You wouldn't ever expect to see the curvature of the earth under these circumstances. The earth is so large compared to a man. At sea, in any direction you care to look, the visible horizon is always at the same distance away. This is why the horizon will always look like a flat line at sea. Sure, you can climb a mast and look from there, but you will still see the same thing. Trust me, I've had to do it countless times. There are other ways to verify that the earth is a sphere, but looking at the horizon won't get you very far. Even looking at a another ship coming towards you, or going away from you can be difficult. The atmosphere can cause the light to bend and deceive your eye. This is especially evident at sea because off all the moisture in the air for obvious reasons. A radar is a little better tool for observing the effect of another ship coming up over the horizon of a spherical earth, but even then the microwave energy can also bend a little because it just like light, but of a lower electromagnetic frequency. You can see some of the effect, for sure, if you carefully observe the target echo on the radar, but it is still difficult to see even if you know exactly what you are looking for. Even the radar on an aircraft at 42000 feet looking down on the earth would only see a difference in distance between a flat earth target and a spherical earth target of about 0.1%. There are other ways to verify the spherical earth paradigm. Experiments have been done for 1000's of years but the results still aren't believed by some. Let the struggle continue.
