I'm planning ahead for winterizing my sailboat which will be in the water during the winter near Nanaimo, BC on Vancouver Island. I will have a local handyman check on the boat periodically. I know the water doesn't freeze, and the climate is generally temperate, but it does drop below freezing occasionally. Is the fact that the boat is in the above-freezing temperature water enough to prevent the inside from freezing--ie. head, engine, water pumps, etc. I would prefer not to have to add antifreeze to everything if I don't need to.
I am getting conflicting information,
with some at the marina saying they never add antifreeze and have not encountered difficulty, and others disagreeing.
Thanks for any info. or advice.
