Ballast. River cobbles of all different shapes were stored in the ship''s hold to enhance stability. Wooden sailing vessels were inherently buoyant, and tall masts made them extremely top-heavy. Ballast stones were added or removed as the weight of cargo, supplies, or ordnance changed. Anchors and extra cannon were also sometimes used as ballast.

The finding of ballast stones only proved that there was indeed a vessel that lost its ballast at that location. Nothing more. Once the ships guts were spilled, the ship, itself, could easily be shifted to '' god knows where'', along the ocean floor, due to strong currents, hurricanes and hundreds of years of time.

On one of their first dives, in 13 feet of water off Emanuel Point near the old town center, the team found a ballast heap, a pile of stones carried inside a hull to control a ship’s stability. The fluke of a 10-foot-long wrought-iron anchor stuck out from the sandy seafloor nearby, a promising find when archaeologists dated it to the 16th century.

Ballast stones made ships more stable under sail and reduced the likelihood of capsizing by lowering the vessel''s center of gravity. When heavy cargos were loaded, ballast was deposited on shore. In many colonial American ports, laws were passed to prevent ballast from being dumped into the harbor to prevent filling the harbor and hindering navigation.

No, ballast stones were used to keep ships weighted down, which helped to stabilize them as they moved across seas both calm and rough. Once a ship reached Savannah – which began as a British settlement in 1733 – its crew would dump its rocky cargo and replace its relatively uneconomic value with goods grown in Georgia, such as rice, cotton, and indigo.
