    George 
    There is a description of these bearings in Bowditch Vol 1 (my copy is 1984)
    in the Piloting section para 1012 (circa page 301) and a more detailed
    example in Vol 2 Chap 5 Distance \calculations,in my copy (1981)this is on
    page 472. 
    I can send copies if you are interested.
