I understand that with 5 foot height of eye I have a visual horizon of about 2.6 miles.
Height of eye calculator
If I mount an AIS antenna on the stern rail - guess 4 feet and a ship has its antenna at 60 feet do I have a horizon of just over 9 miles or does AIS follow the earth's (water's) curveture and have a greater range? If so what sort of range and if I swap my masthead (VHF) antenna into the AIS would I greatly increase the range?
