What are these on old ships?
Discussion
They're inlets to "Dorade boxes" apparently. Must admit I didn't know what they were called before googling it mind.

I presume they've fallen out of favour on modern ships which have HVAC systems with a single intake instead.

They're ventilators from the era prior to the mass adoption of forced draft ventilation; loved by ship owners as they didn't cost anything to run, unlike the stuff that works, hated by crew as they were a load of s
t and barely better than nothing. When short of things to do the deck crew would be ordered by the bosun to adjust the ventilators so they pointed into the wind for maximum effect. They're also a pain to keep paint on as belting them with hammers is verboten, so it's strictly wire brushes and scrapers for prep.

Only on posh ships where the passengers/crew complain if they get a bit of water with their fresh air https://en.wikipedia.org/wiki/Dorade_box?wprov=sfl...

These ventilators are ofter in pairs for a certain area of the vessel, so one gets pointed into wind and its oposing one gets pointed away from wind to try and get some form of draft running through the area between them.
Only resorted to, if you could not open your cabin porthole, or it was too wet to sleep on deck.
As commented on before not very effective but it was oftern all you had on older vessels.
At sea away from prying eyes you would often find these vessels with all sorts of make shift scoops at each porthole to try and duct in some extra draft to keep your cabin cooler.

The box is just an optional bit at the bottom to separate air from water. If the ventilator is high up it's not needed.
