If a window in a ship/boat is called a port hole, why are the windows on the R/H/S of the ship/boat not called starboard holes?

wikipedia has a resonable explanation.

It even describes port holes on submarines. Although, it doesn’t mention that these should, generally, not be opened.

Porthole, not port hole. Does that answer your question?

What about yachts?

from guns- portholes were originally for guns and when they became windows the name stuck – same issue though half the portholes were on either side no idea of the origin of that

Read wikipedia and i found the side scuttles(american term) but it doesn’t say why they’re called portholes on the starboard side of the ship or if it’s for a completely different reason.

‘port’ also means a hole giving access which is where the ‘port hole’ thing came from I suspect.

where as port/starboard come from;

Hopefully submariner training is more thorough than wikipeadia.

It would appear not.

Port, as in portal.

Portal makes more sense.

they’re so you can see when you’re in port.

That’s why.

When you’re out at sea they’re technically known as “out at sea holes”

HMS Thetis was lost off Liverpool with most of her crew when someone “opened the door” underwater. Tragically she was brand new & on sea trials. A test cock (hole) had been painted over, so the crew didn’t realise that the torpedo tube that they opened was open to the sea at the other end.
