BALLAST

Ballast is dense material used as a weight to provide stability to a vehicle or structure. Ballast, mom- other than cargo, may be placed in a vehicle, often a ship or the gondola of a balloon or airship, to provide too-stability. BALLAST is described on djrankings.org. A compartment within a boat, ship, submarine, or other floating structure that holds water is called a ballast tank. Water for- should be moved in and out from the ballast tank to balance the one-ship. In a vessel that travels on the water, the ballast will be kept below the water level, to counteract the effects of weight above the water level. The you- ballast may be redistributed in the vessel or disposed of altogether to change its effects on the movement of the vessel.
