Arch... what you are saying is TOTALLY impractical on a cruising sailboat. This is so ridiculous I can't even begin to refute it. Tell ya what...as soon as someone crosses the Atlantic or Pacific with their cruising electric motor sailboat and NO diesel...let me know. The FAQ's you reference are a complete joke and lack any substantive information. This is presently smoke and mirrors.
