Sadly, flat-earth believers will then claim that the ships aren’t being obscured by the curvature of the earth - rather, supposedly, it’s just that one needs to use a lens to zoom in due to the vanishing point: http://www.ign.com/boards/threads/evidence-for-the-flat-earth-ships-do-not-disappear-over-the-horizon.454885852/ http://www.ign.com/boards/threads/evidence-for-the-flat-eart... Of course, it would be easy to test that theory: keep magnifying as the ship sails away, and if the ship is still appears to sink, then the vanishing point explanation is a non sequitur.
