    Re: Sextant observations in the Chesapeake Bay

    When I was a kid I sometimes used to practice from the beach or from the family boat at anchor, and often had a shore horizon.

    Inman's Tables had a table for dip for a shore horizon based on height of the observer and distance from the shore horizon.  The Admiralty Manual of Navigation addressed it too.  With known distances (which I had for my practice locations) I used a table provided to me by an early mentor which I belive was taken from an old edition of Inman's Tables.
