� A knot uniting two ropes reduced the strength of the unit to about half f that of a weaker rope.
� A rope that is twice the diameter of another has four time its strength,
� Never use two ropes of different materials together, as only the more rigid rope will work under strain.
� Do not use ropes that will float for anchorage in ports, as they would be severed by the propellers of motor boats.
� Repair fraying ends immediately; apart from looking untidy, they quickly consume yards and yards of rope.
