Whipping Twine

Waxed twine bound around a rope end so the strands cannot unlay — the traditional finish.

INSPECT BEFORE LOAD · NEVER EXCEED WLL

Rope, splices and hardware are only as good as their condition. Inspect before every use and retire on evidence.

Overview

Whipping is the traditional way to stop a rope end fraying: a binding of twine wound tightly around the rope near its end, with the turns pulled down into the lay. It is the correct finish for any line that will be unlaid later, for natural-fibre ropes that cannot be fused, and for any end where a fused, shiny tip would be unwelcome in the hand.

The twine itself is usually waxed polyester, in the region of a millimetre in diameter. The wax makes it grip and holds the turns in place while you work, and polyester outlasts cotton in a marine environment. A common guide is to whip a length of about one and a half times the rope diameter.

There are several patterns. The common whipping is the quick version; the West Country whipping alternates half hitches on opposite sides for a finish that will not come undone if one end is lost; the sailmaker's whipping is sewn through the rope and is the most secure of all. For anything that matters, the extra minute is worth it.

Safety notes

A whip is a finish, not a load-bearing element. Never rely on whipping to hold a splice or a repair under load.
Cut the twine end short and seal it, or the loose tail will catch on everything the line touches.
Check whippings whenever you inspect a line; a whip that has worked loose means the end is about to fray.

Using it well

Pull each turn down into the lay with a spike as you go, so the whipping sits flush rather than proud.
Use a needle for a sailmaker's whipping on any line that will be handled hard.
Match the twine colour to the rope if the finish matters; a neat whip is a mark of good work.
