Automatic identification system (AIS) and plotter Interrogation.
Modern Navigation has progressed, and most sailors will opt for electronic navigation systems rather than chart plotters. We will go into detail on how they work, some of the features, and importantly how to avoid some of the shortfalls that happen all too frequently.
The interactive chart plotter display shown below depicts some of the features now available with Automatic Identification systems or AIS. AIS is a system where each vessel, and certain navigation aids can transmit vessel details automatically via VHF, other vessels that have AIS capability are then able to display this information on an electronic navigation plotter.
