Meaning of "with a hose-pipe on him"

I'm listening to the song What shall we do with the drunken sailor and now can't understand what they advise to do with the drunken sailor:

Put him in the scuppers with a hose-pipe on him.

Scuppers is a draining system on a boat. I don't think it's big enough to put a man in there.

But the most weird phrase to me is with a hose-pipe on him.

How shall I understand it? Do they advise to cover the sailor with those pipes or use them any other way? How?

Please, help me to understand the metaphor.

Solution 1:

A hose pipe would be connected to a bilge pump to allow sea water to be removed from the bilges of a ship and ejected into the sea. Since ships' hulls were (and still are) not water-tight, this had to be done regularly, and was an arduous task in the days of manual pumps.

Drunken sailors were sometimes hosed-down with bilge water as a form of punishment. The sailor would simply be placed, face up, by the scuppers (where the water would drain off the deck immediately) and given a thorough soaking. It was far less dangerous than keel-hauling and much less painful than flogging, although there was possibly a risk of drowning, either on the bilge water or the sailor's own vomit. Perhaps we should consider it to be an early form of waterboarding.

P.S. Since I can find no reference to the custom as a form of punishment, it may simply have been used as a way of bringing a sailor out of a drunken stupor. The real punishment (if any) would come later. On merchant ships, it would probably have been a fine.
