In a self-draining, leak-resistant boat window, in combination: (a) a frame body comprising a continuous mounting flange for engagement with an inner surface surrounding an opening in the wall of a boat, (b) said body including a spigot connected with said flange and defining the window opening and having a lower portion characterized by an upwardly-facing drain surface constituting a sill, said spigot being adapted to extend through said wall opening of the boat, (c) a window pane for closing off the window opening formed by the spigot, and (d) means hingedly connecting said window pane to said mounting flange, (e) said sill of the spigot having a portion which is downwardly offset with respect to remaining areas of the sill, said downwardly offset portion being provided with a sloping drain groove extending from a high location closely adjacent said mounting flange to a low location disposed remote from the mounting flange (f) said drain groove being open at the top for a substantial portion of its length, thereby defining an open channel which resists the tendency for residue to form therein and cause possible clogging. view more
