I agree with Eric, I can't see adding weight to an EP auxiliary sailboat. You have plenty of "ballast" to move around with the batteries if you need to change the way the boat sits on it's lines. I would sail the boat as it is and see if there are any trim issues.

If your boat is riding a little higher in back after the conversion, you can also see if there is any weight forward that you can take off the boat altogether. A lighter boat sails better and you'll need the electric drive even less. It's another step towards increasing the overall efficiency of your boat.
