ABSTRACT:
A hatch cover assembly for covering an opening in a vessel wherein a hatch port extends outwardly about the opening includes a hatch cover hingedly attached to the hatch port, and at least one latch assembly for fastening the hatch cover to the hatch port. The latch assembly includes a cam mount extending from the hatch port, and a first cam pin coupled to the cam mount. The first cam pin has a pin axis. A bolt member includes a first end and a second end, and the bolt member has a centerline axis extending between the first end and the second end. The centerline axis is generally perpendicular to the pin axis, and the first end is hingedly attached to the first cam pin about the pin axis. A securing member is in threaded relationship with the bolt member second end. The securing member is rotatable about the centerline axis of the bolt member. A cam member includes a cam lever portion and a clevis portion. The cam member is coupled to the bolt member by the securing member, and the cam member is configured to engage the securing member and adjust the threaded relationship of the securing member with respect to the bolt member by rotating the lever portion about the centerline axis of the bolt member.
