ABSTRACT:
An integrally-formed portlight for installation through a sidewall opening in the cabin or hull structure of a marine vessel has an inwardly-projecting, rectangular spigot portion within which a rectangular light or screen can be selectively fitted. The light is hingingly supported along its top edge within the spigot to provide for upward opening to the inside for substitution of a rectangular screen, the screen being received, along an upper marginal edge portion, within the groove between the upper edge of the light, when withdrawn, and a peripheral shoulder formed within the spigot. Lower end portions of the light or screen are clamped in place against the peripheral shoulder of the spigot with use of elongated clamp-screws threadingly received in upstanding brackets secured to outer end portions of the spigot along the bottom wall thereof.
