Marine Traffic, etc are all AIS sites. Do you mean that they don't show up on the Boatnerd AIS page?cpfan wrote:
Of the boats I follow, on any given day, 25% might be on AIS, started about end of sept. when I noticed it, Because of my log, I can find them on marinetraffic, and or vessel search. or my other search engine. I thought that I just happened to pick, the lucky ones, but it is true, some dont show on ais, and it is not the known dead areas.. then other days they do show up on Ais.
If you are going to monitor ships online, you need to use several sites. On my PC, I use Marine Traffic, Boatnerd, the Seaway pages (map & schedule), and Vessel Finder. There are other pages such as Siitech and Ship Spotting. Even then, there are still blank areas.
You say "not the known dead areas". Can you be more specific?

AIS I do mean B/N ais, (bad habit)
dead spots are too numerous to name, just this morning the Boland and Block were no wheres to be seen, on B/N or M'T, Block is at detour now.....
dead areas, out from Toledo, down the upper lower pen, shore line, of mich, area either side of milwaukee, to name a couple....... I think the boland and block were cancelling each other out..........

P S. some times on M T, I have to go right down to full screen to get a reading. I do so, cause my log tells me where a boat should be.
