This is the distance to the horizon, in kilometres. That's 4.8km for a person of average height standing at sea level and looking out to sea. From five metres higher up, at the top of the beach, the horizon would be almost twice as far away.

Visible distance (in nm) = 1.17 x the square root of the height (in feet) This means, sitting in my sea kayak, the "horizon" is really only about 2 miles away. However, a 50 foot tree on the shore ...

The distance of the visible horizon (>9 NM) is far larger than 24 metres and so, lines "eyes—rock top—horizon" and "sea level" are almost parallel. This means that these rocks have a height of 24 metres as well.
