No, no! Everyone knows a boat battery can be charged in 3 minutes if you
buy a big enough alternator!

Don't let logic, battery chemistry and me upset it.

I had a 1988 mustang ragtop that had about ten interior lights and a
small battery. If you left a door slightly ajar, the battery would be
completely, 0 volts, dead in 45 minutes or so. A ten amp charger would
put in enough juice to start it in ten seconds. Then comes the charge
from zero at the maximum rate. Needless to say, that battery didn't
last long.

Badly.

You would be much better off filling the freezer with a phase change
fluid that melts/freezes somewhere in the desired temperature range.
Water, for instance...

The exterior of a typical little bar fridge is a heat dissipation
surface, so insulating it from the surroundings would be a bad idea.

In practice high output alternators make a big difference getting up
to about 80% charge. That can be very, very useful. It may be that
you have some logic and battery chemistry in your text books but I
live on my boat and go voyaging a bit. High output alternators are a
good thing.

Bummer about the Smart Car. AFIK, they aren't importing the diesel
version because in CA you can't buy diesel cars w/less than 7k miles
on them. As they say the road to hell is paved with good
intentions... But, what you really want is a diesel plug in
hybrid...

As I'm sure you are aware, a real sailor will eat nothing but salt

for a fridge then usual.

The RN rum issue was originally a substitute for beer. Small beer, so
called, one per cent alcohol or so. It was sure as hell not
refrigerated.[or even iced]

That's what I admire about you Larry - a true lateral thinker.

Seriously.

I'd be interested to see what results you get.

The problem with the "household" type of fridge is the lack of
insulation. I just looked at one in a 45 ft. boat and it looks like
the compressor is running much longer then a "built in" with thick
insulation.

However, I am in the process of rebuilding an old motor cruiser and
plan to install a small house fridge as the boat will generally either
have the engines running or be tapped into a marina.

So do Larry, Peter and myself. (Well, larry doesn't live on one, he
just voyages).

Frankly, in my experience a 110 amp alternator and a 440 A.H. battery
bank is overkill,
