A clove hitch is a quick, temporary knot used in sailing to secure a line to a spar, railing, mast, or piling. Formed by two consecutive half-hitches around an object, it is primarily used for holding moderate, constant tension, such as securing fenders to a lifeline. It is easy to tie and adjust but can slip under uneven loads.

Key Aspects of the Clove Hitch in Sailing:
Best Uses: Temporarily securing fenders to guardrails, mooring to a piling, and holding lines that have constant tension.

Limitations: It can slip or work itself loose if the tension is intermittent or if the rope is too slick.

Security Tip: Always add a half-hitch to the standing part for extra security.

Origin: Often called a "ratline hitch," it was historically used to attach rope steps (ratlines) to shrouds.
