A few weeks ago a friend and I were talking over a couple of beers about boats---no big surprise there. What was surprising was his confusion about a pair of familiar terms that have been a part of boating for years---namely NMEA 0183 and NMEA 2000. Maybe it's understandable since this guy’s a fisherman and not an electronics geek like some of us. He's probably a lot like most boaters who just want to know that things on their boats work as advertised. But for anyone who wants to know a bit more . . .
