This year I have decided to winter in the water at my marina in CT. I have done all the standard winterizing things like I usually do for wintering on the hard - including installing my canvas winter cover. However, I am haunted by the thought of my seacocks freezing and failing since I couldn't figure out how to get antifreeze down into them while in the water. Any thoughts on this? Hopefully I am over thinking it. Also any other suggestions or precautions for wintering "wet" would be appreciated. I am thinking of running an electric ceramic heater as well.
