Metallic Rectangle over the Ocean

I can't zoom in any further, but with my eyes, I can see it, it's a sphere.

This video lasts for about seven minutes. I'm just going to roll it, and
let you determine what it is.

Taken over the ocean, you can see what looks like a metallic rectangle.

There is also a sailboat in the view.

I zoomed in on it to get a better view.
