The list of appliances we're planning on having on the boat is: Washer / Drier / Dishwasher / Microwave / Fridge / Freezer / ...to name but a FEW. Moored in a marina over the winter, it'll be great to have all these. We currently have a low wattage washer...about 600Watts...but to be honest, using it through the winter is hard work.....something bigger is required. But....something bigger....does not compute with daily life out of a marina. Most people run their washer/drier when the boat is under way. At that point the alternators are working hard to recharge/supply batteries. Microwave is for marina use only. Elec kettle and hairdriers...all marina use only. Freezer...marina use only. So why not get a 12V fridge you ask ? The price, I say. I MAY look for one on Ebay....but only if I find one which is 12V AND 220V. (or 3 way with gas is even better). I didnt enjoy having to keep my batteries charged to the max, all through winter, just because my wife wanted the freezer on, and it was ONLY 12V...meaning I couldnt flip it over to 220V if I had wanted to. An unneccesary headache. The big question is....will we be in a marina most of the time or cruising. The answer....truthfully....in the marina...because our son starts college in the area in Sept....BUT.....I hate being in a marina....the Bridgewater canal is near by, and I am VERY tempted to stay on the River Weaver for some time, and put him on a train each morning. (Easier said than done). Darn it. I am going to try and do this the 220V way. Lots of batteries. Spare generator. Solar panels when I can afford it. I dont care. You have to make a decision one way or the other and MOVE ON.....there are other reasons....I dont like all those low powered, high current cabling you need for 12V appliances. 220V cabling throughout. Simples.
