Aship's hold orcargo hold is a space for carryingcargo in a ship orairplanecompartment.
Cargo in holds may be either packaged in crates, bales, etc., or unpackaged (bulk cargo). Access to holds is by a large hatch at the top. Ships have had holds for centuries; an alternative way to carry cargo is in standardizedshipping containers, which may be loaded into appropriate holds or carried on deck.[1][2]
Holds in olderships were below theorlop deck, the lower part of the interior of a ship'shull, especially when considered as storage space, as for cargo. In later merchant vessels it extended up through the decks to the underside of the weather deck.
Some ships have built incranes and can load and unload their own cargo. Other ships must havedock side cranes organtry cranes to load and unload.[3]
Acargo hatch ordeck hatch orhatchway is type ofdoor used on ships and boats to cover the opening to the cargo hold or other lower part of the ship. To make the cargo hold waterproof, most cargo holds have cargo hatch. This can be a waterproof door, like atrap door with hinges or a cover that is placed on top of the cargo hold opening, covered and held down with atarp or a latching system. Cargo hatch can also be flexible and roll up on to a pole. A small cargo hatch to a small storage locker is called aLazarette. Should a cargo hatch fail in a storm, the ship is at risk of sinking, such that has happened onbulk carrier hatches. Some ships that sank due to cargo hatch failure:MV Derbyshire,MV Christinaki,Bark Marques,SS Henry Steinbrenner,SS El Faro,SS Marine Electric, and theSS Edmund Fitzgerald. Most cargo hatches have acoaming, a raised edge around the hatch, to help keep out water. The termbatten down the hatches is used prepare the ship for bad weather. This may included securing cargo hatch covers with woodenbattens, to prevent water from entering from any angle. The term cargo hatch can also be a used for any deck opening leading to the cargo holds.Aircraft andspacecraft may also use the term for their cargo doors.[4]
