The image in that video is deceptive and you can see how in the following image. Showing an image is easier than explaining how half the boat in the video is actually a mirrored reflection.

Showing an unrelated image of a different ship with different atmospheric conditions does nothing to explain the video I linked.
If you watch the video I linked you can clearly see that the atmospheric conditions are such that no mirroring of the ship is evident where the ship and the water meet, so the bottom of the ship is not obscured by a mirror image of the top part of the ship, rather the bottom of the ship is obscured by water.
It's not fucking unrelated it makes it clear there's a mirror line and the ship in the video also clearly has one. Second point is that once an object passes the vanishing point that's determined by the optics of the eye/camera it becomes obscured from the bottom up due to the angle light enters at. This is perspective and optics and has nothing to do with the earth being a motherfucking ball.
You can watch a ship disappear from the bottom up then zoom in and pull the whole ship back into view. Just because you've got video of a boat doing this at max zoom and the limits of the cameras optics so you can't zoom in any further doesn't somehow by magic mean the ship is falling off a curved surface. The water is fucking flat, it's provably flat fucking stupid cunt.
Of course it's unrelated to the video I linked, you may as well have shown a picture of an orange to argue against my original request to explain away the video.
There is no mirrored image in the video I linked visible. If you're seeing some it's only because you subjectively want it there to convince yourself that the ship is not on the other side of the horizon, as it doesn't suit your agenda.
I'm kinda curious as to how much zoom you think you need to pull the ship back over the horizon??? I should clarify for you that this is purely a rhetorical question, as no amount of zoom is going to magically lift that ship out of the water again as perspective and optics are not the reason you can't see the bottom of the ship, curvature of the Earth on the other hand is.
Watch this video I posted, it explains a lot of how perspective works. --
