portlights

Vessel's round openings

Portlights are small windows in the side of a ship or boat, typically round or oval and often hinged to open for ventilation.

The term is essentially synonymous with portholes, though portlights may specifically refer to those designed to admit light rather than provide a view: The cabin had two portlights that let in a pale gray glow.
