Chapter 1: Introduction 7
1.2 The Chartplotter Display
The chartplotter includes a small-scale world map that can be used for
route planning. Detailed navigation information is displayed when a chart
card is installed.
Once the position fix has been established, your vessel’s position, if on
screen, is shown as a boat shape, pointing in the direction of the current
heading (or COG if heading data is not available). If no heading or COG
data is available, the vessel is shown as a circle.
The chartplotter screen includes a status bar that displays chart scale,
with either cursor position, range and bearing or, when the cursor is
placed over the vessel, vessel position, Speed Over Ground (SOG) and
Course Over Ground (COG).
Any waypoints you have placed are displayed (unless you turned them
off in Chart Set Up as described in Chapter 5) and the current route is
shown. Data boxes can be viewed on-screen by positioning the cursor
over a waypoint, current route or chart object. The chartplotter screen
can also show additional information, depending on your currently
selected options, set up selections and data available from other
equipment.
An example chart display, in its default configuration, with a chart card
installed, is shown in the following illustration.
Several functions are available to control the display as follows:
• Zoom in/out and Pan the Display
• Offset the Chart or Centre the Chart around the Vessel
• Synchronise the Chart and Radar (if radar data is available)
Operation of these functions is described in Chapter 2.
