Answer:
The distance to the horizon on the ocean is a function of the height of the observation point. In general (and with thanks to Pythagoras) it is:
d=(h(D+h))0.5 where
If the reference point and an object are both on the horizon then the angular distance to the object, relative to the reference point is simply the angle formed between the two rays from the observer to object and to the reference point. If either the object or reference point (or both) are not in the plane of the horizon then the appropriate rays are the projections of the rays from the observer onto the plane containing the horizon.
The distance to the horizon, d kilometres, is related to the height above mean sea level, h metres, by the approximate formula: d = 3.57*sqrt(h).

The sun and ocean met on the horizon.
To get an "approximate" distance to the oceanic horizon from a particular observation point, take the square root of the height of the observation point, add 22.5%, and that will give you the distance in statute miles. For example, if your eyes were 6 feet off the ground, and you stood atop a 50' tower, your observation point would be 56'. The square root of 56' is 7.48. Add 22.5% of 7.48 (1.68) to 7.48 and you have 9.16 statute miles from your eyes to the horizon.
Horizon d is the point at which the observer's line of sight meets the horizon, creating a horizontal line separating the sky from the earth. It signifies the boundary where the sky appears to meet the ground or sea in the distance.
A vanishing point is a point on the horizon line to which parallel lines converge in a perspective drawing or painting. It creates the illusion of depth and distance in two-dimensional art by mimicking how objects appear smaller as they recede into the distance.
At sea level, the horizon appears to be the point where the sky seems to meet the ocean. This is due to the curvature of the Earth, which creates the illusion of a flat line separating the sky and the sea.

In a small boat, it keeps the boat on a straight line. The fixed point on the horizon does not move. The boat does. If the boat moves toward a fixed point on the horizon, it is moving in a straight line. On any watercraft, watching the horizon also helps to prevent the visual disturbances that cause seasickness.
The appearance of a flat horizon when viewed from a distance is caused by the curvature of the Earth.
The horizon acts as a point of reference for our perception of distance and spatial relationships. It helps to create the illusion of depth in a two-dimensional space and guides our understanding of the relative size and position of objects in a scene. By positioning elements with respect to the horizon line, artists and photographers can manipulate perspective to convey scale and distance effectively.
