  • Chart plotter + AIS radio = happiness?

    Hello all -

    I am installing a chart plotter/fish finder on my 19.5 and am thinking that by adding a new AIS capable radio I will better be able to dodge freighters when fishing the Straights. It is my understanding that a new AIS capable radio can be married to a new chart plotter/fish finder so that ships actually show up on the chart. Am I correct? And if so, can I get some brand recommendations?

    Thank you.

    Answer is yes. My STD. Horizon VHF receives AIS transmissions and displays them as small triangles on my Lowrance HDS chart plotter. I am impressed with SH’s customer service as it took some guidance to wire the two together.
    An alternative is an iPhone app which will pick up AIS signals as well as provide data on the signal source. Less than $10 at the App Store.
    The cruise liner QE2 moves only six inches for each gallon of diesel fuel that it burns.

      Welcome aboard, CaptDitty!

      Should work with any modern(ish) chartplotter. As long as you can link the radio and chartplotter, be it direct-wired, or through an NMEA network connection (NMEA 0183 or NMEA 2000).

          Be wary of relying on the AIS apps at sea. The apps depend on shore based stations picking signals up from off shore. While apps are impressive, it's tough to depend on someone's home based receiver station and residential internet in order to have a reliable picture of situational awareness. The best way to get the dependable picture of what and who's out there is by having your own AIS reciever to see what's around in your own proximity, and ideally a transmitter too so that they can see you!

          AIS will connect by NMEA 0183 or 2000 to your network.. 0183 can be tricky indeed. Good to hear SH support was reliable....

            gps chartplotter + ais radio is (IMHO) the next best thing to radar.
