Dip Short in Celestial Navigation

For those that practice Celestial Navigation in Coastal, Inland or locations where a proper sea horizon can't be obtained - a correction can be made to compensate for that shortfall - it is call Dip Short, for when the distance to a natural sea horizon is shorter. Of course this won't be of much use other than to practice obtaining your sights because in those locations you really ought to know where you are anyway through other means.

My source for this is John Karl's Celestial Navigation in the GPS Age.

The simple formula is...

DipShort = 0.415767 x d + 0.565786 x h / d, where d is distance in nm and h is height in feet
