A vented hatch cover for a container having an opening defining a hatch and a coaming on the container's exterior surrounding the hatch opening. The cover has an outer shell and an inner shell, each shell having a main body and a flanged portion. The bodies are sized to fit over and enclose the hatch opening. The flanged portions are bonded together and extend radially outwardly from the corresponding bodies to fixedly couple and hold the bodies of the inner and outer shells in a spaced relationship to present an air chamber therebetween. Balsa reinforcement members are spaced apart and fixed between the shells in a radial pattern within the air chamber to provide support to the cover without interfering with the air flow. Air inlets are formed through the flange and body of the inner shell to allow air flow from the container's exterior into the container via the air chamber. A sealing ring extends around the interior surface of the inner shell, preferably around the perimeter of the body thereof to contact and seal against the coaming.
