Any other useful things?
Portland Plotter - after one of my coastal navigation students showed
me one I put away the parallel rules. I still like a Douglas
protractor, but I use the parallel rules as an antique. The Plotter
is my mainstay.
After I demonstrate all 3, almost all of my students opt for the
Portland Plotter.

Portland Plotter? I'll do a search on it.
I hate the parallel rules because they are hard to use with the chart
spread on a pitching cabin floor. Instead I use my hand bearing
compass mounted to aplastic square I can align with north and
perpendicular to the edge of the chart. I have a protractor mounted
to it so I can rotate it about the compass axis. Works for me.
Around here, in most cases, i can ignore the difference between
magnetic north and true north.
I seriously considered the Fujinon 10X50 binocs with internal compass
but decided that I have never wanted to take a bearing on anything
with binocs so bought the ones without the compass. So, I still use
my trusty Suunto hand compass (the kind with the mirror) that has
lasted through many caving and sailing trips.
