noodling around with the SR tables in the Nautical Almanac and in my humble
opinion, they are far too convoluted and complex and therefore does not lend
itself to emergency situations where everyone is stressed out and already
liable to make mistakes."

When I first wrote that post, I typed it with HO211 as a compact method, but
changed it to the NA method thinking that HO211 would sound archaic. If you
could compare 211 with the tables in the almanac, do you think one is
clearly superior for compact tables?

Probably a good choice.

Another issue: since we're talking here strictly about navigation in a dire
emergency, we also need to consider the possibility that the single sextant
aboard the boat has survived, but the three to five men with navigational
knowledge are incapacitated. This gets us back to real lifeboat navigation.
What minimal instructions should be included in the sextant box to get the
vessel to a friendly port under the assumption that no one with proper
training is available? This, of course, is where I would recommend something
like "latitude AND longitude by noon Sun". That technique can be learned in
a day by a "well-motivated" student, and you can cross an ocean with it.
