Coverage
The system radio coverage range is similar to other VHF applications
and is dependent on the height of the antenna. The propagation differs
from that of a radar, due to the longer wavelength, so it is possible to
"see" around bends and behind islands if the landmasses are not too
high. A typical value to be expected at sea is 20 nautical miles.
AIS information content

vessels and shore based stations and vessels and Aids to Navigation
