I'll have to turn this Q over to Bill. He has so many high tech things on his boat. I think he has 2 high capacity batteries and a charging alternator in the trolling motor in addition to the big one. I wonder if he put a power amplifying coil off the batteries, hooked in series/tandem, we could get a microwave oven to work?
Really don't need it with his propane heater/cooker. If it weren't environmentally unfriendly I'd suggest a light duty Honda generator up in his bow section outside the canvas cabin. The sky's the limit with that setup? - Steve
