BOATING KNOTS: Loops
Scaffold Knot
A DURABLE NOOSE (SLIDING LOOP) OFTEN USED
WITH A PROTECTIVE PLASTIC OR METAL THIMBLE
More complex than the simple noose (or slipknot), yet
simpler than the hangman’s noose, the scaffold knot
(sometimes called the gallows knot) is a sturdy loop that
slides to fit snugly around a bar, rail, or other object. On
boats this knot is often tightened around a thimble, a
teardrop-shaped lining for the loop that protects the line
from wear, creating what sailors refer to as a “hard-eye.”
