I built a prototype hub that would allow 0183 and 2000 to
interoperate. The outrageous fee to NMEA for the 2000 docs
and license to implement it made it not viable. If NMEA wants
2000 to succeed then they have to encourage the small operator
rather than pricing them out of the market.

NMEA-2000 isn't new - it was introduced in 2000 (hence the name). It
is not compatible with NMEA-0183, as 2000 uses CAN-Bus which is a
bidirectional multi-point bus (vaguely similar in operation to
SeaTalk, but incompatible with that, too).

There is apparently a considerable licence fee to use NMEA-2000, so
you may see manufacturers going to their own proprietary busses,
rather than using NMEA-2000.
