Of course, I rarely try to start her below freezing, I don't want to sail then. I also find it takes a long cold time before the temp inside the boat falls below freezing.
WS,

Last winter your gave me a much needed fix of sailing. Are you going to let me reciprocate and go for a sail on our boat this winter?

Regards,
Brad

Thanks for the advice thus far. My fresh water tanks are in a locker in front (outside) the boat...catamaran. There's no heat there from inside the boat. I'm going to live aboard, so need the water. If the tanks were inside, no problem, they'd stay warm...this is a different case.

Then you really need the stick on heater I suggested. It doesn't take much to keep a tank warm. you could also put them on a timer, 4 on / 4 off around the clock for a start and adjust as needed.

Can you drape a black tarp over the area to generate a bit of Solar during the day?

Can you insulate the locker area a bit? Those foam pipe wrap tubes for house plumbing along w/ some "heat tape" for pipes running along the lines should do it and not kill you in elec. charges.

For 'outside' storage, I suggest that you:
1. apply 'heat trace' wiring to the INLET line of the tank(s) or to the connection to the 'bottom' of the tank - home depot stuff. The small amount of heat from the 'tracing' will thermo-siphon into the tank, especially if the traced line is LOWER (in altitude) than the tank.
2. always keep the water 'flowing' when the temp is 'severe' .... just a few drops / cc's-per-minute of flow, and routed 'back' to the tank will help prevent a total blockage of ice.

Also applies to 'inside' tanks when the weather is extreme - just keep the water constantly flowing and 'dribbling' back to the tank. For bilge tanks the ambient outside water temp (under the ice) will be ~4°C (39°F) and if you keep the tank 'slightly stirred up' (slight 'recirculation' by 'dribbling back to the tank(s)) you wont freeze. If the tanks are touching walls where the ice is in contact, then you need to 'warm' the tanks.

No experience with this. How about a fish tank heater (not bubbler).

Although, there must be commercial water tank heaters.

A couple of these in your tanks should keep it from freezing;


Could make the winter more interesting too...
