    That AIS target screen reminds me of all the boats that have improperly programmed AIS transponders. The USCG has a handy Encoding Guide https://www.navcen.uscg.gov/pdf/AIS/AISGuide.pdf. The most obvious is the entry for “S/Y ANGEL”.
    Names should not include vessel type precursors, e.g. F/V, M/V, MV, OSV, P/V, REC, S/V, T/B; except public vessels, e.g. CG, CBP, USN, LAPD, NYFD, WSF. Because AIS has specific field for vessel type including it in the name is not necessary. It’s up to the client/receiver display to properly distinguish the targets with labels, flags, colors or other distinguishing marks.

    Remove those precursors folks. Did I see a “M/V GIZMO” the last time I was in Camden? 😉

  2. Guilty as charged, Kai, but let’s discuss.

    First of all, I’ve yet to hear of the Coast Guard asking any M/V, S/Y, F/V etc. to clean up its AIS name, and it wouldn’t be hard to do. One thing I’m doing by voluntarily using a Class B AIS is to make my vessel and personal contact info easily available to the authorities, and I’m happy to do so as I think it can help them keep things safe and orderly.

    Second, I think that having S/Y, F/V etc. in vessel names actually helps situational awareness, as vessel names are usually easier to see than the other details (which do of course include types like sailing, pleasure, fishing etc.). Then again some displays, like Raymarine’s, can optionally use target icons that reference the Vessel Type, though I don’t think that’s allowed on type approved displays.

    I don’t have such ambivalence about any other aspect of the encoding guide you linked to, which, incidentally, seems pretty strongly aimed at commercial shipping using Class A AIS. And it’s great that valuable Class A data points like Destination and Navigation Status are accurate for many more vessels than they used to be.

    All that said, “M/V Gizmo” may become “Gizmo” this winter 😉

      I think it’s great you transmit AIS. Thanks to everyone that does! Slightly misconfigured AIS is way better than no AIS at all! I appreciate AIS enough that I’m a mobile AIS to internet relay station for AIS Hub, Marine Traffic and others.

      I found a tool https://www.navcen.uscg.gov/aisSearch/index.php that will allow you to search AIS records and give a notice of errors found in the configuration. Interestingly the tool says a value of 0 for antenna position is incorrect. I’ll have to investigate if it’s assumption of a NULL value instead of an actual 0 value. What’s one to do if the antenna is mounted on the stern quarter?

      If I’m making a DSC transmission to Angel and wish to search in a long alphabetical list of AIS targets I do not necessarily think to look in the “S” section.

      I’ve seen pilot software like SEAiq use little colored flags to distinguish the moving triangles. I’d like to see vendors spend more effort on making AIS display more useful. B&G/Simrad plotters don’t even have an option to display the name next to the triangle on chart view.

    Hi
    Do you know is it possible to program the following channel as we use in Europe for the motorboat channel. Frequency 155,500 & 155,525.. through software yce08.
    when I want to order one gx6000 from usa.
