If you PM me I have never found a reasonable fresh water use. If a rope is bent around an object at least four (4) times its diameter, there will be no loss of efficiency due to bending. This reduction in strength is a result of the bends in the knot and associated stress-concentration points. Knot strength or efficiency (resistance to breaking, relative to the same rope with no knot) depends on the extent to which force (from loading the rope) is transmitted to any place where the rope is weakened (usually by a tight arc in the rope, or perhaps a place at which the The figure-eight knot’s strength lies in its ability to withstand considerable tension without loosening or coming undone.
