REPLY 68 F now that might become a problem living aboard in winter. Having worked in boat building and more recently in design I doubt most normal production boats are insulated sufficiently to maintain that kind of interior temp full time. Some of the cored hulls have the equivalent of R 5 insulation value. A very few custom builds have R value of 8. this issue came up for a 58 footer design I was involved with. I had to determine how much air conditioning was required so I had to determnien the insulation value of the hull and superstructure. Supplemental insulation is definitely a must. R 12 is a minimum in central upstate NY. Having lived across Lake Ontario from that region I do have some personal experience to fall back on. <VBG> Sounds like it might be necessary to install a ceramic cube heater in the head to ensure adequate temp for composting to continue. That in turn brings up the issue of security of power supply. When I lived aboard; marinas in winter got last priority based on the premise that marinas was a summer occupancy issue. Oh sure. So when winter storms take out the utility power, it may take a day to restore power to an isolated marina under worst case condition. Where I live now this kind of delay could be three days. A day or so to plow out the roads, and tree clearing to occur before the hydro crews can get out to repair the downed power lines. Most people hereabouts rely on small to medium sized generators for back up. But that's another story. All the diesel fired furnaces I have worked on require electricity for fans pumps and what have you. And you need light during the periods of darkness. So any winterization has to include an adequate heat and power system. . > > I once saw 40 below zero in Colorado and had 1/4" of ice on the inside > windows of the car as I was driving to town.

Snow flies beginning of November and doesn't leave until first week in May. I was hunting for fire wood in the high country behind the house first week in June and got stopped by snow drifts to deep to drive through or over.
