The options were flat or spherical, now you've gone and complicated things by offering evidence for a concave earth.
That's because of fisheye lens on the camera...
But imagine this, if you are out at sea, and a sailboat comes your way, what do you see first? Whole sailboat, or top of the mast?

Q: If BobLawblaw sees boats "disappear over the curvature" at 5 miles away, then where is the "curve" over the 10 miles from left to right?
(8 inches per mile, times the mileage squared: 8 x (10x10) = 800.20 inches = 66.68 feet)
A: There is no curve, and BobLawblaw is a retarded and hermaphroditic goat-blowing sissy.
