Question

24. The distance of the horizon at soa varies as the square root of the height of the eye above sea level. When the
distance is 14.4 km, the height of the eye is 18 meters. Find, in kilometers, the distance when the height of the eye is
8 meters.
(a) 4.8 km
(b) 7.2 km
(c) 9.6 km
(d) 12 km
​

Answer 1

Answer:

9.6 km this the answer of the question

Answer 2

Have you ever been out on a leisurely cruise and suddenly wondered, “How far it is to the horizon?” Or maybe your destination is a port that has a lighthouse and you wonder “How far away will I be when I see the lighthouse?” (Well, you’re in luck, even if you are a sick unit that thinks of these sorts of things – so are we.) We have the answer!

We have the answer!Of course you can find tables that do the calculation for you in numerous navigation books, almost every book that talks about passagemaking, the Coast Pilot, almanacs, etc. But what if you didn’t have any of these references onboard? How could you calculate the distance to the horizon or the “distance off” if you know the height of an object?

How could you calculate the distance to the horizon or the “distance off” if you know the height of an object?It’s simple, really. If you want to know the distance to the horizon you simply have to know your height of eye. That is the distance that your eyes are off the surface of the water.

Of course, if you were in a jon boat you probably wouldn’t care how far the horizon was.

If you are on the tuna tower of a sport fishing boat you may be 15, 20, 25 feet above the surface of the water.
