6 AIS: Introduction
The International Convention for Safety of Life At Sea (SOLAS)
requires that all vessels greater then 300 tons and all passenger
vessels to be equipped with AIS (Automatic Identification System)
transponders. These vessels broadcast permanently through one
or both of two dedicated VHF channels.
The transmission may include information about the vessel’s MMSI
number, call sign, name, position, course, heading, speed, rate of
turn and type of vessel.
Your system can receive and display AIS information when it is
connected to an AIS receiver. All AIS vessels transmitting in the
local area are shown on your
Chart when AIS is enabled. This
provides important information to supplement your
Radar and
helps to clarify radar targets and avoid collisions.
Note: AIS notification on your system is automatic and
requires no operational instructions. However, you can
customize the settings for the AIS display on your GB40.
If you change the filter options in the AIS Setup Menu, the
changes may hide some vessels on your display without
your knowledge.
If you change familiar settings, the new settings may
mislead you about a vessel's bearing and speed.
AIS is a tool to assist with safe navigation, but
responsibility for its use rests with the skipper.
