Quite a lot of users are always interesting in something. And how many of them can crack the method open?
It is sort of unfair load to expect (e.g., in this case) OpenCPN developers to not just write the code (for free) but also crack open methods intentionally designed by greedy manufacturers to limit access to their vastly overpriced products to third party / open source / hobbyist players.
Otherwise yes. You want that Navionics thing talking and a plain router pretending to be a Ray plotter of the desired type. The router can be looked up with a wireshark-like tool and then you see what happens. maybe you get some clues, or maybe you get nothing.
Or else ... connect anything else to that Ray plotter and see what happens when we send it a WPL from OpenCPN.
If I have heaps of time later this week, I may have a look at the story and see if I can get any clues on linking the talker with a fake Raymarine receiver (this is with my wifi router acting as if).
Which Ray plotters use the new method? Maybe, in the end, it is just a plain IP talker/listener thing?
Where can I download that Navionics thingy that does the talking?
