    one would do that"
    
    Scott, you replied:
    "This is just NOT TRUE.  You actually might be surprised how much room
    submarine sailors have for their personal belongings when compared to the
    actual space consumed by HO229.  I grant it's not a lot but more than your
    claim above.  They actually have significantly more room than what is
    required to store HO229.  Clearly, HO229 may take up a lot of room on your
    small sailboat but on a ship or submarine there is enough room to carry all
    the paper publications and charts that a submarine might need for any
    voyage.  Have you ever been on a nuclear powered submarine?  Somehow I doubt
    it."
    
    I have been aboard a nuclear submarine (when I was a kid, as a guest of a
    friend's dad), and there's plenty of spare space for sight reduction tables,
    even on an attack sub. Of course, space is still something that you don't
    want to waste, so to me it would make sense to teach the tables in the
    Nautical Almanac, rather than HO229, for that very improbable emergency
     --but definitely possible emergency-- where you need to navigate by sextant
    and stars.
    
    Hey, I've got a question regarding naval practice with respect to celestial
    navigation: when are they required to carry the almanac for the following
    year? A nuclear sub can remain at sea for a very long time and in war-time,
    it wouldn't be too hard to imagine staying away so long that you run past
    December 31st. Is there a rule?
    
    And you added:
    "I believe I did include calculators but..."
    
    Yes, you did. 'Nuff said.
