Six essential dock and mooring knots, step by step, so you can tie off with confidence and stop guessing every time you pull into a slip.
Most boaters know three knots at best, and one of them is a granny knot they'd never admit to.
Nobody hands you a knot book when they sell you a boat. You learn on the fly, at the dock, usually while the boat is drifting sideways and someone is watching. These six will cover you for docking, mooring, anchoring, hanging fenders, and securing a line to pretty much anything. Get a piece of line and practice them tonight. You won't need to think about them again.
Before You Tie: Your Line Matters
A knot is only as good as the line it's tied in. For dock work, you want a quality dock line, not a piece of old rope from the garage. Marine dock lines are purpose-built: they absorb shock, resist UV, won't rot or mildew, and hold knots cleanly.
The three main types you'll see:
Diameter matters too. As a general guide, 3/8" works for most boats under 30 feet, and 1/2" for anything larger. When in doubt, go bigger. An oversized line costs you nothing except a few cents of extra material.
Knot 1: The Cleat Hitch
If you only learn one knot, make it this one. The cleat hitch is how you secure a dock line to a cleat, which is exactly what you're doing every single time you tie up. Done right, it holds under load, stays put in rough water, and still comes off cleanly with one pull.
When to use it
Tying off to any dock cleat, boat cleat, or mooring cleat. This is your primary tie-up knot.
How to tie it
- Lead the line to the cleat and take a full round turn around the base: go under the far horn and loop all the way around.
- Cross diagonally over the top of the cleat to the near horn, and wrap under it. You're starting your figure-eight.
- Cross back over the top diagonally to the far horn to complete the figure-eight.
- Finish with a locking hitch: flip the working end so it crosses under itself as it goes over the horn. The line should form a loop that you slip over the horn. Under load, this locks itself down.
The most common mistake is skipping the round turn at the start and going straight into the figure-eight. That single extra wrap is what makes the hitch hold under real load. Don't skip it.
You need a solid cleat to tie to. If yours are getting tired, we carry Kimpex nylon fender cleats: non-corrosive, no sharp edges, come with mounting screws. $20.99 for a 6-pack.
Knot 2: The Bowline
The bowline makes a fixed loop that won't tighten under load and won't slip. If you need to create a loop at the end of a line to drop over a piling, attach to a ring, or create a quick anchor point, the bowline is the knot.
It's also easy to untie even after taking serious load, which puts it ahead of most loop knots for dock use. Sailors have been tying bowlines for centuries for a reason.
When to use it
Securing a line to a piling or ring, creating a loop to drop over a mooring ball, attaching a spring line to a fixed point.
How to tie it
The classic mnemonic: the rabbit comes up through the hole, around the tree, and back down the hole.
- Make a small loop in the standing part of the line. This is "the hole." The working end should be coming toward you through the bottom of that loop.
- Bring the working end up through the loop from below: "the rabbit comes up the hole."
- Pass the working end around behind the standing part of the line: "around the tree."
- Bring the working end back down through the same small loop: "back down the hole."
- Hold the standing part and pull the working end and the large loop to tighten.
Leave at least six inches of working end when you finish. A short tail is a knot waiting to fail. The bowline won't tighten on itself, which also means it relies on that tail staying in place.
"Tie it ten times with a piece of line in your hand tonight. You'll never think about it again on the dock."
Knot 3: The Clove Hitch
The clove hitch is a fast, two-wrap knot that's great for temporary work: adjusting and repositioning a fender, making a quick tie to a rail, or securing a line to a post when you'll be moving again soon.
It's not a knot you want to leave unattended for long, as it can work loose under variable load. For anything overnight or in conditions, follow it with a half hitch or use a round turn and two half hitches instead (that's knot four). But as a quick and adjustable tie, it's hard to beat.
When to use it
Hanging fenders from a rail or lifeline, quick temporary tie to a piling or cleat, lashing anything to a round bar or post.
How to tie it
- Pass the working end over and around the post or rail.
- Cross over the standing part of the line and go around the post again.
- Tuck the working end under the second crossing, passing beneath the X you just made.
- Pull both ends tight.
For hanging fenders, the clove hitch is perfect because you can slide it up or down the rail to adjust the fender height without untying and retying. Set it, check the height, tighten it down.
