    It seems to me one fundamental issue is being ignored -- an offshore
    voyager would have no need to keep his GPS receiver running
    continuously.  Briefly turning it on two or three times a day while
    offshore (perhaps more often while making landfall) in all likelihood
    give more and more accurate navigational information than celestial.
    While I have not traveled to truly undeveloped parts of the world, my
    impression is that AA batteries are pretty widely available.   There are
    very few places in the world that are not touched by at least some of
    modern technology (radios, etc) that require batteries.

    The phrase "right sized" technology is apt here.  I wouldn't condemn all
    technology (eg, I do think I'd want 12 volt electricity on my boat
    despite some hard-core cruisers eschewing even that).  On the other
    hand, fancy, unproven (in the sense of "unreliable," not "untested)
    technology will likely enslave its owners.  The trick is figuring out
    when technology has evolved to a point of reliability where it makes
    life easier rather than harder.  I don't think it's fair to condemn all
    technology with a single example (without specifics) of cruisers
    shackled instead of liberated by their technology.
    
    An excellent example is refrigeration.  Some cruisers condemn
    refrigeration systems as totally unreliable and happily drink their beer
    warm.  On the other hand, I know at least two cruising couples (one who
    have been at it for over five years, the other just starting) who would
    swallow the anchor if they couldn't keep food cold.
    
    I guess we all have our own tradeoff points around willingness to take
    chances with technology (hassle vs benefit).   Big things like engines
    and fiberglass hulls, little things like refrigeration, anchor
    windlasses, and GPSs.
