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.

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.

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.

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.

Most of the ships went in ballast to Savannah and at arrival they dumped their ballast stones along the Savannah River shoreline. This means that ballast stones were arriving in substantial numbers to Savannah in the early 1800’s. The total amount of ballast stones found in the waterfront area today has been estimated to exceed 800.000 tons.

It is therefore possible that the sailing route of the ship extended to the western Mediterranean, the Adriatic, or theoretically even as far north as Normandy or eastern England. The estimated total weight of the stones was about 30 tons, which would have been an adequate ballast weight for a brig of these dimensions.

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.

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.

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.
