    Bowditch 1995 Table 18
    From: Bill B
    Date: 2005 Feb 2, 01:24 -0500

    Moving forward with "editors that do not know the subject matter"--or maybe
    it is just me--I would like to look at table 18, "Distance of an Object by
    Two Bearings."
    My premises:
    Bearing is the direction (cardinal angle) between the observer's north and
    the object, true or magnetic.  That being clockwise, 0 to 360 or 0 to
    Relative bearing is the angle between the bow end of the lubberline and the
    object, clockwise, 0 to 359,xxxd (or 0 to 360d, depending on your religion
    Bearing on the Bow is the angle between the bow end of the lubberline and
    the object, clockwise or counterclockwise, from 0-180d.
    The 1995 Bowditch, "Explanation of Navigation Tables" states for table 18:
    "To determine the distance of an object as a vessel on a steady course
    passes it, observe the difference between the course and two bearings of the
    object....Enter the table with the two differences..."
    My example, by the book:
    Course 2d true, object and shoreline to port
    First bearing 295d true, difference 293 d
    Second bearing, 245d true, difference 243d
    Now I go to the table.  Whoops!  No values greater than 160d for entering
    arguments.  I can understand that we want an reasonable difference in angles
    between two LOP's to obtain an useable running fix; but darn, here we have a
    system that only works on the starboard side of the boat!
    Have I, as is most often the case, missed something?
    If not;
    A. How should the above sentences read?
    B. Given the errors already exposed in recent editions of "American
    Practical Navigator," how does the nautical community send a message to the
    editor/publisher that the lapses are unacceptable?
