As a kid in the eighties my friends family had a small yacht. I recall their fridge ran off gas. I know most fridges now days use electricity and lots of it. We are planning to do some extended cruising in a number of years and wondered what are the best options for refrigeration.

We currently only have a 40w solar panel and an 105 amp hour battery which does nicely for vhf, stereo, galley pump, lights and starter motor.

Guess we would almost need to double that setup ?
