My sailboat has 3600 lbs of dead weight ballast. Seems like a real
waste to me.


So....Useless idea #3740

Make a boat with 60 lead acid batteries as ballast powering a high
efficiency 48 V motor. No diesel or gas, connect to shore power
overnight and you could have enough juice to go...........I dunno

Another story:

I have a friend who collects weird techno-surplus and sells it. He
bought several tons of lead bricks from a radioactive source
manufacturer that went out of business. Loaded it into the back of
his pickup and drove it to Tallahassee and parked on a hill. Of
course his parcking brake failed and the truck rolled about 10 feet
till it was stopped by a wall. There would have been no damage except
the entire load of lead bricks decided to slide through the cab. Not
sure what he told the insurance company.

I have about 500 lb of batteries in my keel on top of 8000 of lead.

Worked out fine but since the batteries box top is so low (just under the
cabin sole) I have make it water tight with external ventilation, higher up.

We sometimes go a week or two without shore power. How would you propose
keeping the batteries charged. The current technology for wind
generators and solar cells won't do it unless you covered the boat with
cells and put in a "farm" of generators.

Not true at all. We cruisied with a couple last winter that rarely had to
run the
motor to charge the batteries. They had 3 solar panels and a wind
generator. We are in the process of putting on a few solar panels but
with our wind generator alone we were able to do quite well. A little
further south into the trades and we would have been able to go for
many days or weeks without running the generator.

I don't think they were using an electric motor for propulsion - that is the premise of
this thread.

Add a genset to juice it up at max tuned efficiency, hot water,
fresh water, all hooked up to my roto tiller techumse, and
centrifugal bilge pump (who needs a switch?), propellor drive for
the motor / generator, home made hydrogen, and tow a hydrogen gas
fuel tank spinnaker with surgical rubber tubing lines, too? Why
not build a hydrogen zeppelin sail with lawn chairs, steel
ladder, with a towed submarine keel with control foils and
cables, like a 'water kite?'

Sky surfing!

A pound of diesel stores the same energy (on a practical basis -- not
the 20 hour rating capacity) as 200 pounds of lead acid battery.
That's why there aren't more electric boats and cars.

And, putting batteries in the bilge is one of those boating gotchas --
it's a great place for the weight until you get some bilgewater on top
of them.

So, keep thinking, Parallax.....
