Abstract
A port assembly for a marine vessel, including a lens element and three concentric stainless steel rings which are superimposed upon one another. A first of the rings includes a base portion forming an outer trim ring, a second portion which is generally parallel to the base portion and a sloping riser which defines an angle of between 105.degree. and 135.degree. with a base portion. The sloping riser also connects the base portion and the second portion. A second of the stainless steel stampings also includes a stepped cross-section with two risers and an intermediate portion connecting the two risers. The second of the risers also includes a sloped portion which is welded to the sloped portion of the sloped riser. A third stainless steel stamping, or clamping ring, is bolted to the intermediate portion of the second riser and, together with the base portion of the first ring, form a clamp for securing the port assembly to the wall of the vessel. The assembly also includes a hinge for pivotally mounting the lens element inwardly of the vessel's wall.
