What is the percentage by which the strength of line can be reduced for hitches?

The strength of line can be reduced by 40 percent when using hitches. This reduction accounts for the fact that hitches introduce bends and twists in the line, which can affect its load-bearing capabilities. When the line is bent around an object or tied in a knot, the stress distribution changes, leading to a weakening of the line's overall tensile strength. Understanding this percentage is crucial for safe seamanship and proper rigging practices, ensuring that the line will hold during operations without risking failure due to overestimating its strength in practical applications. The practice of accounting for this reduction is essential for maintaining safety standards while working with various types of lines on a vessel.
