But, at the risk of seeming negative, since you completely
ignored my question I'll ask it one more time: what is the motivation
to use steam distillation even in "POWER boats with ENGINES running"
when the same amount of heat differential would give you vastly more
fresh water if you used it to run R/O filtration?


And, I'll answer it for you. Distillation requires little maintenance
and ALWAYS makes PURE water with the simplest carbon filtration. RO ONLY
makes "good water" when it's new and meticulously maintained, degrading
from that first moment you flip the switch until the bugs start leaking
through it making everyone sick.

Distillation requires me to decalcify the boiler once a year. I change
the carbon filter every few months of continuous use.

RO is FAR from perfect....especially a unit sold to some CONSUMER made of
the usual cheap crap. The cheapest consumer distiller makes the same
distilled water my commercial distillery makes....even if it's 10 years
old.

How'd I do? Are your glasses less rosey on RO?

One pinhole and the stuff will be loaded with chloride, dead simple to
detect. Add one drop of silver nitrate solution. Any cloudiness
indicates chloride, and it takes very little. This has long been the
practice on steam ships, with regard to the boiler water. And I don't
paint a rosy picture of RO, other than it takes less than one
hundredth the energy.
So boil the stuff you drink, and use the cheap RO water to wash down
the expensive boat. You can afford distilled drinking water. You ever
figure out what it actually costs for homemade electricity. It ain't
pretty. Salt water showers suck, and so does 25 cent a kwhr juice. The
old quadruple effect evaporators found on steamships used one tenth
the energy of an electric single stage still. Nobody said boats were
cheap.
