The ship becomes completely blocked physically from view by the earths curvature. It doesn’t bob in and out of view from riding the waves.
Like the North Star doesn’t dim as one travels farther south. But the North Star becomes increasingly lower on the horizon. Then travel far enough south below the equator, the North Star becomes physically blocked from view by the earth’s curvature. The Star didn’t dim out of view. A telescope cannot bring it back into view because it is physically blocked from view by the earth’s curvature. Which is impossible on a flat earth.
The viewing angle on flat earth would never go to zero. It’s mathematically impossible. Much so more for the sun going below the horizon. Night fall is literally the curvature of the earth casting a shadow.
Campanella devises an experiment involving three posts of the same height and a high-powered laser. The idea is to set up three measuring posts over a nearly 4 mile length of equal elevation. Once the laser is activated at the first post, its height can be measured at the other two. If the laser is at eight feet on the first post, then five feet at the second, then it indicates the measuring posts are set upon the Earth's curvature.
In his first attempt, Campanella's laser light spread out too much over the distance, making an accurate measurement impossible. But at the very end of Behind the Curve, Campanella comes up with a similar experiment, this time involving a light instead of a laser. With two holes cut into styrofoam sheets at the same height, Campanella hopes to demonstrate that a light shone through the first hole will appear on a camera behind the second hole, indicating that a light, set at the same height as the holes, travelled straight across the surface of the Flat Earth. But if the light needs to be raised to a different height than the holes, it would indicate a curvature, invalidating the Flat Earth.
Campanella watches when the light is activated at the same height as the holes, but the light can't be seen on the camera screen. "Lift up your light, way above your head," Campanella says. With the compensation made for the curvature of the Earth, the light immediately appears on the camera. "Interesting," Campanella says. "That's interesting." The documentary ends.
The tides last for hours, they do not bob. The bulge caused by the high tides would cause an object to be hidden at far distances.
The typical tidal range in the open ocean is about 0.6 metres (2 feet) (blue and green on the map on the right). Closer to the coast, this range is much greater. Coastal tidal ranges vary globally and can differ anywhere from near zero to over 16 m (52 ft).[3] The exact range depends on the volume of water adjacent to the coast, and the geography of the basin the water sits in. Larger bodies of water have higher ranges, and the geography can act as a funnel amplifying or dispersing the tide.[4] The world's largest tidal range of 16.3 metres (53.5 feet) occurs in Bay of Fundy, Canada,[3][5] a similar range is experienced at Ungava Bay also in Canada[6] and the United Kingdom regularly experiences tidal ranges up to 15 metres (49 feet) between England and Wales in the Bristol Channel.[7]

The longest laser level experiments on a lake that i found was 8 miles away, with multiple light sources. There should be 20 ft of curvature, but the lights were clearly visible.
The Wallace Method
flatearth.ws...
In 1870, Alfred Russel Wallace proved Earth’s curvature in the Bedford level experiment. His method was straightforward & effective and can be easily used in a similar experiment.
Wallace’s method fixes the common issues with similar experiments done by flat-Earthers. They usually fail to control, and even disregard, the effect of atmospheric refraction. Using Wallace’s simple method, we can easily prove Earth is a sphere.

As I said before, I think the spherical attributes, such as earths coordinate system and the celestial coordinate system, come from a curvature of spacetime, rather than 3-dimensional space being curved. This difference is known as intrinsic or extrinsic curve.

