexi-
bility is virtually boundless in the power it
offers.
Another advantage is the ability to “layer”
the data. The user can shut off certain
layers so the display is less cluttered.
One of the drawbacks of vector charts has
been that they don’t look identical to the
raster charts. With advances in technolo-
gies – both in cartography and marine
electronics – this disadvantage is
disappearing.

Purchasing charts
Purchasing charts for your 972 is quick
and easy, because all available charts are
already stored on a hard disk drive in its
processor module. There’s no waiting for
delivery or visits to dealers — you only
need to purchase a chart permit to use
them.
To purchase additional charts:
1. Press the STAR key several times to display
the Passport OnBoard screen.
2. Note the Passport OnBoard serial number,
and contact Jeppesen Marine by telephone or
the Internet to purchase the chart permits you
need.
3. Enter the chart permit and press ENTER .
4. Wait for the chart to be activated (up to five
minutes).
In addition, a menu key for purchasing
charts is displayed on the chart screen,
whenever there are additional charts that
you have not purchased, at the current
vessel position.
