Now, you can invoke EA to explain this I guess,
Didn't want to copy your whole post. Recap, you could invoke EA as to why a ship's hull appears to go behind the horizon.
Over my morning coffee, I happened to think about the Bishop's experiment for some reason.
https://wiki.tfes.org/Experimental_Evidence That led me to thinking about this thread and your statement.
Assuming that everything in the WIKI is truthful and accurate, the Bishop experiment would empirically verify that EA bends light less than 20 inches at the water's surface over some 23 miles. That being the case, EA would bend light significantly less than that at the distance of roughly 3 miles that a ship begins to sink below the horizon. This leads to the fact, should empirical evidence be believed, the majority of the 20+ feet of cargo ship hull should be visible at distances in excess of 23 miles to sea.
