Light has nothing to do with its weight. It weighs the same in moonlight as it does in sunlight.
The Cargo must weigh less than the ship, and although heavy, ships are less dense than water.
No - more on Earth - in orbit you're weightless.
depends on the ship
Ships come in different sizes, and all sizes have different weights. The only sure thing is that they will weigh less than the amount of water they displace.
7 foot cargo ship probaby dosent weigh over 5000 lbs.
Yes, but not much. A ship is more buoyant in seawater, and thus less of the hull is in the water (thus less resistance).
