Plan A is to be somewhere during the winter months where we do not need a heater. Having said that, we have found ourselves using Plan B on more than one occassion. We are currently wintering in North Carolina
which is definitely a Plan B although it has been fairly mild this winter so far. While at the dock
we use AC heat in the form of an oil-filled radiant heater with thermostat and we use a ceramic box-heater as a back up or additional. While at anchorage we use a product called a "Heater Buddy" which uses propane
and has an oxygen sensor that shuts off the heater if oxygen levels get dangerously low. So far this set up has worked fairly well for us and it is relatively inexpensive. If we were planning on spending more time in either higher latitudes or winter weather
we would certainly invest in something more permanent. Years ago (1979) we lived and cruised aboard a Morgan
OI 33 and we used a Shipmate kerosene heater; that heater was next to worthless. We were glad to see the trend of using propane
in bulkheaded mounted heaters. We should be out of here by the end of March, but in the meantime we have been very comfortable aboard our boat.
