A knot or tight loop in rope or cord, or a nautical term for a type of hitch knot used to secure ropes.
From Dutch 'kinken' (to kink). Also possibly related to 'kink.' Used in nautical English since the 1700s as a technical sailing term.
A kinch is a sailor's best friend because it's a quick-release knot—you can tie it fast in rough seas and undo it instantly when needed, which could literally save your life!
