Oh thats funny. When I took out my pontoon boat for the first time, I forgot my anchor at home. So I took some 30lb Maxima and wrapped it around 2 rocks. this kept me from spinning around in a cirlce, one for each side. I was lake fishing. When I was done, I cut the line, wrapped it up and threw it in the trash and let the rocks sink. Maxima save me that day.
