It isn't Chicago or New England here. It may get into the 20s. I'll be sailing through the winter on weekends. What do I need to be thinking about? I assume 20 gal of vodka in the fresh water system isnt. serious suggestion
There have been some difficult winters up there so that is telling.My boat been floating in Puget Sound for ten winters and nothing has ever frozen, with me doing no winterizing other than relieving the pressure in the fresh water lines.
I just bought the boat so this is all new. Are there 12v heaters? With 3 house batteries, that should last long enough for the power to come on. I suspect that plan has its own problems.Do you keep a small heater on board? That seems to be a popular solution with two obvious dangers, the first being a source of fires, the second is how long it takes after a power losses to get some real damage to happen. We have had some pretty catastrophic blackout/freezing/storm combinations in Seattle in the last few years. If you are around and can get to your boat if that happens that may be ok. That's my plan.
Can you elaborate more on the switchI saw a heat based switch device at Home Depot that could be paired up with a space heater. That would probably work along with having all the doors and cabinets open. That assumes AC power is working. That should take care of most situations.
It sounds like not much else is necessary assuming regular use.
