§144.920. Window or portlight strength in a new vessel.

Each window or portlight, and its means of attachment to the hull or the deckhouse, must be capable of withstanding the maximum expected load from wind and waves, due to its location on the vessel and the vessel's authorized route.

Any covering or protection placed over a window or porthole that could be used as a means of escape must be able to be readily removed or opened from within the space.

Glass and other glazing materials used in windows of a new towing vessel must be materials that will not break into dangerous fragments if fractured.
