Ballast is used in ships to provide moment to resist the lateral forces on the hull. Insufficiently ballasted boats tend to tip or heel excessively in high winds. … If a sailing vessel needs to voyage without cargo, then ballast of little or no value will be loaded to keep the vessel upright.

What is a ballasted hull?

Sailboat ballast is a weight carried either in the sailboat keel or hull, typically made of lead, iron, or cement, which acts as a counterweight to the wind’s force on the sails’ force, providing righting moment by lowering the center of gravity.

Do all boats have a ballast?

While there are both live ballasts and high-density ballasts, the one we’ll focus on for this article is the water ballast. Sailboats and other smaller vessels tend to come outfitted with this ballast type. A water ballast gets installed in such a way that its vertical center of gravity makes the boat more stable.
