Ballast
Ballast is material that is used to provide stability to a vehicle or structure. Ballast, other than
cargo, may be placed in a vehicle, often a
ship or the gondola of a
balloon or
airship, to provide
stability. A compartment within a boat, ship,
submarine, or other floating structure that holds water is called a
ballast tank. Water should move in and out from the ballast tank to balance the ship. In a vessel that travels on the water, the ballast will remain below the water level, to counteract the effects of weight above the water level. The ballast may be redistributed in the vessel or disposed of altogether to change its effects on the movement of the vessel.
