STRAIGHT GRAIN ALCOHOL !!!!! (FULL STRENGTH VODKA - 180 proof or 'moonshine' - 90% ) .....
FREEZING POINT for a 50:50 mix of water and ethanol is approx. -20°F
..... and you can 'recover' it in the spring ... to begin the 'festivities'.
I don't put anything in the fresh water tank to winterize it. I pump it as far down as possible and use an extractor to get the rest of the water out.This sounds too good and easy to be true?!?! Anybody try this? Any issues with the alcohol corroding the hoses or the components in water pump?

So what happens with the water in the pumps?
Find the water tanks manifold or connection to the pressure pump, disconnect the water line and using a drill-powered pump, pump the water to your bilge sump, or a bucket. Obviously it helps to have used up your tank first. Once the tank has been pumped down, leave the water lines, and pump open until spring commissioning. Use the same drill pump to extract water from your house system (open the taps) and then drive potable antifreeze (alcohol free) thru your house water system.On a Beneteau 321 there is a threaded pickup water tube in the holding tank, has anyone winterized the water system by threading a hose to the pickup tube in the tank. If so, what size is the thread?

So what happens with the water in the pumps?
I also use the same strategy written above. I disconnect the water supply just before the water pump. I have a 3 ft piece of hose with a connect on one end to attach to the intake of the pump. The other end goes in the anti freeze. Turn on the water pump and pump anti freeze (pink stuff) thru the pumps and out all faucets. I drain the hot water tank and have a bypass system so the antifreeze does not go in the hot water tank. Been doing that for 13 years...
