There is a mirage. You can see it clearly at the very end of the video when the birds fly by. Though that doesn't explain why the view of the bottom of the boat is blocked by water.
It's not blocked by water, the atmosphere is causing light to refract and it creates an angled mirror that the ship passes through. The first part to enter and become engulfed by the mirage (a narrow mirroring band that covers the horizon line that reflects the sky) is the bottom of the ship. The area that becomes covered by the mirror zone reflects some of the ship (proportional to the covered area) from directly above it. The ship then gets smaller, the effects of being engulfed, mirrored and shrunk results in the ship eventually disappearing from view.
The water line you see is not the horizon line, the actual horizon line is covered by mirroring from the narrow band mirage. That edge you see is the start of the mirage and it starts just below the actual horizon line where the apparent angular size of objects becomes too shallow.
If you're wondering about objects being blocked by the ground, yes it happens but it depends on the situation. Because of your perspective, if your camera/eye is on the ground/water things like waves and sea swell can have a "ramp-up" effect that can physically obscure the bottoms of objects. A perspective so low to the ground creates such an extreme apparent compression of objects that, combined with the "ramp-up" effect of waves or grass in front of the object, distance to the horizon is greatly reduced such that it becomes a physical line of grass, bumps or waves etc.
The situation changes for more distant objects, they can be affected by atmospheric magnification (looming). A refractive lensing effect where water droplets form a compound magnifying lens and objects apparent sizes are enlarged. Magnified objects have part of the bottom obscured because there is no increase in elevation as their size increases, this is a masking effect on an optically enlarged object.
The curvature in that image is clearly due to the lens -- even the closer objects are distorted.
You can't use a simple photograph to show curvature because you don't know how much of that curvature is due to distortion by the lens
That's not proof we're on a globe, it's a cry for help. Also, that's a lot of fucking garbage they've left on the peak.
Distance to the horizon is solid proof of a flat earth; we see too far with a good zoom lens.

Well, thank you. So, you admit that they are tricking you into thinking that the Earth is flat, when all the science says that it is a globe.
Btw, Sandra is a girl's name. Did you know that?

Let me use anime to explain this:
She looks cute right? No, it's a soldier who's been severely injured in battle and has a festering, gaping wound between his legs. Now you want to go and fuck his open wound like like some kind sick bastard and aggravate his injury?
