Another generator question

[StandUpGuy]

In a flat bottom sailboat often ballast is added on the floor of the boat to lower the center of gravity. Instead of adding lead I would add two marine batteries. This is good weight in a sailboat. Weight added to one end of the boat and up high as in an outboard is bad weight.

You, again, seem to have made up your mind before you asked the question....

Well if you look back at my original question I was just asking about generators and batteries, not whether I should use an electric motor vs. a gas one. I love talking about it however and I do love gas outboards. Had one on my old Coronado 27 sloop. Yes that had a several thousand pound cast iron keel.
