OK. If you are buying this stuff, you may like to consider the new Navico (Simrad/B&G/Lowrance) VHF60B which includes a AIS Class B transponder. The SOTDMA class B is still unusual, but I have a couple of options...
You mean one N2K bus for the transducers, right? Navico have a range of wind transducers, wired or wireless, that are native n2K. Did you want wired or not?
The Vesper XB8000 is a good fit, as you could use that for your PC interface, via wifi... However, if you want radar, I'd suggest a 3G or a 4G - but they have to use a physical ethernet cable (2 much data for wifi).
If you'd like to look at a system that has Opencpn, and all this gear, you'd be welcome to look at IT sometime, based at gulf harbour.
