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. If you're in a jon boat, that would probably be about three feet (if you are sitting like you should be in a jon boat).

wikiHow article about How to Calculate the Distance to the Horizon. ... The distance calculated is a straight line from your eyes to the horizon. The actual distance you'll travel to get to the horizon will be longer because of surface curvature and (on land) irregularities. Proceed to the next method below for a more...

(Of course, the height of the eye, and consequently the distance to the horizon, is greatly exaggerated in this diagram.) The observer's astronomical horizon is the dashed line through O, perpendicular to the Earth's radius OC.

Solution: Your line of sight to the horizon is tangent to the earth. This creates a right triangle with the horizon at one point (the right angle), the center of the earth at the second point, ... If you’re standing on the beach, your height is about 6 feet, which makes the distance to the horizon almost exactly 3 miles.

Deriving the distance to the horizon; part of an educational resource on astronomy, physics and space ... Imagine you were standing at an elevation of h meters above the ocean and looking out across the water. What is the distance D to the horizon? It can be calculated, if you know the radius R of the Earth.

Estimating distance to horizon ... (Of course, having looked at the diagram, we should realize that the distance we actually want is represented by an arc but the line segment corresponding to d should be close enough for our purposes, especially as the relative scales of R and h have been grossly exaggerated!)
