Your more than welcome.
1) I am still unsure of how electricity runs on a sailboat? Can you have a small fridge and dvd player (creature comforts) on a live aboard sailboat? or is it all igloo coolers and crackers?
You can pretty much have what ever you want depending on how big your boat is and how many of the expensive "Deep Cycle" batteries you want to buy and maintain. They'll have to be kept charged, which can be done when at the dock or underway using wind or solar power.