On the topic of fenders: if yours need replacing, we carry Kimpex inflatable vinyl fenders in several sizes, including fender kits that come with rope included so you're not hunting for line. From $55.99 for a 2-pack.
Knot 4: Round Turn and Two Half Hitches
This is the more secure version of the clove hitch. It holds better under sustained load and is less likely to work loose in surge or chop. Any time you're tying to a ring, shackle, mooring buoy, or dock piling you plan to leave for a while, use this one.
When to use it
Tying to dock rings, anchor buoys, mooring balls, shackles, or any time you need something more secure than a clove hitch and there's no cleat available.
How to tie it
- Pass the working end through the ring or around the post, twice. That's the "round turn." The double wrap takes the initial load and holds the line in place while you tie the hitches.
- Bring the working end over and across the standing part, then tuck it under. That's your first half hitch.
- Repeat: bring the working end over and across the standing part again, then tuck it under. That's the second half hitch.
- Slide both hitches down snug against the ring and pull firm.
The round turn does the real work here. It's what prevents the line from sawing back and forth on the ring under load. Without it, even well-tied half hitches will chew through a line over time.
Knot 5: The Figure-Eight
The figure-eight is a stopper knot. Its job is to sit at the end of a line and stop it from running through a block, fair lead, or cleat hole. It's simple, reliable, and stays where you put it.
If you've ever had a line run all the way through a block and disappear, a figure-eight is the knot that prevents that. It's also a useful first knot to know just for recognizing when a stopper is needed in the first place.
When to use it
At the bitter end (working end) of any line to prevent runoff through a block, cleat hole, or fitting. Also useful as a quick hand-hold bump in a line.
How to tie it
- Make a loop by crossing the working end over the standing part.
- Bring the working end under and around the standing part, one full wrap.
- Push the working end back through the original loop from front to back.
- Pull both ends to tighten. It should look like the number 8.
Easy to remember, impossible to mistake once tied. Unlike an overhand knot (the most common mistake), the figure-eight doesn't jam as badly under load, making it easier to remove when you need to.
Knot 6: The Anchor Bend
Also called the fisherman's bend, this is the right knot for attaching your anchor line to the anchor itself. It's secure, stays reliable when the line goes slack (which happens constantly at anchor), and won't jam the way an overhand can.
The difference between this and a round turn and two half hitches is subtle but important: in the anchor bend, the first half hitch passes through both wraps of the round turn, not just around the standing part. That extra bite is what keeps it from slipping when load comes on at an angle.
When to use it
Attaching anchor line to the anchor shackle or ring. Also works for any situation where a line needs to stay secured to a ring and may need to handle load from varying directions.
How to tie it
- Pass the working end through the anchor ring twice, making two complete turns.
- Bring the working end up through both loops (not just the last one, but through both).
- Pass it around the standing part once and tuck it under for the first half hitch.
- Finish with a second half hitch around the standing part only.
- Pull firm. For a permanent anchor setup, seize the bitter end to the standing part with some whipping twine.
If you're setting up your anchor system from scratch, the Greenfield Anchor Buddy bungee cord is worth adding. It stretches to absorb shock on the anchor line so you're not jerked around every time a boat wake rolls through. Pairs well with a solid anchor line and a good anchor bend. $75.99.
One More Thing: Protect Your Lines
A good knot helps. What helps more is not putting a shock load on the knot in the first place.
A mooring snubber is an elastic strap that attaches between your dock line and the cleat. When wake, surge, or wind puts a sudden load on the boat, the snubber stretches and absorbs it instead of that shock going straight into your knots, your cleats, and your dock fittings. The Dock Edge mooring snubber is rated for both motor and sailing boats, and available in 6M and 8M lengths. From $48.99.
It's a small piece of gear that makes a meaningful difference on a floating dock or anywhere with regular boat traffic. Worth having.
The Bottom Line
Six knots. Cleat hitch for docking. Bowline for loops. Clove hitch for fenders. Round turn for rings. Figure-eight for stoppers. Anchor bend for the anchor. Learn those six and you're ahead of most people who've been on the water for years.
Grab a piece of line. Tie each one until your hands know the shape before your brain does. That's it.
