Hold (compartment)

Parts of a ship

Aship's holdorcargo hold is a space for carrying cargo in the ship's compartment.

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 standardized shipping containers, which may be loaded into appropriate holds or carried on deck.^[1][2]

Holds in older ships were below the orlop deck, the lower part of the interior of a ship's hull, 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 in cranes and can load and unload their own cargo. Other ships must have dock side cranes or gantry cranes to load and unload.^[3]

Acargo hatchordeck hatchorhatchway is type of door 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 a trap door with hinges or a cover that is places on top of the cargo hold opening, covered and held down with a tarp 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 a Lazarette. Should a cargo hatch fail in a storm, the ship is at risk of sinking, such that has happened on bulk 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 the SS Edmund Fitzgerald. Most cargo hatches have a coaming, a raised edge around the hatch, to help keep out water. The term batten down the hatches is used prepare the ship for bad weather. This may included securing cargo hatch covers with wooden battens, 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 and spacecraft may also used the term for its cargo doors.^[4]

Basic types:

• Lifting (up to remove)
• Rolling (rolls up on to a pole, trap type)
