sesmith;
You must be a luck man. down here in the south without any treatment, you open that bailer up to allow air into the tank without the water being treated, you better run for them that hills.
I have been in youyr neck of the woods during winter and was it cold. We had a Capri 26 on a cradle. We washed the boat before making the trek. Ran into heck of a snow storm and to boot, the boat was being lifted off the cradle and one thing I never have seen since then. The cradle came up to with the boat as it was frozen to the hull.
