    Hi ALL
    
    With all due respect I think we are splitting hairs  and thus starting him
    off on the wrong foot.. If he is just starting out he will be lucky if his
    early  plots are within 4-5 NM of true position. After he becomes an
    "expert" in taking /plotting sights he will be  
    Pleased ..or should be...if he is within about 1 NM...(and that's with a
    very good time keeper at his side)
    IFH.

    Bill,
    
    Of course. 1 sec of time = 15" =0'2.
    (Same accuracy as a good sextant
    measurement).
