Re: Dipping a Light
Is this another term for establish distance off a known object?
I learned these formula:
If you are working in feet:
d=1.17 x √height of object(ft) + 1.17 x √height of eye(ft)
d=2.1 x √height of object(m) + 2.1 x √height of eye(m)
(d = distance off in nautical miles)
You have to take tides into account where they apply.
