    A nautical story

    Sounds good. Without Satnav I doubt you could claim accuracy , but a good story.



    A FASCINATING SHORT SEA STORY

    The passenger steamer SS Warrimoo was quietly knifing its way
    through the waters of the mid-Pacific on its way from Vancouver to
    Australia.

    The navigator had just finished working out a star fix and brought
    the master, Captain John Phillips, the result.

    The Warrimoo's position was LAT 0º 31' N and LON 179 30' W.

    The date was 31 December 1899.

    "Know what this means?" First Mate Payton broke in,

    "We're only a few miles from the intersection of the Equator and the
    International Date Line".

    Captain Phillips was prankish enough to take full advantage of the
    opportunity for achieving the navigational freak of a lifetime.

    He called his navigators to the bridge to check & double check the
    ships position.

    He changed course slightly so as to bear directly on his mark.

    Then he adjusted the engine speed.

    The calm weather & clear night worked in his favour.

    At mid-night the SS Warrimoo lay on the Equator at exactly the point
    where it crossed the International Date Line!

    The consequences of this bizarre position were many:

    The forward part (bow) of the ship was in the Southern Hemisphere &
    in the middle of summer.

    The rear (stern) was in the Northern Hemisphere & in the middle of
    winter.

    The date in the aft part of the ship was 31 December 1899.

    In the bow (forward) part it was 1 January 1900.

    This ship was therefore not only in:

    Two different days,

    Two different months,

    Two different years,

    Two different seasons

    But in two different centuries - all at the same time.

    Sorry to spoil the story a little - but contrary to popular belief, 1899 and 1900 are in the same century. The twentieth century did not begin until 1/1/1901.

    You are right of course. But sometimes I think we need these stories .

    I'll just put the stick in ground, find north with my watch, and count my steps. I'll get there.

    The Warrimoo was 105m in length

    At the equator 1 minute of long/lat is 1850m

    So to straddle a specific point on the equator with a 105m boat
    Requires accuracy to 1.6 seconds of accuracy

    Current considered accuracy of non differential GPS is in the order of
    0.3 seconds of accuracy.

    Sooooooooo, using a few chronometers and sextants (on a moving boat)
    The turn of the century mariners would only need to be 6 times less accurate
    Than an I-phone !!! Feasible perhaps.

    But with current accurate time pieces and $$$ sextants (likely more accurate than the 1899 mode used) about 6 seconds is considered bomb accurate

    I’m guessing at best they may have been in the general vicinity of the intersection at roughly midnight!!!

    While I technically agree with you, does it mean that we should have had the big millennium party on 2000-2001, instead of 1999-2000?

    I think I am repeating a yarn. As Anzac day is approaching I will give my self a leave pass today.

    On HMAS Vampire, Mutiple mishipmen took sexants to mark our possitions every sun rise and sun set. The running joke was were and what we could be eating given thier sightings. I think Malasian was a possiblity while off JB Bob Jervis Bay for you non Naval types

    Yes, and this was widely discussed at the time.
