    Dave:

    This is much more than I expected - thank you!
    I will study your material in detail, and I am looking forward to do that.

    But: How in the world did you find all this?

    I haven't been able to track down the Annales Hydrographique 1892 yet to read the original Fave article. 1891, yes. 1893, yes. 1894, yes (and has an article titled, "Ephemerides graphiques donnant les coordonnees des astres pour les usages de la navigation" par M. L. Fave!) 1892, for some reason, non.

    There is, however, an article in Comptes Rendus (118(1894):24-27)by Fave and l'Isle in the Correspondance section titled, "NAVIGATION, - Determaination graphique du point a la mer. Note de MM. Louis Fave and Rollet de l'Isle, presentee par M. bouquet de la Grye." This is available online and I found it among the clearest explantions.

    Also available online in English is, "A graphic method of determining a ship's geographic position" by William Allingham in The Nautical Magazine, July 1892, Vol LXI, No VII. He describes the 1892 Annales article.

    (Google books)

    Also attached is an excel spreadsheet which draws a Fave diagram. Enter numbers in the green boxes, and it calculates and plots. Rough, but it is what it is.
