I had a query several days ago regarding an article I wrote for Cruising World magazine about batteries and battery banks. The fellow loved the article (Thanks!) but had a good question that I should share with everyone. It has to do with wire sizing, specificall the main cable from his boat battery to in his case a small outboard engine. On his boat the battery is located forward, I think under a berthing area and a rather long cable runs aft to his outboard motor. Keep in mind that in this case we're talking about a small outboard engine on a sailboat, not that the type of boat makes any difference here. He was having trouble getting his engine to crank over with the electric starter.
