Note: the green line starting at the boat icon projects your course based on your current
COG (course over ground), which is different from your compass heading when you are
affected by current. Very handy for crabbing into the current when necessary to avoid
being swept off course and onto rocks/reefs!
The purple line shows your current heading. The yellow line shows the wind direction.
The blue line shows the tidal current direction. These lines are referred to as vectors in
the manual. Touch any object on the screen to get information. Touch a spot on the
chart and the distance to it and bearing will be shown.
We use the paper Maptec Chartbook for pre-planning, for continuous orientation
underway and for pre-locating rocks and reefs on our planned route. We use the chart
plotter to track our position underway in detail, for occasional confirmation of chart
position, and for navigating in passes and coves.

From the Home screen you can choose to show chart with radar overlay, radar only,
or radar and chart plotter side by side. We normally leave the unit preset to radar
overlay when the radar is activated; sometimes we find it beneficial to show a side by
side display for greater radar clarity.
We do not cruise at night or in fog. The radar is especially useful should one be
unpredictably
enveloped in fog. If there is fog either visible or in the forecast, we stay at
our mooring until it lifts (normally before noon). Safety is paramount. We normally do
not turn on the radar on the 12 volt panel unless we need radar.
