    Ben, Great job of showing how all the major MFDs handle the MOB alarm. However in my experience Raymarine, though it recognizes and alarms in the case of a MOB, it is displayed as just another AIS vessel. How are the MOB targets displayed and tracked on the chart plotters?

      Good point. I did get the Axiom 7 to pan all the way to Tamaki Strait and thought I saw the MOB AIS icon (and also thought I got a screenshot) but I need to do both over. Will also check others…when the weather here warms up a little 😉

      Another nice thing about this simulation is that it runs for a while. By contrast, the AIS MOB test function only sends a few messages and thus it’s hard to fully see how an MFD responds.

        Jason, you are right. The Raymarine Axiom handles an AIS MOB message well but it does not show the proper AIS MOB icon on the chart. Disappointing, and hopefully something Ray will fix soon.

    I tried the Vesper XB8000 simulation with Coastal Explorer and TimeZero charting software on a PC, and that works particularly nicely because the programs are also getting their GPS (and more) from the XB. So you are suddenly cruising in the Tamaki Strait with a whole lot of AIS going on, at least on your charting screen.

    To my surprise, CE did not seem to produce an AIS MOB alert in two tries, though it did use the proper AIS MOB icon. TimeZero did everything well.

    And it was about then that I realized I’ve been sending these simulations out via FloatHub to Marine Traffic and AISHub. And when I checked MT, some of these simulated vessels were there. Doh! And apologies to any real Tamaki Straits boaters who may have been momentarily confused.
