Yes there is.
No, but the centre of gravity need not be inside the object. Not unless Gravity is not a variable. But it is not possible for an object to not have a center of mass.
To reduce the centre of gravity and improve stability of the vehicle.

Their centre of gravity is as far down as possible. Gravity essentially pulls the yacth upright, even from horizontal sometimes.

Yes, the position of the Metacentre depends on the position of the centre of gravity. If the centre of gravity is above the Metacentre, the ship will be stable. If the centre of gravity is below the Metacentre, the ship will be unstable.
It is a measure of the centre.
It isn't. Gravity can be viewed as emanating from the centre of a body with mass. As the distance increases from the centre then the gravity decreases.
As compared to Earth, you mean? If an object doesn't change its shape, the center of mass doesn't depend on gravity - and the center of gravity hardly does so.
A vehicle is made heavy at its bottom so that to keep it's centre of gravity a s low as possible. A lower center of gravity helps keep it stable, moreover, the base is made wide so that the vertical line passing through the centre of the gravity should not get out of its base during a turn.
gravity is a force by which objects are attracted to the centre of.
Assuming the ball is a perfect sphere of uniform density, and is suspended from a massless string, the centre of gravity is in the centre of the ball.
