Thanks Sasha and Paul for your help. Ray Marine does use SeaTalk or SeaTalk 2 as its proprietary connection protocol, however it also supports NMEA. If I were to use ST60 I would probably connect all of the equipment using SeaTalk and use a PC-SeaTalk-NMEA Interface Box for the computer and possibly the autopilot. I am still researching which autopilot makes the most sense. I am also thinking about a radar implementation with NobleTec as an overlay to the GPS/Navigation.
