Double Bottom
Double Bottom is a type of hull design used in ships and boats, which consists of two parallel sections of the hull bottom separated by a space. This space is filled with ballast water or other materials to provide stability and strength to the vessel. The double bottom design is used to increase the structural integrity of the ship, making it more resistant to damage and less likely to sink in case of a collision or grounding. It also provides additional protection against oil spills and pollution. Double bottom is a common feature in modern ships and is required by international maritime regulations for certain types of vessels.
