when it goes over the horizon then zoom in with your camera

Oh, yeah, sorry.

I forgot to add that bit

But yeah, I can do exactly that, and no ship

and you can bring it back, just because it goes over the horizon its actually just going out of your limited view

we don't have limited view

no, you will see a ship

your a lying to yourself to think otherwise

people have done it, you can look online

...I'm not lying

I've done it myself :v

I can bring up a video right now showing you can see the ship with the camera but not the naked eye

because its too far away

the ship is blocked by the curve of the earth

you know how a long hallway creates an artificial horizon

no, that isn't the curve

What is it then?

that is perspective blocking you

...what

please explain

If it's flat water

its flat water and the boat is actually on the flat water

then where is the hull?

there is some distortion on any water

there is air vapor that makes it harder to see the more you look thru it

The water is blocking the ship, not the air

it gets far enough way with all of that air vapor, you think its part of the large mass of water but its just vapor

uhm...

its water vapor making the illusion that its not flat water

you do a side view or bring a camera to zoom in, it will get closer

and if you get a more powerful camera, you can bring it right back into focus

You can bring it into focus

it hasn't gone over any curve

but you can't see the whole thing

focus != seeing the whole object

you can see the whole thing unless its too far away and the vapor is too much

please, explain this water vapor thing more

depends on the angle your viewing it

water vapor causes some refraction
