Re: My last little bit of planning

Most LED running lights use 1-2 watts (usually 2 for the front, 1 for the back, 1 for the anchor). It can vary and older ones would be more.

Does your outboard have an alternator? That will normally supply 2-4 amps at cruising speed.

You need a shore power cable and battery charger to charge batteries from shore power. My Catalina 25 had a shore power cable, but no charger, so plugging it in didn't do anything for the batteries. A charger plus shore power cable cost more than the solar setup, though the cables aren't too hard to find used.
