IMHO a day tank does not make sense on a small cruising boat. Big ships draw
fuel from "service" or "ready" tanks that are the same concept, but the fuel
is measured in tons rather than gallons and all the storage tanks are certain
to have a lot of seawater sloshing around in the bottoms, so stripping it in
transfer to ready tank makes sense.

Only on Navy combatants .... otherwise there'd better NOT be any
sal****er in those main storage tanks .... water, maybe some (from the
fuel) but not sal****er.
Main reason on larger vessels is to clean and for heavy fuel, to get to
right temp.

On the big ships I did contract work on, more than a few (maybe half?) had service
or ready tanks and transferred fuel daily. The really big diesels are apparently
capable of gulping in a few gallons of seawater now & then. The steamships aren't
any problem at all unless it is a big enough slug of water to put all the burners
out at once. Of course it's pretty bad for the machinery, but why complain when we
were making so much money fixing it?

A good thing, too. The wipers are *supposed* to check the seperator bowls at least
hourly, but I used to put notes on the seperators in big letters "Bring Me This
Note Immediately Upon Finding... $5 Reward" and had the whole watch go by.

Just this past weekend, I was explaining to a guy with a big motorsailer what a
"cleavage manifold" was. That's always been one of my favorite terms!

Doug,
I had a friend who told me they use sea water as ballast on bigger ships in
the navy, possibly CG. Of course, he's since gone mad and I can't confirm.

AFAIK most, if not all, freighters use water for ballast.
I loaded a box weighing 110K lbs. , onto a small ship in Balt. They used the
2 ship cranes to pick it. The ship heeled over when they tried to lift. Had
to wait what , seemed like an hour, to fill the starboard side ballast tank.

A good number of sailboats do as well.

what's a good number, 12 ?

12 is a pretty good number. However, I have always been partial to 8.

I probably should have mentioned that he said they sometimes put the water
in their fuel (bunker C or #6) tanks. At least I believe that's what he
said.

I would have bet against this, beforehand.
