    Re: Bowditch sightreduction table (Ageton?)

    You are correct. American Practical Navigator ("Bowditch"), Volume II, 
    1981 edition, contains Table 35, "The Ageton Method". There are also 
    instructions and a sight reduction example.
    
    In those days there were 2 volumes. The main book was Volume I (1984), 
    1414 pages. Volume II (1981), was "useful tables – calculations – 
    glossary of marine navigation", 961 pages.
    
    Of course the "real" Ageton Method was published by itself as HO 
    Publication 211. There are always several on eBay:

    Several variants on Ageton have been published. One was by Davies (?), 
    which I own, and there is also the S-Table by Pepperday, currently sold 
    by Celestaire.
