I've got an Eastbay 47 with four Furuno MFD12 displays (upper and lower helm stations). We're not the first owners of the boat so I don't have any rationale for what/why past stuff was installed. Overall most of it seems to be working reasonably well.
I'm looking to add an Airmar 220WX sensor for wind/weather data.
Right now there's already a Furuno PG-700 and an Airmar H2183 installed. Along with a GP-320B (gps).
In the process of doing this I'll have the chance to clean things up a bit, where it would be useful.
The PG-700 is mounted in the starboard berth, the H2183 is mounted high on the mast. I get that the PG-700 needs to be far from any other metal (like the two big C-12 engines).
I've never looked into it fully, but there have been situations in the past where the boat's orientation didn't match what was being shown on the chartplotters. As in, physically pointed one direction, while the plotter shows something else. Likewise some rare occasions underway where it'd show the boat moving in one direction, but the hull pointed in another. Not just a degree or two, that I could understand based on wind or current conditions. This was more like a good 30 deg. off angle.
In looking at the docs for all these it doesn't appear there's enough overlap to eliminate anything if I add the 220WX. Am I correct here?
What I haven't yet determined is whether the MFD12's will accept GPS from something other than their own GP-320 unit. If so I could potentially replace that with the 220WX.
Or not? Would the 220WX provide 'as effective' a source as the GP-320B?
