When AIS-reporting vessels are received, a tabular list of the currently received vessels can be displayed with the menu choice View->Vessels. Each vessel is listed by its MMSI (Maritime Mobile Station Identifier), but also reports its latitude, longitude, speed and direction of travel, the name of the vessel, the vessel type, and the APRS symbol inferred from the type of vessel.
Vessels will also appear on the YAAC map and station list, labeled by their MMSI with the vessel name as their alias (tactical name).
