    Re: New discussion thread topics?

    Kieran,
    I also tried to have discussions about terrestrial nav. techniques in the
    past but the threads peter out fast.Although what I was discussing had more
    to do with map reading and useing a lensatic compass and clinameter while
    your discussion topics were celestial in nature.I found them interesting and
    informative.My glass reflective AH I built stems from your topic of useing
    tea and such in an AH.That was a damn interesting thread topic.So,at least
    some good came of it.
    I know nothing about the technique you state below to determine magnetic
    variation.It sounds interesting.I would like to learn and would benefit by a
    discussion on the matter.I would like it if you or someone could start by
    explaining how one would use the instruments and tables to accomplish
    this.Is it similar to finding the compass error useing amplitudes?One
    doesn't need a sextant to do that.Start with the basics and we'll go from
    there.This is what I joined the list for!To be exposed to and learn new
    ideas.
    The subject of the polynesian accomplishments,I believe,would be a great
    topic to discuss.I don't know much about the subject but would be willing to
    read about it onlist.
    I've noticed lately some list members aren't posting.Is it no interest in
    the subject?Boredom with the subject thread?Are they busy doing other
    things?Some of the items discussed lately were interesting to a few of us
    but had no bearing on navigation per say.
    Could you start your the topic of Mag. Var.?

    Doug,
    I have tried to get interest going since joining the list in terrestrial
    navigation eg use of sextants, artificial horizons and lunar distance
    observations  on land. It has often been a very lonely occupation except for
    the reliable enthusiasm of George Huxtable in all things navigational and
    astronomic.
    
    One thing of particular interest to me that has never even raised a murmur
    on the list is the use of sextants, compasses and amplitude tables to
    determine mag var. 19th Century explorers journals in Australia at least
    were full of this calculation which was interesting  and exacting. Norie,
    Raper et all spent some time on it and it is relevant today.
    
    On the list - silence.
    
    In relation to the Polynesian navigators there have been some great books
    written.
    
    Regards

    All,looking back over the archives I've noticed some areas of the art and
    science of navigation haven't been discussed by the group at all.
    1. Emergency or lifeboat Navigation
    2. Traditional native ocean or terrestrial navigation
    3. Space navigation
    4. Subsurface navigation
    Is there any interest in the above topics?
    Are there other topics that would interest listmembers?
