charts. The plotter function is particularly useful when you’re
fishing out in the open ocean and using stored tracks and way-
points as reference points. The 961 automatically displays
your boat symbol on a north-up grid of lat/lon lines while it
plots your position and waypoints. When you’re using the
961’s plotter function, the menu keys to the right of the chart
views still let you perform the same functions as when viewing
a chart.

standing electronic charts” starting on page 4-2.
Navigational chart
CDs
You enhance your 961’s usefulness tremendously by using
chart CDs for the regions where you plan to travel. Further-
more, new electronic charts are very likely to be far more cur-
rent than your paper charts. Northstar recommends that you
acquire electronic charts, although it is possible to use the 961
and navigate without them.
The 961 is compatible with either of the following types of
charts (or both):
•
BSB 2.0-format navigational charts (ChartKit or ChartPack
CDs) supplied by either Maptech or NDI. These are
high-quality, high-resolution NOAA digital charts provid-
ing chart coverage for most of the world. Each CD con-
tains about 75 to 200 different charts covering a specific
area of coastline.
•
Hydrographic Chart Raster Format (HCRF) navigational
charts, such as ARCS chart CDs supplied by the United
Kingdom Hydrographic Office (UKHO). ARCS charts
(Admiralty Raster Chart Format) are raster images, digital
reproductions of official British Admiralty paper charts
that provide superior chart-image quality and global chart
coverage on a total of 3000 charts.
All the data on these CDs comes from scanning land-mass
shapes, nav-aid names and locations, depth contours, and
other information directly from the official paper charts into
an electronic format used by the 961. Between the two types of
chart formats, you have chart access to every major port, all
popular boating areas, and major shipping routes. Each CD
