If I am in a harbor with hundreds pf markers showing on my screen, they don't confuse me unduly. I look at the ones closest to me. If the radar
shows hundreds of returns, I'd look at the ones important to me for what purpose I am using it.
has a mode where I can have it show only markers that are visible from my location. Or it can show only the lighted markers.
IF, I am seeing all that information, it is also telling me something. It tells me I am in a crowed location and I should be paying attention. For radar, maybe it's warning me that there is some kind of function going on the has loads of boats milling around in a particular area.
For AIS targets it should be the same thing. If I see hundreds of targets, that tells me something valuable. I look at the ones close to me. Then the software should have filters. Only show a dot for ones that don't concern me. Only evaluate the ones for collision if they are within a certain range/speed.
I think the transmitter should ALWAYS be on while underway. Only time it should be off would be in a slip. The software and operator should be responsible for weeding out the ones that don't matter and reducing the data down to a useful volume.
