You can choose a necessary part of tutorial in "Portable" folder. Basic information is in the 1-4 parts, most interesting starts from 5.

Yes, Sjizzle tutorials are really the best (although I haven't learn "true" real navigation yet )

You will also find lot of helpful charts/tools in the game and also in Real Nav documentation folder, sun almnah and some more documentation to read.
