ABSTRACT:
A hatch assembly for a marine vessel includes an outer frame and a hatch cover hingedly attached to the outer frame on one side thereof. The assembly also includes an elongated hatch adjuster comprising a telescoping rod assembly which includes an outer tube, a tubular extension and a flexible coupling which connects the tubular extension and outer tube in axial alignment when in a first position. The rod is slidably received within the outer tube and tubular extension and maintains the assembly in axial alignment as the hatch cover is rotated from a closed position to an angle of at least about 135.degree.. As the hatch cover approaches 180.degree., the rod is withdrawn out of the outer tube which permits the flexible coupling to bend so that the hatch cover can be rotated a full 180.degree.. The hatch assembly also includes a clamp for fixing the rod and outer tube in a fixed position to thereby maintain the cover in a preselected position with respect to the frame.
