Wintering afloat in Canada

NCCL Blog   /  
I often get asked “what do you do with the boat in the winter?” For the past two winters, Grand Heron has remained afloat during the deep winter freeze. Keeping the boat floating free during that time is very labour intensive. First all plumbing systems, engines, generator and seacocks below the water line are winterized to prevent them from freezing. Next the boat is boomed in with cedar logs to keep moving ice from contacting the hull. Then we deploy 3 “ice eaters” as seen in the picture. These units run during subzero weather and they keep the perimeter of the boat ice free by drawing warmer subsurface water from below the ice. The decks must remain free of snow as the weight of the snow can push the boat down in the water potential creating stress. Daily checks are done to clear any ice that forms in very cold weather.Next winter we hope to dry-dock and winter the boat ashore which should be an interesting challenge to get this 107 gross ton vessel high and dry!
