Paul, we have been having a discussion on portholes vs scuttles on
another thread - "more photos from Varyag" - and need your expertise
vis a vis a round hatch cut in a square hatch. Do they still have

USN Sailor 101: Doors go through vertical walls, err, bulkheads. Hatches go through floors, <ahem> decks. A scuttle is a small, usually circular passthrough, most often in a hatch but sometimes in a door. A scuttle can be used to pass people or material when the main hatch or door is closed in conformance with the material condition set at the time, minimizing the risk of flooding while the scuttle is (briefly) opened.
