    Re: Dip short calculations across a small lake
    From: Josh Paterson
    Date: 2015 Oct 14, 18:57 -0700

    The equation in the 1958 Bowditch for Table 22, (Dip of the Sea Short of the Horizon) is

    D = 0.4156d+0.5658*h/d

    where D is dip in minutes, d is the distance to the obstruction in nautical miles, and h is the height of the observer above sea level in feet.
