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.

What is claimed is: 1. A hatch cover assembly for covering an opening in a vessel, wherein a hatch port extends outwardly about the opening, said hatch cover assembly comprising: a hatch cover hingedly attached to said hatch port; and at least one latch assembly for fastening said hatch cover to said hatch port, said latch assembly further comprising: a cam mount extending from said hatch port; a first cam pin coupled to said cam mount, said first cam pin having a pin axis; a bolt member comprising a first end and a second end, said bolt member having a centerline axis extending between said first end and said second end, said centerline axis generally perpendicular to said pin axis, said first end hingedly attached to said first cam pin about said pin axis; a securing member in threaded relationship with said bolt member second end, said securing member rotatable about the centerline axis of said bolt member; and a cam member comprising a cam lever portion and a clevis portion, said clevis portion comprising a pair of first openings for receiving a second cam pin, said second end of said bolt member extending substantially perpendicular through said second cam pin for securing said cam member to said bolt member, said cam member coupled to said bolt member by said securing member, wherein said clevis portion further comprises an engagement portion having spaced apart sidewalls and a second opening, said clevis portion configured to be variably positionable between a first and a second position such that said securing member is positioned within said second opening of said clevis portion when said clevis portion is in the first position and said engagement portion engages said securing member when said clevis portion is in the second position, and wherein said cam member configured to engage said securing member and adjust the threaded relationship of said securing member with respect to said bolt member by rotating said lever portion about the centerline axis of said bolt member. 2. A hatch cover assembly according to claim 1 further comprising a secondary latch comprising an arm pivotally mounted to said cam mount about said pin axis, said secondary latch pivotal from an unlocked position in which said arm does not contact said hatch to a locked position in which said arm contacts said hatch. 3. A hatch cover assembly according to claim 1 wherein said cam member is rotatable about said second cam pin to engage said securing member. 4. A hatch cover assembly according to claim 1 wherein said lever portion is configured to be rotated about the first axis to adjust the threaded relationship between said securing member and said bolt member when said clevis portion is in the second position. 5. A hatch cover assembly according to claim 1 wherein said securing member comprises a nut comprising a plurality of sidewalls, said clevis portion comprises an engagement portion configured to receive at least two of said sidewalls, said engagement portion is configured to engage said sidewalls such that said cam member rotates said nut when said lever portion is rotated about said centerline axis. 6. A hatch cover assembly according to claim 5 wherein said engagement portion comprises opposed wall portions for contacting said sidewalls of said nut. 7. A hatch cover assembly according to claim 1 wherein said cam lever portion is movable with respect to said securing member in at least one of a rotational direction around said centerline axis extending through said securing member, in a pivotal direction generally towards said hatch cover, and in a pivotal direction generally away from said hatch cover. 8. A latch assembly comprising: a cam mount comprising a first cam pin extending therethrough; a cam shaft comprising a first end and a second end, said cam shaft having a centerline axis extending between said first end and said second end, said first end comprises an opening for receiving said first cam pin and for securing said cam shaft to said cam mount, said second end comprises a threaded portion for threaded engagement with a securing member; and a cam member comprising a lever end, a clevis end and a cam member axis extending therebetween, said clevis end comprising a pair of cam pin openings for receiving a second cam pin and a cam shaft opening, said second end of said cam shaft extending substantially perpendicular through said second cam pin, said cam shaft opening including an engagement portion sized to receive said securing member and said securing member configured to couple said cam member to said cam shaft, said engagement portion is configured to engage said securing member such that said cam member rotates said securing member when said lever portion is rotated about said centerline axis for adjusting the threaded relationship between said cam shaft and said securing member. 9. A latch assembly according to claim 8 wherein said cam member is movable with respect to said securing member in at least one of a rotational direction around said centerline axis extending through said securing member, in a rotational direction around said cam member axis, and in a pivotal direction generally perpendicular to said cam member axis.
