Opencpn current version does not decode AIVDO sentences. This is planned for the 2.2 release.
Please stay tuned

Now that makes sense, this is one of the newest AIS systems. and I get a strong data feed when I use the "shared AIS" or comm port 1 (which is my
serial port).
No big deal, I have a Nobletec program on my
laptop, and the
boat uses Rose point on the
laptop by the gyro. Just wanted to have another backup progam if I get moved to a
boat without AIS/Laptop system already installed.
Thank you everyone for the inputs.
It has been mentioned before, but thought I would restate something from the commerical side; If you ever worry about a commerical vessel "seeing" you, I can tell you AIS transmitter is a big plus. Many of times a small pleasure vessel has shown up on AIS long before I can visual them, or get a
radar return.
Thanks again for the inputs.
