26 HSB Series Chartplotter
Centre the Vessel
GOTO SCREEN ROUTE FIND SHIP
D4160-1
When you press FIND SHIP the following occur:
• The chart is re-drawn with the vessel’s position in the centre.
• The cursor is homed onto the vessel position and moves with it.
• When the vessel moves near the edge of the chart window, the chart
is redrawn to place the vessel and cursor at the centre again.
• Whilst homed, the status bar indicates vessel position, speed and
course over ground.
➤
To release the cursor from homed mode press the trackpad to move the
cursor away from the vessel’s current position. The status bar shows the
cursor position, range and bearing.
Synchronise the Radar and Chart
If you have a combined radar/chartplotter display, with chart and radar
windows on, and you have selected Radar/Chart Synch in Chart Set Up
(
see Chapter 5 ). FIND SHIP also synchronises the radar and chart
images as follows:
• The chart is redrawn so that its centre position matches that of the
radar display. The radar is redrawn to the scale and heading mode of
the chart.
Note: Depending on the topology of the coastline, the radar returns may
not relate to the charted shoreline, the radar image will therefore be
different to the chart display. For example, a gently sloping beach with a
cliff several hundred metres beyond the charted coastline, the cliff is not
shown on the chart but will be displayed on the radar image.
Changing the Chart Scale
The RANGE key allows you to change the chart scale so that you can
see a smaller or larger area on the screen.
Plotter mode is available to allow you to zoom into a smaller area, even
when no chart data is available for that scale. Chapter 5 describes how
to set plotter mode on/off.
You can change the chart scale for two purposes:
• To see either more detail (of a smaller area) or a larger area (in less
detail) on the screen
