ABSTRACT:
A ship hatch cover of lightweight, water impervious sheet material covers the hatch of a ship to permit loading of bulk materials during inclement weather while protecting the cargo from potential damage or spoiling from rainwater or other contaminants. The hatch cover includes a frame or superstructure for spanning the open portion of a ship's hatch. A lightweight, flexible, water impervious sheet material is stretched over the frame to prevent any moisture or other contaminants from entering the ship's hold while the ship cover is in place. A plurality of separately accessible ports or openings permit even distribution of a particulate or fluent cargo, such as potash or agricultural products.
