Do ships curve over oceans off a ball earth where they can be 180 degrees upside down from where they started?

Ships travel thousands of miles on the ocean. Where/when does water curve?  downward dip?  Where's the bulge?  Where's the different directional flow?  Shouldn't the sky curve with the earth especially at a distance where we should see more of the bottom of clouds from far away but don’t?
