A port assembly for a marine vessel having an outer wall with an opening therein includes a shaped lens element, a pair of concentric plastic rings and a resilient gasket between the lens element and one of the rings. The plastic ring on the outside of the vessel is adjacent to the gasket and includes a pair of hinged brackets and a plurality of mounting members. A hinge assembly connects the plastic ring and lens element and allows the lens to be rotated inwardly to an open position and back to a closed position in which it is pressed against a gasket. One or more dogs are rotatably mounted on the mounting members for holding the lens element in a closed position. The second plastic ring is constructed and arranged to clamp the first ring within the opening and against the wall of the vessel. In a preferred embodiment of the invention, a decorative metal ring covers the exterior surface of the port assembly.
