Have a read of the document linked above to learn the differences. If you want to cut to the chase, scroll down to the table in pages 22/23 for the listing of what data is shared over each of Ethernet, N2K and N0183. Unfortunately it is in a table format and I can't get it to cut and paste and keep a sensible format, so you will have to look at the document.
Note to self: Don't argue with an idiot. They will only bring you down to their level and beat you with experience....
