Bill - I don't have any experience with your
request, just some thoughts. It seems that you want your
electrical system to power a lot, refrig, etc. It would seem
to me that it sure would take a lot of batteries and
therefore weight that I don't think a 22 foot boat would
easily handle, along with a gas generator and fuel. But
then again, you would not have the weight of an
engine. You mention Elco - I think they are the best
source for answers to all of your questions. Paul
