C22 in northern winters
Dan: My 1974 C22 has never had a freezing problem through Wyoming winters. It starts out with the bilge dry and is covered with a "haystack cover" and left alone outdoors and unattended October thru May. I also blow out any water from the "galley" water tank and sink drains. I try to support the tarp in the cockpit area from beneath with plastic garbage cans, and I put in wooden blocks between the spreaders and the cabin top to avoid snow loading problems. During winter, some precipitation water does get into the cockpit area during thaws, but most drains OK and much evaporates in our climate. The rest,if it freezes cuases no damage because it is not contained in a tight space. I used to remove the battery, but have not during the past 4 winters, rather leaving it well charged and all wiring leads removed. I think a trickle chaarge solar cell would be nice too as voltage does drop overwinter and if it ever gets too low the electrolyte may freeze and break the plates and/or case. One winter was spent in Oregon in this "winterized" condition without freezing problems, though the extra moisture was good for molds in the cockpit area requiring more spring elbow grease than I'm used to.
