Because the H.L. Hunley was made of iron and was submerged for over a hundred years, rust had formed all over the submarine. However, to prevent more rust from forming, the conservators choose to keep the H.L. Hunley submerged in a water tank, instead of exposing it to the oxygen-rich air, until a full conservation plan could be created.
The inrush of water caused the bow of the submarine to sink to the seabed 150 ft (46 m) below the surface. How the outer door (bow cap) to Tube 5 became open to the sea is unknown: Woods maintained that not more than 10 minutes before he opened the tube all the indicators were at "Shut". [3] An indicator buoy was released and smoke candle fired.
