How exactly does one do that?
It's on a par with "opening the seacocks"

The boilers would have safety valves which no doubt vent somewhere
safely. Manually open them? Or far more likely have another valve
that opens to a safe vent.

do not vent to the funnels.

They vented up the side of the funnel and would have had easing gear,
which allowed them to be opened manually.

You would also have Boiler blow down valves which normally discharge
the water rather than steam first. In normal circumstance the outlet
is normally below the water line.
Ships chief engineers especially Geordie ones have an implant that
often makes them arrogant self righteous gits. I had a barney with one
when he accused me of not fully filling fresh water boiler feed tanks
on one ship before a voyage. Fortunately we got to the next port just.
Before we left I got him to witness the tank soundings himself,again
it was used rapidly so he checked a few things. Boiler blowdown was
leaking and the cock through the hull was as well. Did he
apologise,did he heck .
However in later years when he moaned about the cost of fresh water
when we had a good deck scrub in Port the retort "well when we throw
it over the side at least we know we are doing it " was enough for him
to scuttle away with a face like thunder.

You are fullof ****. Steam powered ships don't buy water. Do you
think it's like a caravan?

Ships distill sea water for cold water make up. In fact it is
distilled twice for the boilers and one for the crew.

Most of the boiler feedwater comes from the condensers where the
exhaust steam from the engines goes.
