1. INTRODUCTION
1.1 The Chartnav 343
The Chartnav 343 is much more than a highly reliable,
innovative chart plotter. It can share and access information
via an NMEA data link. It can quickly step from the chart
screen to three other information packed screens.
The Chartnav 343 on its own is a powerful charting aid.
Add a GPS or other position-finding instrument and the
vessels position and track can be displayed. Add to that an
autopilot and you have an excellent navigation system.
The Chartnav 343 is available with a mono or colour screen.

1.2 A Word of Caution
You and your analytical abilities are the most important part of
any navigation system. Do not assume that the co-ordinates
you receive from your position-finding instrument are
infallible. Remember also that the Electronic Charts are only as
good as the paper charts they were digitized (copied) from.
The Chartnav 343 is intended as a supplement to standard
paper charts, not a replacement. A prudent navigator always
double-checks his data against other navigational aids, the
safety of your vessel and your crew is at stake.
1.3 For the New Chartnav User
In writing this manual we assume you are familiar with
marine navigation and the use of latitude/longitude co-
ordinates.
Learning how to use the Chartnav is best done before you
find yourself at sea in a heavy fog! Remember your Chartnav
343, and any position-finding device or autopilot must be
installed correctly for safe navigation.
