Ballast Ballast is removable or permanently installed weight in an aircraft used to bring the center of gravity into the allowable range. Center-of-Gravity Limits Center of gravity (CG) limits are specified longitudinal (forward and aft) and/or lateral (left and right) limits within which the aircraft's center of gravity must be located during ...
The advantage of water ballast is that the tanks can be emptied, reducing draft or the weight of the boat (e.g. for transport on ground) and water added back in (in small boats, simply by opening up the valves and letting the water flow in) after the boat is launched or cargo unloaded.
In most racing series, cars have a minimum weight. Often, the actual weight of the car is lower, so ballast is used to bring it up to the minimum. The advantage is that the ballast can be positioned to affect the car's handling by changing its weight distribution. This is near-universal in Formula 1. It is also common in other racing series ...

Shipboard stability computer programs can be used to calculate a vessel's displacement. The process of determining a vessel's displacement begins with measuring its draft. [3] This is accomplished by means of its "draft marks". A merchant vessel has three matching sets: one mark each on the port and starboard sides forward, midships, and astern ...
7 pounds of ballast stopped new track records in 2022, 2023. ... but more weight, too. Whether the cars will come out of that update faster remains to be seen. Some drivers argue that with the ...
Loadline displacement – The weight or mass of the ship loaded to the load line or plimsoll mark. Deadweight tonnage (DWT) is a measure of how much weight a ship can carry. [1] [2] [3] It is the sum of the weights of cargo, fuel, fresh water, ballast water, provisions, passengers, and crew. [1]
The "Operating empty weight" (OEW) is the sum of the empty weight and the crew plus their baggage. Standard items include all structural modification or configuration orders that may have altered the MEW, including all fluids necessary for operation such as engine oil , engine coolant , water , hydraulic fluid and unusable fuel .
