Figure of Eight

A type of knot commonly used to create a secure stopper at the end of a rope, preventing it from slipping through a block, cleat, or pulley.

The Figure of Eight knot, also known as the “Figure Eight stopper knot,” is a fundamental and widely used knot in the maritime world. Its primary purpose is to act as a stopper knot, ensuring that the end of a rope does not pass through a fitting or opening, such as a fairlead, block, or sheave. The knot is named for its distinctive shape, which resembles the numeral 8 when tied correctly. It is simple to tie, easy to inspect for correctness, and straightforward to untie, even after being subjected to tension.

The Figure of Eight knot is particularly valued for its reliability and versatility. It is often used on sailing vessels to prevent halyards, sheets, or other lines from accidentally running out of their fittings. Additionally, it can serve as a temporary stopper until a more complex knot or splice is tied. While it is not intended for load-bearing applications, its simplicity and effectiveness make it an essential skill for anyone working with ropes in a nautical environment.
