Abstract
A vented hatch cover for an enclosed vessel having a shell member sized to overlie and cover a hatch opening defined by an upstanding coaming. It includes a peripheral seal to seal against coaming. The shell member has at least one air passage extending through it. A wall is integrally formed on the shell member and defines a plenum in communication with the air passage. The wall extends outward beyond the peripheral seal and there defines an air intake opening for admitting air to the plenum. An air filter is housed in the plenum.