Map Projections
Anyone who has done a significant amount of practical navigation around the earth can tell you that there are different ways to represent the earth on a piece of paper, i.e. what we call maps. (There’s a difference between maps and nautical charts that ships use at sea. But that’s beyond the scope of this discussion.)
The are many different approaches to challenge representing a spherical object on a flat plane (i.e. a printed paper map) for use in a practical environment, like for shipboard navigation. The technical name for each of these approaches is called a “map projection”.
Because they represent the spherical earth in a flat plane, all map projections contain some kind of distortion.
For example, the most common map projection used was developed in 1569 by a Flemish cartographer named Gerardus Mercator and is called the “mercator projection.” This map projection is widely used in large part because it depicts compass courses as straight lines.
The mercator projection basically “projects” the spherical earth onto a cylinder and then unrolls the cylinder to lay it flat. This causes increasing distortion as one gets closer to the north and south poles along the top and bottom edges of the map when the whole earth is depicted.. With the mercator projection the shapes stay the same, but the area of the shape increases significantly towards the poles. Because of this distortion, land masses like Greenland and Antarctica appear far larger on these maps than they really are.
Even with this distortion, the mercator projection makes for an incredibly useful map.
The “azimuthal equidistant projection” is another map projection with some interesting properties. This map picks a point on the globe and then spreads the earth out from a sphere to a plane around that point creating a circular map. The distortions with this projection get bigger as the distance from the center of the circle increases. The distortions are pretty severe at the outer edges of the map circle when depicting large areas like the entire planet.

Good gosh.
I was in the Navy. The navy maintains tactical competence, able to get on station as fast as possible and on scheduled, and maintains fuel efficiency by treating the earth like the spherical shape it is.
Let’s fail conservatively. Each contain is about 6 feet in height. The ship pictured looks like the water line to the deck is 3 containers tall. About 18 feet to the water line to the deck. We’ll fail conservative again. The containers on the deck are stacked on three high. Dismissing that the containers are actually stacked about 6 containers high, and ignoring the rather tall control bridge. For this example, the ship is 36 feet above the water line. Ultra conservative failing.
Now. What is the hight of tides, ignoring the ship and beach are essentially in the same tide phase.
"The typical tidal range in the open ocean is about 0.6 metres (2 feet) (blue and green on the map on the right). Closer to the coast, this range is much greater. Coastal tidal ranges vary globally and can differ anywhere from near zero to over 16 m (52 ft).[3] The exact range depends on the volume of water adjacent to the coast, and the geography of the basin the water sits in.

The ship is very much taller above the water line than the typical 2 feet of tide.
And dollars to donut the height of the ship above the water line is greater than the heights of tides of at feet. Which would be 9 six foot tall containers.
So. No, the tides are not “hiding” the ship in the below video.
You tried to uses tides that would be impossible in the flat earth delusion no gravity to explain another item impossible on the flat earth. What a F’n joke.

Two, Doesn’t explain the failing of what the flat earth delusionalist adopted for their map in navigation.
Again. This arrow out of South America doesn’t get you to Antarctica
The direction of relative travel takes you to Africa
Three. Doesn’t explain the need for various map projections.
But it is extrinsically spherical, not intrinsically spherical. You would get the same effect with both.

There is no advantage for treating the world as flat for navigating the world. And the earth is demonstrably physically spherical.

And what does that have to do with…
If you want to create your own delusion of space time. That is your right. But when it comes to reality of traveling the world, mapping the world, building suspension bridge towers, explaining why the North Star is physically blocked from view in the Southern Hemisphere, explaining that night fall is literally the showdown of the earth’s curvature, the strength of earth’s gravity at various geological locations, making weather, it’s practical and accurate to treat the earth as spherical.
Flat earth is the lie.
How does a sun that is always above the flat earth delusion strongly illuminate the bottoms of clouds at sunset in my spherical earth reality

Newtonian and Einsteinian models are not exclusive. I once read that Newton explains how things interact, Einstein explains why. Einstein's physics does not mean there are no spheres, it just explains why those spheres behave the way they do in relation to everything else.

How would you use space time to make the design of a suspension bridge on a spherical earth better than current practices and codes?

Yeah Einstein's physics does not necessarily say there are no intrinsic spheres, but it does say there is the possibility that spheres are extrinsic. This distinction might actually be able to solve some broader discrepancies with the intrinsic sphere assumptions. I'd love to corroborate with others and discuss, especially given some sort of computer engineering experience to be able to model what this distinction would imply.

I couldn't find any sources that refer to actual engineers who build bridges. That guy in your link admits he does not. I've found assumptions both ways, either saying no you don't or yes you do without concrete evidence to support either.
This is why I think the laser level experiments on frozen lakes are the most simple examples that don't involve speculation. Same with long distance photography
