sailaway...I really like the concept of the Yamaha but I read the pdf manual and concluded that it is really underpowered for charging duties as it only puts out 7.5 AC amps and 8 DC. It will take a LONG time running to put a charge back in your batteries at those rates and using an external charger will probably just overload the unit as it calls for more watts than can be delivered. Also...the rated 900 watts is only into a steady state load and drops off severely if motorized stuff is connected. I don't think it would be of much use on a boat and I think the little Honda's would be a better choice.
