A porthole is a generally circular, window used on the hull of ships to admit light and air. Porthole is actually an abbreviated term for "port hole window". Though the term is of obvious maritime origin, it is also used to describe round windows on armored vehicles, aircraft, automobiles (the Ford Thunderbird a notable example), and even spacecraft.
On a ship, the function of a porthole, when open, is to permit light and fresh air to enter the dark and often damp below-deck quarters of the vessel. It also affords below-deck occupants a limited, but often much needed view to the outside world. When closed, the porthole provides a strong water-tight, weather-tight, and sometimes light-tight barrier.
A porthole on a ship may also be called a sidescuttle or side scuttle (side hole). This term is used in the U.S. Code of Federal Regulations. It is also used in related rules and regulations for the construction of ships. The use of the word "sidescuttle" instead of "porthole" is meant to be broad, including any covered or uncovered hole in the side of the vessel.
