Yacht rope extension, often called dynamic extension, is the extension of the rope under different tensions. Because the wind at sea is constantly changing, sailors often need to adjust the angle of the sail to get the best wind angle with the wind, or change the course by controlling the rope. These actions will unintentionally stretch the rope. So after using a normal rope for a while, you will find that it gets longer and longer. Sometimes people call it “resilience”.
It can be seen that the extension of the yacht rope refers to the behavior of the rope to lengthen the rope under constant tension. The original 50 meters lift rope can be used to become 55 meters. When the rope is stretched, the diameter will decrease and the tension will decrease. Sudden rupture is more likely in strong winds, which is potentially dangerous.
Therefore, the choice of rope should be low elongation, low elasticity, preferably pre-tensioned.
Creep of yacht ropes generally refers to long-term static stretching, that is, long-term elongation behavior of ropes under relatively constant tension, usually irreversible stretching behavior. In the case of sailboats, the common extension is dynamic extension, but if the rope is used for long-term constant weight, creep will occur.
You may wish to test. At the fixed point, use the yacht rope to hang the heavy object for a long time and record the height of the hanging on the ground. Record its height every 1, 2, 5 years and you will find the weight getting closer and closer to the ground, even on the ground. It’s a creep process, it doesn’t happen in minutes or hours, it’s a cumulative process.
