Last night we had intense wind storms in CNY. I keep my grumman down by the water during the winter for easy access. The waves were massive yesterday. I have at least 10 feet of clearance between the water and the canoe. In no way did I expect this to be an issue. I checked the canoe before the sun went down and all was fine. This morning I found it in the drink. I had to get waist deep and attach a come along, but I was able to get it out. It was also had about 200 pounds of stones in it. It still looks completely sound which is surprising. Way to go Grumman!
