    Looks like a star overhead problem to me!  On page xxxiii (near the end
    of the grey pages in my commercial version) there is an Index To
    Selected Stars
    Turns out that the declination of Sirius is very near the same as the
    latitude of our destination.  All we need to do is calculate the UT when
    the body passes over the destination and aim the boat at the star.
    So, Lo at destination = GHA Sirius at some UT
    	GHA Sirius = 145d	(rounded - I'm a little short of time)
         (-)SHA Sirius = 259d
    	GHA Aries  = 246d which occurs around 1200 UT
    Then 1200 UT
        +10      ZD (rev)
         0200 ZT at destination
    Certainly before sunrise anywhere in the region.
    This what you had in mind?
