The boat over the horizon?

Actually?

This is basic stuff

You can bring the boat back into view with binoculars or a telescope, proving it isn’t the curve of the earth but merely the law of perspective

Bringing the boat clearly back into view with optical zoom proves it’s not curve

And your Coriolis effect piece DOESNT EXPLAIN IT

Earth spins 1000mph at the equator

Planes and helicopters do not account for this the same way they claim to account for the spin for speeding bullets
