Well I have to say I'm not sure how they could be used as a moving map.
Wouldn't they need to be vector graphics with the some reference?

No, raster graphics are plenty fine for moving maps. Sure, there
are some disadvantages, but since the sectional charts seem to be
maintained in hard copy, I don't expect much beyond raster
graphics soon.


Must be a ton of work to maintain and update them.


('course if you want to make your own vector graphics, the data is
available.)

Or is it possible to create geo references and plot courses and
positions?

They're already GeoTIFFs.


There's the magic word. There are plenty of programs and libraries (of
the software kind) for manipulating these files. If you had mentioned
that they were geoTiffs already I must have missed it.
