So Mark,
How is the "qual card" process working out?? with all that you and everyone else have learned I am pretty sure that you have tried made it easy for those whom have never served on submarines to understand, the school of the boats on Active duty are pretty detailed and those attending had gone through Basic Enlisted Submarine School (BESS) and had an idea of how things were supposed to work.
This school of the boat was taught for those whom never served on the boats and made you realize how equipment worked and how to research the technical manuals so you could find out what your boat(s) actually used to do and not how someone "modified" them to make it look like they were still in service.
One day I will try to visit all of the museum boats, I cannot right now due to being on Active duy and not having the funding to do so
