So I decided to stay in the water for the winter. I have a 1999 Carver 406 Aft Cabin, and I'm located on the Sassafras River near the top of the Chesapeake Bay. The plan is to stay on the boat certain weekends and keep it plugged in at the marina. They will run bubblers. My questions to all of you are these. Totally winterize? Water system, heat pumps, engines like I would if I pulled it out? Or, just keep the heat on with the heat pumps or some space heaters? (I'm not living on the boat. It's just an escape). Or, what minimally can I do to enjoy the solitude of my boat in winter without worrying about freeze damage? Your guidance and opinions are appreciated!
