You can watch ships drop below the horizon

There's a limit to the angular resolution of the lens of your eye. Get yourself a Nikon P900 camera with telescopic lens and you can zoom right back in to those ships you can no longer see with your naked eye. And to wit, there's a limit to the angular resolution of the lens of the camera too.

you can’t see the North Star in the southern hemisphere

All observational claims are subject to the "law of perspective" which is simple and obvious to understand. You can't see everything, everywhere forever which is what this weak claim suggests. Instead, you can see what is near you but not what is far from you. Look it up if you don't understand.

water spirals counter clockwise in the north, clockwise in the south

No it doesn't. The "Coriolis effect" is a fallacy, a wives tale, 100% debunked. No such phenomenon occurs. The water spiral depends EXCLUSIVELY on the shape and design of the drain holding the water, and/or the momentum given to the water when the drain is opened up.

It flows straight down on the equator, great circle paths fall southerly in the southern hemisphere

This sentence doesn't even make sense.

Sorry, you lose, as all GLOBALISTS lose. Once again, zero science, all you've provided are nothing but fully debunked arguments.

Where's the SCIENCE? Zero scientific proofs of the globe? How can that be? Things that make you go hmmmmmmm?
