Gary, this video puts an end to the flat earth theory.
The boat is sinking, bottom first. If the earth is flat, the boat would just shrink in size, disagree?
If you question the video, you can easily try this experiment in a large body of water, lake, or a calm day at sea.
Proves concave earth also, since in a concave earth, you will be always sinking from a point, while a convex earth, the the boat would be rising.
