In the PNW, If the boat is not in the saltwater, then you have to winterize.
In the salon is a different story even in the water. I turn off the pump and open all the sink valves, so they drain down during the cold periods. Last winter I forgot to take 6 cans of diet pop out of the fridge. All 6 froze and popped. 2 cans of regular coke didn't. I guess the sugar in them dropped the freezing point just enough to protect them.
The gallon jug of distilled water for the batteries in the engine room never freezes during the coldest weather. Even with no heat, other than Zantrex charger running on standby, which is nothing.
