How to Attach Anchor to Rope? | The Anchor Bend Explained

Attach rope to an anchor with the anchor bend, wrapping the rope twice around the shackle before passing the end through and securing it.

For the full breakdown, see our best Anchor Rope Claw guide.

Figuring out how to attach anchor to rope the right way matters more than most boaters realize. The standard knot for this job is the anchor bend, sometimes called an anchor hitch or fisherman’s bend.

One important distinction applies before any of the steps below: the knot at the anchor end and the knot at the boat end are different animals. The anchor bend handles the connection to the anchor itself, while a cleat hitch secures the line to your boat’s cleat. Mixing those two up is a common mistake that can cost you gear—or worse.

What Knot Attaches Rope to an Anchor?

The anchor bend is the go-to knot for connecting rope to an anchor shackle, ring, or eye. It’s been the standard for generations because it grips the hardware securely while staying relatively easy to untie after being loaded.

The anchor bend works by creating friction around the anchor’s attachment point. Two wraps around the shackle give it the holding power it needs, which is why the single-wrap version is a known weak point.

This knot is versatile enough for different anchor types, including the claw-style anchors popular on smaller boats. When the anchor is claw or plow style with an eye at the top, the anchor bend attaches the same way.

The Step-by-Step Method

Tying the anchor bend follows a clear sequence. Practice it once at home and you’ll be able to tie it by feel next time you’re leaning over the bow.

1. Pass the working end of the rope through the anchor shackle, ring, or eye from underneath.
2. Wrap the working end around the shackle a second time so you have two full turns of rope around the hardware.
3. Bring the working end behind the standing part of the rope, then pass it back through the two loops you just created.
4. Pull everything snug, taking out the slack so the knot seats firmly against the anchor.
5. Tie a backup knot—a simple overhand knot around the standing line—with the remaining tail to prevent the bend from working loose.

That backup step isn’t optional padding. Boaters commonly add a backup knot so they don’t lose the anchor entirely if the main knot shifts during a long session in choppy water.

Anchor Bend vs. Cleat Hitch: Understanding the Difference

The anchor bend secures the rope to the anchor itself. The cleat hitch is what you use at the boat end to tie off to a deck cleat. They’re separate knots for separate jobs, and confusing them is one of the most common rookie errors.

For the anchor end, the two-wrap anchor bend is your answer. For the boat end, a proper cleat hitch with a full figure-eight wrap pattern holds the line secure and releases cleanly when you’re ready to leave. If you’re setting up a permanent anchor line on a buoy, you might also consider a thimble and splice setup—but for a boat rode, the anchor bend remains the standard.

The anchor bend holds well in nylon, which makes the combination a solid choice for most recreational boats.

Common Anchor Attachment Mistakes to Avoid

Most anchor-loss stories trace back to one of these four mistakes. Knowing them saves you from learning the hard way.

• Using a single wrap instead of two. One turn around the shackle doesn’t create enough friction. Always make two full turns before passing the end through.
• Skipping the backup knot. The backup is your insurance policy. It’s what keeps the anchor on the boat when the main knot works loose.
• Mixing up anchor and boat knots. The anchor bend goes at the anchor; the cleat hitch goes at the boat. They aren’t interchangeable.
• Letting out too little scope. Scope is the ratio of anchor line length to water depth. Aim for at least 5:1, with 7:1 preferable in rough conditions.

Too little scope means the anchor pulls upward instead of digging in, and no knot will save you from a dragging anchor.

FAQs

Why does the anchor bend use two wraps?

Can I use the same knot at both ends of the anchor line?

No. The anchor end uses the anchor bend because it grips the shackle securely. The boat end should use a cleat hitch, which is designed to hold against lateral pull on a cleat and release quickly when you need to leave. Each knot is optimized for its specific job.
