    Re: The point of it all
    From: George Huxtable

    Peter Fogg has mentioned "Martin Creamer", though the name he wants is
    actually Marvin. C. Creamer. His achievements (if they can be regarded
    as achievements) in circumnavigating, and making other voyages,
    without instruments are indeed worth discussing on this list. I don't
    recall them being aired here before.
    
    This is part of what Peter wrote-
    
    | An American called Martin Creamer has sailed a yacht around the
    globe
    | without using any navigational instruments. As to when: best clue is
    my
    | memory that the story appeared in the first issue of the magazine
    'Ocean
    | Navigator'. Seventies? He sealed up sextant and timepieces and all
    the rest
    | and stowed them up under the bow ( yes I know - not necessarily the
    part of
    | the boat that gets pounded the least!). Just in case.
    |
    | More than anything else I think it was a mental challenge in slow
    motion. He
    | spent months thinking about what he saw as his biggest problem:
    getting
    | around Cape Horn. The specific problem was how narrow the strait is,
    and the
    | imprecise nature of alternative methods of navigation used. Too far
    north
    | and he risked the traditional hazard of running into the southern
    tip of
    | South America: the complex mess of islands with perverse currents
    and tides
    | swirling around them, the whole swept with catatonic winds, often
    with very
    | deep water right up to the shore. Too far south and not only might
    the
    | weather get even worse but the risk of meeting icebergs became
    exponentially
    | greater. Not that far away is the most northern peninsula of
    Antarctica.
    |
    | How did Creamer do it? The solution for that specific problem was
    simple:
    | shoot for the middle, avoiding all land. It worked out fine. I seem
    to
    | remember that a number of navigational techniques were used during
    this
    | circumnavigation and perhaps this is the point - that nav is not
    about one
    | technique or machine or tradition or necessarily any particular
    other.
    | Rather it is potentially about all of them. The funny thing is that
    Creamer,
    | who proved this in the most convincing way, had a technical
    background.
    
    For his circumnavigation, Creamer left the US late in 1982 and reports
    that he rounded the Horn westbound late in 1983 so presumably returned
    home some time in 1984. He addressed the annual meeting of the
    Institute of Navigation in June 85, showing slides, but the account of
    his talk that I have seen gives frustratingly little information about
    the voyage. Perhaps details had been withheld for his proposed book on
    the journey. Did that book appear, I wonder?  An article "What makes a
    great navigator?" about Creamer appeared in "Navigator" journal, July
    / August 1985, and this, too, is sparse on detail about the
    circumnavigation. There may well have been articles in other
    publications also, about that same time.
    
    Creamer sailed without navigational instruments. No sextant, no clock,
    not even a compass. It's the absence of a compass that is so
    remarkable. How did he cope when the skies, and particularly the
    nights, were overcast?
    
    As for sailing without a clock, he could have no knowwledge of his
    longitude, except by estimating his daily eastward progress through
    the water. That put him back into the days of latitude sailing, where
    a navigator ran down a line of latitude until he reached some land on
    the other side. That was used by mariners for hundreds of years,
    including exploratory voyages, in which mariners had no idea what lay
    ahead (at least Creamer had the advantage of modern mapping). There's
    considerable risk involved in sailing that way, not knowing how close
    you may be to the other side of an ocean, and it calls for great
    alertness and cautionary sailing; perhaps at night heaving-to, or
    shortening sail, or sailing off and on a likely coast ahead.
    Foolhardy, in this safety-conscious era, certainly, but if Creamer and
    his two crew were prepared to take the risk, that was up to them.
    Latitude sailing was no great achievement.
    
    But how did Creamer get his latitudes, without a sextant? He estimated
    heights of the Sun, above the horizon; declination of a star, that was
    near the zenith. He would lie on his back, on deck, and try to
    estimate which star was vertically above. An unlikely procedure on a
    heeling yacht, I would think. For travel through the Drake passage
    round the Horn, aiming to steer a path between the Horn and the ice
    (and presumably hoping to avoid Diego Ramirez, right in the way), he
    estimated latitude from the degree of twilight that was apparent at
    Summer midnight!
    
    He makes rather extravagant claims for the precision of his latitude
    estimates, but these are belied in the account, in "Navigator", of his
    approach to Australia. "But when he turned North off his parallel of
    latitude", we're told, "in search of what he hoped would be Tasmania,
    he and his crew suddenly found themselves closing on the barren,
    hostile shore of the southwest Australian coast, almost 1,000 miles
    west of Tasmania. Creamer had apparently been in the East Australian
    Current". There may be journalistic error in that account, of course.
    We can forgive Creamer that 1,000 mile error in longitude, but what on
    Earth was he doing in that latitude, about 9 degrees or 500 miles
    north of his intended destination?.
    
    So I am not over-impressed with Creamer's navigational achievements,
    and hope his example will never be followed. His bravery is
    unquestioned.
    
    ================
    
    Peter Fogg, always ready to offer advice, gives us the following gem-
    
    |One helpful method he used belongs to celestial navigation. Without
    any
    | instrument. If a zenith body can be found and identified then the
    boat's
    | position is known.
    
    No, it isn't. Not unless you know the time. How do you get that,
    without any instrument? Without the time, all you have is latitude.
    Which negates much of what follows, from Peter.
