I searched and found YakBitz. There are several models, but I don't see NMEA 2000. They have USB only, 1,2,and 3 port one way NMEA 0183, and 3 port bidirectional NMEA 0183. If the is NMEA 2000, I have not found it.
I will be coastal sailing the Florida Gulf Coast out of the Crystal River area from St. Petersburg to Panama Beach. I'm working on a Watkins 25 for the task.
So I think that a VHF with built in AIS receiver and GPS with a wifi bridge is my best option. Now my choice is NMEA 0183 or 2000...either the Standard Horizon GX 2200 or the Simrad RS35. I'll have to ponder.
