Ballast stones, whose weight stabilized empty ships, have been found at various colonial landing sites along the North Carolina coast. Although there are no known records, residents and local historians believe that these stones, found in coastal counties along the shore and under water, were used as ballast in early sailing vessels.

When the ships were reactivated, and fitted with stores and guns, large quantities of ballast was removed. [2] The ballast that was removed would be taken on barges to the ballast pond, a large square pond dug along the sides of a tidal river, and accessed by an opening to the river by which the water flowed in and out of the pond, and by which the barges entered and exited.

The whaling fleet exploded from just twenty ships in 1806 to seventy-eight in 1821. Those seventy-eight ships carried 27,495 tons of oil across the seas to Europe, whereas fifteen years earlier just under 5,000 tons were delivered. And since stones were used to provide ballast when no cargo was on board, plenty of cobbles found their way back here.

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.

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.

Answer (1 of 8): It depends on the specific date, if you are talking about warships or civilian vessels and which country. We are, after all, talking about a period of several thousand years as ‘sailing ship’ in the context of needing ballast would also include galley’s.

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.

Whether the ship was loaded or in ballast is not known, however it would be extremely unusual to undertake such a long voyage in ballast and we can only speculate on the type of cargo. Sailing ships had to load some form of solid ballast when empty for reasons of stability, in this case some 200-250 tons, about 1/3 of cargo capacity would be needed.
