Re: [Electric Boats] Batteries as ballast

Geff , the best I have seen is on the "Hybrid Marine" site , on a yacht they converted to hybrid power .

Its on their site , under "batteries' , if I recall.

The concerns they had to address was ensuring that the batteries always remained dry , and that there was positive ventilation to the (huge) battery box .

From memory they used 24 2 volt batteries , quite a lot of ballast !.

Hi I have been lurking this site for a while thought I would finally post something. Has anyone actually built a monohull sailboat and incorporated the batteries as part or all of the ballast? My old 29 foot Colombia had a 4000lb lead keel. If even half of that had been batteries it would have provided a pretty good range wouldn't it? Of course it would require designing & building a boat with a keel that could accomidate the batteries. I was intrested if anyone has attempted to do this. Seems like it would aleviate some of the issues involved with modifiying an existing boat.
