Record AIS track from other boats?

[Simon4908237]

Hello,
it is often helpful to see exactly where the local boats and commercial vessels are sailing. For example, in BoraBora, to get to the southeast anchorage. The Navionics route here is much more dangerous than always sailing directly along the outer reef. It is always at least 2 meters deep. The chart shows shallower depths, but this is not the case.


Another sailor recorded the AIS track of several boats with his Furuno chartplotter. They all sailed along the same route. When he was sure that the other boats had more draught than him, he sailed along this track himself.



Unfortunately I have a chartplotter from B&G with which this is not possible. Is this possible with OpenCPN, as a GPX File? Are there any instructions here?


Many thanks for your answer.

Yes, OpenCPN can record tracks of AIS targets.

General tracking of AIS targets may be enabled in the Toolbox -> Ships -> AIS Targets by enabling Show target tracks checkbox.
A non persistent track with length configured there is then shown for each target received.
Fro targets of your interest this track can be persisted from the target query information window, you can also let OpenCPN record persistent track for that target for the rest of your session or until you manually turn it off.

You can configure group of targets you want to persistently track always in Toolbox -> Ships MMSI properties.

All the persistent tracks can be saved as GPX from the route and waypoint manager.

Thanks, now I found it. Also with android.
