I request some accurate information about how far a person standing on the deck of a ship can see in good light and a calm sea.
To hypothesize, let us assume that the person is standing on a ship's deck that is 40 feet above the sea level. Add another 5 feet to the eye level and so he/she is looking out from 45 feet. In that case, how far away will the plain horizon be assuming that there are no mirage or other optical effects to affect the line of vision?
