AIS

We have been using OpenCPN for over a year. Last year we installed a new ICOM M506 VHF with AIS.  We were unsuccessful getting OpenCPN to receive the AIS PGNs via NMEA 0183.  NMEA 2000 was an option but we do not have a NMEA 2000 backbone (yet).  Solution: a Vesper Marine VB-8000 Class B AIS Transponder.  The VB-8000 makes us visible to anyone with AIS BUT also allows us to see any vessels with AIS -- Class A or B.  AND it integrated seemlessly with OpenCPN.  The VB-8000 has built-in wifi and supports up to five devices or connect it to your boat's wifi router and have unlimited connections.  It also has an anchor watch and man overboard plus an app - WatchMate.  For a thorough review: Panbo: Vesper XB-8000 test, much more than a Class B AIS transponder.

First we installed an AIS antenna.  Another option was a splitter to share the VHF antenna.  A splitter cost a little more than the antenna and in my opinion, was another point of failure.  Make sure the AIS antenna is at least a meter from the VHF antenna.

Next, unpacked the VB-8000.  It comes with a dedicated GPS antenna, power cord that also has wires for NMEA 0183 In/Out connections and an external "Silent Mode" switch, and USB cable.

Install was easy.  Make sure the antenna and GPS are hooked up before connecting to power.  This was a good time to install a Blue Sea Systems ST Glass Fuse Block for the AIS, VHF, two USB chargers and 12V charger.

Connect laptop, phone, tablet, etc. to the VB-8000 wifi.  Launch OpenCPN and configure it (I selected TCP vs. UDP):

Sample screenshot of AIS target:

Contacts that are not a 'threat' are either not shown or appear as 'green'.  Caution contacts appear as yellow and red indicate potential action that needs to be taken to avoid.  Next I may connect our compass via NMEA 0183 to the VB-8000.  Why?  GPS only knows your direction when you are underway.
