What is the main purpose of a Hatch Door?

The main purpose of a hatch door is to provide access to cargo holds or lower sections of a ship. This design is crucial for the operation of the ship, as it enables crew members to load and unload cargo, conduct inspections, and perform maintenance in areas that are not easily accessible without such access points.

Hatch doors are typically watertight and play an important role in maintaining the integrity of the vessel while at sea, but their primary function remains focused on accessibility. The ability to safely open and close these doors is vital for the efficient operation of any maritime activity involving cargo transport.
