Where are you in relationship to Tsehum Harbour?
Just curious, how come you are going to decommission the boat for the winter? It doesn't get that cold there. No major freeze except for maybe 1 week max, and the sea water outside of the boat will keep the inside water above 32. Just pump out the holding tank, put a little antifreeze in the head, and that should do it. We shouldn’t need to drain the engine, raw water filter, etc. Around here, we have more mold and mildew problems than freeze problems.If you don’t use your boat during the winter, put a couple of goldenrods in your boat, or air circulators from West Marine, they are a flat round thing with a fan inside. You can also open all the lockers, ice box, and other enclosed areas to allow air flow. Stand your cushions on ends so they won’t collect moisture underneath.We use our boat during the winter, but not as often as during the summers, but at least once a month, maybe twice. During either Christmas or Thanksgiving, we usually like to go for a brisk sail, followed by going on the hook at somewhere secluded, cook a turkey in a warm cabin. What a joy.
