4H7: Electronics: Plotters/Electronic Charting Systems
The boat is equipped with Raymarine plotting
software which runs on any of the Raymarine displays at
either helm; the software includes charts and even photo
images where available. It will always make your location
easily identifiable.
THE ELECTRONIC CHARTING SYSTEM IS NOT
A SUBSTITUTE FOR CAREFUL STUDY OF
TRADITIONAL PAPER CHARTS. You are
required by maritime law to use your paper
charts for navigation information, especially
since electronic chart technology does not
always permit full cartographic details to show.
The Electronic charts are for convenience only!
When turning on the Raymarine displays, turn on the one in front of the
helm wheel first and turn on the radar scanner there; unless this is done,
the others will not function.
4H8: Electronics: Raymarine Radar
The boat is equipped with a radar set that allows
display of a radar image on the Raymarine screens at both
helms, the same ones that show navigation information.
These are used, combined with the electronic chart unit,
for operation in restricted visibility, with the radar primarily
serving as a device for collision avoidance while the chart
unit provides position.
When you turn on the
Raymarine
unit, it will display
a data screen. Press the power button again to display
the radar information.
Proper and safe use of a ship’s radar requires lots of practice and careful study. While
you are using the boat, you can have the radar on as much as you like to get used to the way it
displays images, but for detailed operating instructions we refer you to the radar’s own
complete manual.
4H9: Electronics: Rudder Indicator
Hele Mai
is equipped with a Raymarine rudder indicator at each helm. It is turned on
when the autopilot power is on. Operation is entirely automatic. (In the illustration by
paragraph 4H2 above, the indicator is off; when it is on, the arrow points at its scale.)

photo imaging of the harbor was also available.
