Ballast weight is the mass of materials – typically water, sand, or metal – added to a vessel, truck, or railcar to ensure stability and proper weight distribution when no paying cargo is on board. In shipping, ballast water is the predominant form: vessels take it on during empty voyages to maintain safe draft and effective propeller immersion. Road carriers use physical ballast on empty runs to comply with axle load regulations and preserve handling characteristics. Unlike revenue cargo, ballast generates no income yet increases fuel consumption and can affect weight-based freight cost calculations.
