ABSTRACT:
A hatch assembly includes a shaped lens or hatch cover and a rectangular shaped plastic frame member. The frame member includes an inwardly directed L-shaped cross section with an outwardly directed (away from the interior of the vessel) extension element at one end of one of the segments of the L-shaped cross section. The frame member surrounds the lens element or panel in a superposed and overlapping arrangement with a frame member abutting the vessel wall. The lens element is adjacent to and essentially surrounded by the outwardly directed extending element when the hatch is in the closed position. The hatch also includes a hinge for rotatably connecting the hatch cover and the frame member for opening and closing the hatch assembly and a gasket disposed between the outer peripheral area of the cover and the frame member. Releasable clamp member such as a dog and catch are provided for clamping the hatch in a closed position.
