1. Ship to Shore VHF Radio
A VHF radio is offered as a stand-alone option or with
the selection of the navigation package option. It
provides reliable communication between vessels,
and from ship to public or private shore stations. It is
programmed for two-way communication on all the
International, US and Canadian channels plus recep-
tion on separate weather channels, and the interna-
tional calling and safety channels (16/9). The VHF
radio with microphone is mounted on the helm. If
equipped, additional information is included in the
manufacturer's literature included in the owner's
packet.
2. GPS/Plotter
A GPS/chart plotter is an electronic system through
which a navigator can determine his position regard-
less of weather. The GPS sensor receives high
frequency radio signals generated from satellites to
generate coordinate readings on the display. The
GPS navigational unit takes this information and
Engines, Drives and Instrumentation - Section E
uses it to determine the vessel's exact position and
indicates the vessels position on the chart plotter.
The chart plotter allows one's course to be plotted
electronically. Factory installed GPS/Plotter system
is one of the optional navigational packages offered.
It is mounted at the helm. If equipped, refer to the
manufacturer's literature included in the owner's
