More About ballast
Long ago, sailors used rocks for ballast. They would put them in the bottom of their boats. This helped the boats stay safe on the sea. Today, boats still use ballast, but they can use water too.
Ballast is important for many boats. It helps them stay steady when the waves are big. This keeps the people on the boat safe. It also helps the boat move fast and smooth.
In the future, boats may use new ways for ballast. They might use special tanks that can fill with air or water. This could help boats be even safer and faster!
