A friend and I have been having an ongoing debate for years. We were at a pub on a wharf, watching shipping container ships and cruise ships come into dock, and he posed the question. With no wind, no waves, perfect conditions, could he move the ship at all?
In: Planetary Science
The ship will be in water thus it has to push the water away to move forward.
So it depends on how is the ship shaped like and how deep is it from the surface.
If it is magically just on the surface or is a hovercraft, then it will not need to push any water away thus it can be pushed easily under ideal conditions.
